SPOKANE, Wash. — Spokane County Sheriff’s Office has released the names of the two deputies killed this week in a shooting.
According to the sheriff’s office, Deputy Mason Acheson and Deputy Parker Perry headed to a home near Spangle Tuesday afternoon after a woman showed up at a neighbor’s house with a gunshot wound.
Investigators said the shooter shot and killed two other people before barricading himself inside and opening fire on deputies when they got there.

Deputy Acheson was commissioned with the Sheriff’s Office in July of 2022 after working with the Washington State Patrol for eight years as a Trooper and Firearms instructor.
He enlisted in the Washington Army National Guard in 2011 and served in Poland in 2021-2022, where he competed in Army sniper competitions, 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.

He served alongside Acheson on the county’s SWAT team starting in 2022 until he began serving with his K9 companion, Brego, who responded with him to the shooting in Spangle.
