Sicily found a body Friday, presumed to be the teenage daughter of UK tech tycoon Mike Lynch, who also perished.
The discovery, confirmed to AFP by the Italian coastguard, brings to seven the final death toll in the sinking of the «Bayesian», which went down off the Italian island before dawn on Monday.
The bodies of Lynch, a celebrated tech entrepreneur and investor, and four other passengers were found on Wednesday and Thursday, with his 18-year-old daughter Hannah the only one still missing.
Emergency services had found the body of another man, believed to be the yacht's chef, a few hours after it sank in a sudden storm.

It sank within minutes.
Italian authorities launched what they called a «delicate» search operation involving specialist divers, boats from several emergency services and helicopters.
