Summary based on the NamUs case record (MP17624) and 4 other sources
Mark Julian Oldbury Jr., 31, was last seen on February 2, 2012, in Vidor, Texas. His uncle had dropped him off at Mansfield Ferry Road around 4:00 p.m. for what was supposed to be a solo fishing and camping trip. Mark was known to have a history of drug use, including bath salts, which can cause severe delusions and hallucinations. He had been dealing with mental health issues and was hospitalized for a mental evaluation just days before his disappearance. Despite his mother's objections, he was released from the hospital into his uncle's care on January 31, 2012, just a few days before going missing.

Search efforts revealed his belongings, including his clothes, shoes, fishing pole, wallet, and backpack, scattered across a wide area near where he was last seen, but no trace of Mark himself has been found. His family and investigators suspect that he may have drowned during his trip, though his body has never been recovered. In 2013, a year after his disappearance, his family held a memorial service after obtaining a death certificate.

Investigators continue to classify the case as lost or injured, but the exact circumstances of Mark's fate remain unclear. His case remains unsolved.
