That is true! However, here is another possible theory. Suppose he was poisoned. (he has already been embalmned so we'll never know). He is dying, knowing that he has probably been poisoned. With his last effort, he places the pillow over his head to signal that a murder had occurred. He knows it could easily be determined that he wasn't asphyxiated, yet what other way to send a message beyond the grave? The older we get, the more cynical in my experience. :{)
Though one would think he could just make a phone call or a text.
Columbo solved a mystery that way, the victim arranged venetian blinds to identify his killer.
Obviously, his killer was named or nicknamed pillow...or feather...or foam...or pillow case...
I see your point.
But I still haven’t seen any clarification about the location of the pillow.
“Over” his head could mean above his head between his head and the headboard.
I think he went to bed and just died.
But we can put nothing past the Evil ones.
The people who found him said that his hands were neatly folded on top of the sheets. If moving the pillow was his last effort, his hands would be next to the pillow. Also why would he suddenly realize that he has been poisoned when he is already lying serenely in bed, and if so, why would he keep lying in this position?
Some people sometimes like to sleep with a pillow over their head. Often hotel beds have a lot of extra pillows. Evidently his large family does not think that the circumstances are suspicious.
