Deseret News Share this story Family photo Spools of magnetic tape captured the voice of Joyce Yost on the morning of April 4, 1985. An audio cassette rolled as Yost offered a step-by-step account of her sexual assault at the hands of a man she’d never met. “He grabbed me by the throat and he was forceful and told me if I screamed or said anything that he would tear my throat open,” Yost can be heard saying through the tape’s analog hiss. Joyce Yost’s police report Yost had spent the evening prior to her report having dinner with a friend at a supper club called Pier 3. She’d parted ways with that friend in the parking lot outside of the club a bit after 10 p.m.
