Wilcox was last seen riding in a yellow Volkswagen Bug in Holladay, Utah on October 2, 1974. She has never been heard from again. She was a high school student and a cheerleader when she vanished. Authorities initially classified her as a runaway, but she was only the first of many girls and young women to disappear from Utah during this time period.

Wilcox is believed to have been a victim of the serial killer Ted Bundy. A photograph of Bundy is posted below this case summary. He was executed in Florida in 1989 and confessed to many murders before his death, including Wilcox's. She fits the profile of his other victims and he was known to have been in the area at the time of her disappearance, and he drove a Volkswagen Bug similar to car she was seen riding in. Bundy stated she was never in his car, however. He confessed that he abducted her at knifepoint, sexually assaulted her in a nearby orchard, and strangled her. He said he buried her body near Capitol Reef National Park. It has never been found.

Bundy is also thought to be responsible for the murders of Nancy Baird, Ann Marie Burr, Lynette Culver, Julie Cunningham, Susan Curtis, Georgeann Hawkins, Vicki Hollar, Rita Jolly, Debra Kent, Donna Manson, Denise Oliverson and many other young women. The women continue to be listed as missing persons. Their remains have never been recovered.
