Rescue crews unloaded three body bags from rescue vessels that pulled into port at Porticello on Wednesday.

Salvatore Cocina, head of the Sicily civil protection agency, said two other bodies had also been found in the wreckage.

The bodies of British tech entrepreneur Mike Lynch and his 18-year-old daughter Hannah were among those found inside one of the vessel’s cabins between two mattresses, The Telegraph reported.

The Bayesian, a 56-metre (184-foot) British-flagged yacht, went down in a storm early on Monday as it was moored about a kilometre (a half-mile) offshore. Civil protection officials said they believed the ship was struck by a tornado over the water, known as a waterspout, and sank quickly.

Fifteen people escaped in a lifeboat and were rescued by a nearby sailboat. One body was recovered on Monday – that of the yacht’s Antigua-born chef, Recaldo Thomas.

Lynch, 59, was one of the United Kingdom’s best-known tech entrepreneurs and had invited friends to join him on the yacht to celebrate his recent acquittal in a fraud trial in the United States.

Besides Lynch and his daughter, the other people unaccounted for after the disaster were Judy and Jonathan Bloomer, a non-executive chair of Morgan Stanley International; and Clifford Chance lawyer Chris Morvillo and his wife, Neda Morvillo.
