That is a mystery. Yet, it is possible that if something happened to Connie, the dog may have laid next to her and is either still with her if she is alive, or deceased as well. Some dogs won't leave their owners for even food and water. I do hope if that is the case, that she had a medical emergency, that the dog was by her side and she wasn't alone. I don't know why, but I am hyper sensitive to people dying alone and afraid- it just breaks my heart. She is 76 years old, and even though she appeared in great shape for her age, it is very possible, as Grace mentioned, that she had a medical emergency and is probably no longer with us. I'd rather have that I suppose than to have anything sinister happen to her, but it's such a lonely way to leave this world.
