The aircraft was at 36,000 feet in the hold. Perhaps the pilot put the plane in the hold so he could subdue remaining crew and pax or mess with something outside of the cockpit?
At that altitude anyone without oxygen would be passed out or dead (higher than Mt Everest).
In another tragedy, A Greek 737 had a pressurization issue (crew failed to communicate because one was Ukrainian and the other was Greek) and it killed everyone except a flight attendant. The FA could not get the plane off autopilot to descend. The aircraft flew to the last waypoint in the FMS and entered a hold and continued holding until it ran out of fuel and crashed.
Perhaps that was what happened with this hold except it eventually left the hold for some reason and continued until it ran out of fuel and descended into the ocean?
