I don't know why the campaign team go on about the polygraph so much because there is a much more valid and convincing report that claims to fully exonerate Jeremy. Doctor Marco Meloni and Professor Cavalli testimony that based on the crime scene photos and one Police officers description of Shelia's blood they claim the earliest she could have died is 7AM. So according to them Shelia Died when Jeremy was outside with the police. I repeat according to them
So if there is one thing remotely convincing that could exonerate Jeremy it would be this. Not the Polygraph
