I heard on the news last night, during a discussion of Natalee Holoway, that her step father was asked by the police, the day after she went missing, if she had a seizure disorder, specifically epilepsy. He thought it was a strange question because she didn't and it seemed to come out of the blue. After hearing JVS's taped confession, it is now obvious where the question could have come from and it suggests a police coverup. I also think that there was no "Daury" with the boat. I think it was his father.
