Tuesday morning ` the 12th of July 2005. A member of the public had rung in, had been walking his dog, had found what appeared to be the body of a... a female. (UNSETTLING MUSIC) Effectively, she's been thrown down this bank like a pile of rubbish. She ended up here in the state she's in. Police identified the body of 22-year-old Katrina Jefferies of Hillsborough, Auckland. She'd never hurt other people, and for someone to hurt her... was really awful. The people she was hanging around with and associating with weren't good people. You know, these are the kind of cases that we join the police for. (BROODING MUSIC) When we're unable to bring someone to justice, that's the hardest thing ` when you don't have closure or aren't able to tell the family of that result. However, police believe it's never too late to solve a cold case, but your help is imperative. We've brought together a specialist team to review some of New Zealand's most haunting unsolved murders. They'll use their skills, expertise and up-to-date technology to look at things with fresh eyes. This is a solvable homicide if the right people just come forward with that little bit extra of information that we need. We all have daughters, sisters, and this is really the chance to do the right thing by Katrina and Nicola Jefferies. Can you help us solve the murder of Katrina Jefferies? ('COLD CASE' THEME) Captions by Maeve Kelly Edited by Starsha Samarasinghe Captions were made with the support of NZ On Air. www.able.co.nz Copyright Able 2019 (PORTENTOUS MUSIC) Early on the morning of the 12th of July 2005 at Auckland's Waikowhai Reserve, a man made a grisly discovery. Between 7, 7.30 Tuesday morning, a gentleman walking his dog on the edge of the reserve looked down and saw what he initially thought was a pile of rubbish but also thought he saw what appeared to be a hand sticking up amongst it. A patrol car was dispatched from Avondale, and on arrival, the officers confirmed that we had a body of a... a female in her... what appeared to be her late teens, early 20s. Police are investigating the death of a woman whose body was found in bush in the Auckland suburb of Hillsborough. Police had to use a cherry picker to retrieve the body from down the bank. We could see a state of undress she was in. He body appeared to be in quite a contorted position. It just started to really reinforce you that we were dealing with something that, you know, appeared quite callous in the way that she'd probably been killed, the way she'd been dumped. She'd been partially covered with black plastic bag, had what appeared to be a yellow PVC raincoat also draped over her. It appeared that she'd either, possibly, been rolled or, perhaps, been dumped from a vehicle. We ended up identifying her through fingerprints, and also, her mum had rung in and indicated that her daughter Katrina Jefferies hadn't come home after leaving on Sunday night at about 8 o'clock. Definitely wanted her to stay home, and she said, 'No, I am going out, 'and I think I'll just, you know, go to the bottle store or something.' And I just... I wasn't able to keep her there, so I just said, 'OK,' you know? I hoped she'd come back soon. So, yeah, that was the last time I saw her. She just waved at me and, you know, and that was it. So her mum's expecting her to come back at Sunday evening. She doesn't, and then Tuesday morning, she's discovered. (UNSETTLING MUSIC) Katrina was the middle child in a family of three, and her childhood was full of time spent with her older brother, Ben. She really loved her older brother, and as they grew up, I think, they spent quite a bit of time together and did things together when it` You know, had friends. Yeah, she was my first, you know, best friend that I made at primary school. Very sweet by nature and kind and just genuine ` like, honest. But growing up, Katrina had a difficult time. NICOLA: She did have people bullying her in intermediate and in high school. It came as a shock when she told me in high school that she was gonna leave. Without an education, Katrina found the real world a struggle. She seemed to go quite introverted and anxious and worried, and she... she spent a lot of time up in her room, listening to music, and didn't really socialise with anyone. (HARD ROCK MUSIC) FERN: We had gone out this one night. I'd really noticed the change this time. She was wearing a hoodie, which she always had pulled up, and I noticed her skin, you know, had really gone downhill, and she just... kind of was just hiding herself and didn't really wanna be seen. She'd always wear a cap, and she pulled that down over her eyes. Towards the end of her life, she liked the night-time better, because no one can see you in the night-time. Adding to Katrina's strain was the loss of her older brother, Ben. Ben drowned in '99 in the sea, when he was on holiday with his friend, so Trina was really devastated when he died. I knew how much she looked up to her big brother, Ben, and how close they were, and she was really hurt talking about it. She didn't care about herself after that. She just... I guess the best way of putting it is she didn't seem all there. Unbeknownst to her mother, Katrina turned to alcohol. I didn't see it coming ` her sneaking and drinking so much. I was actually quite shocked at why she did that, and then I realised what was going on ` she'd developed a taste for alcohol. It was really sad. Um... Yeah, just... it just wasn't her any more, and I just... I found it hard, (VOICE BREAKS) um, seeing her like that. I really wanted to help her, and I tried many times, and... I feel that she just pushed me away, and sometimes I felt she didn't wanna be helped. I mean, I did care about her, and I tried everything in my power to get her on the straight and narrow, but... you know, the person has to care about themselves. Katrina also started seeking companionship through the phone chatline Hot Gossip. Through this, she found parties, met men and would often stay out all night. And I was very stressed about it all the time. Number of times I'd waited for her to come home or needed to talk to her ` where was she? You know, found out if she's OK. So it was horrible, actually. At 19, Katrina became pregnant, and her mother hoped it would mean a new beginning. You know, she always loved her son. She was very gentle with her son and cared about him, but, um,... she really didn't stay around very long after he was born. She, kind of, only... Maybe a month or two, and then she decided she wanted to go out again, you know? She wasn't gonna just stay there in the house, for some reason. Yeah. I just knew that there was a lot she wasn't telling me. I knew that the people she was hanging around with and associating with weren't good people. They didn't have that love for her that I had for her ` (VOICE BREAKS) that... that genuine love that you have for your friend, that you want the best for them. And that's what I found hard ` is that she couldn't see that. When Katrina died, her son was only 2 years old. The homicide was described as 'a real whodunnit', and to this day, the cause of death has never been publically revealed, although it has been described as 'highly unusual'. Three suspect teams explored every possibility. Was a stranger responsible for Katrina's death or did the young mother die at the hands of someone from her long list of associates? Just in terms of persons of interest ` over a hundred people just with a lifestyle that, you know, Katrina's had, and her Hot Gossip people in the neighbourhood. So, in that Mt Roskill area, you've got drug, alcohol issues; you have some gang issues. And the fact that she wasn't getting a regular income, she was having to, perhaps, sometimes, source alcohol and drugs, for, perhaps, sexual favours and that sort of lifestyle. Initial speculation focused on one male whom she met through mental health services. She had a... a partner, for want of a better description, who was a lot older than her. Similar lifestyle to Katrina ` was also, uh... suffered from mental illness; dependent on drugs and alcohol. He became mentally unwell following her death. So, it wasn't until, I think, a year later, once we got a really good picture on that particular male associate of hers that we were happy ` to some degree ` that he wasn't responsible for her death. Despite an extensive investigation, police weren't able to charge anyone with the murder, so in 2007, they took extraordinary measures. Almost two years after the murder of Auckland woman Katrina Jefferies, police are offering a $50,000 reward for help to find her killer. URAIA: New Zealand police doesn't often do this. We do so, though, in cases where we struggle with getting the information from communities. The reward also offered immunity for anyone who may be involved but could provide us with some crucial information in terms of who killed Katrina or the activity that occurred after, with her dumping. Yeah, unfortunately, no one, again, came forward. Although this reward is no longer offered, 14 years on, police are hoping that a new cold case investigation will finally lead to justice for Katrina, but they need your help. People need to be, you know, brave. People need to do the right thing. We all have daughters, sisters, and this is really the chance to do the right thing by Katrina and Nicola Jefferies. I reckon we could run off with it before (GRUNTS) anyone notices. I reckon you're a tool. Eh? (GRUNTS) Want a hand with healthy? Tear into one of our tasty Sealord pockets. It's a fusion of real ingredients and delicious tuna that's gently slow-cooked to lock in the flavour, and that's what makes our pockets * In 2005, Katrina Jefferies was found dead in Auckland's Waikowhai Reserve. Nine years later, in 2014, her case was reviewed, and a new murder investigation, Operation Lyra, was launched. There was four of us, initially, that spent probably about three months reviewing the information, trying to piece together a jigsaw, really, and see what areas we could develop or work on more. We embarked on a secondary area canvass of the Whitmore, Skipper, Mt Roskill area, and that led us to some interesting information ` led us to piece together Katrina's weekend, events that happened the previous week that might give us a key to who she was with, where she went. The second investigation identified new persons of interest from the community, and with the renewed focus on Katrina's neighbourhood, police uncovered a violent serial predator. ...56-year-old Auckland man has been sentenced to 19 years in prison following a string of violent physical and sexual offences against his former partners, spanning 30 years. The judge described how 56-year-old Michael Te Huia regularly raped two of the women with callous entitlement. She went on to say that the lives of his three victims would have been one of utter misery. We did apprehend, or arrest, someone from that community, and he did face some serious sexual charges, for which he was convicted. However, his charges and his conviction was unrelated to Katrina Jefferies. Over the past 14 years, police have gone to extraordinary lengths to solve this cold case. They now hope the 2019 review will finally bring Katrina's killer to justice. Leading the investigation is uniquely-positioned Uraia Vakaruru, a member of the original team and now the current officer in charge. Yeah, it was a sense of, you know, 'How could somebody do this to someone as young as this?' Effectively, she's been thrown down this bank like a pile of rubbish. Detective Senior Sergeant Bridget Doell is the 2IC on Katrina's case and is determined to see a resolution. Getting to know her and who she was a bit better by looking through some of her personal items, diaries, you just really get a sense that she was just a 22-year-old woman just trying to focus on her life and her child as best she could. And Detective Jennie Nicholas, who also worked on Operation Lyra. Somebody in the community knows who killed Katrina Jefferies. Three detectives; one cold case. And we will also be asking for your help to solve this homicide. Katrina would've been 37 years old this year. Her son and Nicola Jefferies, we owe it to them to solve the investigation. In terms of Katrina herself, though ` thoughts around what we might need to revisit there? We know that she was quite an anxious young lady. She suffered from depression. She'd run out of her prescription the weeks leading up to her death. She was very shy and, perhaps, trying to, maybe, alleviate her depression or anxiety by drinking or taking drugs. Her friends and family describe her as a kind, quiet, caring person. Others describe her as someone that was actually quite a free spirit once she'd had alcohol and drugs on board. She may have become quite a different person. Yeah, she didn't have her driver's licence, so she often relied on different people to give her rides places or she would just go out walking. Her mum said she worried about her at times, cos she would go out walking at night often to search for alcohol or drugs. So I think centring on that close area where she lived is really significant. In between the time that she left home on that Sunday night and the Tuesday morning when her body was found, I don't think we've got any sightings of her at all, which is significant. Someone other than the killer would have seen Katrina in those 36 hours. She was known in that community. Katrina's mum asked her where she was going. She walked down the path and ` in a cheeky way, I think, her mum described ` 'I'm just going to get some alcohol,' or 'I'll be back soon.' Perhaps she was heading to a local drug dealer. We know there were several in the area. And when you're thinking about her demeanour and how she was feeling ` we do know that she had an abortion the Wednesday prior. She was very upset about that. She was very distant and, um, unhappy. Felt like she was trying to numb herself. She found that decision really difficult, and we know she did go to a party nearby, just around the corner, on the Saturday night. We've got witnesses that say at that party, she was quite emotional, and they wondered why, and that could be related to the termination, perhaps. The team agree understanding Katrina and the community she lived in is vital, but there is a sense that fresh expert eyes could break this case wide open. In a bold move, the team brings in behavioural psychologist Shreena Hira, who currently works in the New Zealand Police's behavioural science unit,... We're supporting police by providing a psychological frame to the things that they're seeing. So if we are able to look at behavioural characteristics of victims and of perpetrators, persons of interest, we can then use that knowledge to assist police. ...and Kris Illingsworth, who not only has 25 years' experience with the New South Wales Police but is also an FBI-trained criminal profiler. I analyse and interpret the behaviour of crime scenes, victim and offender behaviour, and develop criminal profiles of the unknown offender for the investigators. It's an opportunity now to have you both on board in terms of finding out a little bit more about the victim and the person or persons responsible for the death and the dumping of the deceased. Maybe starting with you, Kris. Yeah. As I understand it, Katrina was a heavy consumer of alcohol. I like to start off with victimology. I like to understand who this person is. If we have a better understanding of a victim, we can then try and understand what may have occurred and also, by inference, try and understand who the offender may be. So someone around her might view her as being quite vulnerable and available to an attack, and in their mind, they might consider her to be somewhat like a prostitute, someone who could be used and tossed away. Of note, I think it's important that she did have a termination of her pregnancy earlier that week, so I think escalation in alcohol or drug use over that time would be reasonable to suspect for her, although I agree she likely was regularly using drugs and alcohol over that time anyway. And she suffered from depression, and how would that affect her? Generally, that would be presented in a way of feeling nervous or worried in larger social situations or feeling judged by others in smaller groups. Consume the alcohol to feel OK. URAIA: To mask her? Yep. Yeah. Mm. Yeah. Mm. Once we have victimology sorted out, we then consider what kind of risk this person was at becoming the victim of a violent crime ` a low-risk victim, a moderate-risk victim or a high-risk victim. She was highly vulnerable because of her intoxication and available cos she was a woman on her own ` young woman on her own. And so you put those two things together ` vulnerability and availability ` and she comes out as being a high-risk victim, which means, when someone is such a high risk, they're really open to anyone attacking them, cos they are so vulnerable and so available. Having established Katrina's extreme vulnerability, what secrets might the crime scene reveal to the Cold Case team? * In 2005, the body of homicide victim 22-year-old Katrina Jefferies was found dumped in inner-city bush along Waikowhai Rd in Auckland. In order to better understand the murder, criminal profiler Kris Illingsworth is joining detective Jennie Nicholas at the dump site, only a kilometre from Katrina's home. JENNIE: So, Kris, Waikowhai Rd is just over half a kilometre in length. Just before the 500m mark, there's a gate that gets closed off and locked in the evenings. OK. KRIS: So, the training is all about analysing behaviour at crime scenes ` looking at the victim behaviour and the offender behaviour ` and it's a different way of looking at a crime scene to what a detective would normally look at. In 2005, this was an open clearing. So none of this foliage at the front here was present? No. No. You use all of that information the detective gathers, and you apply the concepts and the training that we have and look at what happens in the crime, why the certain things happen that way. I'm not sure what the slope is, but it's just incredibly steep. It is steep. There were tyre tracks just along here,... OK. ...which indicated that... Well, that's good. Yeah. ...a car pulled in here. Well, that makes sense. They come up the roadway, having turned around at the roundabout... Yep. ...and then pull in as they go` They wanna have a quick escape straight afterwards. Right. Remove Katrina from the vehicle, put her down on this ground, and then they'd expect her to just roll down the slope ` it's so steep ` Mm. Yeah. ...but she hasn't. No. And once you've worked out all the whats and all the whys, you go in the direction of who. 'Who' as in the type of person will need to commit that crime in that way. It seems to be a local rubbish dump site. That tells me that this person has strong local knowledge. People who live further away, in other suburbs, they wouldn't necessarily know that that exists. You have to find a spot where to get rid of Katrina's body, and so if you know that spot's there because you've been there before dumping rubbish, that spot is in this person's mental map. So, what we know through the concept of routine activities theory is that criminals will usually commit crimes within an area that is familiar to them or an area that is within their cognitive map ` places that they frequent a lot or they have in their awareness on their day-to-day functioning. So this is someone in this very close area, again. It's only 1.1km to Katrina's place. Yeah. I mean, I agree, and the way in which the body was found and the objects around it also suggest that there was an element of making this also look like rubbish, which, therefore, would suggest that someone had knowledge of that spot, and therefore a local. I think the other key too was in the fact that if the offender or those responsible for disposing of the body want to minimise the risk of detection, they wouldn't drive long distances with the body in a vehicle. I was struck by how steep that embankment is, so I imagine that the thought process would be, 'We'll take her to that rubbish site that we know and then throw her over, 'and she'll roll down the hill, out of sight.' But that didn't happen. The body's found only 2m from the top of the slope. Bit of a shambles when you look at it. Once the body's down, then he's back to the vehicle. That's what he's thinking about ` escape. JENNIE: Adrenaline's pumping. You wanna get out of here as fast as you can. This is the most high-risk part of the whole thing. How long do you think it would've taken ` the whole process? I think by the time he got her out of the car, down on to the ground, tried to get her down the hill, could be looking at around about three minutes. Two, three minutes. Right. Fairly quick, but it's a little bit of time here. Mm-hm. Yes. And the reason why someone does not want a body found, usually, when you have such a disorganised disposal site, is that they feel there's a connection between them and the victim. So if you're a complete stranger like that, you don't need to go to that effort, but if you're known to the victim and other people know that you're known, then that drives you to make that extra effort to hide the body. (LAUGHTER ECHOES) So that also suggests that the offender is known to her, as well as what we've already talked about with victimology. If the scene of the crime is within the perpetrator's own home, it would make sense to try and remove the body from that placement. Another reason why a body might be disposed of is because there's a prior relationship between that person and the victim. If there is a way that that victim can be linked to that perpetrator, the act of disposing of a body would reduce that link in some way. The Cold Case team next considers the conditions that night. There was a new moon just moving into a first quarter, and on top that, you've also got the bad weather, so it's cloudy, black sky. URAIA: Would've been pitch-black, you know? It's gotta be really hard to see what you're doing. It lends some support to the theory that there was a second person up the top, perhaps with a torch. SHREENA: And I guess we have to think that these people were in a hurry. And there's haste. Yeah. You look at this scene, it's all haste. When she was found outdoors, her socks were clean. She'd not been walking around outside. We can assume, that given the body was disposed of in Waikowhai Park, that that wasn't the location that Katrina was murdered and that it may be likely that the location where she was murdered is nearby to the park or nearby to the home of the offender. KRIS: She was going out in search of more alcohol that night, and probably drugs as well. She would've gone to someone's place who she knew, and it's gonna be close ` really close to home ` and we know she was in an indoor location. It all indicates that the initial contact site with the offender, the physical assault site and the murder site were all the one place; and there we have the second site being the disposal site. Mm. So there's two sites. It comes back to a very unsophisticated type of crime ` disorganisation. The most thought that's gone into this crime is in, 'Where are we gonna put her when she's dead?' Mm. 'How do we get rid of her?' Turn your minds to the items that were found with Katrina, and we know they're quite unusual, each one of them. There's the red tarp, the yellow raincoat, which is an adult extra-large size ` it's a New Zealand brand that ceased manufacturing in 1980 ` and the large painting print of a landscape. Those in themselves are quite unique to be used to conceal a body ` the colouring, the type of choice of those items, the large size of the painting. The Cold Case investigators are now prepared to release details of one further item in the hope it may provide a link to Katrina's killer. The marine-type plyboard ` an unusual shape ` with a cut-out piece, as if it's been made or moulded to fit the base of a... boat, perhaps. It's got unusual paint rolly brush strokes. Be interesting to know its history. A) How did its shape get cut? Who did that? What colour the paint was, how that paint came to be on the board. Physical testing through our scientists can identify the type of paint, so that is underway, and... Yeah, that'll be interesting. ...you know, look to see whether we can match that with, perhaps, a boat that had been painted. Superficially, it might seem like they're unusual or different or random items, but you've got two items which are largish flat items ` relatively sturdy in some way ` and the other items, while differing in colour and shape, are flexible items which may be then used for covering. So they may have been items that have been collected in a hurry but have been collected and chosen for functionality rather than an excess of forensic knowledge, in terms of concealment. That's exactly right. The functionality of them ` that was their value. They served their purpose at that moment, and they were to hand. And those items had been in contact with the body. So they would've been sourced from the premises. If they were retained, that would be a forensic link to that perpetrator, so I think there's some logic in discarding those items alongside the body in an attempt to, sort of, reduce that forensic link. Further police investigation into the items yielded a surprising a vital revelation. All of those items we have traced back to a house within the Whitmore Rd, Skipper Ave, Mt Roskill area. Although police have evidence the items came from a house and not the dump site, how closely does this connect the offender to that house? The team considers all the options. I think it's unlikely that someone's put efforts into sourcing these items from other places. I think that presents as a high-risk behaviour, in terms of being discovered. Yeah, and if you did get it from some house up the street, you'd have to walk down the street with a red tarp over your shoulder and a yellow raincoat. The likelihood of being seen by someone that you know picking up something out of someone's property... Yes. Yeah. ...or out of their rubbish would've been relatively high at any time of the night, really,... That's right. ...because there's a lot of parties that have occurred at this address. And if there's a reward in place, then someone not connected to the crime, seeing that, is more likely to come forward... Absolutely, yeah. ...and give that information. Brings it back to the items coming from the property. Mm. And what` Yeah, what is interesting is that no one else has come forward to say those items belong to them. So the offender must've had some link to this address. KRIS: Yes. Although there are reports of the distinctive items at the address before Katrina's disappearance, police believe there are people who know more about these pieces and how they were used the weekend Katrina was killed. So with the public's assistance, this is a solvable homicide. * The Cold Case team has confirmed 22-year-old mother Katrina Jefferies was killed at an as yet unconfirmed location and then transported to where her body was found, dumped in an Auckland reserve in 2005. But when was she killed? (UNSETTLING MUSIC) Yes, I believe that the crime happened that Sunday night, early hours of Monday morning, and that she's been stored until the disposal time. There's a number of things that support that. Firstly, she wasn't seen. If she was alive on that Monday, someone would've seen her. She often went home ` even if it was in the morning, if she'd been out all night. It all indicates that the initial contact site with the offender, the physical assault site and the murder site were all the one place, were all the one... in the one house. And she's stored out of sight, so a spare room, perhaps, or a spare bathroom, perhaps, or it could be a garage or a shed ` somewhere where people are unlikely to go in and see her there ` and she may have been covered over at that point, perhaps with the tarp that was later found with her. Secondly and equally important is lividity ` the pooling of blood after death. Lividity is detected by marks on the skin and is fully set after six hours. The blood that settles after circulation stops when a person dies... Blood settles in all the lower parts of the body, and so to look at later, it looks purplish, reddish, pinkish. And lividity does not disappear; it's set forever. And so you can tell from that what position the person was left lying in after death, and that lividity is not consistent with the position in which she's found. The Cold Case team believe all the evidence points to Katrina's murder taking place on Sunday night or early Monday morning in a location that's familiar to her. It's winter; she's indoors; she's taken her jacket off, and she feels comfortable where she is. She's not perceiving any threat at that point. We know that she did visit certain houses in that neighbourhood, from our inquiries. I'd be interested to know your views on whether you think it's definitely a sexual attack. Yes. The lower clothing missing, the shoes off ` that strongly suggests this is sexually motivated, that things start to happen in a sexual way with Katrina. So, because of her injuries, do you think there was a way to work out a sequence of events that night? Yes, we definitely plot a sequence of what happened in the attack. There are a number of injuries around her head and neck area, and what we can see is that... there's not the... what we'd see with, say, a frenzied overkill situation. There's not any of that. There are several injuries which suggest that things started to go wrong for Katrina. Given the alcohol reading, well intoxicated, so she would not have been in a good position to be able to defend herself. She actually has no defence wounds, no bruising on the rest of her body; it's concentrated... Right. ...in the head area. So Katrina's had small opportunities to resist, and she's just done her best. She definitely was not going along with what was happening. So the offender has forced the attack on her, and then the crime has escalated very quickly into a more serious situation. So, an injury happens to Katrina that... incapacitated her in a serious way. The exact nature of Katrina's injury and cause of death has never been released publically. It's believed it would have, at the very least, left Katrina immobilised. She's in a bad way, so the offender has a choice. He can either obtain medical help for her ` which she needed ` or he can ignore that need and look after himself instead. The team now explore the possibility that an associate has been called in. It may be that the second person was brought in reluctantly. It may be that they were intimidated or threatened to become involved or they had some kind of pre-existing relationship which they felt compelled to be involved. If something untoward has happened and you don't know what to do, who would you call upon for assistance, in such a serious circumstance? It's most likely somebody who's also a resident from that house ` somebody that they know, that they trust, that they believe will protect them. And when you add all of that up together, that sounds like a... a member of the family. Also of significance to the Cold Case detectives ` sometime between arriving between the first site and the discovery of Katrina's body at the second site, several items of Katrina's have gone missing. There was some clothing that have never been recovered. BRIDGET: There's a black duffel coat that we know that she left home in; blue tracksuit pants; her mother's maroon/burgundy slip-on shoes, size 10, that were too big for her but she still used; a peak cap; and a Walkman, a black one, which was a cassette player. 2005, I think they might have been just phasing out the cassette player, but she obviously still coveted it as a useful item. The offender or offenders would've wanted to get rid of those items too. I don't believe they'd be retained as a souvenir or trophy. Those items may have links to the offender. They may have DNA on them; they may have traces of hairs. It's likely that a perpetrator would want to distance themselves from those items, so they may have been disposed of ` they may have been burnt; they may have been dumped in a different location. BRIDGET: So none of those five items have ever been located,... It's crucial to find them. ...and it's crucial, if anyone recalls finding those items, together or separately, and may not have made a link to Katrina's death ` whether it be a rubbish man or anyone else stumbling across those single items. Mm. Even though it is a long time ago now, someone might recall being given a Walkman or stumbling across a bag somewhere with these items. Do you have any information on the whereabouts of these five items that can help solve the murder of Katrina Jefferies? * Over 10 years after the brutal murder of Katrina Jefferies, police received information about a vehicle that had been allegedly used to dispose of Katrina's body. Unfortunately, that car was crushed well before the report had been received. However, on review of the file, the Cold Case team has found a potentially corroborating sighting of a vehicle near Waikowhai Reserve in the early hours of the morning, about six hours before the young mother's body was discovered. A witness coming home from picking up a family member at around 1.25, 1.30am, was coming towards the Waikowhai Rd entrance, and he slowed to a stop to turn right down Quona St. While he was stationary, with his indicator on, he saw what he describes as a maroon vehicle, stationary, with its headlights pointing out. So, it's approximately 50m from where they were, seeing the car here. And seeing the car stationary, yeah. Stationary. And they described it as having the boot up. And was anything happening around the car? They described seeing a male walking towards the Caltex... OK. ...and that this male didn't have a shirt on, and then there was another person at the car, walking around to the driver's side. It looks like the person without the shirt has left this car and gone over there for some reason. Yeah, that's a possibility. The witness didn't see this person get out of the car, but he was walking from the car over to that direction. What do you think in terms of the witness seeing that car and their recollection of the colour and things at that time of night? Yeah, I've had a look there at night. You've got distance, darkness, street lighting, trying to figure out ` briefly, whilst you're making a right turn ` what shape of car it is, what colour. It's obviously a dark-coloured car, but to say that it's maroon might be a little too specific. Maybe a burgundy or a darkish-red colour, something like that. This fellow with the shirt off,... Mm. ...that's really interesting, because it's a cold night; it's only around nine degrees; it's just been raining, so the air's cold and moist. Mm-hm. In middle of July, middle of winter, why would you have your shirt off in those conditions? That would be consistent with someone who'd been down that embankment. Why do you walk away from a car? So, you're probably walking home at that point, because the car's going in another direction, or something's happened at the car and they've decided to split up for some reason; and it's just too coincidental that they'd be in that location, at that time, just 135m from the site, at a time that we could expect the offender would be in that area. In addition to the witness account, police are now prepared to release, for the first time, CCTV footage which may corroborate the statement. This footage, from a motion-activated camera only 25m from the dump site, shows a car going down Waikowhai Rd and then returning almost three minutes later. Tests were done at the time to ascertain how long it would take for a car to drive down Waikowhai Rd, dump a body and then return back up to the road, and that timing fits in with the CCTV perfectly. It is crucial that we hear from members of the public whether they were in the Waikowhai Rd the early hours of Tuesday morning. It could be that that vehicle is unrelated, but the significance of the time... Mm. ..and how we know, or think, Katrina's been taken there by a car ` it's relevant. We're a little bit closer, but the real closure we'd all have is once those that have committed this cowardly act are taken to court. Police get caught up in these investigations as well, and they can spend a large chunk of their lives and their careers working on just one case, and it can take its toll on investigators. I still drive along Hillsborough Rd and think, 'Waikowhai Reserve. Yeah, that's where Katrina Jefferies...' And someone's still out there, but their day will come. BRIDGET: So it's not something that ever leaves you or leaves the team. Jen, Bridget and Uraia are very invested in this case, doing their best to solve this crime and to help Katrina and her mum, and I can see it's... it's affecting them and that they want to get this closure on the case as well. As the review comes to an end, the FBI-trained profiler offers her findings to the team. So, a male person, because there's a sexual element to it and the assault aspect; and given the racial demographics of the area, person is most likely to be Maori or Pacific Islander, alcohol and drug user, doing what Katrina was doing. That's why he's in her circle. Due to the lack of organisation with the crime, average ` at best ` intelligence levels. He'd live with others, cos you've got this secrecy aspect of concealing her in a crumpled-up, out-of-the-way spot. There's been a reward offered and no one's come forward to claim that reward; just adds more to the belief that this is a family situation, so I think there would have been, in the very least, police contact with this location that he lives. Someone who was known to Katrina, but it was not someone who was a caring person towards her; someone who had a... a distant or using type of relationship with her. He could have some assaultive behaviour as well. A person who lacks empathy, who is, um,... probably somewhat of a cold, callous type of person. And because of that, they're probably in relationships that involve violence, and anyone who's been in a relationship with this person has probably experienced physical violence and sexual violence with this person, been the victim of him. There are people out there who know what's happened, and it's now time to come forward. This will be solved. I have no doubt that this will be solved. We just need that little bit more to get home on successfully prosecuting someone for this. Even if you were involved and were compelled to be involved, we wanna hear from you. Or anyone that's got any information that they believe is minor or wouldn't help ` you just never know. Mm. It may be very helpful, and it might be the missing piece. Some people that have knowledge of what happened may themselves be parents, and they might want to break free of the knowledge of what they know of the past to move on in their life. Imagining themselves being in Nicola's shoes ` losing a child. They themselves might have children. It must be a real burden on them and their mind to know what they witnessed or what they were involved in. The thing I'm glad about was the night she did die, she said, 'I'm going out.' I said, 'Well, you shouldn't go out, because, you know... Stay with us.' And she said, 'Oh, well, I don't care, Mum. The two people I want are safe, and that's all I care.' You know? 'The two people I love', she said, which was me and her son. So I'm happy she said that before she died. We won't rest easy until we've found this person and have justice for Katrina. Whoever they are, I don't know how they can live with themselves. I just think... they're very sick... and not well, (SNIFFLES) and I just hope that that they get caught. We believe we can solve this if the right people just come forward with that little bit extra information that we need. This weekend, police have announced a new reward of $100,000 for information in the hunt for Katrina's killer or killers.
