Police are looking for an armed robber who struck a Marathon station in Dowagiac Monday night. Dowagiac police say the suspect walked into the gas station on Spruce Street around 10:40 p.m. flashing a handgun. He made off with the cash from the register, as well as a customer’s wallet. The suspect was wearing a mask and a hood at the time, along with dark clothing. He’s described as being about 6’1 and 200 pounds. A search for him with a police K9 didn’t turn up anything. Anyone with information on the crime is asked to call the Dowagiac Police Department.
