A 34-year-old Cushing man took his own life Aug. 15. after a short police chase in Jefferson after police say the man shot a woman in the arm.

Shane Prior shot and killed himself after wounding a 30-year-old woman, also of Cushing, outside a home she was staying at on Somerville Road, according to Maine Department of Public Safety spokesman Stephen McCausland.

The State Medical Examiner’s Office has determined that Prior died from a single self-inflicted gunshot wound to the head and the death was ruled a suicide.

State Police say Prior was hiding on the property in Jefferson as he talked on the phone to his former girlfriend, who was sitting in her car in the driveway.

He then 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 10 and 6, were outside when the shots were fired but did not witness the shooting.

The two had been a couple since 2000 and had separated within the past month. She was living with a friend at the Jefferson home where she was shot.

Troopers responding to the domestic violence shooting discovered Prior driving his pickup leaving the scene and chased him about three miles onto Route 32, where he stopped his truck and fired a shot at a trooper, who returned fire. Prior then shot himself while inside the truck, police said.

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

The trooper — Sgt Jason Madore —  was not injured and has been placed on administrative leave with pay while the Maine Attorney General's Office investigates the police involvement with the shooting. That is standard for all police-involved shootings in Maine, McCausland said.

Madore is a 12-year veteran of the State Police assigned to Troop D in Augusta, and a longtime member of the crisis negotiation team.

Route 32 was closed during the night and is now reopened.
