(CLYDE TOWNSHIP) -- Authorities say a human skull was found in Mill Creek in St. Clair County's Clyde Township Thursday afternoon. Port Huron resident Frank Kozlowski was wading in the water in the Beard Hills State Game Area around 5 p.m. when he reached up under a log in the water and felt something unusual--a human skull. Kozlowski immediately called police. Dive team members from the St. Clair County Sheriff's Office were sent to the location where the skull was found. During their search, other bones were located in water 3-4 feet deep. The skull and bones have been turned over to the medical examiner.
