New details are being released about the murder of a 9-year-old girl with ties to the Tri-State. Convicted sex offender John Couey, who confessed to killing Jessica Lunsford, is now telling police he buried her alive. Police say Couey claims to have sexually assaulted the girl for at least two days then hid her body in the ground behind his sister's home, where he'd been staying, about 150 yards away from the Lunsford home in Homosassa, Florida. Jessica's mother lives in Warren County, Ohio. Couey plead not guilty April 4th, to capital murder, burglary, kidnapping and sexual battery charges. Investigators say they're still trying to confirm every aspect of the suspect's story.
