(CBS/AP) The father of missing American teenager Natalee Holloway says he and a team of experts will search for his daughter's body in waters off Aruba following the recent re-arrest of three suspects in her 2005 disappearance.

While authorities searched the sea to depths of 330 feet, Dave Holloway told The Associated Press that he believes his 18-year-old daughter was thrown into deeper waters - a belief based on talks with a police official and a private forensic expert.

Holloway said a private boat owner is providing divers, sonar equipment and 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

Holloway said he would alert police on the Dutch Caribbean island if anything is found.

Authorities announced Wednesday they had found "new incriminating evidence" and re-arrested three men - Dutch student Joran van der Sloot and brothers Satish and Deepak Kalpoe of Suriname - on suspicion of involvement in voluntary manslaughter and causing serious bodily harm that resulted in Holloway's death.

Holloway said the re-arrest of three suspects in the case has renewed some hopes that he might finally find out what happened to his daughter

"It just gives us hope that they're still involved, and maybe we'll finally get some answers," Dave Holloway told CBS News Correspondent Kelly Cobiella.

The 18-year-old from 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.

A search by hundreds of volunteers, soldiers, police and FBI agents - even Dutch air force planes - turned up no trace of her.

Holloway's father, Dave Holloway, is a graduate of Jonesboro Westside High School in Arkansas who now lives in Meridian, Miss. The teenager has other family members living in the Jonesboro area, a grandmother in Pine Bluff, Ark., and an aunt in El Dorado, Ark.

Van der Sloot, seen left, and the Kalpoe brothers were first detained in June 2005, but they denied involvement in the woman's death and a judge later released them for lack of evidence.

Van der Sloot, 20, was re-arrested in the Netherlands, where he was attending a university. The Kalpoe brothers - Deepak is 24, Satish, 21 - were taken into custody in Aruba.

Van der Sloot's lawyer, Rosemarie Arnold, played down the arrest during an interview with the CBS Early Show's Maggie Rodriguez.

"We heard that there was new evidence. We don't know what the evidence is. We know that it's not a body, and we don't even know if it has anything to do with Joran." Arnold told Rodriguez. "When they arrest somebody in Aruba they could just doing it to detain them and question them and in this case that's what we expect to happen."
