Authorities in Munich say the man who allegedly killed nine people in a mall shooting spree on Friday was “obsessed with shooting rampages” and had tricked people into visiting the mall using Facebook. Police and prosecutors held a press conference on Saturday to reveal some disturbing details about the suspect, identified as an 18-year-old German-Iranian from Munich. The suspect was found dead after the attack, having apparently killed himself. Police say he had hacked a young woman’s Facebook account and sent out messages urging people to come to the mall for a giveaway, apparently in the hopes of getting more victims. The shooter had acted alone and had no links to the Islamic State or other terror groups, police said. A day of mourning has been declared in the city and all public festivals planned for the weekend canceled.
