DOUGLAS COUNTY, Ore. – The Douglas County Sheriff’s Office continues to investigate the disappearance of a Christmas Valley man whose vehicle was previously located abandoned in the Elliott State Forest, and investigators are again asking for the public’s assistance.  Since the initial report, Douglas County Search and Rescue, along with teams from Josephine, Jackson, Siskiyou, and Klamath Counties have conducted supplemental searches in and around the area where the vehicle was found. Those efforts did not reveal any additional information or result in locating 61-year-old Robert Cotter.  The investigation remains ongoing, and deputies continue to follow up on leads and information related to Cotter’s disappearance. Cotter was last seen on November 2, 2025, and his white 2002 Ford utility pickup was discovered unoccupied on November 30, 2025, on an unmaintained roadway in the Elliott State Forest near Loon Lake.  The Sheriff’s Office is again asking anyone who may have seen Cotter, had contact with him, or observed his vehicle after November 2nd to come forward. Even information that may seem minor could be helpful to the investigation. Please call (541) 440-4471 and reference Douglas County Sheriff’s Office case #25-4113.  In addition to the agencies listed above, the Douglas County Sheriff’s Office has received investigative assistance from the Lake County Sheriff’s Office.
