Mark Delmar Engelhart was 47 when he disappeared from Hermiston, Oregon in late July 2003. A landscaper who cared for animals on his ranch, Engelhart missed tending his animals, failed to show up for a scheduled job, and did not attend his parents’ 47th wedding anniversary on July 24. His family reported him missing on July 26 after finding his pickup truck and personal belongings gone.

Investigators focused on Engelhart’s roommate and friend, Jonathan Theodore Flaiz, who also vanished around that time and was later found in Washington appearing stressed and giving inconsistent accounts. Engelhart’s truck was located on August 16 at a hotel in Gresham with a large amount of blood on the tailgate. Flaiz told authorities he had struck Engelhart while he slept and later buried him in a wooded area within about an hour’s drive of Hermiston; searches based on his statements have not recovered a body.

Engelhart’s family continues to seek answers and a way to bring him home. If anyone has information about Mark Engelhart’s movements in late July 2003 or the location described for his burial, please come forward.
