A mistress gone crazy? Excuse me while I go work on my shocked face. 
The only thing worse than dying in such a stupid manner is your family dealing w/you dying in such a stupid and EMBARRASSING manner. My only consolation is that his wife probably knew about all of this anyway.
I will never understand this Telenovela sh*t as long as I live.
I don't care how heartbroken/screwed over you think you are(and since McNair's having a wife and kids is public record-she don't even really have that excuse) you will get over that sh*t eventually.
Nobody gets over being dead.
Its a damn shame all round
