Exactly, ABeta. This poor lady! Regardless of how she met her end, she did, in a sudden and very tragic way.
She left behind a husband, two young sons, a sister, a mother.
Oh, her poor mother, too! My mother is just a few years younger than her mother, and sadly, some of her friends' daughters have already passed away (well, two, from cancer) Their mothers' grief knows no bounds. It is a terrible, awful thing to lose your child no matter what their age.
Surely it's not the time to be speculating on any mistake she could possibly have made that contributed to her demise, which from what I can see are none.
