Deputies wounded during emergency approach
A woman sought help from a neighbor after being shot, telling the neighbor that her brother was responsible, KOMO reported. She was hospitalized with injuries authorities did not consider life-threatening. Authorities discovered that the suspect had an active felony warrant and believed people inside the home might still be in danger.
As SWAT officers approached to enter the house on an emergency basis, someone inside opened fire, critically wounding Acheson and Perry. FOX 13 Seattle reported that other officers brought the deputies to safety and provided emergency medical care. Neither deputy survived.
The Spokane County Medical Examiner named the suspected gunman as Ryan Larsen, 37, and determined that he died of a gunshot wound to the head. The Spokesman-Review reported that the wound was self-inflicted.
The medical examiner also identified the two other people killed at the property as Suzanne Larsen, 72, and Rebecca Larsen, 45. Both suffered gunshot wounds to the head. According to The Spokesman-Review, Suzanne was the suspect's mother and Rebecca was his sister.
The Seattle Times and The Spokesman-Review described the deputies' deaths as Washington's deadliest law enforcement shooting since 2009. That year, four Lakewood police officers were assassinated at a coffee shop in Parkland before their shift.
Acheson's law enforcement and military service
Acheson was 35 at the time of the shooting, according to The Spokesman-Review. His law enforcement career included service with the Washington State Patrol from 2014 to 2022, followed by his move to the Spokane County Sheriff's Office in 2022. He worked as a SWAT sniper and leaves a wife and two children.
The sheriff's office said Acheson enlisted in the Washington Army National Guard in 2011 and attained the rank of sergeant. Assigned to the 81st Brigade's 1-161st Infantry Battalion, he served in Poland in 2021-2022. His military experience also included the Sniper Course in 2017 and participation in Army sniper competitions.
Perry's SWAT, K-9 and National Guard roles
Perry, who was 29 at the time of the shooting, according to The Spokesman-Review, joined the sheriff's office in 2020. He served on its SWAT team from 2022 until his selection as a K-9 deputy in 2025, the agency said. His K-9 partner was Brego.
Perry's National Guard service began in 2017. The sheriff's office said he became a captain and military intelligence officer with the 81st Brigade's 1-161st Infantry Battalion. He received two Army Commendation Medals and an Armed Forces Service Medal.
He leaves his wife and two children, with a third child on the way, according to the sheriff's office. MyNorthwest reported that his family decided to donate his organs after the shooting.
State tribute and family assistance
The sheriff's office remembered both deputies for risking their lives to protect strangers. In their memory, Gov. Bob Ferguson directed Washington state facilities to fly flags at half-staff through the close of business on Monday, Nov. 9, 2026, The Seattle Times reported.
The SCOPE/SCSO Memorial Fund is collecting contributions toward the families' funeral expenses, according to The Spokesman-Review. Donations are accepted at any Canopy Credit Union branch, by check at the sheriff's office or through Venmo at @SpokaneSCOPE. The sheriff's office said state funds cannot be used for those expenses.
