I never said it was impossible. I do not believe it was Sheila. I believe there was more than 1 killer. I do not think Jeremy did it alone or maybe at all. I think there is some persons who has been walking free for 30 years who played a major role in the murders. No one will ever come forward as they will get life. I think it was hired killers. like all of us on here no one knows the truth as we were not there. Can we really ever know the truth?
