84-year-old sentenced to life in prison for killing Minneapolis woman more than 50 years ago
- On Thursday, Jon Keith Miller, an 84-year-old man, was sentenced to life in prison for the 1974 murder of 25-year-old Mary K. Schlais of Minneapolis in Dunn County, Wisconsin.
- Mary Schlais was last seen in uptown Minneapolis hitchhiking to an art show in Chicago when Miller picked her up, later stabbing her to death after she refused his sexual advances and dumping her body in a ditch covered with snow.
- The case remained unsolved for nearly 50 years until advancements in DNA technology and genetic genealogy, along with the help of Miller's biological relatives, led investigators to identify him as the suspect through a winter stocking hat left near the victim's body.
- Miller confessed to stabbing Schlais, telling KARE 11 reporter Lou Raguse that he wanted to have sex with her, and admitted the stocking cap found at the scene was his, though he initially believed he had "gotten away with it" because a witness misremembered the color of his car.
- Miller's sentencing, which he did not address the family during, brings closure to the decades-long investigation and allows Mary Schlais' family to focus on remembering her as a person, as expressed by Nina Schlais who thanked the Dunn County Sheriff's Office and the team at Ramapo College for their dedication.
