There are numerous signs something is amiss ... Kim's personal jet has sat on a runway for way longer than normal. His train remains at a station near a resort where he and his family typically stay, but there has been no recent sign of the dictator.
Kim has not been seen -- at least publicly -- since April 11. The South Korean official who says Kim is alive says "No suspicious movements have so far been detected."
If Kim is dead, his sister would probably take the reigns until his kids grow up.
