Are there guns in your house? Is she a good shot? If “yes” remember that it will be difficult to frame it as a gun accident if you are shot in the back 3-4 times.
I recall a French incident wherein a supporter of a nuclear waste dump was found “mysteriously” shot in his house. (treehuggers had threatened him repeatedly). Shot twice in the heart. Uhh, yeah, right. That is how I’d do it. Sure.
BOL!
I would not want any female members of our families shooting at me!
