Horgan was last seen in Albuquerque, New Mexico on April 29, 1997. She had been hired for a job at the Budget 8 Motel but never showed up for work. On June 21, almost two months later, her white 1976 Ford Thunderbird was found in the west side of Albuquerque on Fortuna Road and West Coors Boulevard, abandoned and vandalized; it looked like it had been in an accident.

Clothing, bags, tennis shoes, and broken glass was scattered all over the back seat and floorboards of the Thunderbird.

Horgan has never been heard from again. Her mother claims that, two weeks prior to her disappearance, Horgan's boyfriend raped and beat her badly enough to put her in the hospital. No charges were filed in the incident and it's unclear whether it's related to her later disappearance.

Horgan has lived in Memphis, Tennessee and Jackson and Tupelo, Mississippi. She has previously worked as a cook and waitress for schools and restaurants. She left behind two children when she went missing, as well as a husband; her husband died in September of 1997. Horgan's case remains unsolved. Foul play is suspected
