SPOKANE, Wash. — Soon, you’ll notice many law enforcement patrol vehicles around Spokane County displaying memorial stickers honoring Sergeant Kenneth Salas, who died in the line of duty last month while helping motorists on Interstate 90. The “L558” stickers serve as a lasting tribute to Salas, a 34-year law enforcement veteran who was struck and killed by a motorcycle while clearing debris from the highway near Four Lakes. Salas began his career in law enforcement as a corrections officer before joining the Spokane County Sheriff’s Office. Throughout his three-decade career, he served as a patrol sergeant and held various roles, including school resource deputy and the traffic unit. The Cheney Police Department shared the significance of the memorial on social media Sunday, posting a photo of the new sticker on a patrol car.
