On a Saturday night in late June of 1986, a 20-year-old college student went out with friends in a familiar place, celebrating her softball team’s big win. But in a narrow window of opportunity just after she was dropped off in the shadows outside her apartment building, the young woman faced an evil that managed to stay hidden in those same shadows for decades.Investigators searched for connections…People who knew her, places she had been, anything that might explain her senseless death. But nothing fit. Leads faded. The case stalled. And over time, it slipped into that uncertain space between open and unsolved.For decades, the answer remained just out of reach until advances in science, and a single piece of preserved evidence, began to tell a different story.
