This is part 2 in the series, "Joli Truelson: Connecting the Dots," which examines the devastating impact of a flawed investigation by the Minneapolis Police Department into the 1972 slaying of 16-year-old Joli Truelson – and her family’s renewed fight for answers in the wake of a killer’s confession.

Joli Truelson was picked up on the evening of July 3, 1972 in Uptown Minneapolis by a man driving a newer model, gold-colored, two-door vehicle. Her body was discovered 15 hours later in Minnehaha Creek, four miles away. She died from blunt force trauma to the back of her head, insinuating that she was running away from her attacker. Critical evidence was thrown away, including the possible murder weapon. Since then, her case has gone cold.

Joli Truelson’s brother, though, always thought her death could be linked to a similar crime: the death of 25-year-old Mary Schlais in 1974.

On Nov. 7, 2024, Jon K Miller, 84, confessed to picking up Mary Schlais while she was hitchhiking in Minneapolis. When she refused to have sex with him, he stabbed her 15 times. He drove to Dunn County, Wisconsin – roughly 90 miles away – and dumped her body in a ditch.

An eyewitness saw it all – and called it in to authorities. He described the man as being in his mid-30s with mid-length brown hair. He described the vehicle as a newer model, gold-colored, two-door car. The killer went more than 50 years without being caught, until advancements in DNA led authorities to Jon K Miller's rural Minnesota assisted living facility door. When confronted with evidence, he confessed.

With the help of Joli Truelson’s family, this series digs deep into the life and criminal history of Jon K Miller, attempting to answer the question: Did he murder Joli Truelson?

Jon K Miller has been questioned in Joli Truelson’s murder investigation, but has not been charged with any crimes related to her death.
