When I was a kid, a neighbor was shot in his garage. There were definitely two stories that went around the neighborhood. One said suicide and the other said “cleaning his gun.” One of those was repeated when kids were around. The other when they thought no one was listening.
Years back, I read was a very odd story about the Korean belief that falling asleep in a closed room with a running fan would result in death. This also seems to be a cover story for suicide.
It sounds like she had a lot of fun in your home. I try to remember things like that when I’m feeling a loss like this.
