One story hinted at dementia. I'm not judging this situation at all. Nobody was there to witness what happened. It's truly a very sad story and a horrible situation for this family. Nothing good can come of it at all, but it might serve as a notice to other families to remove any guns from the household if a member of that household has dementia or other mental impairments. I hope they can get to the bottom of this and find peace somewhere down the road.
