She may have been carried or moved by Jeremy (if he's the killer - have to keep saying that).
I agree.
But if police had found her head propped up though that would be even more damning and an even more significant indicator she had been moved by the killer. If I were biased against Jeremy I would be insisting that Woodcock was right, her head was propped up and thus that proved after her death when the blood on her face dried or was near dry then the the killer propped her head up against the nightstand. But I am not baised and accept that Woodcock was simply mistaken.
Those who support Jeremy don't seem to appreciate that if her head when found by police had been propped up as Woodcock described then this is highly damaging to Jeremy. The police doctoring that is being alleged would have helped him. But there is no evidence that supports Woodcock it suggests he just was mistaken.
