This is an old thread but I felt that what I am about to post is relevant.
Some people think that blood only flows for a short while after death and then only if a body has been wounded. Others have pointed out that blood pooled in Sheila's mouth and throat and while some had congealed most had not so disturbing the body caused the blood to trickle out.
I work with farm animals and lose some occasionally to all sorts of ailments. More often than not I find that blood can start running from the head area even after the animal has been dead for over 24 hours and even though the animal has never been moved. So little wonder that Sheila appeared to bleed several hours after she was fatality shot.
Tesko's claim that Sheila was shot by police thus why she was still bleeding when the first photos were taken is therefore consigned to the dustbin.
