Trouble Finding Details On Great Uncle's Death
I (35F) am trying to do some digging into my family's mental health history.
My Great Uncle passed away at the age of 31 while in some sort of mental health care facility in May, 1974, in Bell, Los Angeles, California (he was originally from RURAL Idaho).
The diagnosis I grew up hearing whenever he was mentioned (this side of the family has an...old fashioned approach towards talking about this sort of thing) was "schizophrenia", but when I heard later that he was committed after saying he thought he was a radio tower... well. That definitely doesn't match up with current understandings of that diagnosis.
There's nothing in his obit (I think it said he passed "after a long illness"), I can't find the name of the hospital, and the only surviving member of that side of the family is my Great Uncle's brother-in-law - my grandfather, who is almost 90 years old, with a fading memory.
I also can't find any records of an autopsy, and there's this old whisper that he may have died at the hands of the orderlies.
Any ideas on finding more information?
((Forgive me, I'm used to Reddit being fairly anon, and given there's only one surviving branch of this uncle's family, mine, that I'm aware of, I'm not sure about giving his name and other details))
