State Police Investigating Fatal Crash Involving Motorcycle on Route 495 in Chelmsford

Massachusetts State Police are investigating a crash between a car and motorcycle yesterday in Chelmsford that caused the death of the motorcycle operator and serious injuries to the passenger.

Preliminary investigation by Trooper Kenneth Quigley of the State Police Barracks in Andover indicates that at approximately 3:30 p.m. a 2016 Mercedes-Benz C450 sedan and a 2007 Yamaha XVS were being operated in the left lane of Route 495 northbound. Evidence indicates that the motorcycle struck the rear of the car.

The motorcycle operator, David A. Mains, 48, of Raymond, Maine, was transported by medical helicopter to Massachusetts General Hospital, where he was pronounced deceased. His passenger, a 48-year-old Raymond, Maine woman, was transported by ambulance with serious injuries to Lowell General Hospital, and then was transported to Tufts Medical Center for further medical care.

Neither the driver of the Mercedes, a 56-year-old Andover woman, or her passenger, a juvenile, were injured.

Preliminary investigation suggests the crash occurred after the Mercedes slowed due to traffic congestion. The crash remains under investigation by Troop A of the Massachusetts State Police with assistance from the State Police Crime Scene Services Section and the State Police Collision Analysis and Reconstruction Section. The results of the investigation will determine whether any charges are sought.

As a result of the rescue response and crash investigation, two northbound lanes were closed for one hour and 25 minutes.

No further information is being released at this time.
