QUINCY, Mass. — Massachusetts State Police say a driver fleeing a police stop was killed when his vehicle crashed through a sea wall and ended up on a beach.

Police say 50-year-old Peter Boylan was pulled over in Quincy around 9 p.m. Monday for motor vehicle violations. He then fled the stop at high speed while the trooper was processing his information.

While fleeing, the driver sideswiped one vehicle and then crashed into another before rolling over the seawall and dropping about 10 feet to the beach.

Boylan was pronounced dead at the scene. A 27-year-old woman in his car was ejected and transported to a hospital.

A driver of another involved vehicle was also taken to an area hospital. The sideswiped vehicle’s driver was not injured.
