Six people are missing, including a man dubbed the British Bill Gates, after a luxury yacht sank off the Sicilian coast.
British tech entrepreneur Mike Lynch — freshly acquitted from a decade-long trial — had invited his work colleagues aboard a trip through the Mediterranean coast when a freak storm saw the yacht sink within moments.
Fifteen people escaped from the sinking vessel. The search for the missing continues.
Here's what we know so far:
What happened?
The Italian coastguard said the yacht — the Bayesian — was anchored off the shore of port city Porticello, near the Sicilian capital Palermo, when it was hit by bad weather sometime after 4am on Monday, local time.
[Map] Eyewitnesses said it vanished quickly beneath the waves shortly before dawn.
Managers of the sailing vessel Bayesian, Camper & Nicholsons, confirmed to the ABC that the Bayesian encountered severe weather and subsequently sank.
"Our priority is assisting with the ongoing search and providing all necessary support to the rescued passengers and crew," they said.
"The wind was very strong. Bad weather was expected, but not of this magnitude," a coastguard official told Reuters.
Sicily's civil protection agency head, Salvo Cocina, said a waterspout — a tornado over the water — could have struck the yacht.
"They were in the wrong place at the wrong time," Mr Cocina added.
Storms and heavy rainfall had swept down Italy in recent days after weeks of scorching heat, lifting the temperature of the Mediterranean Sea to record levels and raising the risk of extreme weather conditions, experts told Reuters.
"The sea surface temperature around Sicily was around 30 degrees Celsius, which is almost 3 degrees more than normal. This creates an enormous source of energy that contributes to these storms," meteorologist Luca Mercalli said.
Captain Karsten Borner of the Sir Robert Baden Powell vessel told journalists he noticed the Bayesian nearby during the storm, but after it calmed he saw a red flare and realised the ship had simply disappeared.
Mr Borner said he and a crew member boarded their tender and found a lifeboat with 15 people, some of them injured, who they then took aboard and alerted the coast guard.
Search crews, including helicopters and divers, are continuing to search the wreckage, lying at a depth of 49 metres.
Specialist divers reached the ship on Monday but access was limited due to objects in the way, the fire brigade said.
The UK Marine Accident Investigation Branch is deploying a team of four inspectors to Italy to conduct a preliminary assessment.
The Foreign Commonwealth and Development office said it was "providing consular support to a number of British nationals and their families".
Sicilian prosecutors have also opened an investigation into the event.
Who is missing?
There were 12 passengers and 10 crew members aboard the yacht.
Mr Cocina said the crew and passengers hailed from a variety of countries, including Britain, the United States, Antigua, France, Germany, Ireland, Myanmar, the Netherlands, New Zealand and Spain.
Of the 22, one man is confirmed dead and another six people are still missing.
They are believed to be inside the hull, fire rescue spokesperson Luca Cari said.
Fabio Cefalù, a fisherman who said he responded to a flare from the vessel but found it sunk, said he stayed at the site for three hours without finding anyone.
"I think they are inside, all the missing people," he said.
Rescue teams recovered the body of the yacht's onboard chef on Monday, identified as Antiguan citizen Ricardo Thomas.
The still missing people include:
- Mike Lynch
- Mr Lynch's 18-year-old daughter, Hannah
- Jonathan Bloomer, chairman of global financial services company Morgan Stanley International
- Chris Morvillo, a lawyer at the British multinational law firm Clifford Chance. He worked on Mr Lynch's lawsuit against Hewlett-Packard
- The identities of the remaining two missing are still unconfirmed
Who was rescued?
Fifteen people escaped from the sinking ship.
Eight have been hospitalised and others were taken to a nearby hotel.
Among those rescued were:
- Mr Lynch's wife, Angela Bacares, who was the owner of the yacht
- Charlotte Golunski and her one-year-old daughter, Sofia. Ms Golunski is a partner at Mr Lynch's firm, Invoke Capital. She says she momentarily lost hold of Sofia in the water but managed to hold her up above the waves until the lifeboat was inflated
- Ms Golunski's husband James Emslie
- New Zealand captain of the yacht James Catfield. He told Italian newspaper La Repubblica the crew didn't see the storm coming
- A lone Dutch citizen was identified by the Dutch foreign ministry as being rescued, but was not identified
Who is Mike Lynch?
Mr Lynch, once hailed as Britain’s king of technology, was recently freed from a Silicon Valley lawsuit that tarnished his legacy.
The 59-year-old Cambridge-educated mathematician created Autonomy, a search engine that could pore through emails and other internal business documents to help companies find vital information more quickly.
He received the OBE for his innovation in 2006.
He then sold the software to Hewlett-Packard (HP) for $US11 billion ($16 billion) in 2011, with Mr Lynch personally netting $US800 million.
HP valued Autonomy at $US46 billion ($68 billion) in the months leading up to the deal.
But the deal quickly turned sour after he was accused of forging the software's financial records to make the sale.
As part of a decades-long legal battle against HP, Mr Lynch was extradited to the UK on criminal fraud charges.
He steadfastly denied any wrongdoing, asserting that he was being made a scapegoat for HP's own bungling.
He was eventually cleared of all charges in June this year.
Although he avoided a possible prison sentence, Lynch still faced a bill from a civil case in London that HP mostly won during 2022. Damages haven't been determined in that case, but HP is seeking $US4 billion.
Following the San Francisco trial, Mr Lynch said he would return to the UK and do what he loved most: "[being with] my family and innovating in my field."
The holiday appeared to be something of a celebration after Mr Lynch's acquittal, with guests including some of the people who had stood by Lynch throughout the ordeal.
In a separate act of tragedy, Mr Lynch's co-defendant in the trial, Stephen Chamberlain, died on Monday, after a road accident left him critically injured.
Mr Chamberlain — Autonomy's former vice-president of finance alongside Mr Lynch — was hit by a car in Cambridgeshire on Saturday morning and had been placed on life support.
What is the Bayesian?
The luxury yacht is 56m long sailboat, with a 75m mast labelled as the tallest aluminium mast in the world.
It was previously named Salute when it flew under a Dutch flag.
The yacht, built in 2008 by the Italian firm Perini Navi, can accommodate up to 12 guests in six suites and a crew of 10, according to online specialist yacht sites. It was last refitted in 2020.
Online charter sites listed it for rent for up to 195,000 euros (about $AU 321,000) a week.
The ship also won a string of awards for its design.
Ms Golunski said the yacht had travelled through the Aeolian Islands, Milazzo and Cefalù before sinking.
It is likely the yacht's name would resonate with Mr Lynch because his PhD thesis and the software that made his fortune was based on Bayesian theory.
