Cold Case Files

Near what's known as the hanging tree, the mutilated body of Timothy Coggins is found in late 1983. The investigation is thwarted and the case freezes for over 30 years, until a newly elected sheriff vows to bring the killers to justice.

On a bitter morning in 1980, radio intern Helene Pruszynski is found brutalized in a snowy field. After 37 years of fruitless leads, investigators tap into a public genealogy website that leads them across the country to the killer they've been hunting.

Easter Sunday of 1992, the body of missing woman Lisa Ziegert is found in a field. The investigation yields hundreds of leads but no true suspect. After more than two decades on ice, the case is revived when DNA phenotyping puts a face to the killer.

Just after the last day of school in 1984, 15-year-old Reesa Trexler is found murdered in her grandparents' home. For decades, a stalled investigation only fuels the town rumor mill, pointing an accusing finger at Reesa's 13-year-old sister, Jodie.
