- MALE NARRATOR: In August 1981, 91-year-old Henry Walsh was held up at knife point in his small hardware store
00:00:12
at Ormskirk, Lincolnshire, in England. The elderly shopkeeper refused to yield to his 18-year-old assailant.
00:00:21
He would pay with is life in the most horrific way. - Obviously threatened him with a knife,
00:00:26
two or three times. You could see minor marks on his clothing, and then he just pushed it through his chest.
00:00:34
And he's actually hanging on it on the door. - NARRATOR: The perpetrator was Andrew Dawson,
00:00:40
a known local thief who'd suddenly matured into a vicious murderer. He would spend the next 17 years behind bars,
00:00:50
but that did nothing to dull his killer instinct. - Almost inevitably as night follows day,
00:00:59
Dawson was going to kill again, it was only a question of when. - NARRATOR: Almost 30 years after his first killing,
00:01:08
Dawson was a free man with murder on this mind. In 2010, police in Derby would discover
00:01:16
two of Dawson's neighbors dead, but the convicted killer was nowhere to be found.
00:01:22
- This guy kept me awake at night because you just had this feeling that you had
00:01:25
to get the evidence, you had to put him away because he was an absolute danger to anybody in society.
00:01:30
- NARRATOR: Andrew Dawson had proved himself to be one of the world's most evil killers.
00:01:36
- ♪ - NARRATOR: In July 2011, Andrew Dawson pleaded guilty to the double murder of two of his neighbors
00:02:05
and was sentenced to spend the rest of his life behind bars. It was the end of the road for the 48-year-old killer
00:02:14
who chillingly christened himself the Angel of Mercy. Dawson was no stranger to prison,
00:02:23
he'd already served time for murdering a popular shopkeeper in his hometown of Ormskirk in 1981,
00:02:29
when he was just 18. Local journalist Clifford Birchall covered the story of the brutal murder in the unassuming town.
00:02:41
- Ormskirk in the 80s was just a small country Lincolnshire town. They had a market that was on the streets
00:02:48
twice a week; came alive on those days. Just a small friendly place. Everybody seemed to know everybody and it was just
00:02:56
an ordinary place, nothing exciting happened very often. - NARRATOR: That was all to change in August 1981,
00:03:05
when 18-year-old Andrew Dawson entered a small hardware shop owned by popular pensioner, Henry Walsh.
00:03:14
- CLIFFORD: From what we learned from the, uh, evidence, he'd just gone in, he'd been looking for money
00:03:19
and he thought that Mr. Walsh would be a soft touch. He was, you know, 91-years-old, he wouldn't put up
00:03:26
much of a fight, he would, you know, do as he was told. But, uh, it turned out however more spirit
00:03:32
than Andrew Dawson thought he had. He refused to say where his money was. He refused to help him, sort of tried to get him out
00:03:38
of the shop and then he paid for it with his life. - NARRATOR: After serving seventeen years for the crime,
00:03:46
Dawson was released in 1999 and settled down in Derby with a wife and two children, but just over a decade later,
00:03:54
the killer found himself living alone in a flat and his lust for murder returned.
00:04:00
Former detective, Paul Callum investigated the killing of two of Dawson's neighbors in 2010.
00:04:08
- The people who lived in this block of flats, or his victims, were vulnerable for some reason,
00:04:12
either sort of, they're a little bit older and they've got ill health, uh, or alcohol problems
00:04:17
and this sort of thing, and I think Dawson knew that and he picked on vulnerable people
00:04:21
because he knew he could overpower them, and he knew he could control them. - NARRATOR: This killer's story begins in the market town
00:04:31
of Ormskirk in Lincolnshire, in the north of England. - Dawson was born in 1962 and he was one of six children and the family
00:04:40
were quite impoverished, they didn't have alot of money, so I think times were pretty tough.
00:04:46
He did have a very strict and domineering father, but that's nothing out of the ordinary,
00:04:51
and his relationship with his mother, doesn't seem to have a flagged up any concerns either, so his--his family life
00:04:59
wasn't particularly out of the ordinary. - NARRATOR: But even from a young age, Dawson displayed signs that he was in for a life of crime.
00:05:10
- GEOFFREY: He grows up in straightened circumstances in Ormskirk. A boy who wants whatever he wants,
00:05:17
whenever he wants to get it. When he's six or seven, he sees a little girl with money,
00:05:21
pennies literally, and steals them, because he can, because he feels he can get away with it,
00:05:26
because it doesn't matter. DR. YARDLEY: He had a very acute sense of entitlement.
00:05:30
If he wanted something, he would just literally go and take it, there were no moral
00:05:35
or ethical boundaries there whatsoever, and I don't think that behavior was ever really challenged.
00:05:42
There were never really any serious consequences for that and if there were, he didn't care.
00:05:48
So, this was somebody who was psychologically not quite normal. - In my view, Dawson was a sociopath
00:05:56
from a very, very early age. He did not know a responsibility. He did not know moral values, he did not know conscience,
00:06:02
he did not know forgiveness, he did not know saying sorry; grab it, "I'm gonna take it, it's mine, I want it."
00:06:11
- LOUIS: The majority of individuals who commit juvenile crime, petty or otherwise,
00:06:16
usually turn themselves around as they mature out of it. The younger someone is when they begin their criminal behavior,
00:06:26
the worse the prognosis is, the worse the outcome is, and so, when you look at Dawson's background,
00:06:32
what stands out to me from a distance is he was involved in crime right from the beginning,
00:06:37
he was a problem child, right from the start. - NARRATOR: As Dawson matured, so did his crimes.
00:06:45
- DR. YARDLEY: As a teenager, Dawson engaged in property crime. He committed a range of petty thiefs and the victims
00:06:52
he would target would be elderly people, and I think he was-- he was quite aware
00:06:57
of the vulnerability of the elderly, of the fact that they might keep money in their houses
00:07:02
or their work places. - NARRATOR: The burgeoning criminal was soon on the radar of the local authorities.
00:07:10
- Andrew Dawson had come to the attention of the police in the past, uh, through just, uh, petty thief.
00:07:15
He wasn't known to them, I don't think they thought he was one of the great criminals of the town,
00:07:20
but he was just perhaps more a nuisance than anything else. - NARRATOR: There appeared to be nothing obvious
00:07:27
in Dawson's young life that justified his criminality. - He had five siblings, they're not all
00:07:34
committing crimes and killing people, no, it was Dawson, he's the only one. He grew up in the same family with them.
00:07:41
The parents treated them, generally speaking, the same, according to all the other family members,
00:07:47
no, it was Dawson, it's within him. It wasn't an event that happened that created him,
00:07:53
it's who he was. - DR. YARDLEY: I think there was very much a sense of competition between Dawson and his siblings.
00:08:01
It's always that vying for attention and there are six of them, so I think that they're always
00:08:07
trying to outdo each other, and that's the case in many large families, but I think Dawson took it
00:08:14
a little bit further than most. He had a significantly antagonistic relationship
00:08:19
with his brother, he stole money from his brother. - NARRATOR: It was the final straw,
00:08:25
Dawson's brother reported him to the police and the young criminal was arrested and charged with theft.
00:08:33
- CLIFFORD: That was enough to have him sent to boarding school for, uh, about six months.
00:08:37
And then sort of, when he was released, he came back Ormskirk, but obviously, you know,
00:08:43
hadn't really learned from his ways. He just carried on as he-- as he had before.
00:08:48
- Somebody like Dawson and other extraordinary offenders who particularly those who commit
00:08:53
multiple crimes, they see the world differently then the average person, they function in a different sphere.
00:09:01
And so where punishment may help somebody straighten themselves out and get on the right track,
00:09:07
for somebody like Dawson it has no affect at all, just serves as an irritant for him,
00:09:12
just makes him angry because he wants to do what he wants to do; that's who he is.
00:09:18
- NARRATOR: By the age of 18, Andrew Dawson was already a veteran thief and his time in the youth prison,
00:09:25
nickname Borstal, had not curbed his criminal ways. But in August 1981, his life of petty crime
00:09:32
would take an even darker turn. - CLIFFORD: Henry Walsh had been a shopkeeper in the town for a long time, [unintelligible].
00:09:40
His shop didn't carry a lot of stuff, but it was stuff you couldn't find anywhere else,
00:09:45
it was sort of a--a time warp in some ways. He was just a loveable old character.
00:09:52
- NARRATOR: At some point, late on Thursday, the 13th of August, Andrew Dawson entered
00:09:58
Henry Walsh's shop, by the following morning, locals were concerned for the whereabouts of the 91-year-old.
00:10:06
- CLIFFORD: Mr. Walsh hadn't been seen on the Friday, which was unusual and somebody was going past,
00:10:14
noticed that two big, uh, gates which guarded the alley to the rear of the premises, they hadn't been closed
00:10:21
all night and his back door was open, which was unusual. - NARRATOR: The passerby dialed 999 and in a matter
00:10:28
of moments, Detective Jim Kay arrived at the scene. - JIM: I was driving through the town,
00:10:36
and the call came over the radio that this back door of the shop was open and there was no sign of the shopkeeper.
00:10:44
So, I just turned around the corner, it was a matter of 20 yards, and, uh, went into the shop
00:10:52
and another officer arrived. He arrived and I said, "Just follow me in." You're walking through expecting to find the old man
00:11:00
somewhere, maybe collapsed, to see this man hung on the door... It was a little bit frightening.
00:11:10
- NARRATOR: 91-year-old, Henry Walsh had been hung from coat hooks on the back of the door, tortured,
00:11:16
and then brutally stabbed to death with a carving knife. It wouldn't be long before news of the beloved elderly man
00:11:23
found viciously murdered in his own hardware store got out. It would send shockwaves across the quiet town
00:11:31
of Ormskirk, England. - CLIFFORD: I was in Moore street, uh, which is one of the main shopping streets
00:11:39
and about 250 yards away, at the other end of Moore street, I could see some unusual police activity.
00:11:46
I could see a policeman standing where a policeman wouldn't normally stand, and he wasn't moving,
00:11:51
so he was obviously guarding something, so I just acted on my reporter instinct that something was wrong,
00:11:58
and so, and so I got there and sort of based on the crime and ascertained that there had been a suspicious death,
00:12:06
and it was Mr. Walsh, so I arranged for a photographer to come out and take a picture that we used in the paper
00:12:14
of the police on the scene outside the shop. - Henry Walsh was a nice man. You know, one who spoke to every time I passed.
00:12:23
He would come to the door and say, "Good afternoon," and "Good morning," and very pleasant old man.
00:12:29
- He was just a really loveable person, and you just couldn't imagine anybody who would have it
00:12:36
in them to--to kill him, to be honest. - NARRATOR: News of the 91-year-old's horrific death began reaching the locals.
00:12:44
The nature of the crime was unthinkable. - CLIFFORD: He'd been stabbed with a knife,
00:12:50
been stabbed in the chest several times, but he'd also been hung up at the back of the door on some coat hooks,
00:12:58
and the last wound, the knife had gone straight through him and embedded itself in the back of the door.
00:13:05
He'd also tied a ligature around his neck presumably as a way to try and force information out of him.
00:13:12
- NARRATOR: The police didn't know it yet, but the killer was an 18-year-old thief
00:13:17
named Andrew Dawson, who had seemingly reveled in his first murder. - Dawson didn't just simply kill Henry Walsh,
00:13:26
he made this victim suffer. He stabbed him multiple times, some of the wounds were quite shallow, which is indicative of a torture,
00:13:35
of saying actually, "I have power over you, I am in control," and enjoying the reaction
00:13:41
of his victim to that. And he hung Henry up on the--the back of a door, so he's displaying his victim.
00:13:48
He's saying, "Hey, everybody, look at what I've done, look at what I can accomplish."
00:13:53
- GEOFFREY: You have to ask yourself, what is it that provokes an 18-year-old to kill him,
00:13:59
to repeatedly stab him, to pose him, and to leave him? There is something very, very depraved about that,
00:14:07
there is something monstrous. - LOUIS: I don't see him targeting a truck driver,
00:14:12
a 25-year-old truck driver out there, well, why isn't he targeting that guy. That guy can have money too, he just made his deliveries.
00:14:19
No, Dawson's way too smart for that, he targets somebody old and weak and vulnerable that he knows
00:14:26
he can get over on; that's who Dawson is. - NARRATOR: Dawson had killed a man 73 years his senior
00:14:34
for nothing more than the day's takings from the till, and the 91-year-old's pension book.
00:14:42
- When police conducted a search of the house later on, they found out that Mr. Walsh
00:14:47
did what most old people in those days did, and he'd hidden money in and around rooms
00:14:52
in the house, and I think they collected about £1800, uh, in cash, which is, you know, quite a lot of money
00:14:59
in those days, but I think Andrew Dawson had tried to get him to say where it was, but, uh, he refused,
00:15:07
which, I think perhaps it counts for the ferocity of his attack in the end. - JIM: He'd been frightened to death.
00:15:14
He was a very timid old man; not the type of man who'd look for trouble or get involved in trouble.
00:15:21
He's only picked on because he was an old man. He wouldn't fight back, I wouldn't have thought.
00:15:27
- NARRATOR: After taking the life of another man for the very first time, Dawson didn't panic
00:15:33
or attempt to flee Ormskirk, instead the cocky 18-year-old flaunted his newly acquired riches.
00:15:42
- Now, everybody knows he's got no money, you know, he goes to a pub, local pub where he's seen,
00:15:49
all of a sudden, feeding lots of coins into the fruit machine. Well, that's--that's rather odd, rather strange.
00:15:58
You're immediately going to say, "Where did you get the money from," it is unbelievably foolish.
00:16:04
- DR. YARDLEY: He was somebody who was perpetually broke, so this was something that was rather unusual
00:16:11
and that the police eventually catch up with him, and it emerged that Dawson had actually cashed in
00:16:17
Henry's pension book for £50 in the days following the murder. - CLIFFORD: Once Andrew Dawson was arrested, sort of, people,
00:16:26
in some ways they--they weren't surprised because they knew he did have a reputation, but who--
00:16:30
it was sort of shocked that he could have done such a--a savage act. - NARRATOR: At Preston Crown Court,
00:16:37
on the 10th of March, 1982, Andrew Dawson pleased guilty to the murder of Henry Walsh.
00:16:45
He had told police that he panicked after the 91-year-old had recognized him. In a statement, Dawson said, "I am sorry
00:16:54
"for what I have done, I had no intention "to cause anybody any harm. I wish it was me and not him."
00:17:03
- The judge at the Crown Court gave credence to Andrew Dawson's guilty plea and also to the fact
00:17:09
that, uh, he seemed remorseful to some extent. He was said to have told the police, you know,
00:17:18
"I wish it'd been me, not him," so the judge did give credence and mention this when she was passing sentence.
00:17:25
- DR. YARDLEY: I'm not convinced by this, whatsoever, we got to remember that this was a young man
00:17:30
who'd done a stint in Borstal, um, he was quite familiar with the types of things that he needed to say
00:17:37
to get sympathy, to get attention and to secure the best outcome for himself. - NARRATOR: Dawson, aged just 19-years-old
00:17:44
was jailed for life. He had graduated from Borstal to prison adding murder to his rap sheet.
00:17:53
- CLIFFORD: The murder-- from a murder trial, it's not exactly, when we said people
00:17:57
would love that sentence being carried out, we thought, Well, what I relief that, you know, some justice
00:18:02
had seem to be done and sort of the fact that the right thing had--had happened and people were now happy and so they were content
00:18:11
that the wrongdoing had been punished. - NARRATOR: Dawson spent the next 17 years of his life
00:18:16
behind bars, but during his time inside, he was no shrinking violet. He reportedly commented on serial killers
00:18:24
Peter Sutcliffe and Dennis Nelson, labeling them as wimps and claiming to be a better man.
00:18:32
- When he was in prison, he was comparing himself to other notorious offenders; that's a bad sign.
00:18:40
Anytime an offender wants to compare himself to other notorious killers, that's a huge red flag.
00:18:48
A sign of rehabilitation is, you wanna put that part of your life away, you wanna show
00:18:53
how you're different than other people, not how that you're more extraordinary than some of these
00:18:58
notorious people, that's a huge red flag. - NARRATOR: In early 1999, Andrew Dawson was deemed
00:19:05
ready for release from Sudbury prison in Derbyshire. Still, just 36-years-old, it was a chance for him
00:19:13
to start a new life. - After his release from prison, Andrew Dawson appeared to have turned over a new leaf.
00:19:20
He'd moved to a different area, Derby. He'd met a woman, he'd settled down with her
00:19:26
and they had two children together, and from the outside, he appears to be a regular guy,
00:19:32
but this was not to last because Andrew Dawson is a person who is prone to boredom,
00:19:38
he has that need for stimulation, he has that hedonistic streak to him, so he starts drinking and that leads
00:19:44
to the--the breakdown of his marriage. - LOUIS: He's matured now, he's older, maybe he's a different person, but it wasn't long
00:19:55
before Dawson reverted to who he was. - NARRATOR: Over the next decade Dawson would continually breach
00:20:02
the conditions of his release. - GEOFFREY: In that period between his divorce in 2003
00:20:08
and 2010, Dawson bumps into the law, and is returned to prison on a regular basis, three times.
00:20:17
He's drunk and disorderly, he's violent, he isn't in any kind of control and he's constantly
00:20:22
therefore--because he's out on license for the original life sentence-- straight back to jail,
00:20:29
almost as inevitably as night follows day, Dawson was going to kill again. It was only a question of when.
00:20:41
- NARRATOR: By July 2010, Andrew Dawson was estranged from his wife with limited access to his children.
00:20:49
He lived alone in a one-bedroom flat on Waterford Drive just outside of Derby. Former detective Paul Callum worked on the investigation
00:21:00
into the sudden death of one of Dawson's neighbors, 66-year-old, John David Matthews.
00:21:07
- The initial police incident came in at 7:00PM on the Sunday the 25th of July. Mr. Matthews worked at a local restaurant
00:21:14
and staff at the restaurant had been worried that he had not turned up for work in the previous week or so,
00:21:19
and, uh, police officers were called to the flat and they forced entry and they found, um,
00:21:24
Mr. Matthews' body in the bath downstairs. They looked at Mr. Matthews' body and; unfortunately, because they think
00:21:30
he'd been there for a couple weeks, there was quite a lot of decomposition, and at that time, uh, the incidence was recorded
00:21:37
as a potential suicide. - NARRATOR: But the postmortem told a different story. - DET. CALLUM: Late in the afternoon of Wednesday,
00:21:46
the 28th of July, I had a phone call from the coroner's office to say that the local
00:21:51
pathologist had started the postmortem of Mr. Matthews and that he said that there was,
00:21:56
uh, what he believed were stab wounds. - NARRATOR: It was clear, this was not a suicide;
00:22:01
it was, in fact, murder. The killer had done his best to cover up the murder. - DET. CALLUM: What he'd done at the crime scene
00:22:09
with Mr. Matthews is that, uh, after stabbing him, he'd re-dressed him, so he got rid of the shirt
00:22:16
that had the stab wounds through it and put a shirt that didn't have any marks on it.
00:22:20
And completely changed all his clothing and then put him into the bath. We started doing some early inquiries
00:22:26
and one of those which, you know, what--what do we have on the, uh, electro register? Who lives there?
00:22:31
What intelligence do we have around the block of flats? - NARRATOR: Detectives immediately singled out
00:22:36
convicted killer, Andrew Dawson as a potential suspect. - DET. CALLUM: It very quickly became obvious
00:22:42
that Andrew Dawson was gonna be our suspect. He had a conviction for murder, um, and he was on license
00:22:50
and there was some history of a recent assault with, um, somebody else at a previous flat that he'd lived at, um,
00:22:55
so, it was reasonably obvious that he was gonna be our main focus quite early on.
00:23:01
- We wanted to secure the scene at-at Dawson's house and then, obviously our biggest priority
00:23:06
was finding out where was Dawson right now. - NARRATOR: Whilst detectives launched a manhunt,
00:23:12
investigators forced entry into Dawson's flat. - The flat was completely empty, um, apart from a few
00:23:19
items of clothing, but what was particularly interesting about Dawson's flat was that it smelled of bleach
00:23:23
and it was very, very clean. - NARRATOR: Andrew Dawson was no where to be found.
00:23:29
He was on the run and presumed to be very dangerous. - DET. CALLUM: We were extremely worried,
00:23:36
we obviously knew that a murder had happened at some point before the Sunday the 25th,
00:23:40
and--and looking at the decomposition, we think probably up to two weeks before that,
00:23:44
so we had nearly a three week time period where we had no idea where Dawson had been.
00:23:49
- NARRATOR: John David Matthews, who was known as Dave, had actually been killed on the 10th of July,
00:23:56
stabbed 18 times by his seemingly friendly neighbor, Andrew Dawson, who often popped over to use the washing machine.
00:24:06
- GEOFFREY: Dawson arrives at his door with the conventional excuse that he used many times
00:24:12
in the block, "Can I use your washing machine? Because mine's broken," Dave lets him in, not suspecting anything.
00:24:21
- Imagine what must have gone through Dave Matthews' mind. It would've been indescribable.
00:24:29
Terrifying. Reduced him to absolute fear in an instant and yet there was nothing he could do, nothing he could do
00:24:39
to protect himself against a man who'd come there to kill him, and to kill him for reason entirely of his own.
00:24:45
This was not a motive of greed, this was a motive of the desire to kill. - DR. YARDLEY: After Dawson had killed David
00:24:52
and left his body in the bath, he actually left the flat, um, because this was the day when he was looking after
00:24:59
his children and he took them out for the day as if nothing had ever happened and he returned the next day and cleaned up the crime scene
00:25:09
and got rid of the blood. Now for somebody to be able to do this, to be able to function as normal after committing a murder,
00:25:16
is something that is very, very rare. I've met a lot of people convicted of murder
00:25:21
and their behavior in the aftermath is very rarely normal because they're so shocked
00:25:27
at the enormity of what they've done that they're unable to function with any degree of normality.
00:25:33
- NARRATOR: The crime had affected the whole community. As the search for the convicted killer continued,
00:25:41
detectives question the other neighbors at Waterford Drive. One neighbor even told the story to police
00:25:48
of how the killer had been involved in an altercation in his flat. - A resident started telling
00:25:54
the investigating officer that had sat down with him to take his statement, about, uh, the relationship
00:25:58
with Dawson and that they use to walk into each other's flats and this sort of thing.
00:26:02
- NARRATOR: The neighbor went on to describe an incident which had occurred just days before.
00:26:08
After inviting Dawson in for a drink, he caught him riffling through his drawers.
00:26:13
The neighbor confronted him and Dawson turned nasty. - He was grabbed from behind with an arm
00:26:19
around his neck and he felt something in his, uh, in his sort of lower abdomen. He'd sort of thrown Dawson off.
00:26:26
Dawson made light of it, and said he was just mucking around and this sort of thing,
00:26:29
and--and again at the time, he didn't particularly think anything of this, but we now know
00:26:33
when you listen to the account, uh, and you know what Dawson was capable of, that it was likely
00:26:39
that he was gonna be his first victim. - I think that's only further evidence of the fact
00:26:44
that in this small block in Chaddesden, not alot of flats, that Dawson, by now, was out of control,
00:26:52
completely and utterly out of control. He would attack anyone, driven by his own desire to kill.
00:27:00
- NARRATOR: On the morning of the 30th of July, detectives receive news that Dawson had been spotted
00:27:06
in Whitehaven, Cumbria over 200 miles away from Derby. While local police begin to search for the killer,
00:27:16
investigations were continuing at the flats. Detectives had accounted for all of Dawson's neighbors apart from one,
00:27:25
58-year-old Paul Hancock. - DET. CALLUM: So about half past seven or eight o'clock
00:27:30
while I was doing the briefing, we got to one of the detective sergeants stood at the back
00:27:34
of the--the room and was waving at me, and she came across and whispered to me and said,
00:27:38
"They found another body," and that the officers that were doing the house to house inquiries
00:27:42
had forced entry into Mr. Hancock's flat and had found him and he'd also been murdered.
00:27:47
We finished the briefing and it started again, and this is when you started to really feel concern that,
00:27:52
what had Dawson been doing in that three-week period when the-- we couldn't account for him,
00:27:56
and had he killed anybody else? - NARRATOR: How many more bodies might turn up at Waterford Drive?
00:28:03
It was a frightening thought for the investigators, and they soon had information that revealed the killer
00:28:09
had been in the building on the very same day the body of Dave Matthews was discovered.
00:28:15
- DET. CALLUM: It turns out on the Sunday afternoon, the call came in about Mr. Matthews,
00:28:20
the police had arrived at the flat and, uh, this came out with subsequent inquiries,
00:28:25
but it turned out that Dawson was actually upstairs in Hancock's flat when the police arrived.
00:28:31
Now, it's possible that he'd just committed the murder, at that point, or he may have committed the murder
00:28:36
over the previous few days and he was there cleaning, starting to clean up, we--we will never really know,
00:28:41
but what we do know is that Dawson was in Mr. Hancock's flat when the police arrived.
00:28:46
He came downstairs, he spoke to one of the special constables that was there and he was asked had he seen Mr. Matthews,
00:28:52
and he spoke to the police and said that, oh, no, he doesn't know him very well, he hasn't seem very much of him,
00:28:56
and we then know that within about 10 minutes he'd packed his bag, he'd ordered a taxi
00:29:00
and he'd left the house and had gone to the train station. - NARRATOR: Unbeknownst to the police,
00:29:06
they had stood face to face with the killer. Since that moment, Andrew Dawson had been on the run
00:29:13
for five days, but now, local police in Whitehaven had located him and were ready to make an arrest.
00:29:23
- The uniformed constable comes across Andrew Dawson sleeping on a bench on the sea front
00:29:31
in Whitehaven. He might almost have had a sign on chest saying, "I am Andrew Dawson and you really want to
00:29:37
look at me because I killed two people in Derby." - NARRATOR: But the police had to proceed with care.
00:29:44
They were dealing with a serial killer. Armed with seven knives in his backpack,
00:29:49
Dawson had no intention of giving himself up. - Dawson appeared to want the police to shoot him.
00:29:57
He wanted to go down in a blaze of glory and basically occupy alot of headlines.
00:30:02
There's a real kind of dramatic element to this perpetrator, and shortly after he was arrested,
00:30:09
he jumped into the sea and he started to swim away and it really is quite incredible,
00:30:16
the behavior of this man. He soon realized, "Actually, this probably isn't a good idea,
00:30:21
I'm not getting anywhere," and then swam back to shore where the police caught up with him again.
00:30:27
It's an attempt at being dramatic, it's an attempt at--at trying to create this kind of
00:30:33
feared persona, but it's one that always falls flat on it's face for Dawson. - Dawson is tazored rather than shot.
00:30:41
I'm sure he was very upset by that. I'm sure he'd much rather that armed response unit
00:30:46
had turned up and, uh, given him the glory that he'd wanted. - NARRATOR: With Dawson safely in custody,
00:30:53
investigators could begin to delve deeper into the 47-year-old killer. After his dramatic arrest
00:31:00
in Whitehaven, Cumbria, he'd been brought back down to Derbyshire to be questioned on suspicion of the murders
00:31:06
of his neighbors, Dave Matthews and Paul Hancock. The bodies of both victims had been bathed in bleach
00:31:13
to hide any forensic evidence. Detectives would have to use all their skills to prove that Andrew Dawson had killed again.
00:31:23
- DET. CALLUM: In terms of an investigation, normally you have some 36 hours of real, uh, urgent work to do
00:31:30
because you have to either have to get enough evidence to charge somebody or you have to release them,
00:31:34
uh, because he was on parole and because of the nature of this, uh, actually from an investigators point of view,
00:31:39
it made the job a little bit easier because we could recourt him to prison and actually we had a lot of time
00:31:45
to make sure that we could, uh, get the evidence together and get the case together, which was just as well
00:31:50
because despite it feeling like it was obviously him, you've got to get the evidence to prove that
00:31:55
and forensically, it was very, very challenging. - NARRATOR: On the same day of Dawson's arrest,
00:32:01
police had discovered the body of 58-year-old Paul Hancock. Just like his neighbor, Dave Matthews,
00:32:07
Paul had been found stabbed to death in his own bathtub. - With Mr. Matthews the flat had been cleaned,
00:32:14
there was alot of bleach poured into the bath, it clearly been tidied up and with Mr. Hancock's,
00:32:21
it was very disheveled, it had been very rushed. There was clothing in the bath, there was weapons in the bath,
00:32:27
there were all sorts- bits of gloves, marigold gloves and this sort of thing. All the drawers had been through the house
00:32:32
and we know that money was stolen and--and various other items, and apart from the fact
00:32:37
that there was bodies in the bath and they'd been stabbed, the two scenes were totally different.
00:32:42
- NARRATOR: It's believed that Dawson was still cleaning up the crime scene when the police had discovered
00:32:47
the body of Dave Matthews across the hall. Dawson likely panicked and threw his clothes
00:32:54
in the bath of bleach to kill any forensic evidence. - DET. CALLUM: On the yellow trousers he was wearing,
00:32:59
there was a slash mark on the right hand side, on the right leg. Dawson also had, uh, an injury to his right leg
00:33:06
and it's impossible to actually match that to the injury but again it's very likely that he was wearing
00:33:10
those trousers when he committed the murder, so he was very forensically aware, so I think he had a system.
00:33:16
He had a type of clothing that he wore to make sure that he doesn't get contaminated with blood,
00:33:21
and then he went and--and commits the murders and then he--he bleaches them and gets rid of any evidence.
00:33:28
- LOUIS: Bleach indicates forensic awareness. Bleach is one of those things that wipes up a great deal
00:33:34
of forensic evidence. Dawson's been a career criminal. He's been in prison his entire life.
00:33:41
He knows what bleach does. He was in the juvenile center, but he also went to state prison, that's like graduate school for crime.
00:33:48
All the criminals do all day is talk about their crimes and how they got caught and this and that,
00:33:53
and how to avoid law enforcement, so the fact that he used bleach doesn't surprise me at all,
00:33:59
it just reflects what he learned in prison and how to try to avoid detection. - NARRATOR: With Dawson being held in custody indefinitely,
00:34:08
it gave detectives more time to study the crime scene at Dave Matthews' flat. - When we first searched Mr. Matthews' house,
00:34:18
there was few, uh, items that we didn't really understand. One of them was a rose that was on, uh, pillow
00:34:24
in Mr. Matthews' bedroom, and it was just an old red rose. The other thing was, when we searched Dawson's flat,
00:34:31
there was a blank notepad, um, but you could see indentations on it. - NARRATOR: This suggested that a note had been written
00:34:39
on the sheet of paper above. If experts could decipher the faint indentations it could be a huge clue.
00:34:47
- DET. CALLUM: About three weeks after that inquiry had--had been sent off, I got a phone call from,
00:34:52
uh, our forensic team, really excited and they said, you know, they were saying, "Boss, this is amazing,
00:34:57
this is fantastic, we've got a confession," and I said, "What are you talking about?"
00:35:02
And it turned out that he'd written a letter to the police and it was to the--to the head of homicide,
00:35:08
it said, and he wrote this poem, a very badly spelled, but the poem talked about, in a bath,
00:35:14
uh, in--in Waterford Drive there lies a man, and he talked about if in two weeks time
00:35:21
you don't know about it, I will come and report it to the police, and he talked about the rose
00:35:26
being the, a nice touch and he signed it "The Angel of Mercy." - DET. CALLUM: Really, really chilling,
00:35:33
but very, very important key bit of evidence. - NARRATOR: Dawson had signed the note
00:35:39
with a chilling moniker. - DR. YARDLEY: The confession letter that police had come across
00:35:45
had been signed "The Angel of Mercy," and I think this is really testament to Andrew Dawson's narcissism.
00:35:52
He wanted a brand, he wanted an identity, he wanted infamy, and I think this was very much part of that.
00:35:59
He wants that recognition for the things that he's done. - He's pretended to be significant, he's not,
00:36:06
he's an insignificant, horrid, horrible, depraved, monstrous killer, but not in his mind.
00:36:14
- NARRATOR: As investigations continued, more evidence was uncovered at Dave Matthews' flat.
00:36:20
- DET. CALLUM: In Mr. Matthews' house, there was very, very little forensic evidence in there,
00:36:25
in terms of fingerprints, DNA and this sort of thing. He had destroyed most of the evidence,
00:36:30
uh, but we found marigold glove in the bath that had the thumb missing on it, and part of the forensic strategy was to find
00:36:38
this piece of rubber from the thumb. - NARRATOR: Paul knew that finding the tip of the glove may finally yield some forensic evidence.
00:36:46
- So, the whole house was completely emptied, uh, we spent weeks there meticulously going through everything in the lounge
00:36:52
and--and the scene's crime team found the tip of the marigold glove and we think that it probably
00:36:59
got caught in a drawer while he was stealing property from the flat, and it snapped off,
00:37:03
and in this small piece of the thumb--and it was, it was the tiny piece of the thumb there--
00:37:09
um, they managed to recover some DNA which, uh, proved that it was Andrew Dawson, which was a very, very
00:37:15
significant piece of evidence because forensically we had very, very little. There was alot of circumstantial evidence
00:37:20
but little forensic evidence. - NARRATOR: In total, 5,000 items were seized from the flats at Waterford Drive;
00:37:27
however, only one of these provided the conclusive forensic evidence investigators needed.
00:37:34
This new discovery undoubtedly connected Dawson with the murder of Paul Hancock.
00:37:40
In interviews with investigators, Andrew Dawson initially confessed to both murders.
00:37:47
- He talked about Mr. Matthews being a nice man. He talked about how he didn't really want to kill him,
00:37:52
but he just felt that he had to and he had an urge to do it, and this was what's particularly chilling and very frightening
00:37:57
about Mr. Dawson. There didn't seem to be any particular motive other than I desire to kill somebody,
00:38:03
so in that respect, you know, you--you tell me someone's mental state, I mean that's, uh, that's quite worrying
00:38:10
and certainly, I mean, I've dealt with a lot murder inquiries, um, for all sorts
00:38:15
of different reasons but to have somebody that said they just had an urge to do it,
00:38:18
is very, very frightening. - NARRATOR: By the time of his court hearing in July 2011,
00:38:25
Dawson had changed his story, denying the murders and pleading not guilty, but he didn't hide behind
00:38:32
his lies for long. - DET. CALLUM: You saw it in court, he was very, very inpatient.
00:38:37
He--he didn't like to wait around, He's like a very impetuous sort of character.
00:38:40
For example, at court he pleaded not guilty and after a couple of hours, he--he looked like he got bored
00:38:45
and he had a word with his solicitor and just said, "Oh, I can't be bothered, I plead guilty,"
00:38:49
you know, and that was, that was the court case, and that was kind of the way I think he was.
00:38:54
- DR. YARDLEY: This is a tactic we see with alot of offenders like Dawson. They enjoy playing with people, they enjoy manipulating people.
00:39:00
They enjoy having everybody running around sorting things out and then they chuck a grenade in
00:39:05
and cause chaos and I think that's exactly what he was doing here. - NARRATOR: In total, Andrew Dawson stabbed
00:39:12
Dave Matthews 18 times and Paul Hancock 22 times. He had received a fairly lenient sentence after his first murder
00:39:21
in Ormskirk in 1981, but there would be no similar result for him this time. - The judge, Mrs. Justice Dobbs, gave Dawson
00:39:32
a whole life tariff, "Life will mean life in your case." She told Dawson, in sentencing,
00:39:40
"These were premeditated and planned, brutal killings. "Each had the misfortune of being your neighbor
00:39:50
who had no chance." - DET. CALLUM: Relief, I think more than anything. There--there wasn't, you know, there's no particular reason
00:39:59
to sort of celebrate or anything like that, it's just, you know, really sad for the victims and the family.
00:40:04
These are both--both victims, uh, were just, you know, regular people that, uh, were tryn to live their life
00:40:12
and hadn't particularly upset anybody, for both had been described as very pleasant people
00:40:16
who had just sort of kept themselves to themselves, so very, very sad. - NARRATOR: Andrew Dawson remains in prison
00:40:23
and will never be released. Some experts believe that he was never rehabilitated
00:40:29
after his first murder conviction and should have never been in a position to be able to kill two more innocent victims.
00:40:38
- For me, what makes this case exceptional is the failure to realize how serious the first murder was.
00:40:44
It was interpreted as a homicide during the course of a robbery, but actually it was much, much worse than that.
00:40:51
This individual had been tortured, essentially, that the time that the perpetrator had spent
00:40:56
with the victim was quite significant, and the perpetrator was only 18 years old,
00:41:01
so I think this was, uh, a massive red flag for--for further potential violence and even though
00:41:07
he was convicted of murder, there was not enough work done to address what led to that.
00:41:13
- CLIFFORD: I think there--there is a case that sorta some people are so dangerous that they
00:41:17
can't be let out again, out of prison. It seems a harsh thing to condemn somebody
00:41:21
to die in prison, but sort of-- I think some people, you know, never learn and never alter.
00:41:26
I think it's one of those things that sort of sometimes you--you have to do it, and, uh, this is, you know,
00:41:32
probably one of those cases. - NARRATOR: Dawson was a selfish killer who had no regard for his victims.
00:41:39
The only reason he's ever given for his horrific crimes is that he had an urge to kill.
00:41:45
- When we look at the crimes of Andrew Dawson, they are so horrendous that many people say
00:41:49
this could only be the workings of a madman, but unfortunately, they're not, this is an individual who knew
00:41:57
exactly what they were doing. They knew that what they were doing was wrong and they carried on doing it anyway.
00:42:03
- GEOFFREY: It's conventional to talk about serial killers as having a trigger, sometimes it's in their childhood,
00:42:10
sometimes it's a moment in their adolescence. I don't believe there was such a trigger to Andrew Dawson,
00:42:16
I think there was something in him from the very beginning that led him to commit these heinous crimes.
00:42:24
- DET. CALLUM: I've dealt with alot of suspicious deaths and a lot of murder inquiries, and there weren't many
00:42:28
that's kept me awake at night, this guy kept me awake at night because you just had this feeling that you had
00:42:33
to get the evidence, you had to put him away because he was an absolute danger to anybody in society.
00:42:38
I think this idea that you can suddenly, um, get an urge to kill someone clearly makes you
00:42:43
extremely dangerous, doesn't it? - NARRATOR: Dawson is a killer who murdered innocent people
00:42:48
for his own depraved enjoyment. He may have started out as a petty thief, but that was an unlawful livelihood that didn't satiate
00:42:57
his urges, he needed something more to satisfy his twisted mind. His lust for murder and the pleasure
00:43:04
he gets from it, are what makes Andrew Dawson one of the world's most evil killers.
