Christina Jeanette Chandler, 29, vanished from Fort Worth, Texas on September 30, 1990. She was last seen getting into a pickup truck with several unidentified men, according to her then-boyfriend. Her own vehicle turned up later in Lubbock with a broken rear window and traces of blood inside, and investigators have listed her as an endangered missing person.

Christina was described as someone who associated with motorcyclists and had a history of drug use, but her family says it would have been highly unusual for her to leave with people she didn’t know. She had several distinctive tattoos—a unicorn on her back, a rose on her abdomen, and a peacock on her chest—plus a scar on her right leg and skin discoloration on her right ear. Investigators have not ruled out foul play, and no confirmed trace of Christina has surfaced since her disappearance.

If anyone knew Christina, saw her vehicle after September 30, 1990, or has information about the pickup truck or the men she was seen with, please come forward.
