From Police Program to Pregnancy: The Full Story of Sandra Birchmore’s Homicide

December 15, 2025 / 48:36

This episode covers the tragic case of Sandra Birchmore, her suspicious death, and the subsequent investigation involving police misconduct. Key discussions include the role of Stoughton Police Chief Donna McNamara, the internal affairs investigation into officer Matthew Farwell, and the systemic issues within the police department.

Sandra Birchmore was found dead in her apartment in Canton, Massachusetts, on February 4, 2021. The police initially ruled her death a suicide, but Chief McNamara opened an internal investigation after learning of Farwell's alleged affair with Sandra. The investigation revealed disturbing text messages and a pattern of abuse.

The episode highlights the troubling dynamics of the police Explorers program, which Sandra was involved in as a youth. Chief McNamara's findings indicated that multiple officers, including Farwell and his twin brother William, had inappropriate relationships with Sandra.

Despite the evidence, the Norfolk District Attorney's Office declined to press charges, leading Sandra's family to file a wrongful death suit against the officers involved. The episode concludes with the ongoing FBI investigation and the arrest of Matthew Farwell.

This case raises significant questions about accountability and the protection of vulnerable individuals within law enforcement.

TLDR

Sandra Birchmore's suspicious death leads to police misconduct revelations and an ongoing FBI investigation into officer Matthew Farwell.

00:00:01
What I'm about to brief you on is something deeply troubling to me as a human being
00:00:10
and as a police chief. On February 4th, 2021, 23-year-old Sandra Birchmore was found deceased in her apartment
00:00:23
in Canton. [music] What I am here to talk about today is her life and how she was failed by,
00:00:31
manipulated by, and used by people of authority that she admired and trusted right up until her final days.
00:00:43
Ms. Birchmore was a vulnerable person who had one constant in her life since childhood.
00:00:54
Her unwavering admiration of police officers, of those serving the military, people in uniform,
00:01:05
people with oaths and duties to protect and serve. The admiration led her to form relationships
00:01:14
with men who were willing to take advantage of her. I stand before you today as a civil
00:01:22
servant who is heartbroken >> [clears throat] >> and incensed by what has transpired
00:01:30
and who pledges to this that this chapter in the Stoughton Police Department and the town of Stoughton
00:01:41
is over. It must never repeat. The revolving door is closed. There are so many stories we tell that
00:01:55
involve corruption, cover-ups, or just downright incompetence or negligence that it makes me lose complete faith
00:02:02
[music] in the system. A system that is put in place to protect us. And doing the show for as long as I have, I've
00:02:08
seen a lot more bad than good. The problems are systemic and at times I've even caught myself thinking like, what
00:02:16
is the point? Like we might as well just give up because the problems are so big
00:02:20
and have been there for so long that maybe I'm the delusional one and this is just how the world is, evil. And the
00:02:27
evil is so like deeply rooted that we're never going to win or never going to make a difference.
00:02:33
But then, when I need it the most, I get a glimpse [music] of the good ones. The
00:02:38
people who are fighting from the inside to make things better and fair and just.
00:02:43
People who believe in right and wrong and know that no one is above the law. >> [music]
00:02:48
>> And those people give me hope all over again to keep fighting myself. And I felt all of those feelings when covering
00:02:56
today's story. Despair that an entire agency could look the other way when so much evidence was
00:03:02
at their fingertips suggesting [music] a boy in blue might have killed a young woman to protect his reputation.
00:03:09
And then this fire to kick ass and take names [music] and get behind those people like Donna McNamara, the chief of
00:03:17
the Stoughton PD who you just heard at the top. She didn't just sit back [music] and let it be. She found her own
00:03:24
way to expose the truth and she lit a spark that other good people out there doing the right thing [music] fanned
00:03:31
into a flame to get justice for Sandra Birchmore. So let me tell [music] you how that
00:03:37
happened. February 4th, 2021, 23-year-old Sandra Birchmore was found dead in her Canton,
00:03:50
Massachusetts apartment. Police discovered her body while responding to a welfare check requested by someone at
00:03:56
the school where she worked because she hadn't shown up in days. Now, Sandra was found in a seated
00:04:02
position on the floor by her bedroom closet with this [music] duffel bag strap wrapped tightly around her neck
00:04:08
and fixed to the handle of the closet door. The Massachusetts State Police didn't note any signs of forced entry to
00:04:15
her apartment. The door was actually locked and they had to get a key from the property manager just to get [music]
00:04:20
in. And once they were inside, they didn't see any signs of a struggle at all in the bedroom or anywhere else in
00:04:27
the apartment. The walls didn't have any indentations or scuff marks and there were no drag marks on the floor or
00:04:34
anything like that even though the apartment was cluttered with baby items still in boxes for the child that Sandra
00:04:40
was 8 to 10 [music] weeks pregnant with. Nothing seemed to be knocked over or moved and surveillance footage from her
00:04:48
apartment complex's lobby shows Sandra coming and going [music] alone on Monday, February 1st, which is the last
00:04:54
day she appears on camera and the day that officials believe she died. So, the suicide determination came quickly. Even
00:05:02
before the medical examiner's official ruling, all the Canton PD reports discussed this case as a suicide.
00:05:10
And the Massachusetts State Police seem to agree. Cuz I'm sure the more they learned about
00:05:15
Sandra, like it just began to confirm their theory >> [music] >> because she grew up struggling. Dad
00:05:21
wasn't in the picture, mom had chronic health challenges often times not being able to work so they struggled to make
00:05:27
ends meet. And from a young age, Sandra sort of took on the role of caretaker. And then in 2016, when Sandra was just
00:05:34
19 years old, her mom died of a stroke and then just weeks later her grandmother passed away, too.
00:05:40
According to an unnamed source in a Boston Globe article, after these back-to-back tragedies, Sandra began
00:05:45
[music] expressing suicidal thoughts in her journal entries. And she tried living with other family
00:05:50
members after this but she never really had that stable home base. And there was an instance like 8 or 9
00:05:57
months before her death where Sandra got in a fight with the family member that she was living with and stormed out.
00:06:03
That person called 911 concerned that Sandra might be at risk of hurting herself.
00:06:08
Now, at the time of her death, she was about 2 and 1/2 months pregnant with what investigators would quickly find
00:06:14
out was a married man's baby. So, it must have all just been too much. How sad. And when a pathologist from the
00:06:23
office of the chief medical examiner agrees and rules this case as suicide, that's that.
00:06:29
And there is a world where it would have ended right there. But not this one. Not this time.
00:06:37
You see, even though Canton PD was the agency originally called and Massachusetts State Police eventually
00:06:43
took over, the Stoughton Police Department opened an internal affairs investigation the day after Sandra was
00:06:49
[music] found. >> And where in relation to all this is Stoughton? It's just a town over from
00:06:53
Canton. But the reason they're in the mix is because of who Sandra's baby daddy allegedly was.
00:07:00
You see, Chief Donna McNamara heard from the Massachusetts State Police that one
00:07:05
of her officers, a man named Matthew Farwell, may have been having an affair with Sandra. [music]
00:07:11
And that would have violated department policies because I mean, put him married
00:07:16
with kids aside, Matthew Farwell was an officer who worked with their police explorers program.
00:07:23
And Sandra, in her youth, was an explorer. And Brett, I know you know all about the program cuz it came up in our
00:07:29
live show but for the newbies out there, do you want to give them the lowdown? Yeah, this will be very surface level
00:07:34
but the explorers program is basically like an extracurricular program run by local law enforcement agencies and it's
00:07:41
open to anyone from the ages of [snorts] like what, 6th grade to 20 years old who are interested in joining law
00:07:48
enforcement one day. It's sort of like a junior police academy. They wear little
00:07:51
uniforms, learn about investigations, do ride-alongs, even apparently search for
00:07:56
evidence sometimes. [laughter] Usually the program is led by actual officers from the local department so
00:08:01
the kids who sign up get really [music] close to them which can be a really great thing in some cases but
00:08:09
potentially really dangerous in others. >> You are correct. Okay, so I was about to
00:08:15
ask if the state police knew about this but if they're the ones who told the chief in Stoughton, then they had to
00:08:20
have. >> Yeah, they did. And they were looking into it, too. Despite many files that
00:08:25
refer to Sandra's death as a suicide, it does seem like they were still doing some legwork, like checking boxes,
00:08:32
making sure they didn't miss anything big like the affair with a married officer.
00:08:36
>> Right. And they even talked to him, collected his and Sandra's phone data. And in
00:08:40
their interview with him, which takes place on February 6th in a school parking lot for some reason,
00:08:46
Matthew admits that he was at Sandra's apartment that night. I'm sorry, what? >> Yeah, so remember the surveillance video
00:08:55
that showed her apartment lobby, right? She's coming and going. >> coming and going by herself.
00:08:58
>> Mhm. Well, it didn't just show her coming and going. And just a quick FYI, the footage was found to be 13 minutes
00:09:05
off so the times I'm going to be telling you have been adjusted for accuracy but
00:09:09
basically, Sandra gets home early from school because they had closed for a snow day on the 1st. A few hours later,
00:09:15
after 5:00 p.m., she's caught on camera again picking up a food delivery. And then at 5:31 p.m., she's seen one last
00:09:22
time stepping outside briefly to brush the snow off her car and then heading back upstairs.
00:09:26
And that's it for Sandra. But they did look at the rest of the footage to see if there was [music] anyone else
00:09:32
suspicious on it. And the maintenance supervisor at the apartment building tells officers that he recognizes
00:09:38
everybody who enters the lobby that night except for one person. [music] This tall, burly man wearing boots,
00:09:46
jeans, a black jacket with a hood up, and what looks like a COVID mask which almost entirely covers his face.
00:09:54
Now, he entered the building at 9:14 p.m. and then left at 9:43. And the police report notes that the man
00:10:02
wasn't wearing gloves and appeared to be white. And that's Matthew. I mean, we know now that it was Matthew
00:10:10
because he is admitting it to police on the 6th, but at the time it's a little hard to tell what they knew because this
00:10:17
part of the police report is pretty heavily redacted. All I know is that one of the building worker says that they
00:10:22
had seen this guy with Sandra before, but they didn't know who he was. And the leasing manager starts giving
00:10:28
them at that point some information about a police officer [music] that Sandra had been in a relationship with
00:10:33
and how there was something that he was unhappy about that Sandra was nervous about. But honestly, it truly is almost
00:10:39
impossible to make sense of this person's account with all of the redactions to the file.
00:10:44
>> Right, you're kind of just like barely able to kind of almost connect the dots.
00:10:48
>> Right. So, they were probably suspicious, but now they like know, now it was him,
00:10:53
right? And his story seems to again confirm their original hypothesis because he says that he met Sandra in
00:11:00
the Explorer program. She was 13 when she joined, he was 24, but he says that like nothing untoward happened. Matthew
00:11:07
says that he knew Sandra had a troubled life and he felt bad for her, so he would like keep tabs on her over the
00:11:13
years. But according to him, the relationship didn't become sexual until early 2020 when Sandra would have been
00:11:19
21. And that only happened because he says he got drunk one night and quote ended
00:11:25
up meeting up with her and having sex. And then he says that they had sex two or three more times after that with the
00:11:30
last time being in October of 2020. So, does he say that they were like dating? Like, how did he classify the
00:11:39
relationship? Were they together? Well, so like I said, so he's married with two
00:11:43
kids at that time. So, at least on his end this was very much not a public like relationship situation. But he goes on
00:11:50
to say that in December of 2020, Sandra told him that she was pregnant and that he was the father. Now, in his
00:11:57
interview, Matthew says that that wasn't possible and that the timeline didn't make any sense and just basically
00:12:03
adamantly denies that he was the father of Sandra's unborn child. >> Okay, so then cut to the chase, Matthew.
00:12:09
Why are you at her apartment the day she died? Yeah, so he says that that night he asked Sandra if he could come over
00:12:14
because he wanted to end things with her once and for all. He says that he hadn't
00:12:19
seen her in about a week because he'd been trying to distance himself, but that was before he learned that Sandra
00:12:24
was now telling people that he was the father of her child. So, he went over that night and said that he told Sandra,
00:12:31
quote, she was crazy and that there was no way he could be the father of her baby based on her timeline and that he
00:12:37
was just done with her. He said that the two of them kind of got into this pretty nasty argument, not
00:12:42
anything like yelling or physical, but just like really tense. And before he left, he told her it was
00:12:47
really over and he was blocking her on everything, which he did. And Matthew says Sandra was definitely upset, but
00:12:53
that she didn't say anything about wanting to hurt herself. And he told police that she was very much alive and
00:12:59
standing in the kitchen when he [music] walked out. Now, they asked him to take a polygraph and submit to a DNA test,
00:13:06
presumably to verify his claim about the baby not being his. But none of those things end up
00:13:10
happening because Matthew gets an attorney who steps in. And this attorney, Patrick Hanley,
00:13:16
actually writes a letter to an MSP sergeant saying that these requests don't make any sense for the
00:13:21
investigation of a witness, which is what MSP had said [music] Matthew was. I actually have a quote from Patrick. It
00:13:27
says, "I advise my client to decline these requests and the request for further interview that accompanied them. I did
00:13:35
so because they are far outside the norm for mere witnesses in an investigation.
00:13:40
I was a prosecutor for 14 years and participated in hundreds of interviews with state police detectives like
00:13:45
yourself. I cannot recall one seeking a polygraph interview. And I can only recall seeking DNA of persons that the
00:13:51
investigators and I considered targets. Mr. Farwell has already provided highly personal information. In my opinion,
00:13:58
providing DNA is a step too far." End quote. The lawyer also underscores that Matthew
00:14:05
had nothing to do with Sandra's death, that he never encouraged her to harm herself or believed that she might. And
00:14:12
according to him, Sandra's death by suicide was a complete shock to Matthew. The thing Matthew does comply with is
00:14:19
turning over his phone, but he warns that he deleted all the communications with Sandra. Okay, that's fishy, right?
00:14:26
Like, they see that that's at least sus, right? They don't say. We just have a report that is very black
00:14:34
and white and I I even brought this one. So, it just says, "On February 9th, 2021, Matthew Farwell consented to a
00:14:43
data extraction of his personal iPhone 11, which was then extracted by Trooper Nick Garrino. On April 26th, 2021, I
00:14:51
received Matthew's work cell phone from Stoughton Police Department. Through Matthew's attorney, consent was given
00:14:56
for a data extraction, which was performed by Trooper Nick Garrino. I analyzed both of these phones and did
00:15:01
not find any communication with Sandra Birchmore. Matt has said in a previous interview that he had deleted all
00:15:07
communications with Sandra. So, there's no like, oh, we think this was weird or not.
00:15:11
>> well, didn't see anything. Right. So, Trooper Nick Garrino went through this,
00:15:16
we know this, but another state police sergeant had started combing through Sandra's laptop that was collected from
00:15:23
her apartment. >> The other end of the communication. >> Right. And so, he finds in that
00:15:28
thousands of text messages between Sandra and Matthew [music] in the 12 months or so before her death.
00:15:34
Now, the state police write that the text messages make it clear that Matthew and Sandra were in a sexual
00:15:39
relationship, but they concluded that there was nothing threatening [music] at all.
00:15:44
So, they must just be assuming that he deleted the messages to hide the affair. Nothing murdery here, so
00:15:51
case closed, right? Wrong. Cuz Stoughton PD was running their internal affairs investigation
00:15:58
alongside this one. >> [music] >> And in reviewing over 32,000 messages between Sandra and Matthew in the 14
00:16:06
months leading up to her death, they see a far more disturbing picture of Sandra's case.
00:16:17
Some cases fade from headlines. Some never made it there to begin with. I'm Ashley Flowers and on my podcast [music]
00:16:24
The Deck, I tell you the stories of cold cases featured on playing cards distributed in prisons designed to spark
00:16:31
new leads and bring long overdue justice because these stories deserve to be heard and the loved ones of these
00:16:38
victims still deserve answers. Are you ready to be dealt in? Listen to The Deck now wherever you get your podcasts.
00:16:47
So, the chief of Stoughton PD, Donna McNamara, opened that internal affairs investigation into Matthew Farwell the
00:16:54
day after Sandra was found because she had heard from MSP about Matthew potentially having an illicit affair
00:17:00
with Sandra violating department policies. So, she put Matthew on paid leave starting February 24th. And again,
00:17:07
just to be 100% clear, her internal investigation was only meant to look into Matthew's misconduct, [music]
00:17:14
not Sandra's death. >> Right. Chief McNamara and MSP had an understanding that MSP basically still
00:17:20
maintained the jurisdiction over any criminal [music] activity, even like anything that comes up in the internal
00:17:25
investigation. And if the chief found any criminal culpability, she would basically pass all of that off to MSP.
00:17:31
So, like, sure, fine, whatever. That's the deal. >> not looking for it, but if she sees it,
00:17:35
she'll hand it over. >> Yeah, I'm not going to take it. So, her team starts looking at the phone
00:17:40
data and the laptop that was previously analyzed by state police Trooper Nick Garrino. [music] And these messages,
00:17:46
which appear in federal and court documents, don't only suggest that Sandra and Matthew's sexual relationship
00:17:52
began way before he originally said, but also that Matthew had disturbing sexual
00:17:59
fantasies involving [music] violence against women, choking, incest, pedophilia, necrophilia, and rape.
00:18:08
And I want everyone to hear some of these messages so you guys can get an idea of the tone of the communication
00:18:13
between Sandra and Matthew. So, I'm going to have a voice actor reading them because they are really disturbing, so
00:18:19
like fair warning to everyone listening. >> [music] >> And also, I don't want to look you in
00:18:23
the eyes while I say feel him inside me. But I think this shows the full extent of Matthew's behavior. So, in a couple
00:18:31
of exchanges, Matthew [music] and Sandra talk about the beginning of their sexual
00:18:36
relationship. What was the first day you said, "OMG, I want this guy to be my first. I want to
00:18:42
feel him inside me." Yeah, so 2012 I finally decided that I was going to try and find a way to you
00:18:49
and just wasn't sure how. I had butterflies so bad the day you took my virginity.
00:18:54
Me, too. It was such a big day. It was April 10th, 2013. Best day of my life. Me, too.
00:19:02
So, the sexual relationship actually began 7 years before Matthew told police that it began. Yes, and he actually even
00:19:12
says that he wishes they'd done it sooner. I wish it had been a year sooner after
00:19:17
helping you study at the library. I didn't even make you wait a year after that. I absolutely would have you in 12.
00:19:24
In 12? 2012. And in 2012, Sandra would have been like, what? >> like 14 or 15. And he knows that this
00:19:35
would have been bad for anyone else to find out, so he asked her to get rid of their messages.
00:19:41
Clear that pod out, baby. I did. Good girl. Again, I know how disturbing these are,
00:19:48
but I really think it's important for our listeners to understand the power that Matthew knew he had over Sandra,
00:19:54
mentally and physically, by the way, because Sandra was 4'10", Matthew was 6'4". So, in one exchange, he says,
00:20:03
"lol, if I pushed, I absolutely could have you without condoms from day one." "I was kind of scared to say no in the
00:20:10
beginning, not knowing how you'd take it. So, yeah, you would have gotten no condoms."
00:20:16
Other messages from Matthew revealed even more disturbing desires. "Maybe I'll choke you a little. I'll
00:20:23
grab your throat and say, 'You won't say a word to anyone.' Will you say, 'Matt, stop. I'm 13. I'm
00:20:29
not ready for this. Oh, I'm FG, please stop.'" According to sources cited in the Boston
00:20:36
Globe, in the year leading up to her death, there are at least 20 times that Matthew texted Sandra about grabbing her
00:20:43
throat, squeezing her throat, or choking her during sex. In another exchange, Sandra asked,
00:20:50
"Do you want me to just take what you do, or try and say no? I know being told no is your favorite." "Say no."
00:20:58
Now, of course, all of these messages are from [music] 2019 onward. So, we have no way of knowing what Sandra and
00:21:05
Matthew's communication was like before that. But, in December of 2020, things took a notable turn.
00:21:13
That's when Sandra texted Matthew about her pregnancy. That's when she sent him a photo of a colorful poster that she'd
00:21:18
made with the word "Congrats, we're going to be parents." >> [music] >> And this is how he responded.
00:21:24
"I literally have nothing to say right now. How could you express that in text when I said I don't appreciate it?" "I'm
00:21:30
mad you're acting how you are over a choice we both made." "I'm mad you act like you gave anyone a choice. You are
00:21:38
truly the worst person on the face of the earth." Matthew also asked how far along Sandra
00:21:44
was. "Regardless of how far, we're keeping it. But, 3 and 1/2 weeks, which means I
00:21:51
conceived this month." "Okay. Well, we need to talk, then." "No [ __ ] that's obvious."
00:21:59
And on December 29th, 2020, they did talk. This conversation was in person, so we have no way of knowing exactly how
00:22:06
it went. But, [music] afterwards, Sandra texts Matthew this. "It made me really uncomfortable and
00:22:12
stressed out and scared when you were next to me, because I thought you were going to hit me after you said what you
00:22:18
said and took things out of my hand. That's why I was crying." "I know you wouldn't, but it still scared me."
00:22:25
So, clearly, he's not happy about the pregnancy. >> I mean, yeah. It's a lot harder to hide
00:22:31
from your wife than just an affair. Well, and [music] at an especially bad time, because I didn't mention this yet,
00:22:38
but when Matthew left Sandra's apartment that night, February 1st, guess where he
00:22:43
went? The delivery room, because his wife was in labor with their third baby. So, yeah, he's about to have a new baby
00:22:51
with his wife, and Sandra is telling him she's pregnant, too. Now, maybe he would
00:22:56
have found some way to keep this under wraps, [music] but on January 20th, Matthew found out that Sandra had been
00:23:02
telling people about their affair. Apparently, he had been under the impression that [music] it was like
00:23:07
their little secret, but it was far from it in Sandra's circles. And apparently,
00:23:12
leading up to her death, this friend, who we're going to call Jill, tried to use that to her advantage. Jill said
00:23:19
that her and Sandra got into an argument about some money that Sandra owed her, and Jill told Sandra that if she didn't
00:23:25
start to pay up, she was going to go file a police report, which she did on January 20th, just weeks before Sandra's
00:23:32
death. When Stoughton PD told Jill that this was a civil matter, Jill got upset,
00:23:38
and in her anger, she, over the phone, basically said, well, like, you can tell whatever police officer, detective, that
00:23:44
Sandra's in a sexual relationship with, that he can tell her to pay back the money.
00:23:49
And how did the officer on the phone respond to that? They went straight to Matthew,
00:23:54
and they're like, um, "What's this about?" And according to investigative files, Matthew got really rattled and
00:24:01
told that person, {quote} not to speak about this to anyone, and to never talk about it again. {end quote}
00:24:08
And whoever he told that to must have kept their code of silence, since we know the internal affairs investigation
00:24:14
did not start then. >> Right. But, that day, after Matthew was approached about the affair, he texted
00:24:20
Sandra. "Dude, your [ __ ] friend called my job, Sandra. WTF? You also told me that
00:24:28
no one knew about us, yet she claimed we are fucking." "It's literally nothing."
00:24:33
"It's not nothing. She called my job. That's insane. Like, you have no idea how bad what she did is.
00:24:40
I literally can't believe this is even real life. Like, what else do I have to worry about now? Which other friend will
00:24:46
do something tomorrow?" And what's so weird is after this interaction, Matthew just, out of
00:24:54
nowhere, completely changes his tune [music] and starts to speak really positively to Sandra about their whole
00:25:01
situation. And Sandra actually texted her friend about it. "So, the father came by last night. It
00:25:08
was like a complete 360 change." "180?" "Yeah, lol." "Good or bad?" "Good, but unexpected. [music] So, it kind of threw
00:25:18
me off and made me a little uncomfortable, but that's cuz of how things were going. But, it was like a
00:25:24
complete 180 from where we were at." On this same night, along with having a heart-to-heart, Matthew also asked
00:25:33
Sandra for a key to her apartment and [music] the code to her building's entrance.
00:25:38
But, even with him seemingly doing everything right, like saying the perfect things,
00:25:44
there were moments where Sandra felt uneasy, like something wasn't quite right. The day of that 180-degree change
00:25:51
conversation, on January 24th, Sandra texted a friend about something weird. "Last night, he opened my closet door
00:25:59
for something, and then he went in my bathroom looking at my bathroom. And then, I have a dolly in my living room
00:26:05
that he asked why I had it. It was just really odd. He started looking around. I
00:26:10
don't know. It was really weird." Then, on January 29th, Sandra reminded Matthew what the code to enter her
00:26:17
apartment complex was, and Matthew asked her to confirm that it was a general code for the entire building, not just
00:26:24
like a personal code for Sandra. And that basically brings us to February 1st. >> that Sandra died.
00:26:31
>> Yes. Matthew texted Sandra at around 9:00 p.m. asking if he could come by for
00:26:37
a second. She responded that she would leave her door open for him. And that was the last known message that
00:26:44
Sandra would ever send. I I guess I'm confused right now. Like, MSP had these messages from Sandra's laptop, right?
00:26:53
Like, are they just ignoring them? It's really bizarre. So, listen, hang on. I'm just going to read you exactly what
00:27:03
they say about the laptop messages in the report. >> [music] >> Keep in mind, again, lot of redactions
00:27:07
here. But, it says this. "Over the next several weeks, I analyzed data from Sandra's laptop. In
00:27:15
particular, I was investigating any criminal conduct related to Sandra's death, and something redacted here.
00:27:22
Sandra's laptop gave me access to approximately 12 months of iMessages, social media content, and other
00:27:28
documents/databases. Matt and Sandra had texted thousands of times over the year, as well as
00:27:34
communication with many other friends and family of Sandra. It was clear, based on texts with Matt,
00:27:40
that he and Sandra had a sexual relationship, as he told us in his previous interview.
00:27:45
Then, there's this big redacted chunk, followed by this. All of these conversations were flagged
00:27:50
in the forensics report of her laptop. Sandra communicated often with friends and family. It appeared Sandra had
00:27:57
sexual relationships with other men in the months leading up to her death. There were no threats of harm by any of
00:28:02
these individuals, including Matt. {end quote} That's it? That's literally the last
00:28:08
sentence on the last page of the MSP report that we received. No threats of harm.
00:28:15
So, no criminal culpability. >> [snorts] >> But, clearly, there is a crime here, right?
00:28:22
Well, put possible murder aside. >> Okay. >> Chief McNamara can't look into that,
00:28:28
right? Because that's not her jurisdiction. >> Mhm. But, yeah, the sexual abuse of an
00:28:32
Explorer within the department she now is chief of, move out the way. Like, she is charging full steam ahead. Cuz here's
00:28:41
the thing, along with now being sure that Matthew abused a minor in the program, other witnesses come forward
00:28:49
and say that Sandra told them he wasn't the only one. According to people who knew Sandra, and
00:28:58
I want to preface this by saying much of this information is unconfirmed, but they say that Matthew Farwell wasn't the
00:29:06
only Stoughton Police Department employee who Sandra had a sexual relationship with. She also had one with
00:29:13
William Farwell, [music] Matthew's twin brother. What? When? How? And did did the brothers know about each other's
00:29:23
relationships with Sandra? >> So, William is also an officer with the Stoughton Police Department. They also
00:29:29
met through the Explorers program, because he was a guest instructor. So, when they talked to him, he admits it,
00:29:36
but like, bad case of déjà vu, he says that he had, {quote} been with Sandra sexually maybe two to three times, and
00:29:44
[music] the last of which was sometime in December of 2020. But that was when she was also seeing Matthew. Apparently.
00:29:51
So clearly there is something bigger happening here. So Chief McNamara's agency hires multiple PIs and outside
00:29:59
consultants and over the course of nearly 19 months they go down every rabbit hole you can think of.
00:30:06
And guess what? It didn't even end there. Implicated in the internal affairs investigation was another man
00:30:13
named Robert Devine who was a former deputy chief of the Stoughton Police Department and the officer in charge of
00:30:20
the Explorers program. Robert is actually the man that brought Matthew and his twin brother into the
00:30:25
program as guest instructors. In interviews Robert first claims to have no knowledge of the Farwell brothers
00:30:32
relationships with Sandra, but then he later clarifies that Sandra did bring it up to him as a consenting adult and
00:30:39
Robert didn't believe her. According to Robert, while he and Sandra were never formally in touch, she would often seek
00:30:45
him out while he was on duty offering coffee, hanging around to talk, and showing what he described as an
00:30:51
obsession with police officers. He said this happened about once a week. So, you
00:30:57
know, she's just obsessed with them. What What could they have done? What could they possibly do, Ashley?
00:31:03
>> I It's a gross implication to me that like she was the problem. All because she wanted to be a police officer.
00:31:10
Because she really did love that program. I mean, Sandra joined the Explorers program in 2010 when she was
00:31:16
13 years old and apparently she was drawn to police officers from a very young age. They represented everything
00:31:24
she wanted. Safety, stability, the things that she didn't have growing up. Family members have said that Sandra
00:31:30
deeply respected police, even idolized them. >> [music] >> According to reporting from Boston
00:31:34
Magazine, she joined the Explorers program not only to fulfill her dreams of becoming an officer herself, but also
00:31:41
to find the mentorship and direction that she craved. But instead she was preyed upon. Chief McNamara's
00:31:47
investigation found that Sandra and Robert had been formally in touch and communicating by Facebook Messenger from
00:31:53
2020 up until her death. According to the report, Robert explains this by quote, "Outrageously making claims about
00:32:02
accounts being hacked." End quote. >> In McNamara's investigation, multiple witnesses interviewed also described a
00:32:08
pattern of inappropriate conduct within the Explorer program, including hugging,
00:32:13
kissing, even encounters in a closet involving Robert and the Farwell brothers, as well as comments like,
00:32:20
"Come back and see me after you turn 18." One witness recalls Sandra talking about the stress officers were under and
00:32:26
the way that they looked for outlets. In the end, McNamara recommends that Robert, William, and Matthew all have
00:32:35
their police certifications revoked and be entered into the national decertification index. And there is at
00:32:42
least one other officer from another department found to be complicit as well. I mean, so what now? The men just
00:32:48
get like a slap on the wrist? Well, they actually all resigned before any sort of
00:32:54
action can even be taken. Of course. And in September 2022, Chief McNamara holds
00:33:00
a press conference about her investigation where she publicly addresses >> [music]
00:33:05
>> the entire situation for the first time. What I'm about to brief you on is something deeply troubling
00:33:14
to me as a human being and as a police chief. On February 4th 2021 23-year-old Sandra Birchmore
00:33:28
was found deceased in her apartment in Canton. I'm not here today to talk about the subsequent
00:33:36
investigation into Miss Birchmore's death. Her death was investigated by the Norfolk District Attorney's Office.
00:33:45
What I am here to talk about today is her life and how she was failed by manipulated by
00:33:54
and used by people of authority that she admired and trusted right up until her final days.
00:34:04
Miss Birchmore was a vulnerable person who had one constant in her life since childhood.
00:34:15
Her unwavering admiration of police officers of those serving the military people in uniform
00:34:26
people with oaths and duties to protect and serve. The admiration led her to form relationships
00:34:35
with men who were willing to take advantage of her. The Farwell brothers and Devine
00:34:42
violated their oaths of office and should never have the privilege of serving any community as a police
00:34:53
officer. Through a sustained and deliberate common combination of lies deceit and treachery
00:35:04
they violated the policies and the core values of the Stoughton Police Department.
00:35:11
Not to mention human decency. I stand before you today as a civil servant who is heartbroken
00:35:20
>> [clears throat] >> and incensed by what has transpired and who pledges to this
00:35:31
that this chapter in the Stoughton Police Department and the town of Stoughton is over.
00:35:40
It must never repeat. The revolving door is closed. Chief McNamara turns all her
00:35:49
findings over to the Norfolk DA's office. I assume for prosecution based on her agency's findings of what would
00:35:57
be statutory rape. >> Mhm. But they declined to press any charges. I I'm sorry. What in the
00:36:06
good old boys club is happening here? Well, in a 2022 statement, a spokesperson for the DA says that
00:36:13
statutory rape would be difficult to prove given that Sandra, the main witness, was dead.
00:36:20
O- Okay, but she's dead because he might have killed her. Like this This can't be the
00:36:27
loophole. Yeah, Sandra's family is furious over this. I haven't even spoken much about them yet, but they were
00:36:34
fighting for her every step of the way. I mean, from the second that her aunt was notified on day one about Sandra's
00:36:41
quote unquote suicide, she knew something was up. I mean, not only did she know that Sandra was actually in a
00:36:47
really happy place before her death, but also when her and other relatives went to Sandra's apartment after her death,
00:36:53
the place gave all the signs of someone who did not take their life. When they started going through her things,
00:36:59
everything that they saw made it seem like Sandra's passing was extremely abrupt. There was still wet clothes in
00:37:05
the washing machine and unopened packages, plus more deliveries on the way. She even had cats that she had left
00:37:12
unattended when police finally found her, which made zero sense because she had actually already started making
00:37:18
plans to have somebody look after those same cats while she gave birth, which would have been like seven months later.
00:37:24
But one of the most telling things I think is what her family finds in the bedroom.
00:37:29
They found Sandra's necklace, this keepsake from her grandmother. It was this thin gold chain with like a pink
00:37:36
flamingo charm and it was laying on the floor. The chain had snapped in the middle and then there was this clump of
00:37:43
hair tangled in it. >> to me that feels like a a sign of a struggle. Did police not see it?
00:37:50
Well, apparently the necklace was broken and like hanging off of her neck when they found her, which is documented with
00:37:56
photographs, but it wasn't collected. So, I guess officers didn't think it was relevant. So, when it fell to the floor
00:38:02
as they're I assume like moving her body, they either didn't notice it or like didn't care and collect it.
00:38:07
>> the family show them? Oh yeah, they handed over the necklace to police right away, but that apparently didn't change
00:38:13
anything for them. So, the family members took it upon themselves to galvanize the community on social media
00:38:19
getting people who knew Sandra to come forward and share stories. So many stories that pointed to the Explorer
00:38:26
program and stories that helped build out McNamara's internal investigation. So now to hear that nothing was going to
00:38:33
come of it, like that was infuriating. So, in December of 2022, Sandra's family tries a different approach. They file a
00:38:42
wrongful death suit in Norfolk County Superior Court accusing Matthew, William, and Robert of grooming and
00:38:48
sexually abusing Sandra from a young age and implicating them in her death. The family alleges wrongful death, negligent
00:38:55
supervision, negligent retention, pain and suffering, and emotional distress among other things. And they
00:39:02
specifically mention an ongoing scheme of grooming and misconduct which they say led to Sandra's death. So, that
00:39:09
litigation is still ongoing and a judgment date is set for May of 2026. >> So, Sandra's family members are really
00:39:17
the only ones actually looking into her death as anything other than a suicide. >> So, this is what I was saying. Where you
00:39:26
get this like moment where you're like the system is not working. Everything's broken.
00:39:32
But there are good eggs within it. So, we've got Chief McNamara who has this investigation exposing her officers for
00:39:40
their abhorrent behavior. And then maybe because of her, maybe because of something else like another big case
00:39:50
involving Canton PD and MSP that happens in 2022. >> John O'Keefe. Yeah, maybe because of all
00:39:57
the pressure and the spotlight combined, at some point other good people step in
00:40:03
and say, "Nah-uh, not on our watch." And that's the FBI. Now, it's not really clear how the FBI investigation timeline
00:40:12
unfolded. They haven't been very public about that. >> known to be very public >> [laughter]
00:40:17
>> about anything. But on August 28th, 2024, Special Agent Shanique Castrida releases a 45-page
00:40:25
affidavit with all of her findings. And it details exactly what they think happened and why.
00:40:34
Agent Castrida confirms what we already know about Matthew grooming Sandra when she was a child and lays out Matthew's
00:40:42
motive for murder in clear terms. She writes that in October of 2020, when Sandra heard about Matthew's wife's
00:40:48
pregnancy, she went to him with an ultimatum. She wouldn't expose their years-long sexual relationship,
00:40:54
including the fact that it began when she was underage and that they'd been meeting while Matthew was on duty if he
00:41:01
agreed to try and get her pregnant. Their texts even show Sandra sending Matthew her ovulation schedule. And the
00:41:07
two of them planning sexual encounters around it. But when Sandra got pregnant, she started telling people about it. And
00:41:15
that wasn't part of the deal. The affidavit actually puts forward that on January 20th, when that friend Jill
00:41:20
called Stoughton PD and spilled the beans about Matthew and Sandra, causing that officer to question Matthew, that
00:41:27
is the very moment that Matthew hatched a plan to kill her. And all those heart-to-hearts after that
00:41:34
Agent Castrida says were, quote, "His attempt to appease Birchmore until he could kill her." End quote. And they
00:41:42
have physical proof, they say. The FBI analyzed the data from the health app on Sandra's iPhone. Her last movements were
00:41:51
recorded at 9:40 p.m. That is 3 minutes before Matthew was seen leaving her building. So, it's likely this data
00:42:00
shows exactly when Sandra died and Matthew was still inside the apartment. And when he left, he could have used the
00:42:08
key that [music] he had to lock up behind him. >> Right. And Agent Castrida backs this up
00:42:14
by tapping expert forensic physician Dr. William Smock. He specializes in asphyxiation cases and testified in the
00:42:20
Derek Chauvin trial about George Floyd's murder. According to the affidavit, Smock's findings directly contradict
00:42:27
what state police concluded. He pointed out that the fracture in Sandra's hyoid bone, which is at the top of the neck,
00:42:35
didn't line up with the position that she was found in. Smock explained that when someone is found seated, it is
00:42:41
considered an incomplete hanging, meaning that only part of the body's weight is actually pulling on the neck.
00:42:47
And in his deep dive through forensic research, he could not find a single documented case of a woman fracturing
00:42:53
her hyoid bone in that kind of scenario. Instead, those fractures overwhelmingly
00:42:59
show up in cases of manual strangulation or when the full weight of the body is suspended. So, he concludes with, quote,
00:43:06
"A reasonable degree of medical and scientific certainty that the cause of Ms. Birchmore's death is asphyxia and
00:43:13
that the manner of her death is homicide." End quote. And something else really interesting that Agent Castrida
00:43:20
writes is that after Matthew consented to handing his personal cell phone over to state police, he used his work phone
00:43:28
to search and then immediately delete searches for >> Right, right. >> whether deleted iMessages can be
00:43:35
recovered and whether someone can revoke consent in Massachusetts. [music] And it's on the last page of this
00:43:41
document that Agent Castrida writes this. Quote, "The information set forth above supports the government's motion
00:43:49
to detain Matthew Farwell pending trial in [music] this case." And that is how on the very date Agent
00:43:57
Castrida files her report, Matthew Farwell is arrested. So, how did the FBI get jurisdiction of the case in order to
00:44:06
make the arrest? Like, do they just like Trump state agencies by default? >> No, the FBI makes an ingenious move to
00:44:13
charge Matthew with one count of killing a witness or [music] victim, which is a
00:44:18
federal crime charge that often appears in connection with other federal charges, like sometimes in mob cases or
00:44:25
crime rings that span like multiple states. >> But in this case, it allowed the FBI to
00:44:30
step in without involving MSP. >> Exactly. And this charge also happens to be punishable by death. [music] So, that
00:44:38
same day, Matthew pleads not guilty at an arraignment. And as of this recording, Matthew has been indicted by
00:44:45
a federal grand jury and his trial is currently scheduled to begin on October 5th, 2026.
00:44:52
Until then, he's being held without bail at a detention facility in Rhode Island.
00:44:56
And our reporter, Nicole Kegan, actually reached out to his attorney for comment,
00:45:00
but as of this recording, we have not heard anything back. There is news still breaking in this case, though. The
00:45:06
strangest thing to me was broken by the Boston Globe earlier this year. They wrote that people familiar with the
00:45:13
investigation who spoke on the condition of anonymity said that DNA testing showed Matthew was not the biological
00:45:22
father of Sandra's unborn baby. Okay, first of all, who are these sources? I like need to know.
00:45:29
>> but I have no idea. >> And secondly, the motive still makes sense for me, though, cuz if Matthew
00:45:34
thought he was the father, which it really seems like he did from the text messages, like that's
00:45:40
your motive. And also, he refused to give his DNA at first, right? >> Well, also, he had a twin brother who
00:45:47
admitted to sleeping with Sandra at the same time. And like my own PSA, I no longer trust adult twins who work at the
00:45:55
same place if that place gives them access to children. I know that sounds specific, but I just listened to the
00:46:00
newest season of Dig and like oh hell no, there is a pattern here. But there is also another pattern that I found,
00:46:08
one with the Explorers program. Sandra's story is one that did get a decent amount of attention [music] and
00:46:15
had been kind of like living in the back of my brain since 2022-ish when I first
00:46:20
heard about it. And in digging into that, this local article from here in Indianapolis popped up and grabbed my
00:46:28
attention. It was from April 14th, 2022. It said, "IMPD officer tied to teen suicide ordered to write weekly journal
00:46:37
in rare sentence." And that's kind of like Crime Junkie clickbait. And when I began reading, I had this
00:46:45
weird déjà vu. Deleted text messages, the police Explorers [music] program. So, I began to wonder, maybe
00:46:52
William and Matthew and Robert weren't a couple of bad apples in the system. What
00:46:58
if the program is designed in a way that actually attracts predators and puts children at risk? Like, parents are
00:47:06
sending their kids off to work with the police because like you couldn't be safer, right? Wrong. The more I looked,
00:47:15
the more I found. And our reporter, Nina and I, have spent months, the better part of a year, uncovering systematic
00:47:23
issues with the Explorers program. And next week, we are going to be releasing an entire episode with every twisted
00:47:31
detail we found. [music] So, for those of you who don't want to wait, you can actually listen to that
00:47:36
episode right now in our fan club app. I think everyone needs to know about it. But it is truly required listening for
00:47:43
anyone considering the program or for any parent who has a kid in it. Like this is something that we can't just
00:47:49
look away from and like hope stuff that stops happening. We have to shine a light directly on it. So, tell everyone
00:47:55
you know, next week's episode of Crime Junkie is required listening for everyone so you know what is there and
00:48:02
how you can keep your kids and your friends safe. You can find all of our source material for this episode on our
