our viewership. my instructions occupied the city center in 2000. president due to his response was. this is not the kind of freedom that we are. how did not become a gateway to islamize terror. an exclusive report from a destroyed city. in the sights of fire starts may 20th on g.w. . this investigator is using virtual reality technology to digitally revisit the scene of america. 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. i mean you wish this. investigation. and techniques are transforming law enforcement. this being a murder and rough break and florencia 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 spare work for another special unit. the crime scene has been recreated and actor is lying in. kitchen in the same

position and location as the victim was found in the resigns of a struggle and of alcohol consumption break and she will begin gathering evidence but they won't be using cameras and measuring instruments. so let's use the structured like 3 d. scanner this looks a bit like a shoe print as we reported. the scanner captures the injuries to the victim's head in an accurate and true to scale 3 d. image the equipment costs 80000 euros and it can record every single visual detail of a crime scene. look what. 10 years ago crime scenes were only photographed it now we also use the laser scanner for serious felonies 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 detailed 3 d.

scan is stored in an archive so that police can review it at any time. break and his team record about 60 crime scenes a year mostly felony crimes. the offices need for scans to capture this room in the process takes only 12 minutes. discovered a candidate this scanner can't see through that table was pushing me so i have to move it to get as complete an image of the room as possible just looking to. break 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 large 3 day scan which is accurate to $100.00 micro mage's 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. less often see 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 from. what we're hoping is that we'll be able to compare the marks on his head with the suspects shoes. 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 it shoeless eyelets an important fact that could prove useful when identifying a suspect the fact that it is now possible to digitally record an 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 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 burglar is a particularly active jaring long winter nights but the offices in broke have a new tool. 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. 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 also told our car that is it. was one of the stretch between house numbers 140 to 150 and was so that's where we'll focus our patrols tight i mean i have a lookout for any vehicles from the region criminal groups from there have been working in and around the city along quite awful. hildebrand and office over a bare ground tough 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 officers prevent break ins. as i fear to have

this neighborhood has a large number of single family houses either 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 a 2nd property also because they know the name. board the software capitalize 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. because it could attack and he thought of the burglars alist case is 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 crossing or. the yellow areas on this map indicate neighborhoods that are particularly at risk the break ins the software identifying the areas means police can geographically focus their prevention efforts. but will the calculated predictions prove correct the officers will soon find out. and meanwhile the investigators in munich have assembled a 3 d. scan. break and his team found bloody footprints in the kitchen with the help of the chemical luminol luminol reacts with iron found in blood causing a short lived blue glow. that they can see here that will work well for a 3 d.

comparison of the 1st 2 to. graft breakers college degree is in geographic information science that has 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. luminol 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 could give an issue that might have been involved we can compare it with aluminum friend. you couldn't do that before the mission location.

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. can you measure the distance from the table leg. to his head. 7 centimeters. ok if 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 like different types of experts to be able to use our virtual crime scenes in the future the medical examiners

could carry out tests on blood stained patterns and ballistics could use our virtual last 2 in on some version lead to or 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 hour after 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.

words of the institute of forensic medicine at the university of zurich preparing to conduct an autopsy on the body of the shooting victim. there will be no surgery in the traditional sense this is going to be a virtual autopsy. forensic specialist dr michelle tully uses 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 a puzzled. we do 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 victims had not the front so we're trying to find out what really happened to. this. the procedure is called of a topsy 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 will 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. to us again it's going to create evidence shows that the victim was shot from behind and not in the front as the suspect claimed he had done after the victim drew is got so the suspect statement was incorrect people fall short of 40 storage. 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 day centers where police and forensic experts were closely together to solve the. 3 d. tech is helping swiss investigators check the angle of a bullet impact victim testimonies and marks found on a victim's body. dr talley co-founded the vertamae c. 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 this suit i'm proud of the global recognition our project is getting lost and so is our team global so these are on a canvas wondered out in germany nearly 400 cases of murder were reported in 2018. police managed to solve almost all of them. the clearance rate for residential burglaries is much lower in 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 prematch. you have to preserve all the software shows an increase in activity in the car neighborhood so head over there

and have a look around have more. officers 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. 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. up to sunset offices hildebrand and graph hot spot a vehicle that fits their profile. pic of wheels falls on it's got out of town plates it was overseas and it seems there's a driver and one passenger let's have

a closer look of it other than that. was the pre-match prediction right now it's time for the face to face police work. now and i would like them for a driver's license and vehicle registration clearance so shy. 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. the. loading starting the 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 recognizes. this is one of britain's leading experts on forensic facial identification and he's been working with police departments to help them identify offices he may have 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 recognizer 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're mentally rotating that face in order to be able to match them. 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. 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 eyes. that's pretty unique. and 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 graber is in charge of the project he sees many possibilities. and how did you find him yes right here where. you're currently in including our recognizers could help in criminal investigations whenever pictures or videos are available whether the suspect has been identified by name or not. we have often become. merely 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. this super recognize

a 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. helped 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 her name was mariana that struck. the case would change policing in the netherlands forever light it would also be a turn. one point in the career of detective. is that given that. him money i was found in a meadow new about thing close with small little bit which. 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 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 so 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. do you know told us actually that it was much much more likely that

the perpetrator came from western europe as an origin then from the asylum seekers 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 kayser is head of the department of forensic

molecular biology at the university of russia dom. in many imus case white chromosome d.n.a. tests were carried out in september 2012 in an effort to find any male relations to the killer. that money in this kind of d.n.a. profile analysis all united 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 it was the 14th of november by the end of i they told me we have a match and that is something that you cannot describe. the killer was

a local farmer who had voluntarily submitted his d.n.a. he had hoped the test wouldn't work. if he did not would have given his d.n.a. would have found him anyway he was caught he was trapped. by the you will this. investigation talk. critics we won that d.n.a. tests are not always 100 percent reliable our physical appearance for instance can vary from what it says in our d.n.a. and so false predictions can be made in the netherlands strictly legal rules determine when d.n.a. tests could be used. in the movie she saw a little higher your mic. we return to the virtual murder investigation in munich. does the shoe match the imprint left on the victim's head. go ahead and push it right into the skin.

on our own or we should take some exact measurements later. thank you mark 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 we 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 these 3 d. print which can be kept long after the actual cadaver has begun deteriorating 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 for him to be able to help solve a crime a. man cannot produce and 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 because 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 clues 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.
