My Sheila scenario also has the burn marks inflicted on the night.Anyway cant you just accept how utterly improbable that JB made the marks Adam.Simply wasting time for no logical reason.Dont you ever let the teensie weensiest bit of doubt creep into your mind Adam.Along with the problem creeping up on the twins,carrying Sheila through to be willingly shot,the police destroying the night dress and other valuable evidence,no conclusive DNA in the sileccer ,and i suppose we better mention the NOTW deal which MAY discredit Julies testimony.Not even a smidgen of doubt Adam.You remind me of Lee j Cobb in the movie Twelve angry men ,he eventually folded when it was demonstrated to him,that you dont always mean what you say,and how it can be taken out of context.Still its maybe me who is the fool in this case ,clutching at straws wishing for a happy outcome.I just dont know.Time will tell,something that JB is running out of.
