Apparently the doctors and coroners are not necessarily agreeing with the family that he was tortured.
And the family requested that an autopsy will not be performed.
So, normally I'm a big fan of "Anyone who tortures Americans needs to be suitably punished at at least 100 to 1 ratio" but in this case, it's suitably murky.
I'm also of two minds. Granted, we should always seek overkill revenge for the mistreatment of any American citizen... But on the other hand, if someone is dumb enough to go to North Korea, they're going knowing they could be tortured, murdered, enslaved, whatever.
