Oddly, this IS something my family experienced. My Grandmother was pronounced dead, family & close friends were called (I was assigned to call my cousins). When my Dad arrived at the facility about 45 minutes later, HE noticed she was still breathing.
Obviously it was not a media spectacle...but my Dad was extremely angry with the nursing staff and let it be known. I had to call my cousins back (very odd phone call to say the least)...Grandma lived for a few more good months...and we never told her:)
Hope this has a similarly good outcome.
She has a right to be upset.
Nonetheless she is a filthy mouthed ugly skank. Grief does not excuse this kind of trashy behavior.
