Summary based on the NamUs case record (MP26191) and 4 other sources
Tiffany Felky Doyle, a 26-year-old woman, was last seen in Santa Cruz, California, on November 8, 1974. It is believed that she may have been hitchhiking on the day of her disappearance. Despite initial reports of her missing status being filed by her sister, the original case file was purged, and Tiffany was effectively forgotten for decades. It wasn't until 2014, nearly 40 years later, that her case was reported missing again.

On the day she vanished, Tiffany was described as wearing a brown nylon jacket and a multicolored stocking cap, and she was carrying a green day pack. At the time of her disappearance, she had an unspecified medical condition that required medication, which she did not have with her. Her case remains classified as endangered missing, and little information is available about the circumstances surrounding her disappearance.

The lack of leads and the long passage of time have made it challenging to uncover new details. Investigators continue to seek information regarding Tiffany's case, hoping that renewed attention might yield new insights. If anyone has information that could assist in the investigation, they are encouraged to contact the Santa Cruz Sheriff's Department.
