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.

Shane Prior, 34, shot the 30-year-old Cushing woman just before 10 p.m. Monday outside a Somerville Road house where she was staying with a friend since separating from Prior within the past month, according to an email from Stephen McCausland, spokesman for the Maine Department of Public Safety.

Prior hid on the property as he talked on the phone to the woman, who was sitting in her car in the driveway, McCausland said later Tuesday. He then allegedly grabbed her and forced her down the driveway, where he fired more than one shot, wounding her in the arm.

The couple’s two children, ages 6 and 10, were outside at the time of the shooting but did not witness it, McCausland said.

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

Prior then shot himself in the head in the truck. Later Tuesday, the office of the state medical examiner performed an autopsy on Prior and determined he died of a self-inflicted gunshot to the head, McCausland said.

Madore was not wounded. He has been placed on administrative leave with pay while the Maine attorney general’s office investigates the incident, as is standard procedure.

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

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