Tiffany Felky Doyle, 26, was last seen in Santa Cruz, California, on November 8, 1974. She was reportedly wearing a brown nylon jacket, a multicolored stocking cap, and carrying a green day pack. It is believed she may have been hitchhiking that day and she had a medical condition requiring medication that she did not have with her.

An initial missing-person report was filed by her sister, but the original case file was purged and Tiffany’s disappearance went unrecognized for decades. Her case was reported again in 2014 and is currently classified as endangered missing. There are very few leads and limited information about the circumstances of her disappearance.

Did anyone in the Santa Cruz area in November 1974 see Tiffany, her green day pack, or a vehicle that picked up a young woman matching her description?
