A convicted felon from Bangor who threw two loaded assault-style rifles from a car as he led police on a high-speed chase in 2012 was sentenced Wednesday in federal court to serve 18 years in prison.

Lauren MacArthur, 29, who had been convicted of at least three violent felonies before that incident, was sentenced in U.S. District Court in Bangor as an armed career criminal. He faced a mandatory minimum of 15 years.

MacArthur was driving southbound on Interstate 95 in Old Town on Jan. 20, 2012, when he sped away from a state police trooper who tried to stop him for having a dirt-covered license plate. The “prolonged chase” reached speeds of 90 mph through Orono and back north to Milford on Route 178 before a trooper rammed his vehicle off the road. The trooper continued chasing MacArthur on foot and tackled him as he tried to get away, according to court records.

Police recovered two rifles that MacArthur had thrown from the car, a Colt Model SP1 and an American Arms Model AKY39, which they determined had been stolen from a home in Medway, court records say.

MacArthur pleaded guilty on Nov. 26, 2012, to possession of a firearm by a felon and possession of stolen firearms.

Judge John Woodcock Jr. also sentenced MacArthur to serve five years of supervised release after he completes his prison term.
