Very sad as nobody deserves such fate. As nothing was missing in the room, no signs of break in, of a fight, obivously no other suspicious DNA hoping they did they check...if so, then unfortunately the idea of suicide could make sense. CCTV obviously did not give any leads which may explain the new explanaition. They won't try to hush up as usually the Consulate of at least all civilised european countries, sends an consular official to enquire on the progress of the investigation. (often such a consulate "official" has a law enforcement or legal backgrownd in the home country).
