Second deputy dies following Spangle shooting in Spokane County

The Spokane County Sheriff’s Office announced Monday on Facebook that Spokane County Sheriff’s Deputy Parker Perry had officially passed away. Deputy Perry succumbed to his injuries on Nov. 6, after responding to a domestic violence shooting in Spangle on Nov. 3.

Deputy Parker is survived by his wife, two children, and one child on the way. Perry was the second sheriff’s deputy for Spokane County to die while responding to the initial incident. Authorities noted shortly after the incident that Perry was not expected to survive and was on life support.

“Deputy Parker Perry passes after a heroic battle and continues in death to give to his community and country. It is with great sadness that the Spokane County Sheriff’s Office announces the passing of Deputy K-9/Washington National Guard Captain Parker Perry,” authorities wrote on Facebook. “He succumbed to his injuries on November 6, 2026, surrounded by his family, friends, fellow military members, and co-workers.”

Due to being an organ donor, Deputy Perry’s remains have been donated to those in need across the country.

Three people were reportedly killed in the original incident, including the suspect and two victims.

Deputy Parker Perry background

Perry was commissioned to work with the sheriff’s office in 2020. Before that, he earned his bachelor’s degree in business administration from Carroll College in Montana.

Perry served in the Washington Army National Guard since 2017, earning the rank of captain as a military intelligence officer assigned to the 81st Brigade’s 1-161st Infantry Battalion, where he was awarded two Army Commendation Medals and an Armed Forces Service Medal.

He then served on the sheriff’s office SWAT team from 2022 until he was selected as a K9 Deputy in 2025. He and his K9, Brego, responded to the domestic violence shooting call on Tuesday.

“He immediately responded on his own, without prompting, an example of how he lived life, always prioritizing the safety of others before his own,” the sheriff’s office wrote. “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.

“Deputy Perry laid down his life to rescue another during this entry and was critically injured in the process,” officials continued. “Though gravely injured, Deputy Parker Perry and his family chose to continue his selfless service to others by donating his organs to ensure others in need across this region and country will live.”

Deputy Mason Acheson served as SWAT sniper and National Guard sergeant

Deputy Mason Acheson died one day after the incident in the hospital. He is survived by his wife and two children.

Acheson was commissioned to work with the sheriff’s office in 2022. Before that, he worked with the Washington State Patrol as a trooper and firearms instructor. He enlisted in the Washington Army National Guard in 2011 and served in Poland from 2021 to 2022.

He earned three Army Commendation Medals, one Army Achievement Medal, three Army Reserve Component Achievement Medals, a National Defense Service Medal, and an Armed Forces Reserve Medal with an M (mobilization) device.

“Deputy Acheson was commissioned and served with distinction within the Spokane County Sheriff’s Office and was assigned to the Spokane County Sheriff’s Office Downtown Dayshift platoon,” the sheriff’s office wrote. “He proudly served on the Spokane County Sheriff’s Office SWAT Team.”

Acheson was a SWAT sniper, where he provided overwatch for team members.

“Deputy Acheson made the ultimate sacrifice for his country, community, and fellow team members,” SCSO stated. “In the face of danger, he stepped forward to preserve life, and in this selfless act of bravery, he lost his life while trying to protect others. He dedicated himself to serving others in both the military and law enforcement, leaving a lasting impact through his selfless commitment to service.”

The previous details

A domestic violence shooting originally killed three people and critically injured two Spokane County Sheriff’s Office (SCSO) deputies Tuesday afternoon, KHQ reported.

At approximately 2:25 p.m., SCSO deputies responded to reports of the shooting at a residence in the 18700 block of S. Smythe Road in South Spokane County, SCSO announced.

Initially, one adult female victim said she was shot and required medical attention. She was transported to a hospital for non-life-threatening injuries. The suspect reportedly was the brother of the woman, according to The Spokesman-Review.

As deputies arrived on scene, they learned that the adult male suspect had an active felony warrant for his arrest, could have access to other weapons, and there may be additional victims.

After the Spokane County SWAT Team responded to assist, both deputies and SWAT approached the suspect’s residence and made entry as officials feared for the victim’s safety.

Washington State Patrol told KIRO Newsradio the agency is investigating the officer-involved shooting.
