One thing that bothers me about Julie Mugford's story is this:
She went to the police in September and told them Jeremy had told her that he paid Matthew MacDonald to commit the murders.
Why would she say that if Jeremy did not tell her that? If she wanted to lie and drop Jeremy in it, why would she say that Matthew MacDonad did it? Did she have some kind of grudge against Matthew MacDonald as well?
Exactly!
Why mention MacDonald if she wanted to get back at Bamber? Unless she believed it to be true, for whatever reason.
Also, when she went to the police - and her friend Susan - the News of the World was nowhere in sight. And couldn't be guaranteed whatsover in those days, especially as she was talking about MacDonald as the killer.
If I had been her friend I would have said you have to tell. perhaps she really loved him and found if difficult (?!) but her friend kept saying this is murder. One day it might be you.
Actually, had I been her friend, I would have told the police immediately, unless Bamber had a reputation as a bit of a fantasist and braggard. Did he?
