Joran van der Sloot, the Dutch national suspected in the 2005 disappearance of Natalee Holloway who will soon arrive in the U.S. to face charges that he extorted her mother, once claimed that he had shoved the Alabama teen to the ground so hard she that hit her head on a rock and died, according to court documents. …

As part of the alleged $250,000 extortion plot, van der Sloot allegedly told a lawyer for Beth Holloway, Natalee’s mother, that the 18-year-old’s body was buried inside the foundation of a house in Aruba, the Caribbean nation where she vanished on May 30, 2005, during a high school graduation trip.

“Van der Sloot went on to admit that he had been with Natalee on the night of May 29/30, 2005, and that he had thrown her to the ground after she had attempted to stop him from leaving her,” page six of a federal affidavit alleges. “Van der Sloot claimed that when she fell down, she hit her head on a rock and died as a result of the impact.”

[This kind of sadistic scheme will undermine any claim van der Sloot can make to have incapacitating mental illness as a defense. I bet prosecutors can’t wait to make that argument in court. — Ed]
