Who Murdered Mary Schlais? The 1974 Wisconsin Cold Case Breakthrough
On a cold February morning in 1974, a 25-year-old artist left her Minneapolis apartment to hitchhike to a Chicago art show and was found dead in a Wisconsin snowbank 90 miles east. Near her body, investigators found a stocking cap that didn't belong to her. For 50 years, that hat sat in an evidence room, tested and retested as technology improved, never producing a name. When genetic genealogy finally traced the killer through an adoption wall and across three states, investigators knocked on the door of an 84-year-old man. He opened it and told them he already knew why they were there. Make sure you subscribe to get your regular crime: fix. / @911crimewatch #truecrime #coldcase #crime #crimewatch #maryschlais
