BIRMINGHAM, Ala. (AP) — The chief suspect in the 2005 disappearance of Natalee Holloway has admitted to killing her. New details in the killing emerged Wednesday as Joran van der Sloot (pictured) pleaded guilty to extorting money from Holloway’s mother. He confessed in submitted court filings to bludgeoning Holloway to death on a beach in Aruba before dragging her body out to sea. He had sought a quarter of a million dollars from Holloway’s mother in exchange for information about the location of her daughter’s remains. His confession resolves a case that has captivated the public’s attention for nearly 20 years. His 20-year sentence for extortion will run concurrently with prison time he’s serving for another killing in Peru.
