Two Spokane County sheriff’s deputies died after a gun wielding suspect opened fire during a desperate attempt to rescue a woman who had been shot in the chest. Deputies Mason Acheson and Parker Perry were struck Tuesday after entering a home on Smythe Road.
Police said the suspect, Ryan Larsen, 37, had shot his mother and sister inside the residence before firing on the responding officers. The attack left two families grieving [1] deputies who had served both their community and the military.
Spokane County Sheriff John Nowels announced Friday that Acheson had “lost his valiant fight and succumbed to his injuries last night.” Perry remained on life support in critical condition while surrounded by his family before also succumbing to his wounds.
Perry was an organ donor, and Nowels said arrangements were being considered. “He will continue to serve others with the gift of life,” the sheriff said.
Perry is survived by his wife and two children, with a third child on the way. Acheson was remembered by a family fundraiser as the devoted husband of Hannah and a loving father to their two young boys.
“Although we know our Deputies knew the risks, they bravely moved toward danger to protect others they did not know,” Nowels said. He described Acheson and Perry as true examples of selfless service and dedication.
RIP. Washington Deputy Sheriff Mason Acheson, who gave his life in the line of duty, is the 80th officer lost in 2026.
Deputy Sheriff Mason Acheson, 35, succumbed to gunshot wounds he received when he was ambushed while responding to a domestic violence call on November 3, 2026.
Around 2:25 p.m., deputies responded to a female victim stating she had been shot at the 18700 block of South Smythe Road in Spangle. The SWAT team was called after a drone discovered a deceased body in the yard, and deputies realized the suspect had two felony warrants. At 3:15 p.m., the SWAT team and deputies attempted to enter the home when they were ambushed. A man inside the residence fired upon them, and a gunfight ensued. The suspect was later found deceased inside the residence from a self-inflicted gunshot wound.
Deputy Acheson and Deputy Parker Perry were critically wounded. Deputy Acheson passed away the next morning at Providence Sacred Heart Medical Center. Deputy Perry passed away on November 7th.
Deputy Acheson enlisted in the Washington Army National Guard in 2011 and attained the rank of Sergeant. He was assigned to the 81st Brigade, 1st Battalion, 161st Infantry Regiment. He deployed to Poland in 2021–2022, completed the Army Sniper Course in 2017, and participated in Army sniper competitions. His military awards included three Army Commendation Medals, an Army Achievement Medal, three Army Reserve Component Achievement Medals, a National Defense Service Medal, and an Armed Forces Reserve Medal with an M device.
Deputy Acheson served with the Washington State Patrol from 2014 to 2022 as a trooper and firearms instructor in the Spokane area. He joined the Spokane County Sheriff’s Office on July 17, 2022, and was assigned to the Downtown Dayshift platoon. He was also a member of the Sheriff’s Office SWAT Team, serving as a sniper and providing overwatch during team operations.
He is survived by his wife and two children.

Law enforcement arrived at the Smythe Road home at around 2.25 pm and learned Larsen had an active felony warrant, according to Nowels. Deputies were concerned that he might have additional weapons and did not know whether more victims remained inside.
SWAT was called, and Perry, a K-9 deputy working with his dog Brego, joined the team approaching the house at around 3.15 pm. After deputies forced their way inside, gunfire erupted, striking Perry and Acheson before members of the team returned fire.
The wounded deputies were pulled to cover and given medical aid before Life Flight helicopters transported them to a hospital. The woman who had reported being shot in the chest was also taken to a hospital with injuries that appeared not to be life threatening.
A drone later entered the home and found Larsen dead, according to State Patrol. The Spokane County medical examiner determined Larsen died from a self inflicted gunshot wound, the Spokesman-Review Journal reported.
Two other people were killed, including Larsen’s mother, Suzanne Larsen, 72, and his sister Rebecca Larsen, 45, according to the outlet. His sister Julie Larsen, who called 911 after suffering a gunshot wound to the chest, survived.
The warrant stemmed from a 2015 incident in which Larsen allegedly pointed a gun at a dog walker on his property in Rosalia, according to records reviewed by the outlet. He was initially charged with second degree assault but was later convicted of aiming or discharging a firearm and spent ten days behind bars.
Larsen later appealed the conviction, which was dismissed in 2022, and had a failure to appear warrant connected to the case. Washington State Police said he had barricaded himself inside the home during Tuesday’s deadly confrontation.
Perry served with the sheriff’s office for nearly seven years and had served in the Washington Army National Guard since 2017. He reached the rank of Captain as a Military Intelligence Officer assigned to the 81st Brigade’s 1-161st Infantry Battalion and received two Army Commendation Medals and an Armed Forces Service Medal.
The sheriff’s office said Perry responded to the incident on his own and without prompting, reflecting how he consistently placed the safety of others before himself. His decision to donate his organs continued that service by helping people in need across the region and country.
Acheson joined the sheriff’s office in 2022 as a firearms instructor and was a trained sniper and sergeant with the Washington Army National Guard’s 3rd Battalion, 161st Infantry Regiment. The sheriff’s office said he dedicated his life to serving and protecting others.
Major General Gent Welsh of the Washington National Guard said messages about losses like these were among the hardest he had to share. He said the deputies represented the best of public service through their courage, commitment to others, and willingness to help their communities.
