Details of Disappearance
Gaunt was last seen at her home in San Diego County, California sometime in early 1992. She lived on Anza Avenue just outside the Vista city limits.
At the time of her disappearance, she and her live-in boyfriend, Christopher McDonald, were in the middle of a custody battle over their two-year-old daughter. Gaunt has never been heard from again. By the summer of 1992, McDonald had a new girlfriend who moved into the residence he'd shared with Gaunt.
No one reported Gaunt missing; it wasn't until May 1993 that a witness told police she had been missing for over a year and may have been murdered. McDonald raised their daughter for only a short time before sending her to Massachusetts to be raised by his parents.
In August 2017, McDonald was arrested in Safford, Arizona, where he'd lived for years, and charged with Gaunt's murder. A photo of him is posted with this case summary.
Investigators believe he murdered her at their home in San Diego County on or around January 1, 1992 and disposed of her body in northern San Diego County or Riverside County. They described the case against McDonald as circumstantial. He is awaiting trial.
Foul play is suspected in Gaunt's case due to the circumstances involved.
