Prosecutors in Italy said Saturday they have opened an investigation into culpable shipwreck and multiple manslaughter after a superyacht capsized during a storm off the coast of Sicily early Monday, killing seven people on board. They included British tech magnate Mike Lynch and his daughter, and the ship's Canadian chef . Termini Imerese prosecutor Ambrogio Cartosio confirmed the investigation has been launched, but said no suspect is currently identified.

"We are only in the initial phase of the investigation. We can't exclude any sort of development at present," he told reporters at a news conference. Cartosio said his team will carefully consider each possible element of responsibility, including those of the ship's captain, the crew, individuals in charge of supervision, the ship-builder and others.

"For me, it is probable that offences were committed, that it could be a case of manslaughter, but we can only establish that if you give us the time to investigate," he said. The main question investigators are focusing on is how the Bayesian — a boat deemed "unsinkable" by its manufacturer, Italian shipyard Perini Navi — sank while a nearby sailboat remained largely unscathed.
