Diane Michele Perron, 76, was found shot to death inside her Gig Harbor home on October 3, 2020. Officers responding to a welfare check at her residence in the 6500 block of Valley View Drive Northwest discovered her body after her front door had been forcibly kicked in. The Pierce County Medical Examiner ruled her death a homicide from multiple gunshot wounds.

Investigators say attention quickly turned to a neighbor, Mark Allen Erisman. Neighbors reported he had a history of mental health problems and had become increasingly agitated with Perron, accusing her of using electronic devices to frighten wildlife from his yard. In the days before the killing he was heard yelling and making threats; deputies and a mental health co-responder had visited him. Security camera footage reportedly shows a man approaching Perron’s house with a handgun, shooting out the camera, kicking in the door, and shooting her multiple times.

Beyond that sequence, details about motive and what prompted the fatal escalation remain limited. If anyone knew Diane Perron, her routines, or saw suspicious activity around Valley View Drive Northwest in late September or early October 2020, please share what you know.
