"Decker has a history of hitch hiking – we would like to encourage the public to not pick up any hitchhikers. Additionally, any drone flights in the area will inhibit our ability to search with aircraft – please do not fly any drones for the safety of aircrews." - Michael Leigh, Supervisory Deputy - U.S. Marshals Service
Over the last few days, the U.S. Marshals Service Greater Idaho Fugitive Task Force, U.S. Forest Service, and Camas County Sheriff’s Office have been searching areas "believed to be accessible to a person in Decker’s condition."
Authorities are also urging the public to avoid flying drones in the area, as such action can hinder their ability to search for the suspect from the air.
