The Natalee Holloway disappearance case has become harder to solve because the main suspect's father has died. Crime reporter Peter R. de Vries told Radio Netherlands Worldwide,
"It's always sad if a relatively young person suddenly dies. It's also a painful loss for the investigation into the Holloway case. I am convinced that Mr Van der Sloot knew more than he had told us. He may have helped his son cover up parts of the truth."
