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

An investigation at the time revealed that Schlais had hitchhiked from Minneapolis to Chicago for an art exhibition.

Dunn County Sheriff’s Office law enforcement officials said they have received numerous tips and leads in the decades since Schlais’ body was found. As DNA technology improved, authorities retested evidence found at the scene many times.

Genetic genealogy testing in collaboration with Ramapo College in Mahwah, New Jersey, revealed a suspect, which led to Miller’s arrest on Thursday.

Miller is currently in custody and awaiting extradition to Wisconsin.
