In order to solve an old crime, Japanese police have created a 3D model of the crime scene, which took place in Tokyo 13 years ago. In late 2000, a family was murdered in their home, but so far the police had failed to identify any suspects. With the use of 3D printing, another dimension could be added to the search for the perpetrator.
Already three years ago, the Tokyo Metropolitan Police Department have purchased 3D printers for their investigations and it’s not the first time they used 3D printers to solve a crime. Earlier this year, they arrested a member of Aum Shinrikyo, called Katsuya Takahashi, who was on the run from police for 17 years.
Right now, they 3D printed the two story house crime scene on a 1/28 scale model using a Selective Laser Sintering (SLS) 3D printing machine. Watchers are able to remove the roof of the model in order to take an accurate look at the inside of the model.
The useful thing about 3D printing a crime scene reproduction is that it adds depth to the model. The helps viewers to visualize the crime scene on a more punctual level than they would do whilst watching photos of paper drawings. It already worked out pretty well for the police department, because they received as many as 11,800 clues related to this case.
