He and Natalee Holloway lied down on a beach together at night and started kissing. As the kissing continued, van der Sloot started touching her. When Holloway said no and told van der Sloot to stop, he continued touching her anyway.
"She ends up kneeing me in the crotch," van der Sloot said.
Van der Sloot said he stood up and kicked her "extremely hard" in the face. Then he found a large cinderblock and hit her with it. Seeing what he had done, he moved her body into the ocean until the water was up to his knees and he pushed her out to sea.
Beth Holloway said van der Sloot's confession was verified with a polygraph test.
Joran van der Sloot admitted to killing Natalee Holloway on Aruba beach in confession revealed in extortion case - CBS News
Joran van der Sloot admitted to killing Alabama teenager Natalee Holloway in Aruba in 2005 in a confession that was revealed publicly Wednesday as he entered a plea deal with federal prosecutors in an extortion case stemming from the disappearance that received international attention.
"Joran van der Sloot is no longer the suspect in my daughter's murder," Holloway's mother Beth Holloway told reporters outside the federal courthouse in Birmingham, Alabama, after a plea and sentencing hearing for the 36-year-old Dutchman. "He is the killer."
Van der Sloot confessed that he killed Natalee Holloway while she was on a high school graduation trip to the Caribbean island nation in an interview that his attorney conducted. The interview was provided to U.S. authorities as part of a plea deal for federal charges that van der Sloot tried to extort a quarter-million dollars from Beth Holloway in exchange for information about her daughter's death.
