The six people who died during that so-called "riot." Per a sermon was listening to,

the other night.  Two of the individuals evidently, should have stayed away from all that - two men, in their early 50s, either had fatal heart-attacks the same day, or on the following.   i seem to recall, a third person who died shortly after... something about a health condition.  Whether or not, the preacher heard the details right, even if the accounts of these three individual's is true...story won't see the news-room foot-lights anytime soon.  To repeat, i do not know the details.  But one thing i do know - the news media is about as trustworthy as a shifty-eyed neighbor/co-worker/family member wanting to sell you something.

Another thing i know is, it was very cold on January 6th; we all know, that people with heart conditions are warned about exerting themselves in cold weather.  Granted, nobody was shoveling snow...just climbing walls and such.
