Milwaukie police say a 46-year-old Portland man is behind a one-man crime spree that happened last month.
Officers tracked down Mark Siebenmorgen, 46, at his home in Portland last week and took him into custody.
Police said Siebenmorgen assaulted a man at a Milwaukie TriMet bus mall on Oct. 21 and minutes later was spotted jumping on the hood of a parked car with a driver inside.
Less than an hour later, police say Siebenmorgen began throwing rocks at a woman near Milwaukie Market Place on Oak Street. That woman suffered minor injuries.
When officers searched for the suspect, they weren’t able to find him, but they eventually learned he was living in an apartment on Southeast Stark Street in Portalnd.
Siebenmorgen was arrested last Thursday and booked into the Clackamas County Jail on charges of criminal mischief, assault and menacing.
