JEFFERSON, Maine — A Cushing man shot and wounded his ex-girlfriend before a police chase that ended when he shot himself in his truck Monday night, according to state police.

At approximately 10 p.m., Shane Prior, 34, shot his former girlfriend, a 30-year-old Cushing woman, outside a Somerville Road house where she was staying, Stephen McCausland, spokesman for the Maine Department of Public Safety, said in a release.

The woman was taken to Miles Memorial Hospital in Damariscotta for treatment.

Troopers headed to the scene of the shooting spotted Prior’s truck and chased him about three miles to Route 32. There, police say Prior stopped his truck and shot at Maine State Police Sgt. Jason Madore, who returned fire.

Prior then shot himself in the head in his truck, according to McCausland.

Madore was not wounded, and has been placed on administrative leave with pay as the Office of the Maine Attorney General investigates the incident, as is standard procedure. An autopsy on Prior’s body will take place at the Office of the State Medical Examiner.

Route 32 was closed until just before 6 a.m. Tuesday, McCausland said.
