Cruise ship allegedly left woman behind on island, and she was found dead

An 80-year-old Australian woman’s remains were found after a cruise ship allegedly left her behind on an island.

Her body was recovered on Sunday, according to ABC News Australia. The search for her was launched Saturday night after she was reported missing hours after the Coral Adventurer cruise ship visited Lizard Island, which is about 200 miles north of Cairns.

The unidentified woman had been on a group hiking tour of the island but did not return to the ship, which departed between 6 and 7 p.m.

“We heard the conversation on the radio. They were looking for someone, and the last known location was halfway up the hill,” South Pacific II fishing and charter boat owner Rob Siganto told the outlet.

“We knew that someone was missing, and then we saw the Coral Adventurer heading back to Lizard [Island] on our AIS tracker,” Traci Ayris, who is sailing in the area, said. She had been woken up by the sound of a helicopter during the search.
