My take, mom was on psychotic meds and they were not the right meds, death by psychotropic drugs.

My take is that the mom was psychotic and unmedicated.

I knew somebody who survived a homicidal paranoid schizophrenic mother who wanted (and tried) to kill her, and if modern medication had existed in those days, her life and that of her mother would have been entirely different- and a lot happier.
