The remains were uncovered about 40 minutes into the cleanup.

"We thought the worst thing we'd find was a condom that we saw," Jennifer Dacus, the mother of one of the boys, told the Erie Times-News. "This was worse."

Erie police are investigating and the Erie County Coroner’s Office will determine if the skull is human.
