Are people in that area familiar with wild hogs? Did she know how to react?
I’ve never seen a wild hog in person. Nor a wild pack. What do you do when that happens? Assuming I’m without my firearm.
My guess is that she tripped and hit her head. Then the hogs came later...scavenging.
And the only reaction a person can have with an attacking wild hog is to have a gun or get up a tree. Not all 59 year old women can do either well.
