David Allen Crabtree was 13 when he disappeared from his home in Locust Grove, Oklahoma, on the evening of April 9, 2000. Family members say he told his siblings he was going to bed and said he loved them, then is believed to have crawled out of his bedroom window between 7:00 and 8:00 p.m. to meet three boys waiting outside. His sister recalled seeing those boys and said they had asked her to join them; she declined. David was last seen in a grey shirt and black pants.

In the days before he vanished David had run away once and had been found intoxicated on April 5; his parents briefly placed him in a juvenile center. Law enforcement initially classified him as a runaway; the case was reclassified as a missing person in 2017. Unconfirmed sightings were reported in Pryor, Tahlequah, and Kenwood. He is described as a Native American male, 5 feet 5 inches, 125 pounds, dark brown hair, brown eyes, with a scar on his eyebrow (reported as the right) and a scar at the top center of his head; he may have had a mustache.

No public statement is available about whether investigators believe he is alive or deceased. If anyone knew David, the three boys seen that night, or has information about his movements after April 9, 2000, please come forward.
