Italian authorities reveal initial findings in Bayesian manslaughter investigation following tragic sinking, citing ’mistakes’ made

Italian prosecutors release initial findings in manslaughter investigation into the Bayesian disaster, following claims that the luxury yacht was "unsinkable."

It sank in the early hours of Monday morning when it was ensnared in a storm off the northern coast of Sicily, killing seven including tech tycoon Mike Lynch and his 18-year-old daughter Hannah.

Hannah’s body was the last to be recovered on Friday, as authorities now shift their attention to how the horror unfolded.

Speaking on Saturday, Chief Prosecutor of Termini Imerese Ambrogio Cartosio said investigators "cannot exclude anything at all" and that it "could be a question of homicide".

He said: "We feel close to the families, the families have undergone this loss.

"And what’s even more painful would be in fact if the development of the inquiry were to demonstrate that this tragedy, this terrible tragedy, was caused by behaviours that were not perfectly in order with regard to the responsibility everybody had.

"I’d like to officially communicate with you that the prosecutor has hypothesised that there could be in fact the question of homicide.

"But this is the beginning of the inquiry... We cannot exclude anything at all."

The probe is being centred on the crew’s responsibility.

Prosecutors confirmed they were "concentrating on this particular aspect."

Investigators are vowing to "discover how much they (the crew) knew and to what extent all the people (passengers) were warned".

It’s believed those who died were likely asleep when it capsized, meaning they couldn’t escape in time.

How a yacht at the size of the Bayesian - 56 metres long - capsized and sank to the seabed so swiftly is unclear.

A nearby sailboat remained unscathed while the Bayesian descended to doom, despite the "unsinkable" tag it was given by the chief of manufacturer Perini Navi.

Cartosio called the disaster "a very serious tragedy" and praised divers for being "so professional and so courageous".

He said it was "clear people were trying to hide in cabins on the left hand side".

Sicilian investigators has been speaking to the 15 survivors, including captain James Cutfield, to gain a sense of whether proper safety precautions were followed with wild weather forecast.

Skipper Cutfield, from New Zealand, is set to be grilled for further questioning, prosecutors confirmed on Saturday.

Marine experts have been scratching their heads over how the boat sank so quickly amid claims it should’ve been able to withstand a storm.

Perini Navi boss Giovanni Costantino slammed the crew onboard the vessel for making key "mistakes" before it plunged in just minutes.

Mr Costantino told The Sun: "Modern sailing ships, especially high-tech ones like the Perini, are designed to be extremely safe and stable.

“Even in very critical conditions, if procedures are followed, a sailing yacht like the Bayesian will return to an upright position.

"However, if the ship takes on water, this stability is compromised.

“Where the water entered will be determined by the investigators.

"What is certain is that the ship took on hundreds of thousands of litres of water."

A tornado that swept over the sea has been blamed for throwing the Bayesian upside down, but Mr Constantino disputed claims it had not been forecast and said it was "widely predicted".

Hannah, the 18-year-old student, perished alongside her tech tycoon dad Mike Lynch, 59, and five others in the yacht sinking on Monday.

Hannah and Mike - nicknamed Britain’s Bill Gates - went down alongside Morgan Stanley International bank chairman Jonathan Bloomer, his wife Judy Bloomer, Clifford Chance lawyer Chris Morvillo and his wife Neda Morvillo.

Fire service chief Girolamo Bentivoglio said divers were recruited from all over Italy to recover the bodies, which were found in cabins on the left-hand side.

He said the specialist divers were forced to negotiate "very little visibility due to the weather conditions".

He added: "The yacht obviously pinned to the right and obviously the (people) tried to go on the other side and then took refuge in their cabins.

"We found four or five bodies in the cabin on the left and there was another one in the third cabin on the left too, and obviously they were in the higher part of the wreck."

Autopsies are yet to be carried out, with a timeline on the investigation unclear given the wreck is 50 metres below.

Cartosio revealed the owner of the "Sir Robert" ship nearby the Bayesian sinking was heroic in saving the 15 who made it out alive.

He said: "The matter that we’re interested in is that at 4.32 in the morning, the coastguard were notified that there was a problem at sea.

"And the coast guard sent out a boat and the yacht that we’re talking about had already sunk.

"There were some divers who in fact were obtained from another ship that was 200m from the Bayesian.

"I think that in fact ... the owner of that ship, he was able to save most of the people who were onboard."

Expert diver Bertrand Sciboz told the BBC he was surprised how quickly it sank, but said no vessel is unsinkable.

He said: "Inquiries will find the reasons which mix together to make the final drama.

“You can have not one fact, but many small facts, which at the end make a big drama."

The specialist diver added a "very special operation" would be needed to extract the wreck, and the mast will likely have to be taken off first.

He said: “They will need to salvage the boat intact but I suppose they will have to take off the mast before.

“First, put the boat on its keel and then take off the mast.

She said: "Hannah often burst into my bedroom and lay down with me.

"Sometimes beaming with a smile, sometimes cheeky, sometimes for advice."
