A major development has been made in a 43-year-old missing child cold case in Fond du Lac County.
On May 14th, 1983, 6-year-old Robert “Bobby Jo” Fritz went missing while playing in front of his home in the Village of Campbellsport.
Last week, the Fond du Lac County Sheriff’s Office executed a search warrant at the home where Bobby Jo lived at the time of his disappearance.
During that search, potential evidence linked to his disappearance was found.
As a result of those findings, a large-scale excavation is underway in the basement of the home.
At this time, detectives are working alongside members of the Wisconsin Department of Justice Division of Criminal Investigation and Crime Lab to obtain, collect, and process any additional evidence.
Along with the announcement, the Sheriff’s Office added, “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.”
