Authorities Study Sea Floor Photos in Search for Natalee

Aruban authorities studied photos of the sea floor Friday as part of an investigation into the disappearance of missing U.S. teenager Natalee Holloway, prosecutors said.

The photos were taken during a four-day search led by coast guard ships off the coast of the Caribbean island earlier this week, said Mariaine Croes, a spokeswoman for the prosecutor's office.

Croes declined to specify what authorities hoped to find in the photos or to say how the search was related to Holloway's disappearance nearly a year ago.

The coast guard of Aruba and the Netherlands Antilles halted the search on Thursday and authorities declined to say whether it would resume amid what appeared to be renewed activity in the case.

Authorities on Saturday arrested Geoffrey van Cromvoirt, 19, saying he was suspected of "criminal offenses that may be related to the disappearance" of Holloway, but have not provided details.

His defense lawyer has said he has no connection to her disappearance.

The 18-year-old Holloway, of Mountain Brook, Alabama, was last seen driving away from a bar with three young local men on the final night of a high school graduation trip to the island.
