Multiple agencies are investigating the discovery of a human skull in Porter County that appears to date back several decades. Authorities say the skull was uncovered off of Meridian Road, just north of US 6, by the Precision Pipeline Company during excavating work on the new Enbridge pipeline late Monday morning. Pipeline contractors immediately ceased operations and contacted the Porter County Sheriff’s Department. Porter County Coroner Chuck Harris also responded. Sheriff’s Detectives processed the scene but did not locate any other remains at this time. After reviewing digital photographs of the skull, Forensic Anthropologist Dr. Stephen Nawrocki from the University Of Indianapolis believed the skull to be of a pre-1940 origin. Indiana Conservation Officers took custody of the remains and instructed the Precision Pipeline Company to cease excavation where the skull was uncovered. The DNR Historical Preservation & Archaeology Division will be analyzing the remains to determine the age and origin of the skull.
