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.

Rescue crews brought four body bags ashore at Porticello. Salvatore Cocina, head of the Sicily civil protection agency, said a fifth body had been located. Divers on-scene said they would try to recover it on Thursday while continuing the search for the sixth.

The discovery made clear the operation to search the hull on the seabed 50 meters (164 feet) underwater had quickly turned into a recovery one, not a rescue, given the amount of time that had passed and with no signs of life over three days of searching. The British-flagged Bayesian, a 56-metre-long (184-ft) 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. Lynch, 59, was one of the UK’s best-known tech entrepreneurs and had invited friends to join him on the yacht to celebrate his acquittal in June in a major U.

S. fraud trial. His body was brought ashore in a blue bod.
