I sometimes put a pillow over my head. I travel a lot and sometimes there is light coming from windows or whatever that I don’t like. People who get migraines do. But let me ask you a question...if someone was going to kill him by suffocating him and make it look like natural causes... WHY WOULD THEY LEAVE THE PILLOW ON HIS HEAD? If you come up with a logical answer for that, I will donate $20 bucks to FR.
The pillow could have been left as a sign of what little fear the perpetrators had of ever being caught. Furthermore, it would serve as a warning to any other person thinking of doing something rash.
Probable? I don’t know. Possible? I think we all know that.
