Divers have recovered the remains of the last person who was missing when the Superyacht Bayesian sank early Monday off the coast of Sicily, the head of the island’s civil protection agency, Salvo Cocina, told CBS News on Friday. The body was brought ashore, but has not yet been officially identified.

It is probably the British Hannah Lynch Tech magnate Mike LynchAccording to Italian media, she is the singer’s 18-year-old daughter.

Mike Lynch’s body was accessed on Thursday from inside the sunken ship, which lay on the seabed at a depth of over 50 meters, at a 90-degree angle, making rescue efforts complicated and dangerous.

Shortly after the 184-foot luxury sailing yacht sank, the body of the ship’s cook was recovered from the water near the wreck. Divers managed to recover four more bodies by the Bayesian on Wednesday, including two Americans.

With the recovery of the body on Friday, the total number of victims rises to seven, including all the victims on the boat belonging to Mike Lynch’s wife, Angela Bacares.

Fifteen people survived the sinking, including Bacares. The survivors were found on a life raft by the captain of a boat anchored nearby.

Prosecutors are interviewing survivors and witnesses to determine what might have caused the luxury superyacht, equipped with state-of-the-art safety equipment, to sink during a storm that witnesses say occurred within minutes.
