Specialist divers from the Italian Navy's elite Comsubin unit are investigating the wreckage of tech tycoon Mike Lynch's yacht, Bayesian, which sank off the coast of Sicily during a freak storm on August 19, killing seven people including Lynch and his daughter. The divers have retrieved video surveillance equipment and are searching for more electronic data to understand why the yacht sank so rapidly. The yacht's captain, James Cutfield, and two British crew members are under investigation for multiple counts of manslaughter and causing a deadly shipwreck, although this does not imply guilt under Italian law. Autopsies revealed that some victims may have suffocated in air pockets rather than drowning. Plans are underway to raise the yacht for a thorough investigation. The tragedy has left maritime experts puzzled, as the yacht was built to withstand severe weather.
