wealthiest people live why do they keep such a low profile may have snoop around to catch a glimpse. of a war it is hard for the world to discover the super rich starts to take on the job. of. this investigator is using virtual reality technology to digitally revisit the scene of a murder. law enforcement across europe are working with the latest tech to track down criminals and even prevent crimes before they happen. but. he was caught he was trapped. by the new issue this. investigation.

new tech and techniques are transforming law enforcement. this been a murder and rough brick and floor inch bear from the varian state police have been called to secure evidence usually this work will be done by a police forensics chain breaker and bear work for another special unit. i've. the crime scene has been recreated an actor is lying in the kitchen in the same position and location as the victim was found in the resigns of a struggle and of alcohol can. sumption breaker and she will begin gathering

evidence but they won't be using cameras and measuring instruments. the circular let's use the structured like 3 d. scanner this looks a bit like a shoe print as we put. this scanner captures the injuries to the victim's head in an accurate and true to scale straight day image the equipment costs 80000 euros and it can record every single digital detail of a crime scene. not what senora 10 years ago crime scenes were only photographed now we also use a laser scanner for serious felonies of the advantage is that the recorded image is 3 d. giving us an exact digital replica of the real life crime scene. this is such a replica of another crime scene the detail treating scan is stored in an archive so the police can review it at any time. break and his team record about

60 crime scenes a year mostly felony crimes of. the offices need for scans to capture this room in the process takes only 12 minutes. discovered a kind of it's this scanner can't see through that table was pushing me so i have to move it to get a complete an image of the room as possible just looking also to a. brick his team also take $360.00 degree panoramas of the room the scanners record in black and white and the photos will be used to add color to the scan later. the last step involves a full structured like 3 d. scan which is accurate to $100.00 my crim ages history delays the scan by

comparison is accurate to within one millimeter meaning that using the structured light scanner to record the victim's wounds gives the investigators an image which is more than 10 times more precise. that's often say he shot the victim suffered a massive blow to the head and from the look of the stripes here this imprint was caused by a shoe sole and most of what we're hoping is that we'll be able to compare the marks on his head with the suspects shoes up like. determining whether an imprint was caused by a specific shoe is hard to do with 2 d. photographs because these can distort images 3 d. images are different. and this scan shows that the imprint was left by a shoelace eyelets an important fact that could prove useful when identifying a suspect the fact that it is now possible to digitally record and archive entire crime scenes is changing the fight against crime. that's perfect if it's becoming

increasingly difficult to commit the perfect crime. we have new and better equipped more precise devices like these 3 d. scanners which allow us to capture store and evaluate more evidence than we ever could in the past. high tech devices aren't only being used to investigate murders. kilda bryant is a police officer in the city of new girl. he and his team are on the burglary beat burglars a particularly active cheering long winter nights but the offices in broke haven't you told. you i had to recount welcome to the night shift we've had some break ins over the past few days particularly in the neighborhood of calcutta and around so you can bring. all. the team uses a software program which analyzes burglary statistics and predicts which

neighborhoods are most at risk for tonight it has flagged one area in particular. and this does not hold a car that has a tallish pass stuff yet it was one of a stretch between house numbers 140 to 150 so that's where we'll focus our patrols tight i have a lookout for any vehicles from the who are region volatile criminal groups from there have been working in and around the city and also all. hildebrand and office over a bare ground half head out on patrol in the past they had to rely exclusively on their instinct and experience to catch burglars now they're putting their trust in the predictive software to tell them which areas are most at risk and to help the offices prevent break ins. as i fear to have this neighborhood has a large number of single family houses but they're at higher risk especially in winter when it gets dark earlier because perpetrators can tell whether someone is

home from the lights out on a plus burglars expect to find more valuables in single family homes was over the outer. serial burglars will often return to a given area again within 72 hours to hit the 2nd property also because they nearly the night. whored the software capitalizes on this tendency. alexander gluepot of the lower saxony state police helped develop the computer program it's called free map and it helps identify whether a particular break in was committed by serial burglars and thus whether they are likely to strike again nearby. kid or titans he thought the burglars in this case focused on stealing jewelry which is easy to carry and easy to sell it it's much harder to go unnoticed when you're carrying bulky electronic gear on the british class nor. the yellow areas on this map indicate neighborhoods that have particularly at risk the break ins the software identifying the areas means police

can geographically focus their prevention efforts. but will the calculated projections prove correct the officers will soon find out. meanwhile the investigators in munich have assembled there 3 days scared. break and his team found bloody footprints in the kitchen with the help of the chemical luminal luminal reacts with iron found in blood causing a short lived blue glow. if they can see here that will work well for a 3 d. comparison the 1st 2 weeks of. breakers college degree is in

geographic information science but he's been working for the bavarian state police for 10 years at 1st he did his job alone now he leads the department's team for photo technology and trade in crime scene imaging. he often deals with cases like this double no. luminal treatment has turned trace elements of blood that wouldn't be visible to the naked eye blue 3 d. imaging is expanding the possibilities of what can be learned from these traces. often reveal shoe prints for example before these prints couldn't be examined but now we can incorporate them into the 3 d. scan and then if we get given a shoe that might have been involved we can compare it with aluminum friend. you couldn't do that before. and since the 3 d. image of the crime scene is preserved in an archive officers can go back to it long

after the real one has been contaminated using virtual reality technology. several investigators can be within the same virtual crime scene at once the officers can communicate with each other and even move around including the victim's body. through one can you measure the distance from the table leg. to his head. say 77 meters. ok he couldn't have been kicked like that. could you move the body a little closer to the table my mom. exactly so that i can see it better. all that work i asked the boy who can fish that we'd like different types of experts to be able to use our virtual crime scenes in the future besides the medical examiner's could carry out tests on blood stained patterns and ballistics could use our virtual last 2 in on some version led to a from. the 3 d.

model can also be used to determine whether a crime witness is telling the truth in this case a witness testified that they had seen their neighbor. in game 5 of the off the prosecutor's office was trying to determine the precise field of vision and that's easy for our team to do. or we simply combine the view from the 2 windows and could thus tell exactly which area was within sight of. the 3 d. imaging can therefore help prove or disprove a statement provided by a witness. authorities in switzerland a using a different kind of 3 d. technology to help them with their investigations. to the institute of forensic medicine at the university of zurich preparing to

conduct an autopsy on the body of the shooting victim. but there will be no surgery in the traditional sense this is going to be a virtual autopsy. forensic specialist dr michelle tali juices computed tomography scans all c.t. scans to help determine what happened in syria every cadaver link to a police investigation is scanned and in this case police are puzzled. we get this i suspect says he thinks the victim pulled a gun 1st and then he pulled a gun but that seems at odds with the location of the entry will say that much is at the back of the victim's head not the front so we're trying to find out what really happened but see this. the procedure is called of a taapsee a virtual autopsy a c.t. scan shows a body's bones blood vessels and soft tissues it combines a series of x.

rays taken from different angles into the cross-sectional images or slices each slice is no sicker than a page dr tally finds the bullet in just a few seconds don't seem to hear form that you can see the nose here in front again you hear the eyes are up here and this is the brain isn't that i ski and if we move upward a little we see that this area of the brain shows evidence of bleeding and that's where the bullet is here in d.c. and. the result is clear. that's it gave me some of the evidence shows that the victim was shot from behind not in the front as the suspect claimed he had done after the victim drew his gun so the suspect statement was incorrect people fall short of the strange. dog in a normal autopsy the brain is removed from the skull before it's examined this makes it hard to determine the exact angle and location of a bullet. mixed a robot makes a 3 d.

skin of the body to capture all the surface injuries. the robot can also extract tissue. samples there will also be an m.r.i. in an effort to document everything the body can tell examine is when the sign fall east will be in cases where 3 d. scans could prove useful we run the full program here in zurich we actually have the 3 d. centers where police and forensic experts were closely together to solve the. 3 d. tech is helping swiss investigators check the angle of the bullet impact victim testimonies and marks found on a victim's body. dr talley co-founded the vertamae program in the late 1990 s. today the 3 d. scans are not only used to clear up crimes but accidents too like this victim who died while mountain climbing globe obviously this technology has become standard at a number of major institutions around the world is proud of the global recognition

of project is getting lost and so is our team global so these are all my canvas wondered how in germany nearly 400 cases of murder were reported in 2018 and. police managed to solve almost all of them. the clearance rate for residential burglaries is much lower than 201-711-7000 break ins were reported in germany police only made arrests in 18 percent of cases in the us now brooke police are hoping to stop burglaries before they even happen with the help of the predictive software pre-match. year after premier of all the software shows an increase in activity in the car could neighborhood so head over there and have a look around or hold. offices really catch burglars red handed but an increased

police presence in high risk areas could make burglars think twice about breaking into someone's home. we are result of for that we pay close attention to suspicious vehicles particularly those that are out of town license plates and we keep an eye out for suspicious individuals on the street by passing. some criticize that innocent people can also be caught. up in these preventive patrols that's one of the drawbacks of using the pre map software. after sunset offices hildebrand and graph top spot a vehicle that fits their profile. yet a pic of the old forms of it's gone out of town plates or the result seems there's a driver and one passenger let's have a closer look. better than that. was the pre-match prediction right now it's

time for the face to face police work. governed by looking at their driver's license and vehicle registration plates so shine. a check of recalls comes back negative for previous arrests and other problems. the officers look into the car's trunk. no stolen property here. loading sobbingly they had an angle grinder and some other stuff so they were probably doing construction around here either legally or illegally legal or illegal by. the rest of the shift is quiet perhaps the officers did manage to scare off some burglars just by patrolling the streets. there are about 300000

police officers in germany. and some of them have highly developed facial recognition skills. josh davis has developed a series of tests that can identify so-called super recognizers davis is one of britain's leading experts on forensic facial identification and he's been working with police departments to help them identify offices who may have these special skills. less than one percent of the population have super recognition ability it is very rare and which is why it's so important for policing and other security organizations. london police put together a team of the specialists in 2015 it's still not clear exactly how these people can remember all those faces it is possible but somehow the neurological processes of

super recognizers a some help different from us the rest of us in the world although davis is not a super recognizing himself he has a pretty good idea of how the process might work. so what we think that super recognizers may be able to do better than other people is to somehow. showing the view in their minds they can rotate faces in their mind so when they're watching c.c.t.v. footage where for instance you might see someone walking sideways across the screen in their mind perhaps they mentally rotating that face in order to be able to match the. in london the super recognizes have already helped solve thousands of crime cases. recently davis assisted munich police in finding officers within its departments who have this capability. i am sure every police force in germany

or anywhere else in the world has at least one super recognizer they just don't know they've got them yet they will solve crimes. one of munich places 37 super recognizes is this chief inspector we have been asked not to use her name she never forgets a face even if that face is only partially visible she demonstrates her skills in this test the goal is to find this man. so he's wearing a hat so some of his head is covered. get august that makes identification more difficult but it's definitely him. it's like a feeling and if i'm uncertain i look at the person's facial expression 5 particularly the ice. that's pretty unique. to super recognizers can also identify suspects from pixilated surveillance footage. the

unique police have yet to decide how to best employ their new found talented officers. thomas is in charge of the project he sees many possibilities. in how did you find him yes right here we've heard. your current including our recognizers could help in criminal investigations whenever pictures or videos are available whether the suspect has been identified by name or not and we have often become. munich police have already used this super recognizes during the october fest to track down pickpockets and they're also keeping an eye on crowds at football matches and christmas markets. on. this super recognise i can even remember faces she only saw once briefly 10 years ago. there is another

technique being used by police to solve crime one which some people oppose. detective renren t.m.r. helps solve a high profile murder case in the netherlands. this is column a quiet village in northern holland where on the 1st of may 999 a 16 year old girl was raped and murdered in a nearby meadow 9 was mariana fact struck. the case would change policing in the netherlands for ever light it would also be a turn. in point in the career of detective or in gemma with. him. i was found in a meadow nearby finke closer small little village mariana. was raped and murdered her throat was slit and it was a brutal scene to look up on. police found d.n.a.

evidence at the scene but it didn't match any of the profiles in their database. in 1999 dutch police were only allowed to use d.n.a. to determine sex and compare the sample to their database but although there hadn't been a match many local residents felt they knew who the killer was right by the meadow where mariana was found stood a center for asylum seekers. a lot of people from that area pointed their fingers at that asylum seeker center child that was a factor in this case faced with mounting public tensions the prosecutor ordered the 1st ethnicity test to be run on a d.n.a. sample in a crime case. d.n.a. told us actually that it was much much more likely that the perpetrator came from western europe as an origin then from the asylum she could have. the unexpected

d.n.a. result helped clear the asylum seekers suspect in this case but critics have expressed concerns it could lead to discrimination run takes a different view. you can prioritize based upon information through the d.n.a. that you are probably going to find them in the top 100 of those 10000. it wasn't until 2012 that marianas killer was finally identified and again it was d.n.a. testing that helped. cracked the case. basic research conducted by professor manfred kaiser had helped develop a new form of d.n.a. research known as genealogical testing case that is head of the department of forensic molecular biology at the university of russia. in many

imus case why chromosome d.n.a. tests were carried out in september 2012 in an effort to find any male relations to the killer. that money is a in this kind of d.n.a. profile analysis all you need is a sample from one male relative however far removed and that will give you the trail to track down your are known perpetrator. of. men living within a 5 kilometer radius of the meadow where mariana was found were asked for a d.n.a. sample around $8000.00 submitted their d.n.a. voluntarily but then something unexpected happened. i got a phone call was the 14th of november by the end of i they told me we have a match and there is something that you cannot describe. the killer it was a local farmer who had voluntarily submitted his d.n.a. he had hoped the test wouldn't work. if you did not would have given his d.n.a.

we would have found him anyway he was caught he was trapped. by the dish investigation to. critics one that d.n.a. tests are not always 100 percent reliable now physical appearance for instance can vary from what it says now d.n.a. and so false predictions can be made in the netherlands strict legal rules determined when d.n.a. tests could be used. in the movie shoot a little higher your mic. we return to the virtual murder investigation in munich. ringback does the shoe match the imprint left on the victim's head. go ahead and push it right into the skin.

we should take some exact measurements later. thank you michael but i think we've got a good match the past. 3 days scans allow investigators to return to the crime scene at any time every detail is recorded right down to the contents of the washing machine. this was a listen i will scan everything because a detail that we didn't notice at 1st or which seemed in significant may become important later on in the investigation that was described as. the victim's body can also be re-examined at any time thanks to this 3 d. print which can be kept long after the actual could has begun deteriorating all been buried. break up will now rush to report on whether the shoe sole fits the imprint on the victim's head he says it's rewarding to him to be able to help solve

a crime. macondo to do so that feeling of being able to help find the truth and clear up a case with our work and that's that makes me really appreciate my job nichols similar to the tomb. of course this wasn't a real homicide it was just a training exercise but 3 d. technology has helped munich police to clear several murder cases. new technology has brought about a revolution in law enforcement and the perfect crime may soon become a thing of the past.
