Maybe employ the bag in case one doesnt do what its intended or maybe employ the bag to make it appear as suicide or maybe if its a dark bag or colored one so they dont have to see her face while theyre doing it which ive read often people put blankets and stuff on peoples faces whom they know after theyve passed so they domt feel as bad? I think i read something about casey anthony doing something like this but i may be incorrectUgh, Stryker, don't read this post; I hate typing it. But I can't understand. Is it more effective to take someone's life by fighting to get a plastic bag over their head and holding it there, vs mannual strangulation?? Or would it be strangulation at the same time, in which case why bother with the bag? Perhaps if the victim were first rendered unconscious. I am struggling with this new information. Dear Cheryl. What horror you experienced. I am so sorry.
