Sad situation. Anna is one messed up lady, but this is a tragic situation.
Well, she hired him. . .so it is her money and his word. Suspect we will not get the whole truth here of just what happened.
But for the overview. . .no autopsy needed. I just hope that her son's death moves ANS to a more exemplary lifestyle and one that is deserving of her newly arrived daughter.
Personally do not care a whit about her; other than at the level of being a 'human being' and that she is a Mother with a child to whom she should feel obligated to love and protect.
so.. doctors prescribed him the medication? was it the same doctor that prescribed all of the meds? IF NOT, did the other doctor/doctors know of the other meds that he was on/taking?
