Domestic violence call prompts emergency response
Deputies first responded at about 2:25 p.m. on Nov. 3 after a woman reported that she had been shot at a residence near Spangle, south of Spokane. The woman was taken to a hospital with injuries authorities described as apparently non-life-threatening. Investigators learned that the suspect had an active felony warrant and might have access to additional weapons.
Because other victims might still have been inside the home, authorities requested a SWAT response. The situation involved a suspected domestic violence shooting, a potentially armed suspect and concern for possible hostages, requiring officers to coordinate a high-risk rescue operation.
Deputies enter home amid hostage concerns
Parker Perry, a K-9 deputy, joined the team approaching the residence at about 3:15 p.m. with his dog, Brego. The sheriff’s office said Perry forced his way into the home as officers moved to determine whether anyone inside needed immediate protection.
Mason Acheson also took part in the operation. He served as a SWAT sniper and was assigned to help protect teammates entering dangerous scenes. The deputies moved toward the residence because authorities believed other people could be trapped or injured inside.
Fatal ambush and emergency medical response
Gunfire from inside the home struck Perry and Acheson. Their teammates returned fire, pulled both deputies to cover and began treating their wounds. Medical helicopters were requested, while sections of Interstate 90 and U.S. Highway 195 were closed to help speed the injured deputies to medical care.
Acheson died after reaching the hospital. Perry remained on life support while arrangements were made for organ donation. The sheriff’s office said he would continue serving others through the gift of life. Each deputy left behind a wife and two children, and Perry and his wife were expecting a third child.
Suspect and two relatives found dead
After the shooting, Spokane police took over the scene, and SWAT teams from Spokane and Kootenai County were called to assist. A drone sent into the residence located the suspect dead, according to the Washington State Patrol.
The Spokane County medical examiner identified the suspect as Ryan Larsen, 37, and determined that he died from a self-inflicted gunshot wound. The examiner also identified Suzanne Larsen, 72, and Rebecca Larsen, 45, as having been killed. A family obituary identified them as Larsen’s mother and sister. Sheriff John Nowels described the incident as a tragic day that affected many families.
Deputies remembered for military and public service
Mason Acheson enlisted in the Washington Army National Guard in 2011, rose to sergeant and served in Poland from 2021 to 2022. He received three Army Commendation Medals. Before joining the Spokane County Sheriff’s Office in 2022, he spent eight years as a Washington State Patrol trooper and firearms instructor.
Parker Perry joined the sheriff’s office in 2020 and served on its SWAT team for three years before becoming a K-9 deputy in 2025. He joined the Army National Guard in 2017, became a captain and worked as a military intelligence officer. He received two Army Commendation Medals. Both deputies served in the same Washington Army National Guard infantry battalion.
Federal and state officials honored the deputies, while Gov. Bob Ferguson ordered flags at state facilities lowered to half-staff on Nov. 9. A community policing organization is accepting donations for funeral costs, with remaining funds directed to the families. The sheriff’s office said the families requested privacy.
