MUNICH, July 23 (Xinhua) -- German investigators have found "documents about amok-runs" during a search of the residence of the shooter, who killed 10 people and injured 27 in a shooting attack in southern German city of Munich on Friday evening.
The perpetrator of the Munich shootout has no relation to the Islamic State (IS), Munich police chief Hubertus Andrae on Saturday told a press conference, adding that the search of the room of the 18-year-old revealed that he had dealt intensively with killing spree.
According to the police, the perpetrator shot with a 9-millimeter calibre pistol that he had probably obtained illegally, while 300 cartridges were found in his backpack. However, it is still unknown where he got the gun and the money for it.
The perpetrator was not in the police register. However, he was allegedly depressed and was under psychiatric treatment, which fits with the other findings of the crime, according to investigators.
It has yet to be verified whether the offender has deliberately shot foreigners, said the police.
The shooter held dual citizenship of Germany and Iran and had lived in Munich for more than two years, said Andrae in an earlier press conference.
