Olivia Jane Ward`s body has been exhumed for a second autopsy 15 years after she was buried in the Canaan Cemetery in Searcy County. Her parents have questioned official explanations of their 16-year-old daughter`s death. Ron and Mona Ward contend that state and county investigtors erred during the investigation. The girl was buried in 1989 after she died during a party with schoolmates at a cabin in the woods. The official cause of death was a broken neck from falling off a porch that was less than 10 inches off the ground. The Wards asked for another autopsy last month from Circuit Judge Charles Clawson Junior of Conway. Searcy County Sheriff Jerry Loggins doesn`t see any need to reopen the case, but said he would if the autopsy points to the need for more investigation.
