LAMOINE, Maine (AP) — State police say a Maine man had exhibited erratic behavior before using two guns to kill his father and uncle in Lamoine, Maine.

State police say family members told investigators that 27-year-old Leon Tilden appeared to be depressed and had a number of guns in his cabin. They said he’d been staying up late, shooting at raccoons and other animals in the middle of the night.

Autopsies showed his father, Robert Tilden, and his uncle, Russell Pinkham, both 50, died from multiple gunshot wounds early Tuesday. Leon Tilden was later shot to death in a confrontation with state police.

Steve McCausland of the Maine Department of Public Safety said investigators have yet to determine the motive and may never know what caused Tilden to kill his father and uncle.
