In 1982 a young, good-looking construction worker, went to a bar with a friend. It was Valentine's Day and maybe that's what led to some flirtatious interactions with a woman that took a  deadly turn. Almost 40 years on, the murder has not been solved and little information has emerged. We talk to Pam Genovesi, a prominent PI in the 1980s, who investigated the Trent Olsen murder and has information that hasn't been pubicly disclosed before.
