Days later, when it looked as though Joran and his two friends would be arrested, the elder van der Sloot offered legal advice.
"I explained to them the procedures ... so that they would not panic," he said to Dutch TV Nova. "That was sufficient for the prosecutor to suspect that I was an accomplice."
But lead prosecutor Caren Janssen says her investigators have proof the father-son talk went a lot further.
Also heard through an interpreter, she told Dutch TV Nova, "The father talked to the boys and told them that without a body, there wouldn't be a case. And that is something that, possibly, we can't rule it out, has played an important role in the way the boys told their stories."
Those stories, Cobiella notes, have brought investigators no closer to knowing whether Holloway is alive, or whether a crime has been committed. And the one person who is certain to know the truth, Holloway herself, is no closer to being found.
