According to Natalee Holloway's mother, a man previously believed to have been responsible for the disappearance and presumed killing of the Alabama teenager in Aruba 20 years ago has now confessed to the crime. Joran van der Sloot, who had long been suspected, pleaded guilty to extorting money from the Holloway family. As part of a plea deal, he was required to disclose how Natalee died.
