A Portland man has been indicted on charges that he tried to run down a trooper along the Maine Turnpike. Matthew Cole was indicted Friday on charges of eluding an officer, criminal speed, reckless conduct and violating conditions of release. Police say the 23-year-old Cole was driving an unregistered car on the turnpike on Sept. 15 when Trooper Kyle Wells tried to pull him over. Police say Cole sped off and crashed his car near Exit 42 in Scarborough. The trooper was outside his vehicle when police say Cole began backing up toward him. Police say the trooper fired at Cole’s car and Cole was not injured.
