Joliet investigators were back on the scene Sunday in search for human remains after a skull was found in unincorporated Will County.
Surveyors discovered the human skull in a creek under a bridge on Rowell Avenue on Thursday.
Sheriff’s police had cadaver dogs searching for other remains on Friday, but no more were found.
A forensic anthropologist will have to figure out the age and gender because the teeth are missing.
Investigators think the skull was in the creek for a while and was exposed when the water level dropped.
They say there is illegal dumping in the area and that the skull could have come from a medical school nearby.
