Authorities will search once again for a missing U.S. teen after an American couple took an underwater picture of what they believe might be Natalee Holloway's remains, a spokeswoman for the prosecutors' office told The Associated Press on Saturday.
A police diving team will soon do preliminary work at the spot where officials believe the picture was taken, spokeswoman Ann Angela said.
It is too early to say whether the tip is more viable than the other numerous ones authorities have received, Angela said.
"It could be a skull, it could be a stone, it could be anything," she said. "That's what we're trying to figure out."
The couple cannot pinpoint the exact location, but a local resident believes he can find the spot, Angela said.
On Thursday, a newspaper in Pennsylvania reported that a photo taken last fall by the visiting couple, John and Patti Muldowney, of Manheim, Pa., had been turned over to the FBI.
The 18-year-old from Mountain Brook, Ala., disappeared while on vacation in Aruba in 2005.
