Joyce Yost was 39 when she disappeared from South Ogden, Utah, on August 10, 1985. Her disappearance followed a prior attack in April 1985; she had testified against Douglas Lovell for that kidnapping and sexual assault and was preparing to testify at his trial.

Yost’s car was found abandoned in the foothills east of Ogden soon after she went missing. Her body has never been recovered despite weeks of searching.

Lovell eventually confessed to the killing and was convicted; the family continues to seek closure because her remains remain missing. Does anyone have information about Joyce’s movements in Ogden in August 1985 or about the foothills area where her car was located?
