New Evidence Emerges in Natalee Holloway Case

New evidence has emerged in the Natalee Holloway case that could shed light on how the Alabama teen died and the method by which her body disappeared, the prosecutor in Aruba said Thursday.

The Office of the Public Prosecutor of Aruba said in a statement that it has intensified its investigation after receiving new information from Dutch crime reporter Peter R. de Vries.

The prosecutor's office said it is working with the Aruban Police Corps to determine the validity of the new details in the case. The statement did not specify what the latest information was.

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

"They act quite frankly like clowns," said Joseph Tacopina, a New York attorney. "If they have a resolution, they should bring a case and stop talking about cryptic information."

De Vries' Web site said the information was gathered through "an ingenious hidden camera tactic" and will be revealed in a Dutch television program Sunday. It said the reporter traveled to Aruba last week to inform authorities of his findings.

"The mystery of Natalee Holloway will be solved Sunday," De Vries said on the Dutch television show RTL Boulevard, which showed him meeting Natalee's mother, Beth Twitty, at an Amsterdam airport. "It was a big operation that we worked on for months."

De Vries had a testy exchange earlier this month during a televised interview in the Netherlands with van der Sloot.

Van der Sloot, who was among the last people seen with Holloway, threw wine at De Vries after the reporter challenged his credibility.

Last month, prosecutors dismissed their case against Van der Sloot and two other suspects, brothers Deepak and Satish Kalpoe, saying they didn't have sufficient evidence to charge them or even prove a crime was committed. They cited the lack of a body as a major reason for ending the investigation into the role of the three young men in Holloway's disappearance.

Authorities have said the case could be reopened if new evidence surfaces.

Holloway was on a high school graduation trip to the Dutch Caribbean island in May 2005 when she vanished without a trace. She was last seen leaving a bar with van der Sloot and the Kalpoe brothers, who have been arrested a number of times but never charged with any crime.
