00:00It's 10.30 in the morning, a sunny day.
00:30Wimbledon Common is busy with dog walkers, lots of men, women and children.
00:41Hundreds of people use Wimbledon Common every day. Women went there jogging and
00:46walking. It was thought to be entirely safe.
00:50Emergency, which service do you require? A man out walking with his dog sees the
00:59naked body of a young woman. She'd been walking her little boy on Wimbledon
01:05Common and he was found clinging to her body crying, wake up mummy, wake up mummy.
01:10She was covered in blood. The only thing that he felt in his little mind that he
01:16could do to help his mother was to try and staunch her bleeding. He was only two
01:22years and a few months. He has placed a till receipt on her forehead as a make-do
01:32bandage. He's clearly distraught, he's asking for his mummy to get out but
01:39unfortunately that can't be the case because she's dead.
01:47The Rachel Nickell case just hit the headlines. I don't think I'll ever forget
01:54the image of her that was circulated at the time. Beautiful young woman with all
02:01her future ahead of her. For somebody to have the gall to do something like that
02:07in broad daylight and in front of a child is shocking. Many people must be
02:13asking is anyone safe when murders can take place in broad daylight? The crime
02:18was so horrendous it began to herald in a whole new era of fear. Police sought to
02:25dispel fears about sex attacks on women in open spaces like Wimbledon Common. He
02:30needs to be stopped before women felt safe again. I can honestly tell you that
02:35this is the most horrendous and vicious attack that I've ever seen. The acquire
02:41that was launched was one of the biggest since the Yorkshire Ripper. Millions of
02:47pounds were spent trying to capture this man. No stone was left unturned.
02:54Despite this no one was convicted for the murder of Rachel Nickell for another
02:5916 years. Most people remember the murder of Rachel Nickell on Wimbledon
03:06Common however what a lot of people don't realize the perpetrator could have
03:10been caught earlier. This killer could have been apprehended if only there
03:14hadn't been a catalogue of tragic missed opportunities. Could there have been
03:20serious offenses stopped for want of a better word and I think the answer to that is yes.
03:28To understand how it was that Rachel Nickell's killer was free to commit a
03:44whole chain of atrocities we need to go back to 1989. Still into the mid-twenties
03:53today across the region with some light winds going into the afternoon. There's a
03:58chance of a few light showers later this evening moving through the region
04:01but with high temperatures remaining. There was a young mother at home with
04:06her children. The children were having breakfast. It's going to be quite a muggy
04:10night with humid temperatures down to around 14 degrees in the region. When a
04:15man entered via the rear door
04:19he was armed with a backhandled Stanley knife. He threatened the mother saying
04:27that if she didn't comply she would endanger the children. The mother's
04:32natural instinct would of course be to protect her children beyond anything
04:37else. He made her kneel on the bed pull her t-shirt over her head and then he
04:46raped her. He then left saying that you should really make sure you lock your
04:55back door. It's almost like he's saying she's responsible.
05:04The woman immediately contacted the police and she was very brave to allow
05:10herself to be examined. To come forward as a woman and be examined and tell your
05:23story and go through it all again is difficult. It's very very difficult. The
05:29forensic officers were able to recover DNA but we had nothing to compare it
05:35against. DNA profiling back then isn't like it is now. There wouldn't have been
05:41a DNA database like there is today. They weren't even on computer so it's
05:47completely different now. It's so much easier and so much quicker to match
05:51somebody if they're on the system and they've been previously arrested. In 1989
05:56it required police to catch the individual and do a match to that
06:03individual.
06:09That incident happened in South East London near Winds Common. That bit of
06:15parkland is dissected by a road and then you have Plumstead Common on the
06:21other side of that road. The commons of Plumstead and Winds Common form part of
06:27what they call the Green Chain Walk. Over the next two or three years there were a
06:33number of very nasty attacks on women on the Green Chain which was a series of
06:38parks and open spaces linked by footpaths popular with dog walkers and
06:43joggers and people out for a stroll. It's places people can go for a nice
06:47country walk where you're not in a built-up area and it's a nice relaxing
06:54place to go and walk. And of course it's an ideal hunting ground if you're a
07:01potential rapist. At the time I was living around South East London I was
07:08late teens early 20s. My dad was telling me you don't go near the Green Chain
07:13walks without somebody being with you because of what was going on. Makes you
07:18feel very very uneasy. Everybody needs to look after each other so you need to
07:22keep an eye on other people and if the worst things happen you need to try and
07:27attract attention to yourself. Shout and scream, kick your shoes off and run away.
07:31Back then you didn't have mobile phones. The only thing you could rely on is if
07:35you had a panic alarm or what we used to call back then we used to call them
07:39rape alarms and if it's dark I'd have your keys between your fingers or you
07:45make sure you've got something with you for safety.
07:52Back in 1989 we were really something in the dark ages in terms of what the
07:59police could do. There was hardly any CCTV so the man responsible was able
08:06unfortunately to carry on and attack other women.
08:18We didn't think it was just one man who was responsible for all those attacks
08:24but in March 1992 that changed.
08:29In 1992 in South London near Lewisham a teenager a 17 year old was getting off
08:57the bus it was evening and she notices a man following her. We are so aware as
09:08women who's behind us if there's a guy walking a bit too close behind you it's
09:14very unnerving. He was following her and then he disappeared and then he
09:23reappeared in front of her and he produced a knife. He made her undress and
09:32tried to rape her and then he punched her in the face very hard.
09:43The young lady obviously feared for her life. She eventually runs to a friend's
09:52house and does report the attack to police and they are able to take DNA
09:59evidence. The DNA taken from the 17 year old girl could be compared to the 1989
10:11offence near Plumstead. It revealed that it was the same individual.
10:19This was a light bulb moment for the police because they suddenly realised
10:23that the 1989 incident had not been a one-off and the 1992 incident was not a
10:29one-off. These were linked offences and there was a probability that with a gap
10:35of three years there have been other offences where they hadn't been able to
10:38recover forensic evidence and so they began to look at other crimes that had
10:42been reported. They realised then that they had a serial attacker on their
10:48hands.
10:51The individual has now escalated the level of violence against his victims.
10:57It's an unnecessary physical assault on the young woman which would then indicate
11:03that he probably enjoys inflicting pain onto his victims and in all likelihood
11:13he will continue to escalate.
11:20It's now obviously extremely important that this man is arrested as soon as
11:27possible.
11:34Operation Eccleston was formed. A team of officers whose sole job was to try and
11:42track this man down and put him in jail where obviously he belonged. But the
11:51police have no one to go on. The descriptions were poor. Obviously events
11:59were traumatic. We had a description of a white male, medium build, height around
12:08five foot eight. The advice is to try and remember as much as you can
12:15about somebody but if you were being attacked by someone your first thing is
12:19self-preservation. To have the height of somebody they're not standing up in
12:24front of you nicely and straight. So it's a guess.
12:31The Eccleston team have an artist's impression of the green chain rapist
12:36based on the information given from the actual victims themselves. That
12:42circulation they would hope would then lead to someone known to the culprit
12:50coming forward and making an identification. Unfortunately that
12:55didn't work. Let's have a reality check here. You've got a rape inquiry team you
13:02talk about 10-15 officers of that. If you'd thrown a team of say 50 detectives
13:08onto the green chain rapist series I'm sure he would have been arrested much
13:13much quicker. But the harsh reality is that's not how it was.
13:22In a fairly short space of time another attack happened. Both these attacks took
13:28place you know late in the evening. But in May 1992 there was a complete
13:35departure from this pattern of crime.
13:43A woman was walking along a footpath in a parkland area. It's 2 p.m. in the
14:04afternoon. And she has her child with her in a buggy. Why would she think in broad
14:15daylight that she would be at any risk? She was aware of a man following her who
14:25disappeared and and then suddenly he wrapped some form of ligature around her
14:31neck and pulled her to the ground. He punches her several times very hard and
14:37he rapes her.
14:42It's very unusual for someone to attack a young mom out with a pram in broad
14:49daylight. He must know the threat of attack on the child will ensure
14:54compliance. DNA linked that attack to the green chain rape series. She was able
15:06to give a description of a man around a six foot mark which was of course very
15:11different. The other victims were giving a height range of a man who was five foot
15:15seven five foot eight. This becomes quite a crucial part of the case in terms of
15:23the police investigation and the focus on the height of the assailant. Sometime
15:32later the woman changed the description to a shorter man. She gave a height
15:38around the five seven five foot eight bearing mind that she's been badly
15:42beaten up. A member of her family was unable to recognize her. She was in such
15:48a you know bad way. They told the police that they were dealing with a very
15:53dangerous man. I mean if he was prepared to do that to a woman in front of a
15:58child what else was he prepared to do? Fast forward a few months you have the
16:05Wimbledon common slaying of Rachel Nickell.
16:18It was very traumatic, very unusual. I had certainly no memory of anything like
16:29that happening in the UK. Murdered in broad daylight a woman is stabbed and
16:34her son attacks. The attack happened in a secluded part of Wimbledon common in
16:39broad daylight. A man out walking his dog came across a woman he believed was
16:43sunbathing. It was difficult not to hear about the murder of Rachel Nickell. It's
16:47such a high-profile case it was on all of the news channels. Police are hunting
16:51for a man who murdered a young woman and attacked her two-year-old son while
16:55they were walking on Wimbledon common this morning. She was sexually assaulted
16:58and her throat had been cut. When you have a crime like this it does bring
17:02everybody up short and everybody thinks oh maybe that could have been me there
17:05but for the grace of God. You think you're going to be safe in broad daylight
17:08right in the open like that. The level of publicity does create an enormous amount
17:16of pressure to arrest the culprit. It is very trying very very challenging. There
17:25was a huge police response to this crime. I think you know from Land's End to
17:32John O'Groats people were saying I'm not going out on my own while this killer is
17:36out there. No stone was going to be left unturned to try and identify and arrest
17:44this individual. The body of the victim is generally the main source of evidence.
17:53Adhesive tapings are placed on the body and hopefully sticky adhesive then will
17:59lift skin cells, semen, saliva and fibers that may have been transposed by the
18:05culprit. Rachel's 49 stab wounds were created by a very sharp knife and the
18:15depth of those wounds would indicate that the knife was thrust inside the body so
18:19hard that the hilt left marks on the skin and so the individual who created
18:25those wounds clearly meant to kill. It was a frenzied attack by a very disturbed
18:33individual.
18:45Rachel's son Alex had been pushed face down into the mud at one point and
18:51dragged by his feet away from his mother and the crime scene manager had the
18:59presence of mind to comb the child's hair. The police recovered red material
19:08from his hair. It was identified as being paint. The crime scene manager at that
19:15time wouldn't have known the importance that would play sometime later.
19:23Alex clearly had had a look at the man he referred to as the bad man. We enlisted
19:34the help of child psychologists in order to obtain the best evidence from him.
19:40This is a two-year-old who's gone through an unbelievably traumatic
19:46experience. He was however able to get a man's description. He's seeing a white man
19:54with a white shirt. This does tie in with the other witnesses. One woman in
20:00particular recalled seeing a man who wore a white shirt. He was washing his
20:06hands by a stream nearby and she got a good look at his face. The woman
20:16described the man as possibly being flat-footed. He had an unusual gait. We
20:24examined that area and we found shoe marks in the mud plaster of Paris. Casts
20:31were taken off those marks in the hope that one day we would find a man who
20:37possessed such a pair of shoes and therefore link him back to the crime
20:42scene. All of these clues are of no use until we can actually lay hands on the
20:50man who killed Rachel Nickell. The police are desperate. They don't really have any
20:56leads. There's no forensic evidence that connects them with the killer.
21:04Around about this time there was an increased interest in the science of
21:10forensic psychology across all police circles. The police started to think that
21:17having a forensic psychologist on board that might be useful to solve the murder
21:22of Rachel Nickell. So one thing they did was to introduce a man called Paul
21:29Britton who was a forensic psychologist. They invited Paul Britton to tell them
21:34what kind of person they thought would have committed a crime of this horrendous
21:39nature. The profile that Paul Britton produced was that the suspect would be a
21:48white male. He would be in his 20s. He probably lived alone. He would work in a
21:58low-skilled job. Probably very shy. He probably didn't have a girlfriend. He
22:04wouldn't be able to have a sexual relationship and he was inadequate in
22:08that way. The man was a loner. He probably was interested in pornography. He would
22:13live locally and would know the area very well. It was decided to use the
22:23publicity surrounding the case to find the suspect. So the police contacted
22:29Crime Watch. Crime Watch UK started in 1984. It was a whole new concept in
22:37television because we were showing people real crimes and asking people if
22:42they could help. Nick Ross and I were the presenters. The hope of course of the
22:46program was to solve serious crimes that police hadn't been able to solve
22:51themselves. The first thing of course Crime Watch does is we reconstructed
22:56Rachel's walk across the common with her little boy and we showed a photo fit of
23:03a man who'd been seen in the area at the time.
23:07Some information was released from the profile provided by Paul Britton. It was
23:17a crime of such magnitude and everybody knew about it. Every single call, no matter
23:24how trivial it might seem, had to be checked and checked over and looked at.
23:28There may just be one call that will make the difference. Someone who will
23:35provide a name. Among the calls we had people who thought they recognized the
23:41the photo fit we'd shown and a name was mentioned and that name was Colin Stagg.
23:49Colin Stagg was a person of interest. They went to Colin's address. They found
23:56this individual who lived alone. During the search of his home it was noted by
24:02the officers that one of his bedrooms was painted black with various what
24:08they considered to be occult symbols on the walls which was unusual.
24:16There were certain things about Colin Stagg that did absolutely tally with
24:20Paul Britton's analysis. He had some pornographic type, girly magazines,
24:25a collection of knives. When they asked Colin Stagg if he could provide them
24:31with the shoes that he was wearing that day he told them that he'd thrown them
24:36away which was in police eyes a major red flag.
24:41Colin Stagg is arrested for questioning.
24:49When Colin was arrested but he answered every question and he agreed he'd been
24:53on the common that morning walking his dog Brandy but he'd left the common and
24:58when he woke up having recovered from a headache that he'd suffered he went back
25:02up to the common to discover that was closed because the murder had taken
25:06place. He had had a conversation with a uniformed PC and that police officer
25:11felt that he'd been acting suspiciously and had an unhealthy interest in what
25:19was going on. Is it that the killer will return to the scene of his crime or was
25:24it just the interest of somebody who why can't I go on the common where I normally
25:27take my dog?
25:32The forensic psychologist thought our murderer might well have committed other
25:37sexual offences. He may or may not have been caught for them but he thought
25:41that there'd be a history there somehow. During the course of the
25:46interview Colin offered up to the police the fact that he had on occasion sun
25:51bathed nude on Wimbledon Common and he felt someone might have seen him.
25:57A short time after Rachel was murdered a woman reported to the police she'd seen
26:01a man sort of lying on the grass and he indecently exposed himself to her.
26:06They supported the profile provided by Paul Britton as someone who would
26:12indulge in indecent exposure or similar offences.
26:21A light bulb goes on and they think aha look at the profile look at the profile
26:26this is this is our man this is this is where he's aging towards being our red
26:32hot suspect. Colin Stagg spent three days in police custody. At the end of the
26:38three days of interview the police are left with no physical evidence against
26:43Colin no blood evidence no DNA evidence no identification evidence all they have
26:49is this admission by him to sunbathing nude on the common they have nothing
26:54else against him at all. So in the end Stagg goes before local magistrates
27:01pleads guilty for indecent exposure. He gets a fine and as far as he's concerned
27:07he thinks that's the end of it.
27:11Of course once Colin has pleaded guilty at Wimbledon Magistrates Court to
27:15indecent exposure he's named and shamed it's in the newspaper. It was on the news
27:23that night him coming out of court looking angry and upset and so everybody
27:28that has seen him on the common thinks there is Colin Stagg convicted sex
27:34offender. A lot of people believe there's no smoke without fire.
27:42As far as the newspapers were concerned Colin Stagg was public enemy number one.
27:51The fallout from that is a woman contacts Scotland Yard and she says I've
27:56been looking for a partner so I've been putting some advertisements into a
27:59lonely hearts column. Lonely hearts columns where people would put an advert
28:04in the newspaper for looking for love and somebody has responded and this
28:09person is a chap who signs himself Colin Stagg. The letter he wrote to her was not
28:16an ordinary love letter this was highly sexually explicit. Of course at Scotland
28:26Yard their ears prick up and they say oh you know we really need to see those
28:29letters please. Part of the profile provided by Paul Britton had stated he
28:38would have extreme sexual fantasies. The letter added to the suspicion against
28:47Colin Stagg. Subsequently Colin received a letter from a woman calling herself
28:57Lizzie James who claimed to be a friend of the lady who Colin had the unwelcome
29:03correspondence with and Lizzie made it quite plain in that first letter that
29:06she would welcome such graphic and blunt and explicit correspondence and Colin
29:12took that letter at face value and he began to enthusiastically write back.
29:24Lizzie James was a female police officer so they set up a honey trap basically.
29:32One way or another by his responses to this woman he'll either rule himself in
29:38or rule himself out of this inquiry. So there's Colin sitting at home lonely as
29:45famously became known a virgin starts getting these incredibly sexually
29:51explicit letters and every time Colin responded to them they would encourage
29:56him to write even more extreme material.
30:03The correspondence convinced the investigation team that Colin Stagg had
30:08violent sexual fantasies. There was a mention of a knife and that was obviously
30:16the method used to kill Rachel Nickell. The team felt he was further implicating
30:21himself and he may reveal where the murder weapon was located and provide
30:27evidence that only the killer would know.
30:33During the course of the correspondence eventually it was agreed that they would
30:39meet and they met in Hyde Park. As far as Scotland Yard was concerned they're
30:46dealing here with a pathological killer.
30:51Lizzie James purported to being involved in the ritual sacrifice of a mother and
30:57her baby and having sex afterwards and that being the only time she'd ever had
31:01an orgasm and that she could only be excited by somebody who had been
31:05involved in something similar. He just thought she was nuts but he was so
31:11desperate for a relationship he didn't end it after she raised that fantasy
31:16because he didn't believe it was true.
31:20Colin had let Lizzie know that he had been arrested in relation to the
31:24Wimbledon common killing. He described being shown photographs of Rachel's
31:31body and described her lying with her hands as if in prayer. The police said
31:38that was a description that only the killer would have known. At one point she
31:44actually expressed oh I wish she'd done it then we could be together. So there
31:49was Colin desperate to have the relationship and was still not willing
31:53to admit what she wanted him to admit namely that he was the killer because he
31:56wasn't the killer that was a step too far. The undercover officer Lizzie James
32:01never elicits a confession from Colin Stagg but the police decided that there
32:09were sufficient circumstantial evidence to present the case at trial. Colin Stagg
32:15is rearrested. After being held overnight at a police station nearby Colin Stagg
32:23was driven quickly into Wimbledon Magistrates Court charged with the
32:26murder of Rachel Nickell. Colin was remanded in custody for 13 months. As far
32:32as the police concerned Colin Stagg has been eliminated as a danger to women. He's
32:38behind bars the risk to the public is now nil from him apparently and the case
32:44is solved.
32:53On the other side of London the investigation for the Green Chain Rape
33:04series thought that Colin Stagg could well have been responsible. The DNA of
33:10Colin Stagg was checked against those on file. Colin's DNA was not a match for the
33:18Green Chain Rapes so they were looking for another suspect.
33:39Then the Green Chain Rapists team are contacted by the member of the public
33:44who having seen the artist's impression compiled by them felt that he was a
33:50very good likeness of a neighbor Robert Knapper. Robert Knapper presented
33:55himself to the officers as a quietly spoken individual someone who didn't
34:01openly display any sign of mental illness really nothing unusual about him.
34:08Obviously to their mind didn't fit the behavior of someone who would be
34:12responsible for those crimes and seeing him in the flesh so to speak assessed
34:16him in excess of six feet about six foot one six foot two which of course didn't
34:22match the height profile provided by the victims. Police asked him to provide a
34:29DNA sample for comparison he said he would and the officers made an
34:36appointment and Robert Knapper didn't turn up. Sometime later and another
34:43request made for him to attend again to give a DNA sample and again he didn't
34:50attend. When they looked at his height they decided no he's too tall and he was
34:59eliminated from the inquiries. It's easy in hindsight saying well why didn't you
35:05well that is a tough call for me and the fact that you don't get DNA you don't go
35:10chasing the guy for it is wrong. You know Knapper should have been chased.
35:15His address should have been sat on. As soon as he comes out you're nicked.
35:29In October 1992 the police get a call from the manager of a print shop and
35:40they said a man has been in requesting copies of notepaper with the Met Police
35:48logo on it. You know to copy that is is an offense. The man was arrested it was
35:56Robert Knapper. His address was then searched. A handgun was found with 200
36:04rounds of ammunition, a crossbow and an A-Z of the streets of London. The A-Z
36:13contains dots, markings. X's at various locations in woodland areas in the
36:21southeast of London. At the time the police don't pay much heed to this. He
36:29said that these were just areas that he was visiting or he was going for a walk
36:33in. That was his reason for marking the A-Z. Robert Knapper was subsequently
36:42charged for the possession of a firearm and the ammunition. In 1992 it was not
36:52standard practice to take DNA from everyone who was arrested. His offense
36:58was non-sexual. So they don't take any DNA evidence from Robert Knapper which
37:06meant they couldn't link him with the evidence they had from the Green Chain
37:10rapes. Were the officers involved in the arrest and search for the firearms on
37:16the rape inquiry team? Probably not. So you're not getting the link. So much was
37:23paper-based back then that you haven't got the manpower to check everything
37:27that somebody's done and for that person to have the knowledge of what's going on
37:32in the area to be able to link everything.
37:40In July 1993 police received a call from a neighbor of a young woman who lived in
38:08Rutherglen Road who would often leave her curtains open at night. It's a row of
38:17houses which back onto the Green Chain walk and the neighbor says that this
38:23man's been lurking in the area peeping Tom and she's concerned about this.
38:30Police arrived, spoke to the man, searched him. The person turned out to be Robert
38:37Knapper. The detective who apprehended Robert Knapper at the time did make a
38:44note that his behavior was suspicious and that perhaps this should have been
38:50looked into further but it wasn't. There hadn't been an attack on the Green Chain
38:57walk for over a year. Operation Ecclestone had been closed down and so
39:04therefore that information remained locally and wasn't actioned any further.
39:14Opportunities were missed to stop him in his tracks before he did any more harm.
39:21The luck of the devil.
39:34On the morning of November the 4th 1993 the boyfriend of a young mother who
39:49lived in Plumstead came home after a night shift to her flat and he was met
39:58with a horrendous scene. There were clothes all over the place. At first he
40:06thought there might have been a break-in or something and then he found the body
40:11of his girlfriend Samantha Bissett sitting upright on the sofa and her arms
40:18were sticking out of what looked like clothing and his girlfriend had a young
40:26daughter Jasmine and he went to look for her and found her under the duvet.
40:34Clearly thought something awful had happened and didn't look any further and
40:38called the police.
40:45The first day at work I was sent to Thamesmead police station on the Bissett
40:50murder inquiry. You arrive at the police station and all you know is you've got a
40:56female victim. You don't know anything else and it just comes in little bit by
41:02bit by bit and obviously 22 years old you're seeing stuff that is quite
41:10shocking to realize what one human being can do to another.
41:16Samantha had been cut from pretty much her abdomen to her throat. The way he
41:26left Samantha was disgusting, absolutely disgusting. He obviously had no respect
41:32at all.
41:37They discovered the body of her daughter Jasmine and she had been sexually
41:45molested.
41:50Good evening. Detectives say it's the most vicious murder they've ever had to
41:54investigate. Samantha Bissett was brutally murdered along with her four
41:58year old daughter Jasmine. It's a double murder but the circumstances of what's
42:04been done to Samantha is truly horrendous. The police had a very urgent
42:10need to find out who'd done this. Is this the work of a serial killer? Has he
42:14struck already and is he going to strike again? Police want to question a
42:19number of men seen in the area on the night of the murders. Their fear that the
42:23killer might strike again cannot be overstated. In a murder investigation
42:28you're looking for fingerprints, fibers, any blood DNA left by the suspect.
42:35Unfortunately in this case there was no DNA found. There were fingerprints at the
42:43scene which were all accounted for. The best evidence we found was a training
42:50shoe mark and blood at the scene but we have nothing to compare it against.
43:01She was a young woman as we were and you feel a connection to her age group or it
43:08could have been us or and her family as well. You just you because you're in the
43:15middle of it you feel for everybody involved. The whole team was focused on
43:22one thing. They desperately desperately wanted to catch him and wouldn't stop
43:30until they caught him.
43:39Paul Britton was called in to do a profile concerning the Bissett murders.
43:43He felt it wasn't the same. Rachel O'Kell was a blitz attack over a
43:50very short period of time. This killer had taken his time. He had been with
43:54Samantha well over an hour and he felt it wasn't the same. The senior
44:05investigating officer decided to rerun the fingerprint search again. It was a
44:12fingerprint on the headboard of Jasmine's bed and that turned out to be
44:17the perpetrator. The fingerprints were run through the police indices and they
44:26matched Robert Knapper. All of us got a phone call to say they've got him. As
44:38soon as we identified Robert Knapper as the suspect for the Bissett murders his
44:43police file was pulled. When we saw the photograph of him one of the team
44:49immediately said that's the Green Chain Walk rapist. It fits the photo fit.
44:57The Bissett team revisit his previous arrest for the firearms offense. Personal
45:04items have been taken during the course of the search. One of those items was an
45:08A to Z with markings there on. When they examined that A to Z they can see the
45:15markings matched up with the Green Chain rape series locations. He's not gonna go
45:22straight for murder and the rapes were a build-up to that. Realized there was a
45:29lot more markings than the crimes they had before them. So the question is what
45:38else has he done? Is he responsible for other unsolved crimes including the
45:44merger of Rachel Nickell and Wimbledon Common?
