JEFFERSON COUNTY • Major Case Squad investigators are asking the public's help in finding a 25-year-old man who was apparently the last person to see a 3-year-old girl in the Barnhart area before she was found dead Monday morning.

The Jefferson County Sheriff's office is seeking William A. Harris, who is identified as white, about 180 pounds, with brown eyes and brown hair.

"William Harris was the last known person with care of the victim prior to her discovery," says the statement. "Upon arrival of law enforcement personnel he was unable to be located."

The statement asks that anyone with any information contact the Major Case Squad at (636) 797-6234, Sgt. Kausler st (636) 262-4882 or Crime Stoppers at 866-371-TIPS (8477).

The child's mother called police at about 6:30 a.m., and deputies discovered the child's body inside the home along 6600 Dry Creek Road, said Jefferson County Lt. Gary Higginbotham. He said the child had not been shot or stabbed but her body had "obvious signs of trauma."
