Thomas James Walter-Thompson, 44, was killed in Chambersburg, Pennsylvania on May 1, 2026. Police say Walter-Thompson placed a call to the Pennsylvania State Police to report a suspicious person; while troopers were en route a second call reported a man in camouflage firing a weapon and fleeing in a red van. Officers found Walter-Thompson on the 800 block of Lincoln Way West with multiple gunshot wounds and he was pronounced dead at the scene.

Investigators identified 28-year-old Sage Sebastian Morrison of Chambersburg as the person of interest and took him into custody at his residence. Police allege Morrison went to Walter-Thompson’s home to confront him about a personal matter, had been watching him for three days, retrieved a gun from his grandparents’ house, and, as Walter-Thompson returned, an argument ensued and Morrison allegedly shot him multiple times. The Franklin County District Attorney’s Office approved charges of first-degree murder and stalking, and a preliminary hearing was scheduled for May 12, 2026.

If anyone witnessed activity on Lincoln Way West that day or knows more about interactions between the two men, please come forward with information.
