Rebecca Ann Rule-Cowles, 51, of Port Angeles was found dead at her home on the 300 block of Whidby Avenue on September 28, 2024, from multiple gunshot wounds. The primary suspect is 26-year-old Marquise Gregory Hagans-Moore, who shared the residence and turned himself in to Tacoma police on September 29, 2024, reportedly confessing that he had killed his roommate.

According to reports, the shooting followed an argument after Hagans-Moore brought two relatives to stay at the house following a family tragedy. Rule-Cowles had been hosting a gathering and later asked Hagans-Moore and the children to leave. Hagans-Moore allegedly told a family member he doesn’t remember what happened next, only that he emptied the clip on her; the victim was said to have been shot 17 times. He drove the children to Tacoma and left them at a mall in Olympia before surrendering.

Hagans-Moore was charged in Clallam County Superior Court with second-degree murder with domestic violence and firearm enhancements. Court appearances included reports of agitated, threatening behavior and an ordered competency evaluation. Investigators noted he was subject to domestic violence protection orders that required weapon surrender, and a handgun was found at the scene; the Washington State Patrol Crime Scene Response Team was assisting processing the residence.
