In August of 2023, a 37-year-old woman headed out for a beautiful summer hike two hours before sunset. When darkness fell upon the day and she hadn’t returned home, her boyfriend discovered her car still at the trailhead late in the night, prompting him to call police and report her missing. When her body was found the following day, she and the scene were processed, quickly leading investigators to link foreign DNA on her body to another crime that was committed across the country. This is the story of Rachel Morin.
