Crime novelists, detectives and many average Americans have theories about who killed JonBenet. John reveals what he thinks happened the night his daughter was murdered.
"We believe they came in while we were out, waited for us to go to bed ... and took JonBenet from her room," he says. "I've always said I don't know anybody this evil, or I've not had anybody around me this evil. This was a horribly evil act."
Over the years, John says people have emerged as potential suspects...some who even seemed to be "the one." In 2006, John Mark Karr, a teacher from Georgia, made headlines when he confessed to killing JonBenet. However, DNA evidence failed to place him at the scene of the crime.
When John heard about Karr's claims, he says he was hopeful but not convinced. "We had had other people confess," he says.
