Four bodies were recovered inside the Bayesian superyacht on Wednesday, more than two days after it sank off the coast of Italy, setting off an exhaustive search for six missing people, including British tech entrepreneur Mike Lynch.

Two of the bodies discovered earlier on Wednesday were brought to shore. One body recovered was a heavily built man, Reuters reported.

Six of the ship's 22 passengers, including Lynch and his 18-year-old daughter, went missing after the yacht plunged under the water just before 5 a.m. on Monday as a storm swept across the area. Americans are among the missing, officials have said.

The U.K.-registered yacht belonged to Lynch's wife, Angela Bacares, who was also on board and was rescued. The tech tycoon was recently acquitted on fraud charges after a year under house arrest.

Ricardo Thomas, the ship's cook, was found dead on Monday, according to the coast guard.

The rescue mission saw a diving team, helicopters and multiple coast guard ships deployed to search the water. Fifteen people were pulled from the water on Monday, and eight were hospitalized in stable condition.

A 'black swan event'?Experts puzzle over why Bayesian yacht sank

An investigation opened by local prosecutors into the cause of the disaster is ongoing. Experts have pointed to a water spout, a tornado over the water that can travel up to 120 mph, that formed during the storm, as well as the heavy weight of ship's mast, one of the largest in the world.

The 184-feet-long ship was made by Italian ship manufacturer Perini in 2008.

Lynch set off on the cruise late last month to celebrate his acquittal on fraud charges in the U.S. that marked a decade of legal challenges, the Associated Press reported.

One of his lawyers and a character witness for Lynch during the trial were also on board and vanished when the boat went down. Authorities have not yet disclosed the identities of the four people found.

Here are the passengers who were declared missing.

Mike Lynch and Hannah Lynch

Mike Lynch, 59, is co-founder of Britain’s largest enterprise software, Autonomy, which was sold to Hewlett-Packard in 2011, and founder of venture capital fund Invoke Capital. 

Sometimes known as “Britain’s Bill Gates,” Lynch was slapped with charges after HP said it had uncovered deceit and a major accounting scandal within the firm. He spent a year on house arrest after being extradited from the UK.

In early June, at the end of a 12-week trial, a San Francisco jury acquitted Lynch of wire fraud and conspiracy to commit wire fraud. He was also cleared on a charge of securities fraud later that month.

Lynch and Bacares have two daughters and six dogs, all named after engineering parts, according to the U.K.’s Sunday Times in a profile of Lynch from last month.

Lynch’s 18-year-old daughter, Hannah, was also among the missing. She was preparing to study English literature at Oxford University, according to the Sunday Times. 

Hannah is the younger of Mike Lynch’s two daughters, the Times reported. Mike Lynch told the outlet that his daughters had grown up with their father being publicly accused of fraud. 

Jonathan Bloomer and Judy Bloomer

Jonathan Bloomer is the non-executive chairman of both Morgan Stanley International and the insurer Hiscox, among other companies. Bloomer acted as a character witness on Lynch’s behalf during his fraud trial. 

Hiscox Chief Executive Aki Hussain told Reuters in a statement that the firm was deeply shocked and saddened and their thoughts were with all those affected. 

Bloomer’s twin brother, Jeremy, told BBC that he is processing the news and the family is waiting to hear updates.

“He was my elder by half an hour, so, it means a lot when you lose a twin brother,” Jeremy Bloomer told BBC. “We’ll still wait and see, so it’s fingers crossed.”

Jonathan Bloomer’s wife, Judy, is a psychotherapist of nearly three decades and former teacher. She specializes in anxiety and stress. She studied English language and literature at Homerton College in Cambridge.

Christopher Morvillo and Neda Morvillo

A lawyer with Clifford Chance, Chris Morvillo was among the team that represented Mike Lynch during his trial. Morvillo is an American citizen. 

He was an assistant U.S. attorney for the Southern District of New York from 1999 to 2005, and he worked on the criminal investigation stemming from the 9/11 terrorist attacks. 

Morvillo was a graduate of Fordham University School of Law and Villanova University. 

Neda Morvillo, his wife, owns a hand-crafted jewelry company under her maiden name, Neda Nassiri. The company’s website said she has been designing and making jewelry for over 20 years.

In a post on LinkedIn after the conclusion of Lynch’s trial, Chris Morvillo acknowledged his family for their support during the case. 

“And, finally, a huge thank you to my patient and incredible wife, Neda Morvillo, and my two strong, brilliant, and beautiful daughters, Sabrina Morvillo and Sophia Morvillo.  None of this would have been possible without your love and support. I am so glad to be home. 

And they all lived happily ever after…."
