ITALIAN authorities are “investigating shipwreck and multiple counts of culpable manslaughter” after doomed super-yacht Bayesian capsized off the coast of Sicily. The Prosecutor's Office of Termini Imerese, led by Ambrogio Cartosio, is working to find out why the luxury vessel capsized off the coast of Porticello near Palermo shortly before 5am on Monday. It is investigating offences of shipwreck and multiple culpable murder - similar to the charge of manslaughter in the UK - against unknown persons, according to Italian media.

Investigators have been scouring videos and photographs taken on the night of the storm by locals, as well as CCTV footage of the port, according to local reports. Italian outlet Palermo Today said coastguard officials have visited all of the homes and public places with surveillance cameras pointed out to sea in the area. The Prosecutor’s Office are also reviewing the actions and decisions made by the Bayesian’s Captain James Cutfield, 51, and Matthew Griffith, 22, who is understood to be the first officer, according to local newspaper Palermo Today.

It comes as rescue workers continue to search for the last missing person - Brit teen Hannah Lynch - on board the yacht. The vessel’s chef Recaldo Thomas was found dead in the water soon after the boat capsized on Monday. Four bodies were recovered by specialist divers on Wednesday, with a fifth brought into the harbour on Thursday.

They have been identified as British tech tycoon Mike Lynch, Mo.
