Investigators have identified the suspect in the death of JonBenet Ramsey as John Mark Karr. Federal officials, speaking on condition of anonymity, say Karr is 42 and is already being held in Thailand on unrelated sex charges. According to the Ramsey family's lawyer, Karr is a schoolteacher who once lived in Conyers, Georgia, not far from Atlanta, where the Ramseys now live. The lawyer isn't saying if the Ramseys know Karr. But in a statement, JonBenet's father, John Ramsey, says he and his wife had been aware that there was a suspect. Patsy Ramsey died in June, but her husband says she knew of the investigation. JonBenet Ramsey was a six-year-old beauty queen. Her body was found in the basement of the family's home the day after Christmas, 1996.
