Italian prosecutors have expanded their investigation into the sinking of the British-flagged superyacht Bayesian, which resulted in the deaths of seven people, including British tech magnate Mike Lynch and his daughter Hannah. The yacht's captain, James Cutfield, and two crew members, Tim Parker Eaton and Matthew Griffith, are being investigated for possible manslaughter and culpable shipwreck charges. Cutfield has exercised his right to remain silent during questioning, citing exhaustion and the need for his legal team to gather more information. The incident, which occurred off the coast of Sicily on August 19, is suspected to have been caused by a 'downburst,' a powerful localized wind. Investigators are scrutinizing the responsibilities of the captain, crew, and the yacht's manufacturer, as the Bayesian was considered 'unsinkable.'
