Was he the hoarder or was it the wife?
If he had been the hoarder, presumably the wife would have cleaned up after a while. Chances are that she was the hoarder and the condition of the home drove him to despair and suicide. My two cents’ worth, anyway.
“Was he the hoarder or was it the wife?”
You can’t have two people living together in those conditions without both of them contributing to the issue.
She had to be the hoarder or she would have emptied the house after he was gone a short time. No one would willingly live in that. Probably why he offer himself.
