A Minneapolis man has been charged with multiple felonies for a bank robbery in southwestern Minnesota this week, as authorities investigate whether he is responsible for dozens of other bank robberies in the state. 49-year-old Mark Wetsch was charged Thursday in Nobles County with aggravated robbery, terroristic threats and theft for Tuesday’s robbery of the Rolling Hills Bank in Brewster. The robber reportedly used a fake gun to steal $1,800. The suspect was arrested by St. Peter police after he was seen in a vehicle believed involved in the holdup. An FBI spokesperson says authorities continue investigating whether the suspect is the serial bank robber dubbed the “Man in Black” responsible for bank robberies around the state, including in St. Peter. Wetsch remains in jail with bail set at $300,000.
