Interesting how this got completely left out of the news reports. But it makes perfect sense. Why would a “mass murder” in a target rich environment only kill 2?
Simple answer: he was stopped by a good guy with a gun.
The good guy showed excellent discernment, and ended up not having to shoot the murderer. The murderer took that confrontation as a prompt to end his killing spree himself.
Congratulaions to the conceled carry. He did it just right. I commend him, but wish he had had a clear shot.
