My wild theory was that there was some highly valuable cargo onboard. One or both of the pilots were in on the plot to steal it. They diverted the plane, flew to maximum altitude and depressurized the plane to kill the passengers, then executed a water landing someplace remotely in the Indian ocean. They rendezvoused with a boat, unloaded the cargo, and the plane sunk basically intact (so no debris). Though your theory is also interesting - I wonder if a successful water landing could be executed by remote control?
