During the Ajira massacre, most -- if not all -- of the Ajira Flight 316 survivors who remained on Hydra Island after Ilana's team left died. After their deaths, someone dragged them into a pile some distance from their plane. Their bodies showed no obvious wounds or other signs of how they'd died.
Sawyer discovered the bodies a few days after the passengers' deaths, judging by their decomposition. Zoe originally claimed to be the last of the survivors but later admitted to working with Charles Widmore, whose submarine had arrived that day. Widmore denied responsibility for the deaths, but Sawyer did not believe him. ("Recon") It is still unknown who killed them, although the Lost Encyclopedia implicates that Widmore's team was responsible.
