Tink, in the US he is charged with extortion, but it sounds like they want him held until they can conjure up a murder charge:
Van der Sloot has been indicted in the U.S. on charges that he extorted $25,000 from the mother of Natalee Holloway. The 18-year-old from Mountain Brook, Ala., vanished while on a class trip to Aruba. She was last seen leaving an Oranjestad nightclub with van der Sloot, then a 17-year-old Dutch honors student living in Aruba. Holloway's body has never been found, and van der Sloot has not been charged in her disappearance.
Prosecutors said that in exchange for the money he received from HollowayÂ’s mother, van der Sloot promised to reveal how Holloway died and the location of her body.
Â….According to Griffith, whose most renowned case, involving an American incarcerated in a Turkish prison, was the basis for the film and book "Midnight Express," Van der Sloot would likely face a five- to 10-year sentence in the U.S. for the alleged extortion. But, it is possible additional charges related to Holloway could be filed later.
