He was not even sure she was dead when he had her body dumped in the ocean. ABC News:
In surveillance recordings aired on a Dutch TV special this evening, Joran van der Sloot, a former suspect in the disappearance of Natalee Holloway, said the American teen appeared lifeless on an Aruban beach three years ago during a romantic tryst, and "she'll never be found."
"I know what happened to that girl," van der Sloot announced during 20 hours of private conversations secretly recorded by crime reporter Peter R. de Vries.
Her body, van der Sloot said, had been dumped in the ocean by a friend with a boat.
"We're on the beach," he said on the recordings, according to the Dutch TV show. "Suddenly, she wasn't moving any more."
Nowhere on the recordings does van der Sloot display any emotion about the young woman he said he disposed of that night on the beach so far from home.
"I didn't even feel bad about it," he said at one point. "I didn't lose a night of sleep over it. I thought, 'I have to go on.'"
Could there finally be justice for Natalee? Maybe, if van der Sloot is telling the truth here. He claims he was lying, which he is known for.
Van der Sloot now claims he was lying in the secretly recorded conversations with Patrick van der Eem, a person he thought was a friend, but who was secretly working undercover for de Vries and his team of Dutch crime reporters.
The tale van der Sloot told on the tapes clearly contradicted his original story that he left the apparently intoxicated Holloway sleeping on the beach and did not know what happened to her after that.
In one taped conversation, van der Sloot told van der Eem that Holloway visibly convulsed "like a movie," that she was shaking "a lot."
"Did you try CPR on her?" asked van der Eem.
"Of course, I tried everything," van der Sloot said. "I tried to shake her. I was shaking the bitch. ... I was like, 'What is wrong with you man?' ... I almost wanted to cry. ... Why does this s*** have to happen to me?"
He admitted his first call wasn't to the hospital or to the police -- but to a friend to help dispose of the body.
He had her body dumped in the ocean and did not try to get her help. Was he even sure she was dead?
Van der Sloot said on the tape that his Aruban friend, alone, took Holloway out to the ocean and dumped her apparently lifeless body.
But was she really dead?
"How were you so sure she was dead, Joran?" van der Eem asked on the tapes. "You know, people can also go into a coma."
"Yeah, I wasn't sure about that, but it really startled me to death," van der Sloot admitted.
"But she could also have been in a coma," van der Eem said.
"That's possible too huh," van der Sloot answered. "That's very possible."
It's hard to believe Greta believed this piece of scum. Or more accurately she was "inclined to believe him".
