Dorien Deon Thomas was 9 years old when he vanished from his Amarillo, Texas, neighborhood on October 26, 1998. He was last seen riding an aqua blue bicycle with white tires near Northwest Ninth Avenue; he had just filled the tires with air and was reportedly heading to meet a friend. He was wearing a red shirt and blue jeans. Neither Dorien nor his bicycle has ever been found.

Dorien’s family did not report him missing until more than 24 hours after he was last seen. Authorities have called the circumstances unclear and suspect foul play. A year earlier Dorien and friends had discovered a woman’s body in a park, a separate unsolved homicide that has been mentioned as potentially linked to his disappearance. Despite extensive searches and investigations, no significant leads have been announced and the case remains open.

If anyone remembers seeing a boy on an aqua blue bike near Northwest Ninth Avenue in late October 1998 or has information about Dorien, please come forward.
