I actually know someone this happened to. Dad came home and midway through changing got a call from his father in law and went to go help him, leaving his concealed carry weapon on the nightstand. Toddler son got a hold of it and killed himself. On the day before his slightly older sister’s birthday.

Kid was buried on the property, within sight of the front porch. Mom demanded that and then couldn’t handle being there so they moved in with her folks for the next couple of years, and their living room was practically a shrine to the kid.
