I would be interested in knowing how she plans to make it look like you were killed by a mountain lion.
Face Book is a disease. I live in serious mnt lion country. Its very rare that you get to encounter one. they are very shy and very picky about what they hunt kill and eat. Once in a while we have problems with old cats or sick cats that can't hunt.But if you ever see one in the wild you should consider your self very lucky and enjoy the experience. I get them on my trail cams all the time. Some times they walk under my stand 15 or 20 min before I get there. I have never had a single problem with one.
