New York (CNN) – When Patti Muldowney went snorkeling off the coast of Aruba last October, the Pennsylvania woman probably could not have imagined one of her underwater photos would renew interest in the nearly five-year-old Natalee Holloway case.

Could this photo off the coast of Aruba show human remains?

Three months after snapping travel pictures of 'colorful fish' on a disposable film camera during her Royal Caribbean cruise's first stop, Muldowney and her husband realized that one picture contains what they believe appear to be human remains.

"When I looked at that photo, I said, 'By darn, that certainly does look like a skeleton,"' John Muldowney said on HLN's Nancy Grace. "You can see the skull. You can see where the eye sockets were. You can see where the chin was," he said.

"It's lying flat on its back. And its arms are cradled around," Muldowney added. "You can almost see fingers. And then on the one sleeve it looks like some kind of maybe clothing that's deteriorating."

The couple, who took the photo to police and the FBI, says it was taken near an old shipwreck. However, there are several submerged ships in the area and their boat was far enough out to sea that they could not see the shoreline.
