I have just come across this news

Briefly, the guy came home drunk, drank some more, picked a drunken fight with his wife, threatening to kill himself with a knife, breaking a window and finally hanging himself in the bedroom.
"She said his behaviour that night was "atypical" but she had seen it before."
And "After the hearing, Mrs Campbell said: "He was a lovely man and a wonderful husband."" 
I cringed at this.
It reminded me so much of some threads here. :(
Poor woman.
