00:00:00
[Music] up next an execution-style murder and a sophisticated cover-up it was obvious right from the start that
00:00:14
this crime scene had been altered and i witnessed these two men leaving the scene but how much did he
00:00:20
really see we were scratching our heads for a little bit someone held a grudge against
00:00:24
the family maybe he was angry enough to come back in her bed on brian she was definitely
00:00:29
scared of this guy but was that enough to lead to murder [Music] eight months after getting married brian
00:00:44
and beverly mark moved into their dream home in rural washington state she loved him so much he loved her so
00:00:53
much too yeah i mean it showed in their eyes thirty-year-old brian worked for an air
00:00:58
conditioning company beverly 28 was a secretary at a car dealership a mutual love of sports brought the two
00:01:06
together he had been the same sports that she had been in and they love showing their scars off each of them and
00:01:13
you know and where they got this and where they got that and so they were they were a wonderful match
00:01:22
at 5 a.m on a november saturday morning a friend arrived at brian mark's home to
00:01:27
pick him up for a day of hunting he said that the house was dark and so he didn't bother
00:01:34
knocking on the door to see if brian wanted to go he just went hunting by himself
00:01:39
the friend called later that morning but no one answered so he drove back over to
00:01:45
brian's house the front door was locked he could see the television was on and what looked
00:01:52
like a body lying on the floor [Music] that's when he called police i just remember it was
00:02:00
just very very bloody blood everywhere they found both beverly and brian mark had been murdered i broke down
00:02:12
and and was screaming and i was like i have to get out there i have to get out there
00:02:17
i have to see for myself each of them had been shot three times at close range with a 22
00:02:24
caliber pistol there was definitely an execution style element to it it looked like they had been shot and
00:02:31
then shot again to make sure they were dead i just wanted to go in and hold my daughter but i knew i couldn't because i
00:02:40
knew that it would destroy police evidence or possibly from the location of the shell casings
00:02:48
it appeared that brian was shot in the living room beverly most likely heard the shots from
00:02:54
the bedroom and ran out to see what was going on she made a run for the front door and our
00:03:00
suspect caught her at the front door and that's where he shot her [Applause] the evidence shows that the killer
00:03:10
dragged beverly's body next to her husbands and covered them both with a sheet from
00:03:15
the bedroom this was essentially a swath of blood two or three feet across and 10 to 15 feet long that leads
00:03:24
right to the victims bodies there were unusual striations in the blood trail we just could not figure out what caused
00:03:32
that particular pattern when we first saw it we were scratching our heads for a little bit trying to figure out
00:03:38
what caused that particular blood pattern the answer was found in the kitchen someone had swept the broom through the
00:03:47
blood and spattered it up onto the wall the killer might have used the broom to remove his shoe impressions
00:03:55
he also used a rag to remove other evidence they're trying to eliminate fingerprints
00:04:00
like the doorknobs the light switches that sort of thing and what they used to do that with had blood
00:04:07
on it because there was blood smears on the light switches and there was blood smears on the doorknobs
00:04:12
the fact that television was on told investigators even more there was no fast i gotta get out of
00:04:20
here there was very deliberate cleaning up covering up trying to hide what had happened
00:04:26
the motive didn't appear to be robbery brian had a considerable amount of cash uh on his
00:04:33
person there were guns in the home that were not taken they were a number of valuable
00:04:39
items were undisturbed and the evidence suggested brian opened the door then turned his back
00:04:48
to walk towards the living room when he was shot a clear indication he knew his killer
00:04:58
brian and beverly mark were murdered in their home in the middle of the night their family
00:05:05
said the couple had no known enemies it breaks my heart she can never be a mother she wanted
00:05:11
that so bad and i know brian wanted to be a father so bad and they had so much to offer
00:05:18
they just were two of the nicest trustworthy people their kids would have been perfect
00:05:26
[Music] the killer spent several hours cleaning the crime scene it's a risky thing to do of course the
00:05:37
longer a criminal stays at the scene the greater the risk that they're going to leave evidence behind
00:05:42
or leave a telltale clue and that's precisely what happened the killer inadvertently left clues
00:05:51
while cleaning up after he covered the bodies with a sheet he stepped on it the bottoms of his shoes were clean but
00:05:59
he created a shoe impression in the blood on the floor underneath the sheet it was a zigzag
00:06:07
pattern or a very distinct shoe mark that you could see um left in the in the blood the fact
00:06:14
that the killer spent so much time at the scene aided in the discovery it had been dried for a
00:06:21
while it's probably helped things at least preserve the print in the floor anyway
00:06:26
a computer search of the shoe patterns indicated this was a madison brand work shoe
00:06:33
the killer also left evidence in the couple's bedroom looked like a fingerprint could have
00:06:38
been on a door jamb in the southeast bedroom but the ridge characteristics were in
00:06:45
a u-shape meaning the finger would have been upside down that would make sense except this print was five feet from the
00:06:56
floor someone would have to be standing on a ladder to leave a print like this it just was too high for it to be
00:07:05
placed there by a finger for a natural placement of a hand on that location but there was another possibility
00:07:15
the rich detail of palm prints runs in the opposite direction of ridge detail on fingerprints the fingerprint
00:07:24
that we had from the house wasn't actually a fingerprint but it was a palm print
00:07:30
i'm thinking that he left the bloody palm print on the door jamb when he was using it to balance himself
00:07:36
when he was cleaning something else up perhaps with a paper towel not realizing that his hands got blood on it and it's
00:07:43
resting on the uh the door jamb law enforcement has a separate database for palm prints called
00:07:49
morpho unfortunately this one didn't match any in the database in a search for suspects police questioned everyone in
00:07:59
the sparsely populated neighborhood a couple across the street daniel and jennifer tavares
00:08:06
said they heard gunshots around 7am they thought the shots were from hunters daniel got up and looked out the bedroom
00:08:18
window which faced the mock's house he saw a red pickup truck leaving the mock's
00:08:24
driveway he said there was a passenger whom he didn't get a good look at he described a
00:08:28
driver however in great detail a white male roughly six two in height perhaps 230 240 pounds
00:08:37
with long hair and a ponytail the truck turned around in the cul-de-sac and sped away
00:08:45
neither family nor neighbors knew anyone matching the driver's description police
00:08:52
began checking the hundreds of red pickup trucks in pierce county meanwhile beverly's mother pointed to
00:08:59
another suspect i know she was afraid of somebody that he brought into their home and
00:09:06
i think she shared that with her brian he was 21 year old jeremy flynn who lived just a few houses
00:09:13
away he had a juvenile arrest he was a suspect in some other crimes i think he was a suspect in a burglary
00:09:19
and a suspect in a theft witnesses said jeremy attended a party at the mock's home about six weeks before the murders
00:09:27
flynn was so drunk and belligerent that brian asked him to leave the two argued and almost came to blows
00:09:36
whatever took place at that party or afterwards definitely left an impression on beverly
00:09:42
and she was definitely scared of this guy and she was nervous about this young fellow
00:09:48
didn't like to be alone at the residence when her husband would be away the morning after the
00:09:54
party the mocks discovered items missing from their home and they confronted jeremy about it the
00:10:01
handgun that belonged to brian was stolen and i believe beverly's cell phone or or one of their cell
00:10:09
phones had been taken and so i figured maybe he was angry enough to come back and
00:10:14
hurt bev and brian but the handgun wasn't a 22-caliber like the one used in the murders
00:10:21
jeremy didn't own a red pickup truck and three people provided alibis for jeremy for the time
00:10:29
of the murders had almost been completely eliminated as having anything to do with this whatsoever
00:10:37
so police went back to their only eyewitness except this time his story began to change
00:10:51
in the search for beverly and brian mark's killer police went back to the mark's neighbor
00:10:58
daniel tavares who describes seeing a red pickup truck outside the crime scene around the time of the murders his
00:11:06
description of the two men inside was detailed the more detail that a witness can give you an eyewitness to
00:11:13
someone who might well be associated with a crime scene the better it is but for the detectives
00:11:21
it was too detailed tavares lived 200 yards away from the mock's house and it was still dark outside
00:11:31
he gave descriptions of these men and i mean from hairstyle to how many days had been since one of them
00:11:39
had shaved to color their shirt the types of shoes they were wearing he even went so far as it described this
00:11:46
person was having a pock marked face when detectives did a background check on daniel tavares
00:11:54
they were shocked by what they found tavares had served 16 years in prison for manslaughter
00:12:01
and he just been released four months earlier daniel tavares by all accounts was the
00:12:07
worst type of prisoner argumentative combative assaulting jail guards and somehow gets out with credit
00:12:17
for good time before he was released from prison tavares met his wife jennifer freitas
00:12:24
through a computer dating service where convicts post personal ads hoping to find pen pals
00:12:32
and that's how jennifer ends up developing this relationship with him i think for most of us it's
00:12:39
incomprehensible that that's the place you go to find love they communicated through email
00:12:45
but never met in person until tavares was released as soon as he gets out there he is on a
00:12:51
plane leaving massachusetts and coming out to washington state that was shocking enough i think when we
00:12:55
learned that divorce married jennifer in washington state and had violated the terms of his parole by
00:13:03
leaving massachusetts unfortunately local police in washington had no jurisdiction to arrest him
00:13:12
the warrant was limited to i believe states that joined massachusetts or new england area
00:13:20
so while there was a warrant for his arrest it was limited to that small geographical area
00:13:27
police in washington state could get tavares fingerprints from massachusetts but what they really needed were his
00:13:36
palm prince so investigators wanted to get him into police headquarters and somehow find a way to get him to
00:13:44
provide his finger and palm prince voluntarily fortunately tavares didn't know he was a suspect
00:13:53
he was cooperating he was bending over backwards he was thinking that we were buying his
00:13:58
stories their idea was to ask tavares for help in preparing a composite sketch of the mock's killers
00:14:07
i just thought that it would be easier and safer to get him down here thinking he was coming down here voluntarily on
00:14:14
his own to talk to a sketch artist as daniel tavares walked into police headquarters
00:14:20
detective jason tate arrived at about the same time and followed him into the building
00:14:26
it had just rained and tavares was tracking wet shoe prints onto the floor of the entrance way
00:14:33
detective tate thought they looked familiar i needed to get inside and get somebody
00:14:39
out there before things started to dry and disappear mary lou hansen o'brien rushed out with her camera because the
00:14:47
print was in water on a rough surface it was impossible to compare fine detail but the treads on the shoe
00:14:55
were clear and distinctive and it was a unique pattern there was not a lot of detail to the pattern was this the same
00:15:06
shoe that left the single bloody shoe impression at the crime scene criminals are not
00:15:13
real smart i've just seen time and again that criminals do stupid things [Music]
00:15:21
daniel tavares was the prime suspect in the murders of his neighbors brian and beverly mark but investigators
00:15:29
had no idea about a possible motive i interviewed a bar manager who had served tavares
00:15:37
that night of the murders and he described him as cocky and arrogant and somebody who was
00:15:43
looking for a fight daniel tavares walked into police headquarters not realizing he was a suspect he thought he
00:15:51
was there to provide a description of the killers he had no clue he he thought that he was down here to
00:15:58
talk to a sketch artist and he had no clue that we were on to him at that point tavares admitted he'd been inside the
00:16:05
mock's home several times for social visits so police asked if he'd mind providing
00:16:11
his fingerprints so they could eliminate his prints from all the other unknown prints they found
00:16:17
inside the mock's home so that's how i presented it to him i just said we need to be able to
00:16:22
eliminate the prints that aren't important to us tavares was happy to oblige and police took not only his
00:16:30
fingerprints but also his palm prints then investigators asked tavares some more
00:16:38
pointed questions about his past i'm sure you must know what i was in prison for i just heard it was
00:16:45
manslaughter how'd you kill him step it was a her oh it was yeah it was hmm family member what
00:16:59
what kind of family member mom you killed your mother yeah i did no kidding i said you killed your mother i i was
00:17:12
taken i was i was shocked within minutes latent print examiners matched tavares palm print
00:17:21
to the bloody palm print on the door jamb at the crime scene at this point in time
00:17:26
we've got uh evidence to arrest you for the murder of brian and beverly what i was in bed that's impossible
00:17:34
i don't normally do this but i'm going to show you something this is your print in blood
00:17:42
that we recovered inside that house these are the patterns on your shoes that you have on your feet
00:17:51
right now when i saw the impression i could not believe that i was seeing that same footwear pattern we were just
00:18:00
baffled that again tavares was was stupid enough to have those shoes on his feet right now faced with the
00:18:10
forensic evidence daniel tavares confessed he said he had given brian mark a tattoo
00:18:17
and that brian owed him fifty dollars so he went over early saturday morning to get it
00:18:28
[Music] he said it was early brian was asleep and was angry tavares had awakened him
00:18:39
they argued tavares snapped and shot brian three times in the head beverly heard the shots and tried to
00:18:50
escape tavares shot her three times then dragged her body next to her husbands when he went to the bedroom to grab a
00:19:06
sheet to cover the bodies he may have left some blood on the light switch in the bedroom
00:19:11
when he wiped it off he left a partial palm print on the door he must have been steadying himself as
00:19:19
he cleaned the plate over the next several hours tavares used a broom to get rid of his shoe prints
00:19:28
but when he stepped onto the sheet covering the bodies his weight created a shoe impression
00:19:33
in the drying blood on the floor under the sheet a shoe impression he wouldn't see simply
00:19:40
by looking at the top side of the sheet jennifer tavares later admitted she was at the crime scene
00:19:48
after the murders jennifer also admitted she and her husband later threw the murder weapon
00:19:56
into nearby puget sound what led up to his decision to kill brian mark remains a mystery tavares claims that
00:20:08
it was because of an insult but i don't know that i buy that in february of 2008
00:20:17
daniel tavares was sentenced to life in prison without parole jennifer tavares who claimed she only helped her husband
00:20:27
with the cover-up because she feared for her life got one year i can't even explain why i did it
00:20:34
because i wasn't able to think straight the time and i'm scared worried about my family
00:20:41
tavares is so stupid that he wore his same shoe into his interview at the police station
00:20:49
with a detective you don't want to rely on just one little bit of evidence and and
00:20:55
discount everything else everything matters this is the first case for me that the rain actually
00:21:02
helped out a little bit we don't have a clear motive as to why a murder happened
00:21:08
and i don't think we're ever going to know in this case
