Guilt my eye.If JM had been as truthful and honest as she'd professed to have been,and knowing JB as she did,she'd have spoken her thoughts at trial by saying that he hadn't murdered anyone. JM knew in her heart that it wasn't Jeremy and was dragged along by others who'd had a vested interest.
Nobody can tell me that JM was the type to continue her relationship with a" murderer" of a whole family,including two little boys,whose bodies she'd viewed at the mortuary. No way !! Nobody is THAT much in love knowing that. Also to accept money for holidays after the event and help with moving doesn't gel with the fact that she " knew him as a murderer ".
