None of the victims were found with water in their lungs, suggesting they didn’t drown, according to the autopsy results.

Four victims of Mike Lynch's sunken superyacht were likely trapped in air bubbles before suffocating, La Repubblica reported, citing autopsy results.

Four people who died when the Bayesian superyacht sank off the coast of Sicily last month suffocated after oxygen depleted in a pocket of air they were trapped in, the Italian news agency Ansa has reported.

Civil protection officials said they believe the ship was struck by a tornado over the water, known as a waterspout, and sank quickly.
