A 21-year-old man was killed in a car accident on Route 1A in Hampden after leading police on a brief chase that began in Bangor Monday afternoon, according to police.

Hampden Director of Public Safety Joseph Rogers said Matthew Cynewski, 21, of Belfast died en route to Eastern Maine Medical Center in Bangor as a result of injuries he sustained in the crash.

Rogers said Cynewski initially caught the attention of police at about 3:30 p.m. Monday, after several police agencies received bulletins regarding a Jeep that was operating erratically just north of Bangor.

“The Jeep was observed in Bangor later in the afternoon by a Bangor police officer,” said Rogers.

The officer pursued the vehicle, but the driver — who was later identified as Cynewski — did not stop and instead led the officer on a high speed chase that headed into Hampden, Rogers said.

As the pursuit moved onto Route 1A, said Rogers, Cynewski reportedly sideswiped a vehicle that was being operated by 62-year-old Lorraine Frawley of Hampden. Frawley, who Rogers said was not hurt in the accident, was stopped in traffic waiting to turn left into a driveway when Cynewski approached from behind and struck the driver’s side of Frawley’s vehicle as he passed by.

Rogers said from there, Cynewski’s Jeep struck a tree.

The accident remained under investigation Tuesday, said Rogers.

Police do not know why Cynewski did not stop for police.

“There are no warrants out for him,” said Rogers.

The Hampden Police Department is heading up the investigation, and the Orono Police Department is assisting with the accident reconstruction, Rogers said.

According to his obituary, Cynewski attended Belfast schools and was employed in Belfast.
