Though this could have been prevented, it was not.
And it happened, therefore the situation has become tragic. Though this situation doesn't sound 100% alright, it is possible.
I add my huge condolences to the family of this woman, as well as the friends and people who cared about her. Everyone makes mistakes, and hers didn't end up well.
I guess I almost put myself in this situation, if one of my snakes that large killed me in the future, how my family would feel. It's a very painful thought.
