[AUDIO LOGO] NARRATOR: This time on "Killers Caught on Camera." In the US, in Colorado, a couple are found
00:00:15
shot dead in their own garage. KRISTEN DONOHO: To put them out of their misery, he decided to unload his entire magazine
00:00:22
into both of their bodies. MATT TALMON: It was a horrific, bloody, terribly violent scene.
00:00:31
BRYAN GRAY: I just remember feeling helpless because there's nothing you can do.
00:00:35
NARRATOR: And in the UK, a long running feud at work ends in a lethal altercation.
00:00:43
FRANCIS FITZGIBBON KC: Willis made another threat to kill Mr. Darn. MICHAEL DARN: The knife actually pierced his aorta
00:00:51
and he died from catastrophic internal bleeding. [THEME MUSIC] MAN 1: It just sounds like something
00:00:57
bad is happening to her. WOMAN: We know what happened because the video tells us what happened.
00:01:01
MAN 2: I heard twp gunshots. OFFICER: Drop it. Whatever it is, drop it. MAN 3: That does not prove that I killed my wife.
00:01:09
MAN 4: The camera doesn't lie. NARRATOR: Colorado. Between Denver and Colorado Springs in Douglas County
00:01:21
is Franktown. MATT TALMON: It is extraordinarily low crime. It's historically one of the fastest,
00:01:29
if not the fastest growing county in the United States. In the North, it's very suburban,
00:01:35
but in the South county it's very rural. KRISTEN DONOHO: Franktown is a quiet area,
00:01:41
very family oriented. NARRATOR: It was home to 34-year-old Todd Gray. LONNA GRAY: Todd was charming.
00:01:49
He was funny, independent, never had trouble making friends. He was very outgoing.
00:01:55
His laugh was contagious. He would laugh a lot. You always knew he was in the room when he was there.
00:02:03
NARRATOR: He had four siblings. Todd was the middle child. BRYAN GRAY: He wasn't an inside child.
00:02:11
He was outdoors all the time. They went out and either did horses or dirt bikes or chores or whatever.
00:02:20
But he was always the most playful one, always wanted to play. NARRATOR: From an early age, Todd
00:02:26
was keen to follow in his father's footsteps as a mechanic. BRYAN GRAY: Before he had his license,
00:02:31
he was buying and selling cars. He'd buy something and fix it up a little bit and sell it when he's 15.
00:02:36
He was a fantastic welder. He could weld anything. He pretty much taught himself how to do it.
00:02:42
NARRATOR: Todd and his dad spent a lot of time together fixing up cars. - Todd was 12 when we did this car.
00:02:50
We just enjoyed doing this. We spent a lot of time out here. He had to know how to do everything.
00:02:55
If there was a way to do it, he wanted to figure out how to do it. NARRATOR: Todd married his high school sweetheart,
00:03:01
and together they had a child. - She was the light of his life. BRYAN GRAY: It calmed Todd down to have his daughter.
00:03:09
It was a huge focus for him. NARRATOR: But Todd struggled with addiction. LONNA GRAY: Right out of high school,
00:03:15
Todd was having some issues with alcohol. That's probably why his first marriage didn't work out.
00:03:20
And then his health was going downhill. His liver started failing already at a very young age.
00:03:27
He knew he had to do something, so he actually showed up one day and told his dad, you need to keep me busy.
00:03:33
NARRATOR: Todd and his first wife divorced and he was sober for eight years. He started a new relationship, and
00:03:40
in 2016 they had a daughter, a second child for Todd. In 2019, the Gray family took on a new employee,
00:03:51
Jessica Mitchell, a single mother with a love for animals and the outdoors. - Jessica came to work for us for a couple of years,
00:04:03
always on time. LONNA GRAY: She talked about her kids all the time. Jessica had a smile that just lit up the room.
00:04:11
She was bubbly. NARRATOR: But everything changed when Jessica and Todd started dating.
00:04:18
BRYAN GRAY: Jessica would be more of a party person, drink, have fun, Todd couldn't drink.
00:04:24
Right there we could just tell that, not a good match because once he'd start, he wouldn't stop.
00:04:31
And it wasn't long for the drinking and partying kind of got out of hand. LONNA GRAY: It went downhill fast.
00:04:39
They thought that Bryan and I were controlling them. Once we had to ask them to leave the home they were living
00:04:47
in, we really didn't have much contact with Jessica or Todd at all. But it was definitely the drugs that tore us apart.
00:04:55
BRYAN GRAY: It was kind of heartbreaking, you got to kick your child out of the home
00:04:59
that we built together, but it had to be done. LONNA GRAY: To be honest, him and I had a pretty bad
00:05:05
falling out. He lost custody of his kids. NARRATOR: Jessica also lost custody of her children
00:05:13
and had a difficult relationship with her parents and two younger brothers. But by 2022, Todd was getting his life back together.
00:05:23
He'd started his own business, fixing cars. BRYAN GRAY: He was building some momentum,
00:05:30
getting his little business going, so I was proud of that. NARRATOR: In January 2022, Bryan met Todd in the car shop
00:05:38
in town. BRYAN GRAY: We just sat and talked for probably half an hour and then just it's like, OK,
00:05:46
I gotta go, so he left. And, I mean, you never know that's the last time you're ever going to talk to him but that was it.
00:05:54
NARRATOR: Early afternoon on Tuesday, February 8, 2022, 911 dispatchers received an alarming call.
00:06:19
Investigators arrived at a remote property South of Franktown. MATT TALMON: When I went inside,
00:06:27
I saw an adult female and an adult male lying deceased on the ground of the shop.
00:06:32
It was a horrific, bloody, just terribly violent scene. NARRATOR: A dog had also been shot.
00:06:41
KRISTEN DONOHO: Whoever did this has no regard for life, leaves two people dead and doesn't call for help.
00:06:48
And so our initial thoughts is we need to get this person into custody as soon as we can.
00:06:52
They're very dangerous. NARRATOR: Police obtained a search warrant for the property.
00:06:57
They started to look for any evidence to lead them to a suspect. MATT TALMON: We discovered in part, bloody thumbprint or
00:07:04
fingerprint within close proximity to the bodies on one of the vehicles. We discovered inside the home that it had been ransacked.
00:07:15
NARRATOR: The bodies in the garage were confirmed to be Todd Gray and Jessica Mitchell.
00:07:21
- Todd, I believe, had suffered at least one wound to the head that was fatal. Jessica Mitchell had certainly suffered gunshot wounds
00:07:28
to her abdomen, chest, torso. NARRATOR: News of Todd and Jessica's death spread amongst family and friends.
00:07:39
BRYAN GRAY: I just remember it being very emotional and feeling helpless because there's
00:07:45
nothing you can do at all. And it's like, what did he get himself into? - I was shocked when he told me it was Todd and Jessica.
00:07:58
I said, Todd and Jessica? And he's like, yes. NARRATOR: Just three hours after obtaining
00:08:11
the search warrant, police got a major break in the case. Exterior cameras on Todd and Jessica's property
00:08:20
showed a vehicle arriving at 12:51 AM on Tuesday, February 8. MATT TALMON: On the video we captured, at that time,
00:08:31
an unknown suspect arriving at Jessica and Todd's residence in a flatbed Ford pickup.
00:08:37
The video didn't capture the plate, but it was a very distinct vehicle. NARRATOR: The driver headed into the garage.
00:08:45
Todd was already inside. Moments later, Jessica was captured on camera leaving the house and appeared to hesitate.
00:09:04
MATT TALMON: At this point in the video, we can see Jessica Mitchell and our unknown suspect
00:09:10
exit the garage together. There doesn't appear to be any sort of animosity. And from the video, we believe, at that time,
00:09:19
that they were known to one another. We see that Jessica is not under any kind of distress
00:09:27
when she returns to the garage. This is the last time we see Jessica Mitchell alive.
00:09:31
NARRATOR: Just over a minute later, what appeared to be a friendly visit would prove
00:09:36
fatal for Todd and Jessica. MATT TALMON: And at this point we can clearly see that he's armed with a shotgun
00:09:42
and that he enters the garage with a shotgun. NARRATOR: Over the next few minutes,
00:09:48
the unidentified man returned to his truck multiple times to get more guns. MATT TALMON: We can see that the male
00:09:56
is also armed with a handgun. NARRATOR: Investigators concluded that Jessica and Todd had been shot and
00:10:03
killed during this time frame. 16 minutes later, the man was still on the scene.
00:10:12
He went inside the house for over half an hour. MATT TALMON: We see the male turn off the rear porch light
00:10:18
and he exits the residence. He's carrying a duffel bag and another shotgun that he's removed from the house.
00:10:27
We know that he's armed and dangerous. NARRATOR: The unknown man then roamed around the property
00:10:33
for another 25 minutes. JULIA SHAW: Staying on scene for such a long time after the killings, to me, suggests
00:10:41
that he didn't have a real plan as to what he was going to do next. He, obviously, went and got his guns,
00:10:48
and so he had a plan to kill them at least in that moment, but then afterwards, usually what
00:10:52
you do is you'd start covering up the crime scene or you'd leave and you'd make an escape.
00:10:56
But in this case, the fact that he's just roaming around almost feels like he's still processing
00:11:00
what he's going to do now. NARRATOR: After almost two hours on the property, the unidentified man leaves, hitting a car and
00:11:09
then a dumpster as he exits. KRISTEN DONOHO: He pulls out and then he goes South,
00:11:15
and that's the last we see on camera. NARRATOR: The footage gave the police a clear image of the prime suspect,
00:11:21
but he was unknown and at large. KRISTEN DONOHO: It's a white male, bigger, stockier build,
00:11:27
and his hair is very, very distinct. We need to find this guy and we need to find out who he is.
00:11:34
NARRATOR: The police decided to release the image of the man to the public, and got a lucky break
00:11:40
when a woman recognized him. The name she gave was Casey Devol. - We pull his dossier photo from his driver's license,
00:11:50
compare it to the surveillance footage, it's identical. NATE MARSH: Casey Devol worked for the town of Castle Rock,
00:11:56
which is in Douglas County. But what's most important here is he's the brother of Jessica Mitchell.
00:12:02
What we're looking at is potentially a brother killing a sister. It's especially heinous.
00:12:06
It's especially grave. We don't know if any other family members are potentially
00:12:10
at danger, this is a axe to grind or a grudge that was against his sister. We don't know if this is a grudge against Todd
00:12:17
and potentially his family. - Siblicide is when somebody kills a sibling. And it's one of the most rare forms of murder.
00:12:27
When you hear the term siblicide or when you hear about someone who's killed a sibling,
00:12:30
your mind jumps to kids. But, actually, siblicide is almost always committed after the age of 25.
00:12:39
There's a couple of theories as to why actually the rate goes up with age. And one of the theories is that there's more access to guns,
00:12:46
and the other is that resentments that maybe started when you were in your teenage years,
00:12:50
they build up and they build up and they build up. And you've basically got this festering
00:12:55
of wounds, psychological wounds, over time that ends with siblicide, with the worst
00:13:01
possible outcome. BRYAN GRAY: So the first thing that came to my mind is like, who would kill their own sister?
00:13:08
LONNA GRAY: When we learned that Casey was the prime suspect and they posted his picture
00:13:12
and we're looking for him, it's like, OK, we have a suspect. Let's find him. NARRATOR: The hunt was on for Casey Devol.
00:13:21
KRISTEN DONOHO: Within Douglas County, we have a system called Flock. Flock is a license plate recognition
00:13:28
system that captures pictures of license plates. We did a workup on Casey, and we discovered
00:13:34
that he had a green F250 Ford truck registered to him, and we put his license plate information
00:13:41
into our Flock system. And comparing those Flock images to the surveillance footage, it was an exact match.
00:13:48
At this point we have enough to obtain an arrest warrant for Casey Devol. NARRATOR: Investigators went to Casey's property
00:13:55
in Douglas County. KRISTEN DONOHO: One of our impact detectives, he puts a drone up over Casey's house,
00:14:01
and he does see that Casey's truck is there. We immediately author a search warrant for Casey's home.
00:14:07
I find out that Casey ended up taking his father's gold Ford truck and he left his green truck at the property
00:14:14
and he was not home. Casey is in the wind, Casey is on the run. REPORTER: We start with breaking news tonight.
00:14:22
If you live in Douglas County, deputies want you to be on the lookout for a man considered dangerous.
00:14:27
This man here. NARRATOR: Police spoke with Casey's family and friends for any information about his whereabouts.
00:14:34
KRISTEN DONOHO: We knew he was communicating with his mom and his really good friend via text message on his personal phone.
00:14:41
He told family via text message and one of his good friends that he was fleeing to Nebraska.
00:14:48
NARRATOR: While he was on the run, Casey recorded an unapologetic video. Police gained access to Casey Devol's phone data.
00:15:22
They discovered that he'd driven 400 miles from the crime scene to Salina in Kansas.
00:15:32
Salina police officers immediately tracked him down. Detectives Matt Talmon and Kristen Donoho
00:16:08
drove through the night to Kansas so they could interview Casey KRISTEN DONOHO: He's very cordial.
00:16:25
He's very friendly in-person. He's very affable. You would never think that he just committed a murder.
00:16:54
And he says at some point he receives this gift from Jessica. And he says it's this wooden crossbow
00:17:01
that has an inscription in it. He says they have this argument, he basically calls him a liar.
00:18:03
He said to put them out of their misery, he decided to unload his entire magazine
00:18:07
into both of their bodies. And he said the dog caught a stray round. NARRATOR: Casey Devol agreed to waive extradition.
00:18:20
The detectives drove him back to Colorado. On Thursday, February 10, autopsies were performed on Todd Gray and Jessica Mitchell.
00:18:31
- Todd Gray had sustained seven gunshot wounds in total. One to the head, several were from a shotgun
00:18:38
and some were from nine millimeter caliber. Jessica Mitchell also sustained multiple gunshot wounds,
00:18:45
one being fatal through her heart and lung. The coroner has deemed both deaths as homicide.
00:18:52
NARRATOR: The autopsies revealed how Jessica and Todd had died, but a critical piece of evidence
00:19:00
was recovered during Jessica's autopsy which would break the case wide open. - Jessica had hidden in her bra a digital audio recorder.
00:19:10
It was an outstanding piece of evidence because it fills the gap what the video footage was
00:19:16
unable to capture, namely what actually happened in the garage leading up to and during the homicide.
00:19:30
- She put a recording device into her bra, and that raises a lot of red flags. Why would you put a recording device in your bra?
00:19:40
That's not where it normally lives. That's not a place that people just casually keep them, right?
00:19:43
And so you have to go out of your way to put it there. And you're doing that because you
00:19:48
want to record a situation that you think might escalate, or where there might be some conflict that you need
00:19:53
to have evidence of later. And now that evidence might be to hold it against the person themselves, to say, you said this
00:19:58
and to make them somehow pay for whatever they said, or it could be gathering evidence because you're
00:20:05
afraid of somebody. So the question in my head the whole time is, given how casual
00:20:10
she sounds, is she actually masking that she's afraid because she put this recording
00:20:16
device in her bra? LONNA GRAY: We know that she knew her brother was coming over.
00:20:20
We knew that there was some animosity between her and her family. The only thing I can think of is
00:20:25
that she was just wanting to record everything so that nothing was thrown in her face later.
00:20:32
MATT TALMON: What we hear in the audio is a very cordial, friendly conversation between Todd, Jessica and Casey.
00:20:39
At no time are we going to hear any kind of argument. KRISTEN DONOHO: I'm listening to the recording,
00:21:02
there is a mention of a crossbow but there's nothing mentioning the inscription on it.
00:21:07
That's never talked about. MATT TALMON: The conversation is jovial, happy. They're joking.
00:21:18
However, Jessica doesn't realize this, this is the last time she'll speak with her brother Casey
00:21:23
before he murders her. NARRATOR: Just one minute later, Casey pulled a shotgun on his sister and Todd.
00:21:31
The audio is extremely distressing. JULIA SHAW: Casey walks into the garage and immediately starts to shoot.
00:21:39
[GUN SHOT] You can hear 10 or 15 seconds of just screaming. It's chaos. And there's so many gunshots.
00:21:50
And you hear her screaming, you hear him screaming, you hear the dog barking. And it's harrowing to hear the actual last moments
00:21:58
of their life. And at some point it just goes quiet. It's a shocking escalation from the cordial, friendly banter
00:22:08
that we had just moments ago. From the situation alone, you wouldn't be able to POINT at a moment and say,
00:22:15
this is where it all went wrong. This is where it escalated. KRISTEN DONOHO: Casey is now in this room with them
00:22:31
and is mocking them. And he's just making some very just derogatory statements towards them, just being very disrespectful towards them now
00:22:41
that they have died. Also in this recording, the dog is still alive. [DOG BARKING]
00:22:49
JULIA SHAW: The weird comments he makes at them, at the dead bodies, and says in this mocking tone suggests
00:22:56
someone who has finally won and is now able to enjoy their victory. And I think him walking around the property for a while
00:23:06
and not leaving, not immediately trying to get out of there points to me to someone
00:23:10
who went through the motions of something that maybe he'd thought about for a while
00:23:14
and then enjoyed the moment. NARRATOR: Crucially, the audio recording completely contradicted Casey's interview testimony.
00:23:26
KRISTEN DONOHO: Todd never threatened him with a gun, there was nothing. It was a straight up ambush.
00:23:31
NARRATOR: Detectives Kristen Donaho and Matt Talmon confronted Casey Devol with the new evidence.
00:24:40
JULIA SHAW: This is one of the most interesting interviews I've seen in a long time.
00:24:43
The fact that he says that he believes that there was a heated argument, even though at this point he knows that that's not true,
00:24:50
and then he says, well, maybe it's because I fabricated it in my own mind, and so what he's saying is that he has a false memory
00:24:57
of what happened. And even when confronted with the evidence, he still feels like this argument
00:25:02
happened because he's been playing it in his mind so many times. NARRATOR: The night before the murders, Casey
00:25:09
had been hanging out with a female friend. She told the police that Casey said he
00:25:14
was going to collect a debt. And the next morning, he texted her. But the police still wanted to understand
00:25:42
why Casey shot and killed Todd Gray and his own sister, Jessica Mitchell. JULIA SHAW: What we know is that he had conflicts
00:26:29
with his sister for many years, since he was a child, and the family also considered her
00:26:34
the black sheep of the family. She had all these substance use problems, there were neglect issues with her own children,
00:26:39
so there was a lot of beef going back years with his sister. So the question, of course, is why did he kill Todd?
00:26:47
Why did he kill his sister's partner? And it seems to me that the answer might be a really sad one, which
00:26:55
is that simply he was there. And that he probably wasn't specifically a target, he was effectively collateral damage to this murder
00:27:05
that he'd been fantasizing about. It's possible that he saw them as a pair and that he always sort of thought,
00:27:11
if I'm going to kill my sister, I'm also going to kill her partner, but I think it's more likely
00:27:15
that he was there that night. And if he hadn't been there, he might still be alive.
00:27:21
NARRATOR: Casey Devol was charged with two counts of first degree murder and animal cruelty.
00:27:27
Originally he pleaded not guilty, but later he decided to change his plea. NATE MARSH: The plea that he ultimately
00:27:35
took, he pled guilty to two counts of murder and the second degree as well as that animal cruelty.
00:27:41
And received a sentence just shy of 100 years. NARRATOR: The case divided the community.
00:27:49
NATE MARSH: There were certainly people that said there was no way that Devol could have done
00:27:53
this, and that's why it was so important at the sentencing to make sure that we played just
00:27:57
a portion of that audio recording so that we could set the record straight for any community
00:28:01
member that wanted to know. This recording doesn't lie. BRYAN GRAY: I just thought, what a coward.
00:28:06
He just walked up and shot them. Nobody had a chance there but him. He had the guns, there was no fair fight,
00:28:13
there was no nothing. He just lost it. NARRATOR: The audio recording was vital to bringing
00:28:18
Casey Devol to justice. NATE MARSH: Jessica's final act was really the instrumental and key piece of evidence
00:28:26
that put her murderer behind bars for the next 100 years. It was in that moment that she practically
00:28:32
solved her own murder. LONNA GRAY: I think they could have together got their life under control.
00:28:38
They both would have been very happy and they would have impacted a lot of people.
00:28:42
BRYAN GRAY: He had a really good heart. I think he could have done really well in life once he
00:28:46
figured out his struggles. I'm still proud of what he accomplished. He was just a person that I could talk to all the time.
00:28:54
He was my son, but he was also a good friend. [AUDIO LOGO] NARRATOR: The murder of a sibling is known as siblicide,
00:29:08
and it is an incredibly rare occurrence. JULIA SHAW: In the US, about 150 people every year
00:29:15
kill a sibling. And when it happens, it's usually an accumulation of fights and arguments
00:29:19
and slights over a long period of time, but within the family. Long standing grudges don't just fester inside the home,
00:29:27
they can also fester in other contexts. For example, in settings where trivial issues, perceived
00:29:33
slights, and verbal threats become physical manifestations and can turn into violence.
00:29:39
NARRATOR: In 2024, a combination of these three factors led to a brutal murder. [AUDIO LOGO]
00:29:53
In the UK, eight miles Northeast of Newcastle Upon Tyne is the town of North Shields.
00:30:01
AMBER HAQUE: North Shields sits on the North bed of the River Tyne. North Shields has a really interesting history.
00:30:08
It was a real epicenter for the fishing industry and for the shipbuilding industry as well.
00:30:14
NARRATOR: It was home to 35-year-old Andrew Darn. MICHAEL DARN: Andrew was larger than life.
00:30:21
He looked very intimidating because of the size of him, but he was as soft as anything.
00:30:28
He would do anything for anybody. NARRATOR: Andrew grew up 200 miles South in Northamptonshire.
00:30:35
He had an older brother and a younger sister named Natalie. - Andrew was funny. He was always making everyone laugh.
00:30:44
You couldn't help but laugh at him, no matter what you did. [LAUGHS] You are watching the same video over and over.
00:30:55
NARRATOR: As a teenager, Andrew fell in love with fishing. MICHAEL DARN: Andrew used to like cod fishing.
00:31:02
I think it was because it was peaceful and relaxing for him, and he could sit and concentrate.
00:31:09
It's the only time he ever had any patience. NARRATOR: When Andrew was 17, the family
00:31:15
moved to the Northeast and Andrew started working with his dad. - He used to be the boss at work.
00:31:21
He used to tell me what to do and I used to do it. At the end of the day, roles were reversed, I was the dad
00:31:30
and he was the son. And that's how we got on so well. NARRATOR: But the job meant Andrew spent a lot of time
00:31:37
away from home, and it started to take its toll. MICHAEL DARN: He turned and he said,
00:31:42
look, it's getting too much, dad. The children are missing us. They don't want me to go away on a Sunday.
00:31:48
He said, so I'm going to have to get a job at home. I says, fine. If that's what you've got to do,
00:31:53
then that's what you've got to do. NARRATOR: In spring 2022, Andrew started working at a garage door fitting
00:32:01
company on the Tyne tunnel industrial estate in North shields. MICHAEL DARN: He went up on the Monday
00:32:09
and he never looked back. He loved the job. NARRATOR: But Andrew's boss had been
00:32:13
involved in a long running feud with a man named Alder Willis. FRANCIS FITZGIBBON KC: Mr. Willis ran the business
00:32:22
next door to where Andrew worked, which was a cafe deli business, which he'd been running with his partner
00:32:30
for many years. Andrew had walked into a long standing antagonism between the two neighboring businesses, which
00:32:40
had started years before he ever began working there, in about 2010, over a parking dispute about who
00:32:49
was entitled to park in the parking spots outside the businesses. ROBERTA BABB: A debate about a parking space on the surface
00:32:57
feels like a trivial matter, but, really, parking spaces are symbolic. They're symbolic of territory.
00:33:04
So what looks like a surface disagreement actually if we look deeper, is about space,
00:33:10
it's about territory, it's about respect, it's about power and control. And they have to defend not only their parking space,
00:33:17
but their honor at all costs. NARRATOR: And the defense of honor spiraled out of control.
00:33:23
FRANCIS FITZGIBBON KC: Over the years, there had been a series of microaggressions,
00:33:28
quite trivial incidents where they were winding each other up. But it came to a bit of a head in 2021.
00:33:34
NARRATOR: Mr. Willis assaulted Andrew's boss. He punched him and knocked him over.
00:33:40
FRANCIS FITZGIBBON KC: It didn't go to court but he was given a caution by the police.
00:33:45
- Long running feuds are really an interesting concept. They're not necessarily common in the general population,
00:33:52
but they do occur frequently in specific contexts or instances where there tends to be interpersonal
00:33:59
or community tensions. And these tensions kind of bubble up. The initial grievance gets escalated because each party
00:34:06
retaliates against the other. Ultimately, this culminates in what's known as a cycle of revenge, which
00:34:12
is difficult for either party to exit because each party wants to maintain and hold
00:34:17
on to the winning position. NARRATOR: Alder Willis was cautioned by the police for assaulting Andrew's boss, but
00:34:25
the antagonism between the two businesses continued, and Andrew seemed to become the focus
00:34:31
of Alder Willis's aggression. - It was completely unclear why he became a target.
00:34:38
It seems that he just took a dislike to him. NARRATOR: Andrew's boss started keeping
00:34:43
a record of any incidents of conflict with Alder Willis. In October 2022, it was recorded that Willis
00:34:51
had threatened to stab Andrew. AMBER HAQUE: On a number of occasions, Willis would threaten to have Andrew stabbed.
00:35:01
He would be constantly giving him dirty looks and making these threats that he would get someone
00:35:06
to come and stab him, which obviously are quite terrifying threats. NARRATOR: March 26, 2024, there was another incident involving
00:35:16
the female partners of the warring businesses, but, once again, Andrew became the target.
00:35:23
FRANCIS FITZGIBBON KC: That was the point at which Willis made another threat to kill Mr. Darn.
00:35:29
NARRATOR: But Willis's threatening behavior didn't end there. - 20 minutes after the incident,
00:35:36
Andrew leaves work to run a few errands, but he isn't alone. Willis tails Andrew for a few minutes, at this point,
00:35:44
Andrew notices him and pulls over onto the curb. - He was clearly very anxious about what was going on.
00:36:03
He got out of the car and shouted something in Willis's direction. After, Andrew went home and he was anxious.
00:36:15
MICHAEL DARN: He'd spoke to myself and the wife on the phone. He sounded very worried.
00:36:22
I think he wasn't so much worried for himself, if he was worried for his partner and
00:36:28
the children. ROBERTA BABB: Stalking involves repeated unwanted attention, harassment or contact, or any sort of behavior
00:36:39
which aims to intimidate someone and provoke feelings of anxiety and fear. And it can include behaviors such as following.
00:36:47
If you look at what Alder Willis did, he decided to follow Andrew down in his vehicle.
00:36:52
When a person is a victim of stalking, it's incredibly unsettling. It's distressing.
00:36:58
There's a sense that your space has been intruded upon in a way that feels incredibly threatening.
00:37:04
NARRATOR: The next morning, March 27, 2024, Andrew set off for work as usual. Less than an hour later, paramedics
00:37:15
were called to the Tyne tunnel industrial estate and found a man with severe injuries.
00:37:23
They tried to save him, but the man was pronounced dead at the scene. He was confirmed to be Andrew Darn.
00:37:33
Police went to Andrew's parents' house to tell them what had happened. MICHAEL DARN: They said that Andrew had been killed.
00:37:41
Just couldn't believe it. You go numb. You don't comprehend what's happened. You think it's a dream.
00:37:50
It just doesn't hit home. NATALIE DARN: I had entered the front door of my mom and
00:37:55
dad's house, and mom just stood and told us that Andrew had been murdered. And I just dropped to the floor.
00:38:02
I was like, no, he's not. He's not. NARRATOR: Police searched the area for surveillance footage
00:38:14
and found a crucial camera inside the garage door company. - We're seeing on the main screen
00:38:23
the view directly from the front of the office. NARRATOR: As the police tracked back through the footage,
00:38:30
they were able to piece together the events of that morning. At 7:55 AM, Andrew Darn pulled into the parking area outside
00:38:40
the garage door company. - This car here is Andrew Darn's car parked on the right hand side of the parking area.
00:38:51
And up here we see Alder Willis's van. You see the back doors of the van are open because he is in the process
00:38:59
of unloading boxes with his supplies for the cafe that day. NARRATOR: Andrew's dash cam recorded what he said to Alder.
00:39:16
At 7:59 AM, Andrew got out of his car. FRANCIS FITZGIBBON KC: Well, this is the beginnings
00:39:23
of a conversation, certainly. And it looks as though Andrew is quite animated. He's gesturing quite a lot.
00:39:34
The important thing to notice, as far as Willis is concerned, is where his hands are.
00:39:39
His left hand is out and gesturing, but his right hand stays firmly stuck in his pocket.
00:39:46
Andrew Darn then throws a punch at Willis. Willis reacts by taking his right hand out of his pocket
00:40:00
and he strikes two blows towards Andrew's torso. NARRATOR: After the altercation,
00:40:09
Andrew walked back to his car. FRANCIS FITZGIBBON KC: Andrew appears to be walking quite normally.
00:40:15
He is walking to his car, turning away from any additional violence. NARRATOR: Andrew then remained inside the parked vehicle.
00:40:24
- We see Willis heading back towards his business. He goes in for a bit, he comes out.
00:40:31
You can see him looking in the direction of Andrew's car, and you can see him moving his hand
00:40:37
across his throat, which we took to be a very hostile gesture. This is about 20 minutes after their confrontation.
00:40:46
And Willis goes over to Andrew Darn's car-- he may have thought there was something amiss--
00:40:53
and he reaches into the open driver's door window. Can't quite see what he's doing, but he's peering in
00:40:58
and possibly shaking or trying to rouse Andrew at that point. And then he walks away again.
00:41:05
NARRATOR: Alder Willis went back to his shop. Then 30 seconds later he returned again to Andrew's car.
00:41:14
FRANCIS FITZGIBBON KC: He opens the door this time and he, again, he seems to be looking or reaching inside.
00:41:20
Whatever he has seen, Alder Willis does not call for help. You can see how shocked his partner looks because she
00:41:30
puts her hand across her face. Alder Willis walks away from Andrew's car, gets into his van
00:41:36
and drives off. NARRATOR: Andrew remained in his car for a further three minutes before his boss's partner found him severely
00:41:49
injured and unconscious. Five minutes later, emergency services arrived on the scene
00:42:05
and attended to Andrew. Six miles away at his home in Camperdown, Alder Willis was recorded on a doorbell camera.
00:42:24
- It shows him having just reached his street, speaking to his partner who has traveled
00:42:31
separately from the cafe. He says, and I'll see you in 15 years time, meaning he knows that he's done something seriously
00:42:48
wrong and that he's going to be going away for a long, long time. It's quite difficult to tell what he was feeling or thinking
00:42:57
just by looking at this, but on the face of it he seems pretty calm. AMBER HAQUE: A little later, Willis had a conversation
00:43:05
with one of his friends where he said, I don't think I'm going to be going to Benidormson.
00:43:10
I think I've killed someone. Just after 10:00 AM, Willis called a solicitor, he handed himself in at a police station and was arrested
00:43:19
on suspicion of murder. NARRATOR: The autopsy concluded that Andrew had died from a single stab wound.
00:43:27
AMBER HAQUE: The knife actually pierced his aorta, a major vessel in the body, and he died from catastrophic internal bleeding.
00:43:35
The police seized the knife which Willis still had in his pocket at the time, and
00:43:41
there was blood on this knife. They DNA tested it, and it was a match for Andrew Darn.
00:43:47
NARRATOR: The footage clearly captured the moment Alder Willis killed Andrew Darn.
00:43:54
FRANCIS FITZGIBBON KC: Quite often the critical moment is not captured, it's just off camera,
00:43:58
but here it was right in front of our eyes. MICHAEL DARN: It's hard to comprehend
00:44:02
how it happened when it had nothing to do with Andrew. You look back and you still say, why him?
00:44:11
He had so much going for him. He loved his job. He loved his partner. He loved his children.
00:44:21
He loved his fishing. And in the space of two seconds, it's all gone. NARRATOR: In court, Alder Willis argued self-defense.
00:44:33
FRANCIS FITZGIBBON KC: We had to prove that the killing was unlawful, which in this case meant we had to prove it
00:44:38
wasn't done in self-defense. Willis gave evidence at the trial and had to be asked about what he'd done.
00:44:46
He did accept that using a knife in response to a punch was out of proportion. The jury rejected his defense of self-defense.
00:44:57
- After an almost two week trial at Newcastle Crown Court, Willis was found guilty of murder and possession
00:45:04
of a bladed article. He was sentenced to life imprisonment with a minimum term of 18 years.
00:45:10
- He's going to be 86 when he gets out, but he's still going to get out, he's still going to have a life.
00:45:23
There's no life for Andrew now. FRANCIS FITZGIBBON KC: The jury clearly thought that whatever had happened in the past
00:45:29
and whatever happened that morning did not justify what Willis did to Andrew. He had done nothing to deserve that.
00:45:37
He didn't deserve to die. Not in that way, not at the hands of Alder Willis. MICHAEL DARN: I'd like people to remember Andrew
00:45:45
for being here fishing, his happy place where he was most at home, he was relaxed.
00:45:51
It was just his own little world. He loved this place. - For Andrew's birthday, we'd gone down to his favorite place
00:45:59
where he liked to fish, and would set off balloons with family. - Happy birthday, Andrew.
00:46:06
NATALIE DARN: It's the worst situation you could ever possibly imagine going through but you just
00:46:14
have to try to look on the brighter side because that's what he would have done.
