Autopsies conducted on victims of the superyacht Bayesian, which sank off the coast of Sicily on August 19, confirmed drowning as the cause of death for U.S. lawyer Chris Morvillo and his wife Neda, among seven casualties. British tech billionaire Mike Lynch and his 18-year-old daughter Hannah were also among the deceased, while Lynch's wife Angela survived along with 14 others. The yacht sank during a sudden storm attributed to a localized downburst, and investigations are underway into the captain and crew's potential negligence. Prosecutors are planning further autopsies for other victims, including Lynch and the yacht's cook, Recaldo Thomas. The tragedy has drawn attention due to Lynch's involvement in a previous high-profile legal case regarding the sale of Autonomy to Hewlett-Packard. Raising the sunken yacht for examination is expected to provide crucial evidence for the ongoing investigation.
