We had a similar thing happen a few years ago. One of our agents who came over from another agency was having an argument with his wife about something stupid....what was for dinner, I believe....and he shot himself in the head, in front of his wife and baby boy. Nobody really knows what prompted him to do that, rumors abound that he was trying to "get her attention" to prove how serious he was, and accidently pressed the trigger since we had just switched from the double action SIG P229. It's certainly not an action that I would have attributed to his personality, though we do know he had some stuff going on at home. I mean, we all have "stuff" going on at home, too...so...
In the end, it amounted to a tragedy. Sometimes it's best to just accept that, and make come to terms with the fact that shit just doesn't make sense sometimes and even rational people we respect can "lose it".
