PORTICELLO, Italy—Divers resumed a search on Wednesday for survivors after British tech entrepreneur Mike Lynch’s yacht sank off the coast of Sicily two days ago, though hopes dwindled of finding the six missing people alive. The British-flagged Bayesian, a 56-metre-long (184-ft) superyacht, was carrying 22 people and was anchored off the port of Porticello, near Palermo, when it capsized during a fierce storm on Monday. Fifteen people survived, one crew member’s body was recovered and six passengers remain unaccounted for, including Lynch, his 18-year-old daughter, and Jonathan Bloomer, a non-executive chair of Morgan Stanley International.

Underwater inspection of the wreck resumed early on Wednesday after being paused late on Tuesday, the fire department said on social media. It earlier described the operations as “long and complex.” He sold the firm to HP for $11 billion in 2011, after which the deal spectacularly unravelled with the U.

S. tech giant accusing him of fraud, resulting in a lengthy trial. Lynch was acquitted on all charges by a jury in San Francisco in June.

The other missing passengers are Bloomer’s wife Judy, Clifford Chance lawyer Chris Morvillo and his wife, Neda Morvillo. Morvillo represented Lynch in the San Francisco trial, while Bloomer was a character witness on his behalf. Experts have been at a loss to explain how a large luxury vessel, presumed to have top-class fittings and safety features, could have sunk within minutes, as recounted.
