An Owatonna man is in custody after genetic genealogy linked him to the 1974 murder of a Minneapolis woman who was found in Dunn County.

Jon Miller, 84, was arrested Thursday for the murder of Mary Schlais, who was found dead in Spring Brook Township on Feb. 16, 1974.

At that time, an investigation revealed that Schlais was hitchhiking from Minneapolis to Chicago for an art exhibition.

Dunn County police say they have received numerous tips and leads in the decades since Schlais’ body was discovered. As DNA technology advanced, officials retested evidence found at the scene several times.

In collaboration with Ramapo College in Mahwah, New Jersey, genetic genealogy testing revealed a suspect, leading to Miller’s arrest Thursday.

Miller is currently in custody and awaiting extradition to Wisconsin.
