I think they can probably stop looking -
Some suggest he finally ended up in a jewish cemetery
in Berlin... Jews don't permit their graves being
dug up, yet express serious insult they feel about
such a person being in such a resting place.
I am inclined to say Müller would have had a crafty
escape plan that succeeded in throwing investigators
off his trail..
Many less capable high rank nazis
than Müller were able to elude capture.
