Home Alone For The First and Last Time | Forensics | Real Crime

a 15 year old girl is missing from her family home has she run away or has she been abducted by a stranger what evidence is there who's responsible and can science prove it a crime scene is a puzzle that has to be solved a whodunit a scattering of clues to be deciphered by clever detective work and the power of science the friday night before marie went missing she was at a good friend's place where she stayed the night and she went back to her own home on the saturday afternoon and she was dropped off by her friend and her friend's mother and that is the last physical sighting we had of marie and confirmed 6 p.m on saturday evening and 15 year old marie davis is home alone in the christchurch suburb of papanui her mother's been out of town visiting relatives a first trip away from her two daughters and tonight marie's older sister amy has also gone out marie has a close friend living nearby and she's in contact with her sister so there were no issues with marie being there and everyone was aware that marie was home alone marie didn't go to parties she was nearly 16 but no i don't think she ever went to a party actually that i know of she would have been on the computer with music going or reading a book and she wanted to clean up to make sure it was all nice for me and coming back and she never stayed at home ever on her own so she would just thought this is neat do what i want to do and got all the time to do it yeah janet davis was due to fly in the next morning sunday the arrangement was for older sister amy to meet marie at home at eight o'clock before they went out to welcome back mum but when amy arrived the door was locked the curtains and windows closed and there was no sign of marie the house was locked and secured as though marie had gone away and left the house tidy and clean amy tried phoning her sister marie but there was no answer she tried marie's friends who didn't know where she was marie never came home or answered her phone i flew back and amy was at the airport and the mother of marie's close friend i thought oh amy's crying and for a minute i thought ah she was homesick for me because i'd never been away before without the girls and she told me that she was missing and they had no idea where she was so it was a nightmare missing people are reported to the place every day and quite regularly and the majority are able to be contacted relatively quickly particularly these days with cell phones and the lights but marie's disappearance struck virginia labar as unusual right from the start she had never been missing before for any period of time and and her mother and her sister were very close marie's father died when she was three so they're a very close-knit family and marie had very close friends and for her not to be in contact with him was significant we went in with some of the staff that i mean they had a good look around to find out if there was perhaps a note they'd been left to say you know i've gone somewhere police also looked for any sign of forced entry or disturbance there was none but several items of interest were missing there were some beading items that were missing and most importantly marie's wallet marie's phone and the keys to the house she had a green satchel bag type thing and she always had a phone in it and a little bit of makeup she just never went anywhere without it and that was gone and it did appear well perhaps she's just gone off somewhere so the next morning after we established it you know there wasn't anything highly significant in the house it was really just going and establishing the facts around maurice so talking to some more of her friends talking to the school she enjoyed going to school and had very good friends there she was very much into her art and music she was quiet she was quiet and reserved she loved drawing and she was really good at it she would just spend hours and hours with a sketchbook really talented at artwork it really was just unexplained there was nothing in her background to think that she would have run away or that she was unhappy police went door to door asking if anyone had seen her that saturday night what we call an area canvas so all the neighbours were spoken to and most people in that area knew marie there was nothing that came out or anything that was untoward at all she didn't have access to a car and unlikely to have caught a bus but of course we do ctv footage and look at those types of things and in the early parts of the investigation there were a lot of blanks it just continually was blank blank where was marie why didn't she answer her phone how could a 15 year old just disappear it was a mystery i became involved in the investigation a couple of days in i took on the role of analysing all the phone data we would look at her phone just to see if she'd been texting any friends telling them where she might be going or who she might be going with on the saturday night it showed that marie was home she had very minimal traffic on her cell phone that night just really texting one of her really close friends data showed marie texted her friend at 8 20 pm then didn't use her phone for the rest of the night [Music] the next activity on marie's phone was sunday morning about 8 15 and that's when she received a text message from one of her sister's friends about seven minutes later marie received a phone call on her phone marie didn't respond to the text or answer the call which was strange what was it of interest was that the text message at 8 15 was polling in the belfast area which is just north of christchurch and seven minutes later when she her phone was rung she was polling in the kaipou area which is even further north of christchurch so she was clearly travelling or her phone at least was travelling in a northerly direction out of christchurch that was the first time we had anything of hers that took us away from your home address part of the inquiry then was that where in that area could she be either voluntarily or had been taken there so the sar search team were deployed into that area we based the search from here the kainga hall calculations based on the locations of cell phone towers focus search and rescue teams on stuart's gully an area near kayanga about a 20-minute drive north of marie's home on the edge of the waimakariri river there was some linen property that was missing from our home some bedding material so we had a list of that with the patents on that and also we had a good description of the clothing that she was probably wearing an extensive search began for marie or any items that could be linked to her for the sunday we had six teams in the field of three people so it's 18 of them also we had three dog handlers with another person assisting them so had about 24 people in the field on that first day it's a massive area it's all rural there's plantation or scrabble bush almost seems like a little bit of the needle in the haystack if you don't start looking you're not going to find anything five days have passed and there is still no sign of fifteen-year-old school girl marie davis searchers are combing a massive land area close to the waimakariri river a location determined from her cell phone data officers continue to look for other leads as the time went on it just became quite disturbing we just could not make contact with her the longer marie is not found the greater fears grow investigators call in forensic scientists to examine the family home ideally we like a nice fresh crime scene where there's been no disturbance post event but obviously there's been several days people have been in and out of the house so there's certain types of evidence such as say footwear analysis which aren't really going to be gary gillespie demonstrates what's involved at a crime scene examination full body suits gloves and booties stop contamination from hairs clothing fibers or fingerprints they have to be worn by everyone before crossing the demarcation line into the hot zone so we're ready gary to go into the hot zone now oh yes indeed protect us from head to foot and ready to go simply talking while not wearing a face mask could leave our dna for demonstration purposes we're able to remove our masks so what was the situation at the davis house when you've got a sort of missing person the things you may be looking for is your evidence of an assault blood would be the first thing we tend to look for we'll work our way through room for room with a bright light it's a visual examination and a bright light illuminates the scene and really helps us visualize any bloodstaining [Music] there is a bright light isn't it how bright is that it's a thousand watt light and have a sort of a scan down here and that looks like something there doesn't it yeah very much so it's sort of a nice red brine stain pretty typical of what i'd expect for bloodstaining to me that looks what we call it a transfer stain that's right exactly so so where you've got blood on the surface and you smeared it transferred onto another surface blood staining i'd be interested in sort of doing chemical tests on that so we'll just move across a while onto the carpet you can just see a couple of small stains on the carpet to me they look like what i would call them drip stains so imagine somebody with a bleeding injury or even blood dripping from a bloodstained object so what do you do next we need to do some a chemical test just to sort of confirm that they are indeed blood so if you usually want to hold the lighter minutes here simon okay what we need to do is rub the stain with the test strip and then just drop a couple drops of water onto the test strip and you'll see it come a nice green color what that indicates is we've got blood present so you know it's blood we know it's blood so what we'll do is we'll put an arrow next to it get it photographed for continuity purposes then we'll look to sample it and then we can use that sample for dna purposes at the davis home forensic examination revealed two potential sources of evidence marie's bedroom find two small areas of bloodstaining in one corner of the room which is sort of furthest from the door a chemical test indicated it was blood but they were quite small only several millimeters in size on the floor but they were evident the second area was in the study a small room off the lounge it had a computer in it and there was an upholstered chair and we did notice some blood stain both on the floor close to the chair and also on the back of the chair in one corner and one of the arms of the chair the blood staining on the back of the chair was probably a reasonable size quite light in color um maybe sort of 20 to 30 millimeters in in sort of overall dimension blood stains on the armchair were small then sort of five to six millimeters and the one on the floor was quite light in colour quite close to the colour of the timber i think it would be difficult to observe with without a bright light in a small room with not much lighting you may not be able to visually observe it there was only blood within the study and some small blood stains in maria's room that was all we find the forensic examination of marie's house didn't come up with a lot but it did appear significant and we knew marie spent quite a lot of time in the study there was no other blood in the house that suggested there had been someone that had a bleed so although there wasn't a lot it did seem unusual that there were these couple of spots of blood investigators had to consider the possibility of sexual attack the forensic team were tasked with screening the house for semen but unlike blood semen is not visible the way we look for semen is we're looking for an enzyme the enzyme that is present in semen is acid phosphates that's present in high quantities in semen the process of detection begins by spraying the area with water then damp paper is applied to draw out any enzymes the test area is marked out before the paper is removed and painted with a chemical reagent also starting to discolor here a bit yeah you can see now we're getting this purple coloration we leave it up to two minutes normally but you can see now that's probably within sort of 15-20 seconds quite a quick reaction the discolored area is marked and placed back to identify the suspect zone which would then be sampled for analysis and what did you find we didn't find any semen present on any floor areas within the house the investigation now focuses on the study the computer often used by marie to upload photographs and listen to music is forensically examined marie was most likely using it during her last hours at home marie was working on the computer until around just after three o'clock when there was a song that was loaded on that song played for 238 times without any more interaction by anyone on that computer until approximately 6 30 a.m that morning when there was an attempt to close down the computer and normally the computer has never closed down we could tell from the forensic examination of the computer that that was an unusual thing to happen for that computer that the family wouldn't even normally leave the computer running it raised the obvious question with someone else in the house fifteen-year-old marie davis has been missing from her christchurch home for more than a week as well as the police investigation friends and extended family are doing what they can to find her she was a very loved girl so they started producing posters and actively going out looking for her appeals were made through the media for sightings of her or the missing items the profile of marie was high in the fact that she was a 15 year old girl and at home alone on a saturday night and had effectively vanished it was a mystery that investigators needed to solve further phone data was analyzed including landline calls in and out of the davis home on the saturday night there was a phone call that came into her house about 10 past date that night that phone call lasted about 46 seconds so it was relatively short the phone call had come from the home of marie's close friend where she'd stayed the previous night two investigators it stood out it was a hard line which is um most of the young 15 year olds are using text so it seemed un very unusual as to what that phone call would be about after speaking to the people from the address it became apparent that marie's friend and marie's friend's mother who lived at that address were both at a barbecue that evening and other than that who lived at the dress was the uncle of marie's friend so we then spoke to the uncle and he provided a statement to the police the uncle explained that he was out with friends that evening and he hadn't made that phone call so it was who made that phone call and what was that about [Music] with media and public interest running high police were fielding hundreds of calls all potential leads or further information some sitting late in the evening in the police station and received a phone call from a gentleman who had talked about his sons having been down the waimakariri river earlier that day and had been out on trail bikes and they had noticed something in the river which he described as perhaps some bedding and they had poked and prodded it and they'd seen some or his daughter had seen the news that night of where marie was missing the sighting was at an area some nine kilometres upstream from the original search site there's often things that are dumped in these sort of isolated locations but because we had been searching in the area and we knew there was a likely area that marie might have been in that seemed promising it was a pretty cold night and the river was up a little bit more than normal what it normally is so the the river flow was quite quite swift when we got up there the informant indicated where the linen was i went out and had a look at it and pulled two sheets it was snagged against a log so i removed them and handed them back to the detectives then when i was there i had to look in the water i could see something turquoise coloured in the water so i reached out and picked it up i wasn't sure what it was at that stage but it was appeared to be snagged so i grabbed the other end of it with my other hand and pulled it pulled it free when i pulled it out because it was a bra so i headed that back as well let's see under the water a brown sheep sort of flying in the water it was quite stuck so what i did was just tie that off to a rock on the side of the bank he retrieved all he could in the dark and the dive squad was called in to search the area once it was daylight they recovered the blanket that i'd tied off they had a couple of big boulders dropped on top of it so it was going to be really difficult for us to try and remove that they recovered a wallet in the water her [Music] wallet they retrieved some some lengths of rope as well in all 15 items of interest were found some of the bedding the bra and wallet were identified as marie's that was a turning point to say that that had to be part of what had happened to her you know somewhere around that river so we deployed even more staff out there in that area in the hope that we could locate marie's what we believe would be a body all the material submitted was very damp and really prior to examination you've got to dry it and then sample it and examine it from there on in any item that has been submerged for a long period of time in water is going to lose a lot of evidential value any sort of trace dna material is going to be lost the possibility and semen analysis is not viable any bloodstain may be diluted so the examination of the items in the river we had to bear that in mind within the bedding we found a couple of small blood stains which he sampled and sent off for dna analysis um we also recovered hairs could it be marie's hair or could we do dna analysis on them and establish who may they have come from there was also a couple of items of yellow rope that were recovered and within one of those items of rope there was a small section of what looked like disposable glove attached to it as well we actually sort of undid the knot under dna swabbing of the material underneath the knot just in case the area of rope under the knot had been preserved and to such an extent that we may have been able to recover dna for skin cells etcetera that may have been sort of deposited on it from handling an item no dna could be found on the rope samples or the blood stains but after extensive analysis two hairs were linked to marie davis examining the bra also appeared to confirm the investigators worst fears the hook on the clasp had been swept severely bent back and which is indicative that so some force may be pulled on the bra while it was still being worn or whether when the clasp was still attached police needed to determine who had made the last landline call to marie from her friend's house everyone who lived there claimed to be out but someone had to have made that call there was a consideration you know would someone break into the house and make a phone call but that really was starting to be a bit ridiculous during an enquiry like this we're looking at various people of options and the phone call that came in that night did heighten our awareness around the uncle the uncle dean cameron claimed to be out with friends so we looked at his phone data as to where he may have been and around on that saturday and most in particularly sunday morning once we got mr cameron's phone data it became apparent that he'd been traveling around christchurch city earlier in the evening um sort of from four o'clock in the afternoon through to about six o'clock uh with friends on the saturday night mr cameron started receiving phone calls on his cell phone from his friends that he'd been associating with earlier in the evening that was about just after 10 past eight in the evening which gives an indication that he wasn't with his friends and otherwise they wouldn't be calling him at that time around about 10 past eight when he was receiving those phone calls on a cell phone he was polling in the cell tower closest to his home address about half an hour after that his phone appeared to have moved to a different cell site the cell site closest to marisa mr cameron's cell phone was in the area of marie's house for quite some time well about half an hour anyway but the last time he received any traffic on his cell phone was about 9 30 on the saturday night there was no activity from then until about 10 o'clock the next morning when he appeared to be in the vicinity of kaipoy which was the same area that marie's cell phone had been polling in that morning as well when we establish people maybe a person of interest as to what has happened to someone we start looking at their movements and effectively you're trying to establish that the movements of the person that's missing in this scenario and the person of interest their movements cross over and his movements started to interlink with marie davis and close to her home address police and esr conduct a search of the house where dean cameron lives i understood from information given to me that marie had actually been in the house the day prior to her disappearance this meant finding marie's dna would be expected and therefore easily explained in much of the house so we really concentrated on the bedroom of the suspect in the matter we were probably looking for blood thinning uh present within the rim nothing of any major significance um so yeah we didn't do any dna analysis on anything from the room but police searching the garage find several pieces of rope and latex gloves similar to the rope and glove fragments found at the river it was like a coincidence perhaps but maybe there was a little bit more to that [Music] investigators have identified dean cameron as a person of interest in the disappearance of 15 year old marie davis latex gloves and sections of rope found at his house looked to be similar to those found at the waimakariri river but are they a scientific match dr sally carson of esr's physical evidence laboratory conducted the rope analysis starting with the ropes construction so for this piece here i've unwound the end and you can see that it's got three strands and they're twisted together in what's called a z twist now the z twist refers to the diagonal lines on the rope which are like the letter z and then each of those strands the diagonal lines go the other way as in the letter s so that's an s twist and is that a common way that rope is constructed yes it is it's always the opposite otherwise your rope would unravel so we also can count the number of strands that there are it's very clear isn't it and there are probably i can see between 15 and 20 different strands there and were there a similar amount of strands between the two ropes yes they were we could not tell the ropes apart on any of the testing chemical analysis identified all the rope samples were made from polypropylene and matched in colour even more support that they're exactly the same but it's not conclusive evidence this type of rope is quite common and so there would be other types of rope available on the new zealand market that would also match these samples it provides a link but it's only a reasonably weak link because of how common the rope is latex gloves are also widely available and you'd think near impossible to tell apart but with the help of some high-tech equipment this is exactly what dr carson aimed to do small pieces of the gloves are attached to metal stubs and placed inside an electron scanning machine at auckland university's school of engineering what's actually happening in that chamber then so we've got an electron beam being fired at the latex sample this area in the box here those atoms that are present are being excited emitting x-rays and the detector is measuring those x-rays so here we're measuring the elements that are on that periodic table that's correct so for example the calcium peak those x-rays are emitted at about 3.9 electron volts so at 3.9 electron volts we know it's calcium so sulfur here is about 2.4 and so because it's 2.4 we know that peak is silver i'm amazed at how precise then the measurements you must be able to make are using this piece of cap it's a very high-tech instrument and it is very accurate at detecting the elements that are in there we've also had some smaller peaks come up potassium has come up for that peak and potassium is something that you would expect to find in latex gloves elemental composition differs between manufacturers and even between batches of gloves what did you find out at the suspect's address we had four different types of latex gloves but they were all different to what was found at the scene what was interesting was that out of the five gloves of the suspect's house only two matched so a real variety of gloves at the suspect's house yes there was police were very interested in dean cameron's movements as phone data placed him at kaiapoi near the waimakariri river on sunday morning he maintained he hadn't been at the river nor had marie ever been in his car a potential breakthrough came when investigators found out some sections of the river were monitored by security the inquiry didn't have highs and lows and was like yes this is great because we will hopefully see something at that time the cameras weren't running dean cameron's car was forensically examined for any evidential links to marie we collected hairs which we looked at there was no visual blood staining on the inside and outside of the vehicle we also did semen analysis in case there would have been maybe some sexual event taking place in the car i'm new seaman was recovered from the car we also took swabs from any door handles or whatever that may have been touched by somebody did dna analysis a number of those but overall there was nothing really of significance from the vehicle no evidence of marie was found in the car but could the car be linked to the section of river where marie's items had been found samples of debris were taken to see if they corresponded to the soil from the river seen at gns science these were broken down to release the material palaeonologist dr dallas mildenhall is most interested in pollen and these are things we can't see aren't they oh they're quite small the largest pollen grains you could probably see an individual one by the naked eye but most of them know under the microscope here i've got a slide from the waimakariri river and what you've got on screen there is pinus a very distinctive pollen type it's quite large that'll be about 60 to 80 microns across so that's less than a tenth of a millimeter yes that's really really really small no it's big most of the pollen that we look at is wind dispersed but what we really want to find is something that is insect dispersed those plants disperse their pollen very locally most of the pollen will be deposited within a metre or so of the plant another way is to look at any sort of genetic abnormality but something that is unusual analysis requires identifying up to 3 000 pollen grains per sample databases include his own collection of some twenty thousand pollen slides at gns so what were the results from the waimakariri river the dominant pollen types were pioneers in particular followed by the willow followed by grass samples from the car contained those pollen types as well there was nothing distinctive about the pollen from the river most pollen came from the weeds and from the trees that were growing there and they grow all around christchurch was that disappointing we're always looking for a result and when you don't get one you you are a bit disappointed but that's science and unless you look you won't find the critical clue that may be there it was now 12 days since marie went missing and two days since her bra wallet and bedding from her home was discovered in the waimakariri river for the first week or even probably longer i was in constant denial that i just kept thinking no she's she's somewhere else she's got to be somewhere else but it was only wishful thinking i knew searchers were faced with a vast and ever-changing area to cover the waimak river has a huge catchment it goes all the way up by arthur's pass so it has lots of feeders coming into it and it's quite braided that is it's quite broken there's lots of little branches sort of coming down and it changes as water comes down and it floods it actually meanders quite a bit initially i thought she would be reasonably close i've recovered bodies in there before when someone dies they naturally sink to the bottom and they generally won't go that far and what happens then your body starts to decay or decompose and what that does that builds up a gas and so the bacteria in the body creates that gas and then after a few days depending on the water temperature then you'll float and start drifting down with the current i arrived down there on the morning of the 17th and then i got called by a com saying that motorists driving to work had seen something in the water i had a boat uh jet boat coming there we hopped on that and went to check out the sighting of this object in the water as we were coming back that's where we actually saw marie and what what that happened with her is she started to float down and she came to a braided section that is where a higher section of river is starting to flow down into a lower section so she became beached on that downward part she was still submerged only a little bit if i was out of the water and she was quite hard to see because she was covered with a bit of salt as well so when we located the body and from a policing point of view we knew it was marie and she was naked most importantly is to let the family know before anyone else notifies the family obviously it was overwhelming the grief and the emotion around that is you know always difficult in anyone's police career to deal with and you just know that maria is no longer alive taking marie's body from the river back to do a post-mortem a forensic examination of her obviously our hope then was that our science and our forensics experts were going to be able to assist us in holding someone accountable for what had happened to marie the pathologist was not able to confirm the cause of death he could eliminate certain things but not 100 however he could say it wasn't from natural causes possible causes included neck compression drowning couldn't be excluded there was no sign of predation by eels or seagulls which supported the view the body was wrapped up while in the water as part of the post-mortem swabs were taken from marie's body my own personal view was it may be somewhat limited the body's been submerged we're going to get somewhat lucky to find anything that may be useful i was looking at the slides prepared from the vaginal swabs it's something evident that there was semen present you could see the sperm cells and it's suddenly yeah this could be quite interesting [Music] dna expert kat mcgovern was called into auckland's esr to process the samples under what's termed ultra urgency gary made notes about the number of spermatozoa that he'd seen on his slides so those numbers were very low they were present but they were scored as a rank of one so we knew that they were not the best of samples viewing confirmed the minimal number obvious especially when seen alongside other cells contained on the slide it was a mixture of epithelial cells and spermatozoa so epithelial cells are cells that line body orifices such as the mouth or the genital tract and they were the things that appeared green like big green balloons and then there were smaller oval shaped red cells those were just the heads of spermatozoa the tails break off spermatozoa relatively quickly so in this case they wouldn't have been any tails present the minimal number wasn't the only issue there was also the level of deterioration from being in the river for 12 days researching forensic archives for similar cases only emphasized how difficult the task would be there were a couple of papers that did look at recovering dna from bodies that had been submerged one was looking at recovering dna from underneath fingernails that was a body that had been in a bathtub for a matter of hours not days and one was a case in the u.s where a body had been in a slow-moving creek and they had recovered dna from a bite mark on the neck again just a few hours so nothing like the 12 days that was being looked at in this case dedicated staff worked for over two days to establish whether obtaining a dna profile from the spermatozoa was even possible i think actually seeing the mixed dna profile with quite a lot of information there was quite satisfying given our expectation on the sample was so low to start with from that mixed dna a male profile was established gave us a likelihood ratio of 5 000 which converts in words to very strong scientific support that that male dna component had originated from mr dean cameron rather than male in the general new zealand population receiving that phone call that day was a bit of a yahoo moment not only for me but for all of the staff it's just that satisfaction that you are going to be able to hold someone accountable for such a disgusting and sad scenario of taking someone's life the results from the blood stains at the davis home which had been processed under a less urgent time frame came through at virtually the same time small drops of blood in marie's bedroom were hers but in the study blood stains on the floor and on the armchair were strongly linked to dean cameron after weeks of investigation a case was building many regular users of the river reported seeing a silver sedan speeding along its banks on the sunday morning marie disappeared dean cameron's car is a silver mitsubishi the speed of the vehicle on the riverbank and it's a stony road dust dust going up and people looked and obviously identified that's unusual some of the bedding items were identified as being from dean cameron's home and others from the home of one of his friends witnesses also reported a dramatic change in his behaviour since marie's disappearance he did speak to a friend on about day two of marie's disappearance of him being a suspect for the investigation when it very much at that time she was a missing person and there was no cause for him to have said that to someone and his friends and family did describe his behaviour as being paranoid and quite unusual dean cameron had helped hand out flies for missing marie he also attended her funeral four days later he was arrested and charged dean cameron went to marie's home address and raped and murdered her and took her body and dumped it in the waimak river he'd overheard her talking about being home by herself on saturday night one of marie's friends saw him listening from the kitchen given that the phone call was made by dean cameron too marie whether he had said he was coming around she did know him that would indicate that she had let him into the house much isn't known including whether 15 year old marie fought back there was no signs of struggle but there was the telltale sign of doing cameras blood at that house dean cameron aged 39 was convicted of the rape and murder of marie davis at sentencing it was revealed he'd previously been jailed for four years for sexual violation he'd been released nine months before he attacked marie davis he was sentenced to preventative detention with a minimum parole period of 19 years like her birthday last month she would have been 23 it's hard i learned to cope with it i don't think there will ever be a time where i'll won't ever not think about her when going through marie's things janet found a list of careers marie was considering among them police detective and forensic scientist for me it was quite a big kiss a young missing girl is subsequently fined like homicide it's a high profile case quite tough at times a lot of demands from police quite rightly and it's always nice when something you do you feel has some impact on the final when it gets to court it's still one of the more surprising results that i have seen it's definitely memorable to recover spermatozoa from our body 12 days in a river there were times where it was just like what has happened and who's been involved in this you could draw conclusions but we needed evidence and i think for everyone that was involved it was significant to hold someone accountable but ultimately but rather that it hadn't happened marie davis seemingly vanished into thin air but after relentless police work and evidence provided by forensic science her killer was identified and brought to justice [Music] you
