was the case not solved, it was not even clear that a crime had been committed. Professor Crisje Brants, in the same seminar, also criticized De Vries' methods. On November 24, Fox News aired an interview with Van der Sloot in which he alleged that he sold Holloway into sexual slavery, receiving money both when Holloway was taken, and later on to keep quiet. Van der Sloot also alleged that his father paid off two police officers who had learned that Holloway was taken to Venezuela. Van der Sloot later retracted the statements made in the interview.

Aruban authorities sent divers to investigate, but no remains were ever recovered. Van der Sloot's extortion of Holloway family On March 29, 2010, Van der Sloot contacted John Q.
