An Alabama judge accepted Joran van der Sloot's plea deal, meaning today, after almost two decades, the Dutch national admitted that he killed Alabama teen Natalee Holloway. In his proffer, a document in which the defendant offers information about a crime, he reportedly told the court that Holloway rejected his sexual advances, so he hit her, kicked her in the face, then bludgeoned her dead. He then put her body in the ocean. 

The confession was part of van der Sloot's plea deal on extortion charges. He was accused of trying to sell information to Beth Holloway on the location of her daughter's body for $250,000.

With his guilty plea, van der Sloot was sentenced to 20 years on the federal charges, which will run concurrently with his current sentence for the murder of Stephany Flores in Peru.
