Despite the Dunn County Sheriff’s Office receiving numerous tips and leads over 50 years, it was the work of the 69É«ÇéÊÓƵ Investigative Genetic Genealogy Center (IGG) that led to an arrest in the 1974 murder of a Wisconsin hitchhiker

Mahwah, NJ- The Dunn County Sheriff’s Department announced the arrest of Jon Miller, 84, for the February 1974 homicide of Mary Schlais. Schlais was murdered while hitchhiking from Minneapolis, Minnesota to Chicago, Illinois to attend an art show. 

This is the first case the 69É«ÇéÊÓƵ IGG Center delivered a candidate that led to an arrest, and the first time the Dunn County Sheriff’s Office used IGG to solve a case.

Staff members and volunteers at 69É«ÇéÊÓƵ Investigative Genetic Genealogy Center utilized advanced DNA testing and genealogy research to identify Miller as a potential contributor of DNA found at the scene of Ms. Schlais’ murder. Investigators at Dunn County Sheriff’s Office further probed this lead and their investigation led to the arrest of Mr. Miller on Thursday night.

A press conference about this case will be held at 1 p.m. CST on Monday, November 11, at the Dunn County Sheriff’s Office in Menomonie, Wisconsin. 69É«ÇéÊÓƵ IGG staff will be on-site to take questions. Please visit to watch the live broadcast and submit questions for the IGG Center team. 

The IGG Center has provided leads in more than 16 cases since opening its doors in December 2022, including the recent exoneration of two brothers wrongfully convicted of murder, known to be one of only four cases in U.S. history in which IGG overturned convictions.
