MILAN -- The first autopsies of victims of the Bayesian super yacht sinking off Sicily show drowning as the cause of death, authorities said Monday.

Among the seven individuals who perished when the Bayesian capsized in a sudden and severe storm on August 19th were U.S. attorney Chris Morvillo and his wife Neda. The autopsies, performed by medical examiners appointed by Palermo prosecutors, confirmed these findings.

Autopsies are scheduled for Wednesday on the remains of Jonathan Bloomer, head of Morgan Stanley’s London-based investment banking subsidiary, and his wife, Judy.

Autopsy reports for the remaining three victims, British tech entrepreneur Mike Lynch, who had organized the yacht trip to celebrate a recent legal victory, his 18-year-old daughter Hannah, and the yacht’s chef, Recaldo Thomas, are still pending.

Morvillo represented Lynch, a U.S. lawyer, in a fraud case involving the 2011 sale of Autonomy, a search engine company that became a symbol of British innovation, to Hewlett-Packard. The $11 billion deal went sour due to allegations that Lynch had manipulated financial records to inflate the value of Autonomy. He was acquitted in June.

Prosecutors are investigating the captain and two crew members to determine if they bear any responsibility in connection with the sinking. The 56-meter (184-foot) British-flagged luxury yacht went down during what seems to have been a sudden downburst, a localized powerful wind from a thunderstorm that spreads rapidly after hitting the surface. Fifteen people, including Lynch's wife, were saved.

Prosecutors stated that recovering the Bayesian and examining the yacht for evidence would provide crucial information for the investigation. No timeframe has been set for these actions.
