Casper Wyoming is a quiet town. But in 1973, it was marred by an horrific crime. Two girls, sisters - Becky Thompson and Amy Burridge - were snatched off the street, attacked and driven 35 miles to an iron bridge over Fremont Canyon. Then the two men that took them threw them over. But one of the girls survived the 112 foot fall and identified Ronald Kennedy and Jerry Jenkins as the men who attacked them. Still, tragedy would follow her.
