The sarin attack on the Tokyo subway on March 20, 1995 was an act of domestic terrorism perpetrated by members of Aum Shinrikyo.
In five coordinated attacks, the perpetrators released sarin on several lines of the Tokyo subway, killing thirteen people, severely injuring fifty and causing temporary vision problems for nearly a thousand others.
Last June, after 17 years on the run, the last wanted member of Aum Shinrikyo, Katsuya Takahashi was arrested at a manga cafe in downtown Tokyo. In an interview with ANN news Japan last week, Tokyo Metropolitan Police Department revealed that during the investigation they created a 3D face model from Takahashi’s photo with help of 3D printing. The 3D model was then published through ANN.
The intention was to collect new information with this realistic 3D printed model, but shortly after that, Takahashi was arrested.
The police department was introduced to 3D printers about three years ago, and 3D printer were mainly used to reproduce the 3D models of crime scene and weapon. This was the first time 3D printer was used to make 3D face model. In the future, the Metropolitan Police will also use 3D printed models as materials for jury trial.
Takahashi was the bodyguard for the Aum Shinrikyo doomsday cult and his role in the attack involved driving a fellow member to the train station.
