[DRAMATIC MUSIC] MAN 1: It just
sounds like something bad is happening to her. WOMAN 1: I heard her
scream, no, stop it. MAN 2: I heard some gunshots. MAN 3: Drop it! Whatever it is, drop it! MAN 4: That is not true
that I killed my wife. WOMAN 2: We know what
happened because the video tells us what happened. MAN 5: The camera doesn't lie. NARRATOR: This time on
"Killers Caught on Camera," in Knoxville, Tennessee,
a married couple are killed in their home
on the eve of retirement. [DOG HOWLING] As police discover body parts
abandoned around the house. STEVEN SANDERS: It's
pretty, pretty gruesome. NARRATOR: And in the
UK, a police officer is found dead in the woods
after a violent attack. Absolute catastrophic
head injuries. Worst I've ever seen. NARRATOR: As her colleagues
examine every angle to catch her killer. [THEME MUSIC] [POLICE SIRENS] [SUSPENSEFUL MUSIC] NARRATOR: Knoxville, Tennessee,
home to Lisa and Joel Guy, married for 31 years. HECTOR SANCHEZ: Joel Guy
Sr. was a hard worker. Just your typical
East Tennessean. Just a good guy. He worked as an engineer and
primarily worked in piping. Lisa Guy was a records
keeper and secretary for an engineering
firm here in Knoxville. NARRATOR: Joel had
three daughters by a previous marriage. And in 1988, Lisa
and Joel had a son together, Joel Michael Guy Jr. JAMIE SATTERFIELD: Lisa
Guy, by all accounts, was a really dedicated mother. I know that they
liked the outdoors. They liked being on the water. And in 2016, they were really
looking forward to retiring. They were preparing for a
new phase in their life. So they had spent most of
their life working and taking care of the children. And now the children were
up and out on their own. And that's what they
were looking forward to. When your kids get
up and out, you get to kind of be a couple again. They lived well and lived right. And they were getting ready
to enjoy the benefit of that. [DRAMATIC MUSIC] NARRATOR: Jamie
Satterfield has been an investigative journalist
for over 30 years. JAMIE SATTERFIELD:
It was Thanksgiving 2016 in East Tennessee. It's a really pretty time. So you have a lot
of fall colors. Lisa Guy, in getting
ready for Thanksgiving, she had decorated the house. Sisters were coming,
grandkids were coming. NARRATOR: Joel and Lisa
were also looking forward to seeing their biological son,
Joel, who would be returning home for the holidays. JAMIE SATTERFIELD:
I dare say she was probably a little
excited about that in that it had been a while. It was the setup
for-- would have been a really happy time for them. NARRATOR: With Joel Guy
Jr. living 600 miles away, this was a rare opportunity
for Lisa to spend some time with her son. JAMIE SATTERFIELD:
I know that Lisa was enjoying that time
with him because she was going to go to the store. And one of the things
that she was going to get was his favorite ice cream. Everything seemed, on the
surface, really good that night and the next morning. [OMINOUS MUSIC] NARRATOR: But just two days
later, Lisa was missing. She failed to turn up
to her last day of work and her own retirement party. JAMIE SATTERFIELD: The day
rolls around and no Lisa. So her coworkers
tried to call her. And, you know, she's
not answering the phone. And they knew that that was
not in Lisa's character. She just disappeared. Her coworkers grew
concerned enough that they reached out to the
Knox County Sheriff's Office. [DRAMATIC MUSIC] NARRATOR: Police officers
visited the Guys' residence and checked in with
their neighbors. Hector Sanchez was
Assistant District Attorney for Knox County. HECTOR SANCHEZ: Officers
were able to determine that the vehicles that were
registered to both Lisa and Joel Guy Sr. were present. They could also hear a faint dog
bark inside of the residence. NARRATOR: Police couldn't
get hold of Lisa or Joel on their phones. [OMINOUS MUSIC] HECTOR SANCHEZ: In looking
through the front window, they could see that groceries
were present in the foyer area. And in those groceries,
it was apparent to them that there was
perishables that were in those bags, things such as
ice cream, meats, and such. So that was obviously
curious to them. They did canvas around to
the back of the residence. [BEEPING] They were able to
determine that the door knob in the back
of the residence was completely missing. So, essentially, they could
see into the residence. When they looked
through that hole, they could feel an
immense amount of heat coming from that open portion. They could smell a
strong odor of chemicals. That was obviously
concerning to them based on the fact that
there was no contact with Joel and Lisa Guy. NARRATOR: The police had
to get into the house. They managed to get
access through the garage and found a back door. Steven Sanders was a
detective from the Knox County Sheriff's Office. He arrived on the scene
to an overheated house. STEVEN SANDERS: The
interior door was opened. And it was-- I mean, it was hot. It was-- it was
ridiculously hot. Police! Police Department
Sheriff's Office! When you go in,
there was obviously groceries on the floor. Sheriff's Office! [DOG HOWLING] There was animal feces
throughout the house and a dog barking. Knox County Sheriff's Office! [DOG HOWLING] And as they-- they got up
the stairs, you could see, you know, brown staining, which
they believed to be blood. [DOG HOWLING] Officers, obviously,
at this point have a heightened alertness. They are looking to not only
determine if someone's OK but also to determine
whether or not a suspect is present in the residence. [DOG HOWLING] On the top of the stairs they
found a collection of clothing that was covered in
what they believe to be human blood
that was appeared to be cut off of a human body. That was in a pile next to
a very large stain of blood. POLICE: We've got blood. [DOG HOWLING] STEVEN SANDERS: It's horrific. There's puddles of blood. There's human remains. You can't really
put that into words, but you'll never stop seeing it. It's pretty, pretty gruesome. HECTOR SANCHEZ: Officers cleared
the remainder of the upstairs and immediately made the
decision to back out. [DOG HOWLING] The gentleman saw hands? NARRATOR: Officers
surrounded the house in case anyone tried to flee the scene. It appeared the only living
being left in the house was a dog. The house was made a crime
scene and cordoned off. HECTOR SANCHEZ: Multiple units
within the Sheriff's Department moved in and they began
documenting the scene. [DRAMATIC MUSIC] NARRATOR: Potential weapons,
cash, and cleaning products were gathered as evidence. The police had to
find out what happened and who the body
parts belong to. STEVEN SANDERS: There's somebody
out there that's true evil, and we've got to get them. [OMINOUS MUSIC] NARRATOR: A suspicious
mixture of recently bought items provided
detectives with clues. Around the clothing were
several bottles of highly corrosive acidic-base solutions
such as muriatic acid, food-grade hydrogen peroxide
bleach, liquid fire Drano. And in the middle
of the bedroom, a workout machine
was-- was tipped over. That was an indication
to them that there had been some form of struggle. And officers in
the corner did find a very, very large
spot in the corner of reddish-brown substance. In the master bathroom
were two blue storage bins. JAMIE SATTERFIELD:
They look in there. Now there are these big
Rubbermaid containers. And then when they look
in there, there's torsos. NARRATOR: But the
worst was yet to come. JAMIE SATTERFIELD: They
get into the kitchen area. And what they see is
that there's a big pot-- a soup pot sitting on the stove. It is boiling. They weren't sure if it
was a water or a chemical, but they could see that this
had been cooking if you will. And they look into it. And when they look into it,
what they see is a human head. [OMINOUS MUSIC] NARRATOR: A gruesome discovery. Whoever decapitated this
body was still at large. They know nothing
about who may or may not have been in that home. All they know is that they have
a house full of body parts. And this chemical smell was the
other thing that was unusual. As here is somebody who has
taken extraordinary measures of chopping, trying
to boil away, to literally
dissolve these bones, make these bodies disappear. But, clearly, was
interrupted in some way because it was incomplete. The job was not done. Disposing of bodies,
especially when people dismember bodies,
always sounds and feels so incredibly gruesome. And it is objectively but
subjectively for the person who's doing it. They often describe it as going
into problem-solving mode. And the problem is that
they have this body. And the solution is anything
that will get rid of it. And so they're no longer
seeing these individuals as human beings. They're seeing them as
a problem to be solved. As a body to be removed. As objects, effectively. And so that can help us to
understand why it might seem less gruesome to the
person who's doing it and more just a necessity. [OMINOUS MUSIC] STEVEN SANDERS: We don't
know if it's a random act. We don't know if it's family. We don't know anything until we
start getting our-- our clues and putting them together and-- and piecing the--
piecing it together. But, right off the bat, you
know that whoever is responsible for this has got to be caught. [SUSPENSEFUL MUSIC] NARRATOR: Two vital
pieces of evidence gave the police a breakthrough. HECTOR SANCHEZ: We found
two receipts from Walmart. The first receipt was
found in the groceries that were left in the foyer area
just through the front door. Also in processing the crime
scene, the second level specifically, investigators
found an additional Walmart bag that had blood on it that had
medical supplies, including tape, ointments, things you
would use for serious wound, to treat, such as
a knife injury. In that bag was
a second receipt. JAMIE SATTERFIELD:
Receipts these days have timestamps on them. They send some folks
to go to the Walmart to review surveillance video
around that time frame. [SUSPENSEFUL MUSIC] NARRATOR: The Walmart
was only two miles from the Guy's family home. STEVEN SANDERS: Going
into the Walmart, being able to give them
a time-stamped receipt, we were able to pull a video
of what was taking place at that particular cash
register being checked out in the self checkout line. NARRATOR: The video
surveillance at the checkout helped the police identify the
person buying the groceries. STEVEN SANDERS: We were able to
identify some of the clothing we believed that was Lisa's. HECTOR SANCHEZ: They were able
to determine that just two days before that
Lisa Guy was in there buying those exact groceries. NARRATOR: The police now
had proof that Lisa was alive on the 26th of November. And that she made it
home with the groceries. When the police checked
the Walmart video footage for the time printed
on the second receipt, 3:30 PM that same day, they
made a surprising discovery. You can tell in the
Walmart footage this person, he's got bandages on. He's clearly injured himself. And he's buying some bandages
and things, it would appear, for his own cuts. They looked at this
surveillance video. And who they see
is the face that they've seen in that
house in family photos-- The son. NARRATOR: The son
of Lisa and Joel Sr. was 28-year-old Joel Guy Jr. [SUSPENSEFUL MUSIC] He lived in an
apartment in Baton Rouge over 600 miles away. He was working on his
undergraduate degree from the Louisiana
State University. And he had been doing so since
he was roughly 18 years old. He was a smart kid by all
indications, a smart young man and was working on potentially
becoming a plastic surgeon. NARRATOR: Joel Guy Jr. also
had a difficult relationship with his family. [OMINOUS MUSIC] JAMIE SATTERFIELD: What
was a little strange is that while the girls were
very close to their parents, their son really never
connected with his own family. From a very young
age, Joel Guy Jr., he wanted to be away from home. And as a child, he wasn't
sent to boarding school. He insisted on going
to a boarding school. NARRATOR: Lisa and Joel
Guy Sr. had been supporting their son financially. Lisa Guy worked for the
purpose of supporting him. She paid for his rent,
she paid for his food, she paid for his vehicle,
his car insurance. Joel Michael Guy Jr. never
worked a day in his life. NARRATOR: His parents
had had enough. They told him they planned
to stop supporting him so they could retire
more comfortably. Someone who's so dependent
on his parents, at this point, starts to wonder, well,
how am I going to survive if my parents cut me off? And that can lead to a
spiral of catastrophizing. Of thinking worse and worse and
worse potential consequences. And that catastrophizing
can make you think, well, the only thing I can
do is to somehow figure out how I can still get that money. And that might lead
you to fantasize about ways to do that. And fantasizing
can include maybe thinking about ways of
taking advantage of people or of maybe even killing people. [DRAMATIC MUSIC] NARRATOR: Two days
after Thanksgiving, Joel Guy Jr. was supposed to
be back home in Baton Rouge. But the Walmart footage
showed that he was still in Knoxville, Tennessee. HECTOR SANCHEZ: The distance
between Knoxville and Louisiana is pretty significant. I mean, we're talking
500 or 600 miles. A car drive of 8 to 10 hours. So to have Joel Michael Guy Jr.
still present in Knox County days after he was thought
to have been gone, that was significant
to our investigation. NARRATOR: On closer
inspection, the CCTV footage also revealed Joel Guy
Jr.'s physical condition. This angle of the
video for Walmart is real important to us. It's a self-check
out, which allows us to see the items
purchased, which match the items at the residence. It also allows us
to see his hands, which shows us that
he has injuries and wounds on his hands. NARRATOR: The police found
footage of Joel Guy Jr.'s car leaving Walmart,
which meant they could track his license plate. STEVEN SANDERS:
The FBI task force, they actually
located the vehicle and him in the apartment
back in Baton Rouge. So they just set up
surveillance and watched that while me and
Detective McCord began our travel to Baton Rouge. NARRATOR: When they got
there, they arrested Joel Guy Jr. He was taken into custody. Police found another trail of
receipts inside his apartment. HECTOR SANCHEZ: In connection
with the investigation, officers were able to ascertain
that Joel Michael Guy Jr. had been buying various supplies in
and around the Baton Rouge area in Louisiana. NARRATOR: 17 days
before Thanksgiving, Joel Guy Jr. was
captured on camera at Ace Hardware in Louisiana. STEVEN SANDERS: This video is of
him purchasing heavy chemicals, Drano, and so forth, that
were the same chemicals that were found here, which helps
us prove premeditation. This is him at a Home Depot
going through self checkout purchasing the garden
hose, purchasing a garden sprayer, bleach
sprayer, and a spray bottle. And we have him walking out. NARRATOR: Police
matched the items in the video with the same
items found at his parents' house in Knoxville. They also discovered another
chilling piece of evidence. JAMIE SATTERFIELD:
As the law enforcers are searching this
house, one of these rooms belonged-- or had at one
time belonged to Joel Guy Jr. And so when they
go into that room, they find he had
left a backpack. It had his laptop in it. But it also had this
college rule notebook. And when they open
it up, what they see is page after page after
page of handwritten notes. The best description
of its contents, I would call this a murder book. HECTOR SANCHEZ: His
notebook laid out that he wanted to render his
parents into a liquid form and then put them into
the public waterway before he lit the house on fire
to get rid of any evidence. NARRATOR: Joel Guy
Jr. was putting his detailed plan
into place in the days leading up to Thanksgiving. The video evidence was damning. HECTOR SANCHEZ:
Walmart, Louisiana. He is purchasing the bins. The blue bins are what we
located in the master bathroom with the human remains. 18 or 20 days before
these brutal murders, he's out in Baton Rouge
and the surrounding area buying all these
supplies that were all captured on
various surveillance closed circuit TVs. [OMINOUS MUSIC] STEVEN SANDERS: The
importance to it to us was it showed his
premeditation and his intent for what had happened
back in Knoxville. NARRATOR: Through DNA
analysis, forensic pathologists found that the body
parts in the house belonged to Lisa and
Joel Guy Sr. Their son, Joel Michael Guy Jr.
was charged with two counts of first-degree
murder and abuse of a corpse. JAMIE SATTERFIELD: When
you think about a case that involves someone who is accused
of chopping up his parents, the first thought, I think,
that anyone would have is he's got to be crazy. I'm certain that his
defense team would have loved to pursue an
insanity defense because they had nothing else. But he refused. It was almost as if he were
offended that anybody would be questioning his intellect. NARRATOR: Joel guy Jr. was
comprehensively captured by the net of surveillance. He was sentenced
to life in prison for two counts of first-degree
murder and dismemberment of his parents, Joel
Guy Sr. and Lisa Guy. At the trial, the full extent
of the horrific details of what happened were revealed. He did kill his father
first when his mother was out grocery shopping. And the reason he did that,
he could have accomplished the act of killing the
bigger threat, which would be his father. He did that in the upstairs kind
of spare bedroom/exercise room. We believe that perhaps his
father was engaged in working out when he was attacked. There was proof from
the medical examiner that he was stabbed in
the back multiple times. There's also proof that
Joel Guy Sr. fought back, which ultimately led to Joel
Guy Jr. obtaining a pretty serious wound to his hand. Further proof establish that
once Ms. Lisa Guy got home from Walmart, based on the
collection of the groceries that were not put
away with perishables, she was likely lured upstairs. In the minute that she
reached the top of the stairs is where she was
attacked and murdered. Joel Guy Sr. was
disarticulated at his hips and also at his
elbows and hands. Lisa Guy was decapitated. She was disarticulated
at the kneecaps. And we believe that
that was in order to render his
parents in a position where he could put their
remains in each one of those blue storage tubs. Despite the measures that he
took, the planning he took, his plan did fail. And I think a lot of the
reason his plan failed was based on the fact that
Joel Guy Sr. fought back. Joel Michael Guy Jr. had to
leave the state of Tennessee and drive roughly
500 to 600 miles to seek medical attention. We were able to determine
that he did come back to Knox County, where he likely saw that
his neighborhood was saturated with law enforcement
and decided to, again, leave and go back
to Baton Rouge. Parricide is when a
child kills their parents. Double parricide is when
a child kills both mother and father or both parents. It's rare for children
to kill their parents. It's even more rare for children
to kill both of their parents. So if a child is going
to kill a parent, it's usually one parent. And it's often a
boy who is killing their father or their mother. [SOMBER MUSIC] HECTOR SANCHEZ:
Joel Michael Guy Jr. was made aware that
his parents were going to cut him off financially. And when that was threatened,
he decided to kill his parents. JAMIE SATTERFIELD: It's the
coldest motive there is, greed. I'm sure he manipulated
his mother all the time. And for once, she
was standing firm. Even though it upset her,
she was standing firm. And I think he realized
that the gig was up. And that's when he put this
murder book plan into place. NARRATOR: Joel Guy Jr. hoped
by killing his parents, he would receive
all their savings and life insurance money. But there was another twist
to his financial motive. An emotional one. STEVEN SANDERS:
He was homosexual. He had a partner that
lived with him for a while, and then they separated. And they were friends, but Joel
Guy Jr. wanted to be with him. And the other individual
did not want to be with him. NARRATOR: The individual in
question was Michael McCracken. And in jail, Joel
Guy Jr. made a call to Michael, where he
revealed his motivation for killing his parents. He wanted the
inheritance for himself to change his appearance and
make the love of his life want him. He did this to take
all the inheritance to change his appearance to make
his significant other want him. And that's basically it. JAMIE SATTERFIELD: What was
particularly disturbing, when you look at
that murder book, is that while he's seated at
the family table on Thanksgiving and he's being friendly and
loving on his family, all the while, his instruction
manual for killing his parents is up there in his bedroom. And they had no idea. HECTOR SANCHEZ:
The role of cameras as it relates to this
particular case was tremendous. All the security
surveillance footage that we had at various locations. I do believe that it would have
been a lot harder to present the case in the way
that we were able to and to corroborate theories that
we had about the premeditation and purchasing items and-- and utilizing them
in the commission of these brutal murders. STEVEN SANDERS: The
cameras are very important because there's no-- there's
no disputing who this is and what is being bought and
what was at the crime scene. HECTOR SANCHEZ: This case
is obviously one that no one wants to be a part of. It's a very heavy case. The loss of life and the
manner in which these folks were murdered is just brutal. JAMIE SATTERFIELD: He's
the strangest defendant that I have ever encountered. There is something
missing in his soul. STEVEN SANDERS: How
can a person be so-- so cruel and brutal, not only
to just somebody but family. It's a day that you
won't ever forget. [DRAMATIC MUSIC] NARRATOR: Researchers found
that since at least 2020, CCTV has been used more
often than any other kind of forensic science
or technology to identify and charge suspects. Cameras are vital
in helping track and place suspects in or
around the scene of a crime. The Hamlet of Snowdown
near Aylesham in Kent. Home to 53-year-old Julia James. Julia had recently remarried. She had two children from
two separate relationships. KIRSTY BENNETT: Julia
James was a police community support officer. And she was really well-known
in the area because of her role as a PCSO. And she was really
outgoing, friendly. She was a massive part of the
Kent Police community as well. GAVIN MOSS: She was a DA PCSO,
so Domestic Abuse Policing Community Support
Officer supporting victims of domestic abuse. And she was there to help. And that's what
she wanted to do. NARRATOR: Julia lived
next to a Akholt Wood and often walked her Jack
Russell, Toby, in the Woodland and countryside which
surrounded her home. Kirsty Bennett is a
lecturer in criminology at Leeds Beckett University. Julia used to
walk or jog quite frequently in a wood, which
was at the back of her house. And while she was there,
she came across a man on a couple of occasions
lurking which made her feel quite uncomfortable. NARRATOR: Gavin Moss is a
senior investigative officer at Kent Police. GAVIN MOSS: Julia had
expressed some concerns about a male she'd
seen, I think, on two or three occasions. She described the person
saying that he was in the area of Akholt Woods. And gave her some
cause for concern. This was never ever reported. And that's no
criticism of anybody because people do
see things like that and things don't
always get reported. NARRATOR: Julia told
her husband Paul that she'd passed
a really weird dude on the Akholt Wood bridle path. And on another day when
Julia went for a walk with her husband, she pointed
out the same man to him. GAVIN MOSS: Paul
James, Julia's husband, mentioned that he'd seen
this person in February, so February 2021, in
the area of Akholt Wood. Woman typically wait for 19
separate incidents to occur, either threats or
incidents where they feel like they've
been watched, before they report it to police. So you need to have really
seen that person quite a lot in order to raise the alarm
and go to authorities. NARRATOR: After their
encounters with the strange man in the woods, Julia
and her husband avoided their usual
dog walking route. And as an extra precaution,
Paul bought Julia a smartwatch. That was there as an extra
security safety measure, so she could quickly alert
people if she felt unsafe. And that allowed her to
go back into the woods after taking a break
from not visiting. NARRATOR: On Tuesday the 27th of
April at 2:12 in the afternoon, Julia left her house
and took her dog, Toby, for a walk in the nearby woods. At 2:23 PM, she was
spotted on a distant CCTV camera walking through a gap
in a hedge near Akholt Wood. GAVIN MOSS: This video clip
is from a local business that overlooks the Akholt Wood area. And what it actually
shows is an image of somebody walking along here. NARRATOR: This CCTV was
cross-referenced with GPS data from the smartwatch. GAVIN MOSS: We were able to say
that that individual was indeed Julia James. It showed the exact route she'd
taken from her home address. About 8 minutes after she
appeared in the footage, Julia's smartwatch
detected a big change. KIRSTY BENNETT: Her smartwatch
indicated that her heart rate rapidly rose from 97 to 145. So we can see that
something's a problem. She's moving very quickly. NARRATOR: The smartwatch
data also showed Julia made a detour from her usual route. GAVIN MOSS: It was awful
viewing to see her Apple Watch and her heart rate
change dramatically. It was very clear to
see that she'd run away. Our take on that she
was being chased. NARRATOR: An hour and a
half later, a local family were walking in the woods
and came across Julia's dog wandering alone. GAVIN MOSS: I saw Julia's dog,
Toby, but without an owner. They then went to investigate. And, sadly, that's when
Julia's body was found. [SOMBER MUSIC] KIRSTY BENNETT: Julia
suffered very traumatic, blunt force trauma injuries. She had a broken wrist. She had multiple lacerations and
injuries to her skull and face. The offender took strides to-- to really injure Julia. GAVIN MOSS: She stood
no chance of survival and died very, very quickly. And, fortunately,
didn't-- didn't go through too much pain. Police were on the hunt for
the person capable of carrying out such violence. GAVIN MOSS: At the
time, understandably, there was a lot of concern, a
lot of fear in the community. One of my first thoughts
is, is this person going to strike again? Will we end up having another
murder that could follow? NARRATOR: The police
started to search the area where Julia's body was found. GAVIN MOSS: The area
was absolutely enormous. It is by far the biggest scene
that I've ever dealt with. We use licensed
searched officers to undertake what we call line
searches, fingertip searches. We used a drone. We had forensic recovery
dogs out as well. NARRATOR: Gathering
video evidence was crucial to the case. GAVIN MOSS: I remember
saying at one of my briefings be creative. Think about other opportunities. Think about buses. Think about lorries. Think about delivery drivers. Get it as open as we
can to make sure we capture everything possible. In terms of footage
that we had to view, it worked out to 6,700
hours worth of footage. NARRATOR: But digital forensic
analysts spotted something. Just under two hours
before Julia was murdered, CCTV captured a person in
Aylesham carrying a bag. GAVIN MOSS: You can see that
he's walking in the direction of a gap in a tree line. This individual was carrying
something in his bag. You can't get any facial
identification of him. NARRATOR: 31 minutes
later, what seems to be the same
person was spotted, again, and then, again,
leaving the area at 3:45 PM. GAVIN MOSS: What really helped
is that this also coincides within the time
frame of, obviously, after Julia was
brutally murdered. So all starts bringing it all
together about his movements pre and post what
tragically happened. [SUSPENSEFUL MUSIC] NARRATOR: As well
as the CCTV footage, police also investigated
potential witnesses who'd been driving in
the area around the time of Julia's murder. After such a
high-profile incident, the community was on high alert. And a critical piece
of dashcam footage was recorded by local
gamekeeper Gavin Tucker. [INAUDIBLE SPEECH] [INAUDIBLE SPEECH] [INAUDIBLE SPEECH] MAN: [INAUDIBLE SPEECH] GAVIN MOSS: He described
the location he'd come from was the-- the crime scene. And that's what aroused
Mr. Tucker's suspicions. [DRAMATIC MUSIC] NARRATOR: The
suspicious character hastily left the scene. Gavin Tucker needed to act fast. He then runs away and
runs along Adisham Road. And as you can see
here, he cuts across and runs into the wooded area. Of particular interest
to us was this item here, which was being carried. NARRATOR: The pathologist's
report gave the police critical information
about the type of weapon that was used to kill Julia. GAVIN MOSS: From
the post-mortem, the pathologist
said to me they're looking for something
cylindrical, linear, and heavy on one end. NARRATOR: The weapon used to
kill Julia hadn't been located near the scene of the crime. Police were looking for
anything which may have fit the pathologist's description. As well as the dash cam
footage, Gavin Tucker managed to take a photo of
the suspect in the field before he ran off. GAVIN MOSS: We circulated the
image to the general public. I wanted the whole
deal to be cropped, so we didn't show exactly
what that was, in the event that we could, hopefully,
locate that in the future. NARRATOR: When police released
the image to the media, a witness identified the suspect
as 21-year-old Callum Wheeler. [OMINOUS MUSIC] Police arrested Callum
on Friday the 7th of May, 10 days after
Julia was murdered. GAVIN MOSS:
Barricading himself in, protesting his innocence
right from the beginning, and he resisted arrest. Within his bedroom,
just over this side, there is what we believe
to be the weapon, which then was subsequently seized. NARRATOR: The weapon, still
propped up against his bedroom wall, matched the
item he was seen carrying before and
after Julia's murder. GAVIN MOSS: The
weapon that was used was actually a
railway jack handle that is used by the
railways to lift tracks effectively on a jack. Was made of fiberglass and
consistent with exactly what the pathologist said. It was linear, cylindrical, and
it was very heavy on one end. NARRATOR: Once Callum
was taken into custody, the police began building
a case against him. GAVIN MOSS: We didn't
know a great deal about Callum Wheeler. From a police intelligence
point of view, very little was known about him. And he was a complete
loner in life. He had no friends. He'd lived in Aylesham. He'd been in Aylesham
for a couple of years. He came from South East London. And apart from that, we
didn't know a great deal more. As part of the
investigation, detectives are looking to
create a narrative of the event to support
a successful prosecution. NARRATOR: DNA evidence
was vital to put Callum at the scene of the crime. GAVIN MOSS: What we
were able then to show was that we had Callum Wheeler's
DNA on Julia's clothing. But also on the weapon,
we had Julia's DNA. We also had, on
his training shoes, presence of Julia's blood. He was charged. He appeared at court. And he was remanded in custody. NARRATOR: In court,
the full details of what happened to Julia James
on the 27th of April, 2021, were revealed. GAVIN MOSS: Callum Wheeler had
ambushed her and subjected her to an absolutely brutal
and horrific murder causing absolute
catastrophic head injuries. Worst I've ever seen. KIRSTY BENNETT: The
extent of the injuries is not a common
occurrence because we know that Julia was
likely unconscious from the first injury. And we're seeing
the multiple attacks afterwards, which
is not necessarily needed to cause death. Julia was not sexually
assaulted in the sense that she was the
victim of a rape. We know that because of the
forensic analysis that we did. But there were a few
significant issues in relation to Callum Wheeler that
we were able to establish during the course of
the investigation. The presence of Callum
Wheeler's DNA on a vest top that Julia had been
wearing at the time. And that didn't
happen by accident. She was wearing a jacket. She was also wearing
a jumper as well. And the vest top was
underneath those items. So, you know, he-- he
had touched her breast. And that all came
to what we said was a sexually motivated murder. [OMINOUS MUSIC] NARRATOR: Callum Wheeler's
internet search history also showed that he'd
searched the word rape just two days before Julia's murder. And his actions after he was
arrested were disturbing. When he got arrested, taken
into the police station, he exposed himself to a female
police officer and masturbating in front of that
officer, which would have been absolutely horrendous
for that individual officer to see. NARRATOR: Had he
not been caught, the police believed
this could have been the first in a series of
attacks on women in the area. GAVIN MOSS: I can't ignore the
fact that he was walking around with that weapon, you know. Was it because he
wanted it as a trophy? Or was it because he
would have killed again? Only one person knows that
and that is Callum Wheeler. Because I'm a detective
of many years, you know, I can't help but
think that, potentially, we could have had another. [SOMBER MUSIC] NARRATOR: Without the
videos, the prosecution may not have had enough evidence. KIRSTY BENNETT: Surveillance
footage and things like CCTV are so important for
tying weapons, belongings to an offender and the
victim and identifying sequence of events. So what was the offender
doing beforehand, what were they doing after
the event, that we can put together into that story. GAVIN MOSS: Had we not had
CCTV, we wouldn't have seen him holding the weapon before. We wouldn't have seen him
holding the weapon afterwards. That could have presented
a defense for him, that he'd found the weapon. NARRATOR: Callum Wheeler was
sentenced to life in prison with a minimum term of 37 years. GAVIN MOSS: I went
to the funeral. And the impact of Julia's murder
was absolutely significant. Did I treat this any
differently to any other murder? I didn't because I
needed to catch him. We needed to catch him
because it was quite clear he was a brutal individual. But it is something
different and difficult when it is one of your own. [SOMBER MUSIC] [DRAMATIC MUSIC]
