The Mason County Sheriff's Department is releasing more details about the adult human skull fragment that was found last month near Ludington.
Twelve bones fragments were found by a woman walking along Morton and Chauvez roads about five miles south of Ludington and were sent to Michigan State University forensic anthropologists for further testing. University scientists determined one of the twelve to be an adult human skull fragment.
MSU has since found markings on the fragment that determined that an autopsy had already been performed, and that a cause of death had been ruled from it.
Officials spoke with residents near the site to see if anyone had buried loved ones on their property, and scanned the area for any grave sites, and did not find anything.
MSU will be keeping the remains. Mason County Sherriff, Kim Coles, says that since there is no indication of foul play, they will not be investigating this any further unless additional information comes to light.
