Natalee Holloway: A Case That Captivated The Nation
A False Confession
In 2006, a 41 year old elementary school teacher named John Mark Karr confessed to having killed JonBenét Ramsey after being arrested in Bangkok, Thailand. He claimed that he had drugged, assaulted, and killed her although he said that the murder had been accidental.

Despite what initially seemed to be a huge breakthrough in the case, authorities were unable to find anything that linked the alleged murderer to the crime scene. His claims of having drugged JonBenét were also suspicious as the autopsy found no drugs in her body. DNA samples from Karr also did not match any found on her.
