Underwater tragedy in Maldives leaves families searching for answers after cave deaths

Monica Montefalcone, 52, an associate ecology professor at the University of Genoa, and her daughter, Giorgia, 20, were among the dead, according to The Associated Press (AP).

"Something must have happened," he said in a different interview with an Italian television station, according to AP.

Gianluca Benedetti was found dead near the cave entrance shortly after the group disappeared. 

The cause of the deaths remains under investigation.

Vaavu Atoll is a chain of islands in the central Maldives, located southwest of Sri Lanka and India.

Authorities were alerted after the divers failed to surface by midday Thursday, when weather conditions were rough, per AP.

Italy's Foreign Ministry said the group "apparently died while attempting to explore caves at a depth of 50 meters (164 feet)," the AP reported.

Maldivian presidential spokesperson Mohamed Hussain Shareef told reporters the cave was exceptionally dangerous.

"The cave is so deep that divers even with the best equipment do not try to approach," he said.

Local officials described the tragedy as the Maldives' worst single diving accident.

An Italian pulmonologist told local outlet Adnkronos that the incident "suggests a problem with the tanks."

"It is likely that something did not work in the tanks," Micheletto told the local outlet. 

"The people using them could not have noticed: Checks are the responsibility of those who produce and manage the equipment."

Alfonso Bolognini, president of the Italian Society of Underwater and Hyperbaric Medicine, said there are several possible explanations, including "an inadequate breathing mixture that can create a hyperoxic crisis," according to Adnkronos.

Bolognini also suggested panic may have contributed to the deadly dive, according to Italian newswires.

"Inside a cave at 50 meters deep, all it takes is a problem for one operator or a panic attack for one diver," he said.

"In these cases, the panic component could lead to even fatal mistakes."

A perilous search for the bodies of the divers was halted Saturday after a military diver died during the mission.

The Italian Foreign Ministry said the cave system consists of three large chambers connected by narrow passages. Rescue teams explored two chambers Friday but were forced to stop because of decompression risks.

Officials are now awaiting the arrival of three Finnish cave-diving specialists to reassess the operation.
