State police are asking for the public’s help in locating a Detroit man who they say fled on foot from police Saturday night after leading police on a car chase in Palmyra. According to information released by the Maine State Police late Sunday afternoon, Trooper Tyler Maloon attempted to stop a vehicle driven by Steven Dumont, 36, of Detroit, for a defect. Instead of stopping, state police say Dumont drove off down Route 100 and on to Route 220 into Detroit before stopping behind a home.
