According to a post by sueddeutsche.de (the newspaper with the fastest and most accurate info on the OEZ shooting) from a few minutes ago, today, July 24, 2016 the Munich shooter has bought the pistol he used during the rampage on early Friday evening over the Darknet. The Glock 17 had been previously used in theatre as a prop and has later been reworked to be used as a regular weapon, according to the newspaper. The pistol has a Slovakian stamp on it. It was fired from 57 times during the shooting on Friday.
The darknet (or dark web) is an overlay network that can only be accessed with specific software, configurations, or authorization, often using non-standard communications protocols and ports. Two typical darknet types are friend-to-friend networks (usually used for file sharing with a peer-to-peer connection) and privacy networks such as Tor.
On Friday, July 22, 2016 a shooting occurred in the vicinity of the Olympia shopping mall. Ten people, including the gunman, were killed and 35 were injured. The shooting took began at a McDonald's restaurant near the shopping mall. Officials identified the lone gunman as an 18-year-old German of Iranian descent from Munich who later committed suicide.
According to latest reports, most of the victims were young people from Munich (among them three Kosovo nationals, three Turkish nationals and one Greek national) the oldest being a 45-year-old woman. Latest reports indicate that the shooter was inspired by the attack which happened 5 years ago in Norway also on July 22.
