I would like to address this myth in a seperate thread. I see it as an important piece of the puzzle. Whenever "nons" are asked where Sheila was while the rest of the family was being killed, the answer is almost always: she slept through it all, then Jeremy came to her room and "led her" to their parents´ bedroom and killed her. During the whole thing, Sheila was cooperative and passive.
First of all, I do not believe Sheila COULD have slept through the killings, it would have been noisy, dogs barking, screaming, shots, commotion; but let us say she did.
WHY would Jeremy, who allegedly had preplanned the whole thing and wanted it to appear that Sheila committed suicide after having killed the rest of her family, choose to lead her to a room full of blood and the corpse of her dead mother? Wouldn´t that be sure to upset Sheila? Nons, why? How did he manage to, in the first place, to maintain her cooperation in her own killing, not to mention IN that particular, blood-filled room with her dead mother in it?
Does this make sense to you?
