Oh my god. I am so sorry for your loss. I grieve for your family but I do ask one thing. Please please I beg of you, make sure your daughter does not feel in any way responsible for this tragedy. I'm not going to lie to you, this is going to haunt her for a long time so be prepared. Just like your daughter my aunt was on watch many many years ago when her mother died. She did not have the support that your daughter has right now. To this day she still has issues and is haunted by what happened. I hope that your daughter does not do the same. So sorry for your loss.
