hhhmmm the dead mother was a gun collector ? the son had a history of emotional issues? why would anyone have a house full of guns if you have a disturbed.troubled person living with you? Wonder if she had them locked up?
I have young children and I have guns,,,a 45, Glock, a few shot guns and such, and they are all locked up and the safe has a bio-metric lock.... not even my wife can access them
