An investigation into the Sicily yacht deaths is considering multiple options including manslaughter, officials have said.

In a press conference prosecutors said they are in the early stages of the investigation and stressed they are not investigation anyone specific at the moment.

Italian authorities confirmed the final missingbody found was that of 18-year-old Hannah Lynch, daughter of British tech entrepreneur Mike Lynch.

Officials also said the yacht, called the Bayesian, likely sank due to a down burst - a localised powerful wind that descends from a thunderstorm.
