Investigators say they found possible evidence in the decades-old disappearance of Robert “Bobby Joe” Fritz and are now digging in the basement of the Campbellsport home where he lived when he vanished.

The Fond du Lac County Sheriff’s Office said detectives served a search warrant Thursday, July 16, at the house where Bobby Joe lived when he disappeared.

During that search, investigators located what they described as potential evidence.

Because of that, the sheriff’s office said a larger excavation is now underway inside the home’s basement with help from the Wisconsin Department of Justice Division of Criminal Investigation and the state Crime Lab.

Robert was last seen playing in an empty lot in his family's Campbellsport, Wisconsin neighborhood on May 14, 1983. The lot was beside the Mill Pond/Milwaukee River in the area where the Campbellsport Firehouse now stands. He was with his sister and friends approximately one-half block from the family's residence when he was last seen.

Sometime between 2:30 and 4:30 p.m., Robert told his sister he was hungry and was going to walk home. Robert never arrived home and has never been heard from again. The toy gun he'd been playing with was later found. After Robert's disappearance, an extensive search was made of the Milwaukee River and the Mill Pond, on the theory that he had drowned. No trace of him was ever found.
