The Murder of Jessica Mitchell & Todd Gray | Killers Caught On Camera | Forensic Files

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