When the body of six-year-old JonBenét Ramsey was found in the basement of her Boulder, Colorado, home in the winter of 1996, her murder captivated and horrified the US. The tragic and premature death of a young girl, the investigative errors associated with the case, the false confession from a would-be killer, the conspiracy theories about who the killer really is, and the odd behavior of her family make it one of the most famous and widely speculated-upon crimes of the 20th century. Nobody has ever been convicted of Ramsey's murder.
