20/20 will air a taped video confession of Joran Van der Sloot confessing to his buddy that he was with Natalee Holloway when she died on the beach in Aruba back in 2005.

In the secretly obtained footage, Van der Sloot said Holloway was drunk and that she began shaking and slumped down on the beach as they were kissing.

“Suddenly she started shaking and then she didn’t say anything,” Van der Sloot said in Dutch. “I would never murder a girl.”

He said he then called a friend, called “Daury,” who used his boat to dump the body at sea. Asked by Van der Eem how he could be so sure that Holloway was dead and not just “in a coma,” Van der Sloot admitted that he wasn’t.

Joran is now claiming he was lying in the secretly taped video confession and just saying what his buddy wanted to hear.  Yeah, that makes a lot of sense to lie about being there when Natalee died and then dumping her body in the ocean.

Lock this guy up!

The tape will be aired tonight on 20/20: The Final Hours of Natalee Holloway tonight at 9:30pm.
