PSFocus writes: On Saturday morning (april 8th) the 24 year old Tristan van der Vlis shoots himself through his head, but not before he killed six innocent people and injures 10 people and more. The shooting happened in a shopping mall in Aphen aan den Rijn, and the shooter used different guns, but his main killing weapon was a machine gun. He was a young kid with a psychological problem, had no friends and (of course?) he’d played a lot of violent videogames. His uncle said that he locked himself up to play violent videogames. FBI Profiler Greg O. McCrary, said that playing violent videogames, fits the profile of a mass murderer.
