@Walter Hinteler,
Several other unsubstantiated rumors punctuated a chaotic evening in Munich, including multiple reports of secondary shootings at key sites in the city, which proved not to be true. Similarly, conflicting reports on the shooter, what he was wearing, and what he might have said at the scene circulated.
For a time, police had worked on the assumption of "up to three" shooters; eyewitness reports forced police to presume that more than one person was involved. Two people had left the scene at speed in a car, prompting suspicion, but police investigated them: "They have nothing to do with the incident," police chief Andrä said.
"The motive, and the background of the crime are still totally unclear, the investigators are working full tilt and will continue into the night," Andrä said, adding that the process should move relatively quickly, as police were confident that they had identified the suspect. Defining whether the shooting was a case of somebody running amok, or an act of terror, would require more information on a possible motive, he said.
