Investigators searched the unnamed German-Iranian man’s home overnight and found a considerable amount of literature about mass killings, including a book titled Rampage in Head: Why Students Kill, but no evidence that he was linked to extremist groups such as the Islamic State. “(He) was obsessed with shooting rampages,” Munich’s police chief Hubertus Andrae told reporters.
Investigators also found evidence that the Munich-born suspect had suffered from psychological problems and received treatment, but details were still being confirmed, said Munich prosecutor Thomas Steinkraus-Koch.
The attack in the Bavarian capital sparked a massive security operation as authorities, already on edge after the recent attacks in Wuerzburg and Nice, France received witness reports of multiple shooters carrying rifles shortly before 6 pm.
Eight hours later police declared a “cautious all clear,” saying the suspect was among the 10 dead and that he had likely acted alone. German Chancellor Angela Merkel was due to chair a meeting of her government’s security Cabinet on Saturday. At an address on Dachauer Strasse that was searched by police early Saturday, a neighbour described the suspect as very quiet. “He only ever said ‘hi’. His whole body language was of somebody who was very shy,” said Stephan, a coffee shop owner.
