It's especially bizarre considering that if I was going to smother a person to death with a pillow, I would either A: remove the pillow from the face so it didn't look like a murder or B: turn the body face down and put the pillow under his face so it didn't look like a murder.
Now in most cases petechial hemorrhaging would betray asphyxiation, but in this case even with known asphyxiation his state of health could lead to a ruling of natural causes. If he was in fact murdered, then leaving the pillow on top of the face is frankly the last thing I would expect.
Only time I would expect a pillow smothering murder to leave the pillow on top of the victim's face, is if the victim was a loved one of the murderer and they wanted to cover the face out of guilt/remorse. Like a husband or a wife or a parent who thinks they are doing the right thing but cannot bear to look at their victim's face.
Nothing whatsoever about that makes sense, and I half suspect it's someone having a laugh at the expense of conspiracy folks, trying to make conservatives look dumb.
