In 1981, a 23-year-old woman was dragged kicking and screaming from her East Lansing apartment in front of an entire building full of onlookers. In 1982, a rebellious teen vanished while hitchhiking in a Detroit suburb. In 1983, almost exactly one year later, another pretty brunette teenager disappeared while hitchhiking in the same neighborhood. Three years, three murdered women, three cold cases. One would become the first case in Ingham County to use DNA as evidence. One would be solved through new advancements in DNA technology decades later. And one would be solved by a team of eagle-eyed students at Michigan State University's School of Criminal Justice. But for decades, their grieving families waited for invisible strings to connect and lead to justice.
