Deputies Served in Military and Law Enforcement
Acheson joined the Spokane County Sheriff’s Office on July 17, 2022. He also spent eight years with the Washington State Patrol, where he served as a firearms instructor in the Spokane area.
He also served in the Washington Army National Guard, earning the rank of sergeant. His military service included a deployment to Poland in 2021-22, sniper training and multiple military commendations.
Perry joined the sheriff’s office in May 2020 after earning a bachelor’s degree in business administration from Carroll College in Montana.
He also served in the Washington Army National Guard, reaching the rank of captain as a military intelligence officer with the 81st Brigade’s 1-161st Infantry Battalion.
Perry served on the sheriff’s office SWAT team from 2022 until his selection as a K-9 deputy in 2025. He and his K-9 partner, Brego, responded to the Nov. 3 shooting.
According to the sheriff’s office, Perry immediately responded to the call and moved toward the residence after learning another person’s life remained in danger. He forced entry despite the threat inside in an attempt to rescue the person.
Perry later died from his injuries. He and his family chose organ donation, allowing his organs to help people in need across the region and country.
Acheson and Perry both leave behind two grieving families and colleagues across Washington who are remembering their service.
