AOL News (March 25) -- Aruban authorities have called off an underwater search for the remains of missing American teenager Natalee Holloway, pending further investigation.
"It's a dead end," Ann Angela, a spokeswoman for the Aruba prosecutor's office, told CNN Wednesday.
The underwater search was prompted by a photograph of possibly human remains that a Pennsylvania couple, John and Patti Muldowney, took while snorkeling off Aruba.

This photo, taken by Patti Muldowney in Aruba in October, triggered a new search for the remains of Natalee Holloway. But the effort turned up nothing, Aruban authorities said.
The photo was captured in October in about 15 feet of water, but the film was not developed until December, according to John Muldowney. As they looked through the shots, Patti Muldowney remarked, "'My God, this looks like a skeleton,'" he said in a March 20 interview with AOL News. "And then we all looked and said, 'It sure does.' Our first thought then was that it was Natalee Holloway."
Holloway, 18, from Mountain Brook, Ala., disappeared May 30, 2005, while on a trip to Aruba to celebrate her high school graduation. Her body has never been found.
When authorities in Aruba learned of the photo, they contacted the tour company that had taken the Muldowneys to the snorkeling location. Divers then spent two days searching the area but were unable to locate any human remains. It is now their belief that the photo is of coral.
The announcement that remains were not found came as no surprise to at least one underwater expert.

Natalee Holloway, 18, disappeared on a trip to Aruba in 2005.Jack Fisher, founder and president of JW Fishers, told AOL News his initial thought was that the image was of an "outcrop of coral that happens to be lined up the way we would want to see it."
Fisher's company specializes in the design and manufacture of high-tech underwater search equipment.
Fisher also said he felt it unlikely that divers or high-tech equipment could locate the exact formation seen in the photo.
"In order for that configuration to show up in sonar, so that you also see it as a body not as a bunch of rocks, you would have to have the same approach and the same angle that the photographer was in," Fisher said. "It would be very difficult to do. If you came into it at a different angle, you would never think it was a body."
However, if the image was of a body, Fisher said it would not matter how you approached it.
"Even if you came in at a different angle, it would still look like a bod
