BRIDGTON – A Bridgton businessman and former Cumberland County sheriff’s deputy was listed in critical condition Tuesday night with injuries sustained when his motorcycle struck the back of a car Monday on Route 117, officials said.

Eric “Rick” Marston, 60, of 8 Cottage St. in Bridgton was being treated at Central Maine Medical Center in Lewiston after the collision involving Kara Thurlow, 34, of 867 Norway Road in Harrison, Bridgton police officer Donald “Mac” McCormick said Tuesday night. A nursing supervisor said Marston’s condition was critical.

Marston owns Pegalegpete’s Leather at 261 Main St.

He was driving his Ural 2007 motorcycle with sidecar south toward the center of town about 2:30 p.m. when it struck the back of Thurlow’s 2006 Dodge Stratus sedan that was stopped to make a left turn, McCormick said.

Marston was thrown from the motorcycle and was not wearing a helmet, he said. He was taken to Bridgton Hospital by United Ambulance and flown from there to Lewiston.

Thurlow went to a hospital on her own for examination of apparent minor injuries, he said.

The car was totaled; the bike had minimal damage.

Sgt. David Hall of the Sheriff’s Department reconstructed the accident, which remains under investigation, McCormick said. Also assisting at the scene was Bridgton Fire Department.
