When Dutch prosecutors discovered that one of the passengers' bodies from Malaysia Airlines Flight 17 was wearing an oxygen mask, they began speculating "about how much those on board knew about their fate," The Associated Press reports.
Wim de Bruin, a spokesperson for the Dutch prosecution, told AP the Australian passenger was found wearing the mask around his neck, not on his face. De Bruin added that prosecutors don't know "how or when the mask got around the victim's neck."
The plane crashed in eastern Ukraine on July 17, during a flight from Amsterdam to Kuala Lumpur. All 298 of its passengers were killed in the crash, which Dutch prosecutors have said was due to strikes by "high-energy objects from outside the aircraft."
