Aruba ? Aruban prosecutors said Thursday that authorities are investigating new information in the Natalee Holloway case provided by a Dutch crime reporter.

Information from reporter Peter R. de Vries “may help considerably” in resolving what happened to the American, who vanished during a May 2005 school vacation to the Dutch Caribbean island, the prosecutor’s office said in a statement.

The statement did not specify the new material, but said it “may shed a new light on the mode” in which Holloway died and the “method by which her body disappeared.”

An attorney for Joran van der Sloot, a Dutch man who was a suspect in the case, said it was irresponsible for prosecutors to make the announcement without describing their evidence.

De Vries, who appeared late Thursday as a guest on a Dutch TV show, said he used a hidden camera in Aruba and the Netherlands to obtain images “that have proved to be very important.”

In a brief clip shown during the Pauw & Witteman news show, Holloway’s mother, Beth Twitty, says, “Look what they have done. Look what they have done to Natalie.”

It was not clear what she was reacting to.
