Authorities have released the names of the Spokane County sheriff's deputies who died in a shooting south of Spokane, as well as that of the man who is suspected of killing them.
The county medical examiner's office also released the names of two other victims of Tuesday's shootout in the tiny community of Spangle.
The sheriff's office Friday identified the two deputies as Parker Perry and Mason Acheson. Acheson died early Wednesday at Providence Sacred Heart Medical Center in Spokane. Perry, an organ donor, died later after being on life support, according to the office's social media post.
The suspect was identified by the medical examiner's office as 37-year old Ryan Larsen. The office said he died from a gunshot wound to the head.
Two of the victims were identified as Suzanne Larsen, 72, and 45-year-old Rebecca Larsen. Both had been shot in the head, the medical examiner reported.
Parker and Acheson were part of a SWAT response to the Larsen home at 18819 S. Smythe Road on Tuesday afternoon to reports of a woman claiming she had been shot in the chest by her brother, according to the sheriff's news release.
During their investigation, deputies learned the suspect had an active warrant for his arrest and likely had access to other weapons.
While approaching the home, the team was met with gunfire, and both deputies were struck. Other deputies returned fire, killing the suspect.
The deaths of two deputies mark the worst day for a Washington police agency since the 2009 assassinations of four Lakewood officers.
Two people, including the suspect, were found dead inside the house. Another was found dead outside.
In addition, a woman suffered a non-life-threatening gunshot wound.
Acheson was a four-year veteran of the sheriff's office who came from the Washington State Patrol, where he was a trooper from 2014 through 2022. He was also a gun instructor at the State Patrol, according to a release from the sheriff's office.
The sheriff's office said Acheson served with the Washington State Army National Guard, where he achieved the rank of sergeant. He served with the guard in Poland for a year beginning in 2021.
He was a trained sniper and served in that capacity with the sheriff's office
SWAT team, according to the release.
The sheriff's office said he is survived by his wife and two children.
Perry, a K-9 officer, died from wounds suffered in the shootout.
He joined the sheriff's office in 2020 after earning a degree in business administration from Carroll College in Montana.
Perry also served in the Washington Army National Guard, where he achieved the rank of captain as a military intelligence officer. He was awarded two Army Commendation medals and an Armed Forces Service Medal.
Perry was a member of the Spokane County sheriff's SWAT team from 2022 until being selected as a K-9 deputy in 2025.
Knowing that there was another victim’s life in jeopardy, he joined his teammates and moved toward the house. During this attempted rescue, he bravely forced entry, knowing that there was danger inside to protect another, the sheriff's office said.
Perry is survived by his pregnant wife and two children, the sheriff's office said.
