That's so sad! What's the saddest story you've ever heard?

I once knew a man who went for a walk. While on a walk his wife took a pistol and shot herself in the chest twice. She had recently been to inpatient psychotherapy and was not doing well at all. He thought he had the guns locked up securely but she somehow found the key. When he came back from his walk he found her on the floor of the kitchen and screamed her name. He then screamed how could you? She gained enough consciousness to tell him she was sorry but could not go on living that way and then died. He grieved himself tremendously over the next year until on the anniversary of her death he shot himself twice in the chest on the same spot in their kitchen. True story. They were both in their 80s and like family to me.
