Tragic, but neither story makes sense. There is more to this story for sure. 1. If the two owners got into a fight and shooting why wait until you are across town to call police?  And, say it was self defense? 2. How did an approximate  170lb young man wrestle a gun away from a 25 year military veteran who provides tactical classes? And, why would he wrestle it from him and run outside to call 911, why not hold him at gun point or .....?  And, when did Pisano get there, was it before or after the surveillance cameras were turned off. If before then that is almost an hour prior to opening which means all of them knew each other and were meeting. This is so sad but I will be following it and hope we do learn the truth.
