The body of a woman was recovered from the wreck of the Bayes yacht and has not yet been identified.

Italian rescue workers have brought ashore the body of the last missing person after a superyacht sank off the coast of Sicily this week, according to the coast guard.

The body of a woman was found on Friday. Her official identification is still pending, the Italian coast guard told the Associated Press news agency.

Hannah Lynch, the 18-year-old daughter of British technology magnate Mike Lynch whose luxury yacht capsized on Monday, was reportedly the latest person to go missing.

The discovery of the body brings the death toll to seven. This concludes a five-day search operation involving specialized divers, boats from several rescue services and helicopters.

Lynch was one of five dead passengers whose bodies were recovered on Wednesday and Thursday from inside the yacht, which was anchored off the harbor of Porticello, near Palermo, as the storm hit at dawn.

The body of the only deceased crew member, cook Recaldo Thomas, was recovered near the wreck on Monday.

Lynch, a celebrated technology entrepreneur and investor, had invited friends and family onto the Bayesian, a 56-metre superyacht with 22 people – 12 passengers and 10 crew – on board, to celebrate his recent acquittal in a massive fraud case in the US.

The ship was hit by a waterspout – similar to a mini-tornado – which caused it to sink to a depth of 50 metres (164 feet) below sea level within minutes.

Fifteen people, six passengers and nine crew members, were rescued, including Lynch’s wife Angela Bacares.

A judicial investigation has been launched into the sinking of the ship, which has baffled marine experts who believe that a boat such as the Bayesian, built by Italian luxury yacht builder Perini, should have withstood the storm.

Giovanni Costantino, CEO of Italian Sea Group, which owns Perini, said the shipwreck was the result of a series of “indescribable, unreasonable errors” by the crew and ruled out design defects.

The yacht’s captain, James Cutfield, and his eight surviving crew members were questioned by police but have not commented publicly on the disaster. Investigating prosecutors will hold a press conference on Saturday.

Pulling the wreckage out of the sea, where it now appears to be lying intact on its right side, could help investigators figure out what happened, but the operation is likely to be complex and expensive.

Other victims include Christopher Morvillo, one of Lynch’s American lawyers, and his wife Neda, as well as Jonathan Bloomer, chairman of Morgan Stanley’s London-based investment banking subsidiary, and his wife Judy.
