Shelia Sue Conner, 30, vanished from North Houston on December 31, 1991. She was last seen at the home of an older man she’d been in a relationship with; about 3:30 a.m. that morning she called a friend to say she’d had an argument with him and was never heard from again. Her car was later found abandoned and stripped on Interstate 45 North near New Haven, Texas.

Shelia had several tattoos and a scar on her chin; she was wearing a black jacket and blue jeans when last seen. Her eight-year-old son has long believed she may have been murdered, and the condition and location of the vehicle have been treated by investigators as suspicious. No definitive evidence has been publicly identified and the case remains unsolved.

Anyone with memories of North Houston on that night, knowledge about the man she was with, or information about the abandoned vehicle is asked to come forward.
