This bear may have been trapped, tagged , and DNA tested in the past. They have records like this on many of the bears in this area.
Hmm.. Puzzling.. So they had info on this bear, medical info, and very probably knew she was aggressive.
So....here comes a multi-million dollar lawsuit by the family of the deceased. Issue: Mr Park Ranger, you obviously knew this was a deadly bear and you did nothing about it. Ruling: For the plaintiff; reward the family a few million dollars.
