Details of Disappearance
Engebretson became separated from his father and grandfather while they were looking for a Christmas tree in the Rocky Point area of the Winema National Forest in Klamath County, Oregon on December 5, 1998. Extensive air and ground searches yielded few clues as to Engebretson's whereabouts. A blizzard hit the area the evening Derrick was reported missing which destroyed any tracks that may have been left.
Volunteer searchers discovered a candy wrapper and a Bonanza School bookmark near Rocky Point several days after Engebretson disappeared. Blood of an unknown origin was also located at the scene. It is not known if the materials were connected to Engebretson's case.
An unidentified adult male was driving a black Honda in the Rocky Point area on December 5. The individual reportedly asked for directions while in the forest. A witness allegedly saw an unidentified individual struggling with a young boy near the area later in the day. Investigators do not know if the incident is related to Engebretson's case.
In November 2002 Investigators announced that they identified a 'person of interst' in Engebretson's case however the suspect was not named.
