New potential evidence
What we know:
The Fond du Lac County Sheriff's Office said a search of that Campbellsport home was completed on Tuesday, and the home was released back to the current property owner, who has no connection to the Fritz family or the case.
The excavation was the result of a July 16 search warrant served at the home, which the sheriff's office said uncovered potential evidence related to the case.
Investigators excavated the basement entirely with hand tools, removed and processed approximately 30,000 pounds of soil. That dirt was hand-sifted and searched, and items of interest were collected as potential evidence.
While investigators did not find Fritz's remains, they did find potential evidence that will be subject to further analysis. It could take several months or longer to analyze what was collected.
