I agree with Omorlo, but neither does it prove that he did it.
Kethi should make her father's autopsy public
Yes. It does not prove he did it either. Which is why the IG blew his first major test.
Incidentally do these people know why decent countries employ spokesmen to pronounce the unspeakable to the public? Here is Arachi ruining himself forever. He has linked his name to Fidel's death for all the future. 50 Years from now vooke's grandchild will be writing a thesis on the Fidel Odinga Assassination (or Death) questioning the role of the IG. Some stigmas are totally avoidable.
On Kethi and autopsy: Assassins who use poison have one thing in common with conmen who make you hand over company cash to them to double. They design it such that you have a greater interest in covering it up. If it comes out you face total embarrassment and lifelong shame.
