Justin Weldon O’Brien was 23 when he vanished from his Sanger Avenue apartment in Waco, Texas. He was last seen on April 29, 2002, after saying he was on his way to his mother’s birthday party; he never arrived and has not been heard from since.

Two days later his burgundy pickup truck was found abandoned and in immaculate condition near a bus stop in Dallas, about 100 miles north of Waco. His apartment had been thoroughly cleaned. Investigators suspect foul play and believe he was murdered. Authorities say his disappearance is linked to alleged sales of methamphetamine to the Aryan Circle, and that multiple people were involved; a primary person of interest has been identified. Both of O’Brien’s parents have since died and his sister continues to seek answers.

If anyone knew Justin, his movements in late April 2002, or the location of his truck after April 29, please share what was seen or known.
