Fond du Lac County Sheriff’s Office excavating at undisclosed locations in cold case

The Fond du Lac County Sheriff’s Office remains steadfast in its commitment to investigating unsolved crimes and cold cases, including an investigation into the disappearance of Robert “Bobby Jo” Fritz on May 14, 1983.

Earlier this year, detectives recovered items of interest and potential evidence during an excavation at the Campbellsport residence where Bobby Jo lived at the time of his disappearance. Those items have been sent to a private laboratory for testing, and results are pending.

Detectives are now excavating at additional locations in southeast Fond du Lac County. These sites have been identified as areas of interest that may contain evidence related to Bobby Jo’s disappearance.

Investigators will continue to pursue every credible lead and follow up on all new
information received.

The Fond du Lac County Sheriff’s Office is dedicated to uncovering the facts surrounding Bobby Jo’s disappearance and bringing closure to his family. As this remains an active and ongoing
investigation, additional information will only be released at a time when it will not compromise case integrity.
