On the morning of Aug. 30, 2021, Dewhurst called a suicide hotline and revealed he was armed and planning to fatally shoot himself. He also said he intended to fight law enforcement and was preparing for a "gunfight with police."
A Beaverton Police Department officer spoke with Dewhurst on the phone to assist, and while they were talking, Dewhurst reportedly admitted that he killed his roommate, 43-year-old Rocky Harkins.
According to the district attorney’s office, officers successfully negotiated with Dewhurst to leave his apartment, and they apprehended him without incident. During a search of his home, police found Harkins dead from a single, "close-range" gunshot wound. Officers also recovered two Glock handguns and an AR-15 rifle, along with a tactical vest with several loaded rifle magazines and more than 150 rounds of ammunition.
Further investigation revealed that Dewhurst put together the weaponry after shooting Harkins but before he called the suicide hotline.
In court, Dewhurst argued that he shot the victim in self-defense.
