Man Sentenced To 20 Years In Prison For 2023 Beaverton Homicide (Photo) - 03/12/26

On February 23, 2023, Beaverton Police officers responded to a welfare check at an apartment complex located in the 1000 block of SW 160th Avenue.

Officers were dispatched to the location after receiving a report of a subject yelling for help from inside an apartment. When officers arrived, they contacted then 19-year-old Talon Gabriel Mitchell of Beaverton. Inside the apartment, officers discovered Mitchell’s wife, 24-year-old Oulaykham Mona Chopheng, deceased with an apparent gunshot wound to the head. Mitchell was detained at the scene, and detectives with the Beaverton Police Department’s Criminal Investigations Division (CID) were called to investigate.

During the investigation, detectives collected evidence which supported that Mitchell had shot and killed Chopheng earlier that evening. Mitchell was later indicted by a Washington County Grand Jury on charges of Murder in the Second Degree and Unlawful Use of a Weapon.

On March 10, 2026, Mitchell pleaded guilty to Manslaughter in the First Degree (with a firearm) and was sentenced to 240 months (20 years) in prison, with no post-prison supervision. He also pleaded guilty to Unlawful Use of a Weapon and received a 16-month sentence, which will run concurrently with the primary sentence.

The Beaverton Police Department recognizes the extensive work of patrol officers, detectives and prosecutors at the Washington County District Attorney’s Office. The coordinated effort was instrumental in bringing justice to Chopheng and her family
