My 89-year old father is an absolute mess. He needs to be in a nursing home but won't go. I had to give him a shower the other day after a nurse told me he was filthy and needed one. On the whole I would rather give my 20-pound cat Sumo a bath than my dad. There are parts of his decrepit and shriveled anatomy that I have now seen and can't unsee.
I wish he would go peacefully in his sleep tonight.
So, I am sympathetic to the old guy's story, but still have some questions. The wife is surely on medicare at her age, and while it doesn't pay for everything, it pays for at least 2/3 of the costs of pretty much any care. Also, there are kids mentioned, are they not in a position to help pay? If my Dad needed help with medication, my brother and I would certainly pay, no matter the cost. What about a church? Dad's church would help out if he needed it.
What about things like reverse mortgages, Medicaid (rules vary by state, but she may have qualified). Heck, he could have sold his gun that he shot her with and probably kept her in meds for another month or two.
It's possible the story is 100% true, but it wouldn't shock me at all if there was more to it.
