A yacht belonging to UK tech entrepreneur Mike Lynch, who was recently acquitted in a major fraud trial in the US, capsized off the coast of Sicily due to unexpected weather.
15 people were rescued, but five have been found dead, including Lynch and his 18-year-old daughter Hannah. Four remain missing, including Lynch's American lawyer and his wife, and a British banker and his wife.
Rescue efforts have been hampered by dark conditions and a lack of official identification of the bodies.
The yacht was a celebration of Lynch's acquittal and was carrying 12 passengers and 10 crew.
Everything that was done leading up to the capsizing reveals a long summation of errors.
