Woman shot at front door...

[Jim101]

A couple of nights ago a woman answered here door only to bet shot and killed, a very sad story. Now I hear there have been (2) more since then, does anyone know why this woman was shot? (Keller area, I beleive) And about the other two shootings?
A few of us have been talking and I seem to remember it's legal to display a gun as long as you are on your property, is that right?

Thanks,

Jim
