The body of British tech magnate Mike Lynch was retrieved on Thursday from the wreck of his family yacht that sank earlier this week off the coast of Sicily during a violent storm, a senior Italian official said. Lynch’s 18-year-old daughter Hannah is still unaccounted for, interior ministry official Massimo Mariani told Reuters after being briefed by the emergency services. The bodies of four other people who vanished when the boat went down were recovered from the yacht on Wednesday. The British-flagged Bayesian, a 56-metre-long superyacht carrying 22 passengers and crew, was anchored off the port of Porticello, near Palermo, when it disappeared beneath the waves in a matter of minutes after the bad weather struck in the early hours of Monday.
