Four individuals who perished when British tech tycoon Mike Lynch's yacht Bayesian sank off Sicily on August 19 reportedly died from suffocation while trapped in an air pocket. Autopsies revealed that Morgan Stanley chairman Jonathan Bloomer, his wife Judith, lawyer Chris Morvillo, and his wife Neda succumbed to what has been termed 'atypical drowning,' a situation where victims ran out of oxygen. Lynch and his daughter Hannah's autopsies are pending, with initial examinations suggesting they may also have died similarly, as their bodies were found in separate cabins. The yacht sank during a sudden storm, leading to an investigation into the ship's captain and crew for potential manslaughter. Experts are puzzled as to why a luxury vessel like the Bayesian sank so rapidly despite being designed to withstand severe weather. Investigators continue to probe the circumstances surrounding the tragedy, with forensic tests expected in the coming weeks.
