There have been persistent rumors over the years that Kim Jon Un is dead. I'm not sure how much of this is just psyops against North Korea to cause internal problems for the country, or if Kim is really unhealthy (which he appears to be). I think its still uncertain whether Kim is dead at this moment, but I wouldn't be surprised if he dies and his sister takes control at some point in the future.

edit..

Looks like he also toured a facility on September 5th, but I guess it could always be a body-double. Who knows exactly how a clandestine transfer of dictatorial power might go down.
