i too am unaware of what exactly happened but i know what did not happen.
as a child i learned the four basic rules for handling a gun.
it was drilled in to my head waaaaay before i was alowed to handle live ammo and a gun.
that is what did not happened!!!!!
when i was a child a gun was one of the tools we used to feed our familys.
of cource my papaw also had nice pretty guns that were look not touch but same as the tools in the toolbox that held the needs to keep our automobiles on the road they alone would not take care of the cars. KNOWLEDGE was a necessity!!!
im not sure what area of the country this happened but im sure it was in one of them areas where having a firearm is a gun not a tool!!!
