Report: Phone Conversations Could Be New Evidence in Natalee Holloway Case

Recorded phone conversations between three suspects in the disappearance of Alabama teen Natalee Holloway could be the evidence needed to propel the case forward, according to a Dutch newspaper.

Citing anonymous detectives in Aruba, De Telegraff reported Friday that police have taped conversations between Joran van der Sloot and brothers Deepak and Satish Kalpoe from earlier this year which contradict their earlier testimony regarding Holloway's disappearance.

The Kalpoe brothers were arrested in Aruba Wednesday while police in the Netherlands took in Dutch college student van der Sloot.

"New material in the investigation" led to the arrests, prosecutors said — although they refused to reveal the nature of the new evidence.

Holloway, of Mountain Brook, Ala., was last seen leaving a bar with the three men on May 30, 2005, hours before she was scheduled to fly home with high school classmates celebrating their graduation on the Dutch Caribbean island. She was 18 at the time.

Hundreds of volunteers, Aruban soldiers, police and FBI agents — even Dutch air force planes — searched for the missing teen, but no trace was ever found.

Van der Sloot and the Kalpoe brothers previously had been detained on suspicion of involvement in the woman's death, but they denied involvement and a judge released them for lack of evidence.

The Kalpoes' attorney, David Kock, did not return a call for comment Thursday, but told a local radio station that the latest arrests were "an action of despair."

"There was no reason for their arrest now," he said. "We will take all kinds of measures to give our clients their freedom as soon as possible."

Holloway's father said Thursday that he and a team of experts will now search for his daughter's body in the waters off Aruba.

Dave Holloway told The Associated Press he believes his daughter's body was thrown into the ocean in deeper waters than those already searched. He said he based that belief on conversations with a police official and a private forensic expert.

Holloway said a private boat owner is providing divers and sonar equipment with the ability to map the ocean floor.

"It's like this: we've searched all the land areas ... It's common knowledge on the island that if someone were to dispose of the body, it would be out in the ocean," he said by telephone.

Authorities never searched in waters deeper than 330 feet, so the family will do so now that it has the capability, equipment and expertise, Holloway said, adding that police would be alerted if anything is found.

"I hope I'm not going to be disappointed," Dave Holloway said. "We've seen these arrests and re-arrests in the past."

Van der Sloot's mother, Anita, denied her son was re-arrested and said he was merely being taken to Aruba "for a final reconstruction."

She said by telephone that investigators had recently questioned her family and that of the Kalpoe brothers.

"The questions they asked were so obvious: things like, 'Why did Joran leave his shoes on the beach,"' she said, referring to the place where her son said he kissed Holloway alone before her disappearance. "I think it's ridiculous after two-and-a-half years to be doing this."

Van der Sloot was expected to arrive in Aruba sometime Friday evening.

In April, investigators from the Netherlands dug around the home of van der Sloot's family for two days without revealing what prompted the search. Then in May, Dutch and Aruban investigators visited the home where Deepak and Satish Kalpoe live with their parents for what authorities termed an "inspection."
