William Arlin Bynum, known as Arlin, was 40 when he vanished from Big Spring, Texas, on August 15, 2003. He was last seen at about 2:00 a.m. at the San Franciscan Bar and Grill at Third Street and Runnels Street. Witnesses say he left the bar after closing his tab with an unidentified man and never returned home; his truck was later found in the bar parking lot.

Bynum’s routine activity that day was out of character: he missed a lunch meeting with his brother-in-law and made no further phone calls. There has been no activity on his cellphone or credit cards and no withdrawals from his bank account since his disappearance. Police found no evidence of foul play or blood at his home, though authorities and the family consider foul play possible and list him as endangered missing. A 2008 tip led to a search of a farmhouse north of Big Spring but turned up nothing. His family believes he is no longer alive.

Does anyone who knew Arlin, his bar, or the local motorcycle community have information that could help clarify what happened that night?
