Justin Weldon O’Brien, 23, was last seen April 29, 2002, in Waco, Texas. He told family he was going to his mother’s birthday party but never arrived. His apartment was found unusually clean, and two days later his truck was left abandoned near a bus stop in Dallas, about 100 miles from Waco.

Investigators suspect foul play and have linked his disappearance to possible involvement in methamphetamine dealings with the Aryan Circle, a violent white supremacist gang. Authorities believe O’Brien was likely murdered and have identified a primary suspect, but his body has never been found and the case remains unsolved. Both of his parents have died since he went missing; his sister continues to seek answers.

If anyone knew Justin, saw his truck in late April 2002, or has information about his activities or associates at that time, please come forward.
