Authorities in Muenster, Germany, say the driver who crashed into a crowd of people Saturday was well-known to police.
A German prosecutor said the man had run-ins with police regarding property damage, fraud and a hit-and-run, but all charges were dismissed each time.
Authorities say they "have no indications that there is a political background" to the crash, though, and they're still not certain about a motive.
The crash killed two people, and the driver killed himself not long after. Some of the 20 people injured in the crash are still in life-threatening condition.
