What began as a daring scuba adventure in the Maldives ended in horror this week after five Italian tourists never resurfaced from a deep-water cave expedition. Officials are scrambling to determine what went wrong during the 160-foot dive, as theories swirl over whether powerful currents, rough weather, panic or even the terrifying effects of oxygen toxicity triggered the deadly tragedy. “It’s likely that something went wrong with the tanks,” pulmonologist Claudio Micheletto told Italian outlet Adnkronos on Thursday after all five divers perished during the fatal excursion.
