Seems to me, that there are people, who are examining this case, from entirely different perspectives!
There are those who whole heartedly believe that Jeremy Bamber, had killed the five members of his family, and that he it was who had staged his sister's death on the parents bedroom floor as a suicide, with the specific intention of portraying Sheila as the killer, and she having been responsible for her own death, by way of Suicide, where she had shot herself in the neck twice!
