December 12, 1985. St. Croix Falls, Wisconsin. A quiet morning was shattered by gunfire. Forty-five-year-old mother of four, Yvonne Menke, was found shot to death outside her apartment—one bullet to the neck, two to the back of the head. The killer vanished, leaving behind only footprints in the snow and a trail of unanswered questions.

For decades, the case went cold. No arrests. No justice. But in 2021, a renewed investigation unearthed chilling forensic evidence: boot prints matching a rare pair of snow boots, and a note with a suspect’s car information found in Yvonne’s purse. 

This is the story of obsession, betrayal, and a murder that remained frozen in time for nearly 40 years until forensic clues finally brought a killer to justice.
