Scipio you said the following
"The level of detail she provides as far as the various times he talked about wanting to kill his faily is also significant. It is hard to make up such level of detail without a lot of thought and planning to come up with such. The claims are all credible not amazingly crazy claims. Her account seems credible.
"
If he had planned the murders for so long and in such detail and she knew all about it then he can not have been the cunning planning murderer that we think he was, because:
Why would he tell his girlfriend - who could tell the police at any time? Or recorded his plans or threats?
Why would he use a sound moderator ( there was more than one in the house btw) When there was no need to - it was an old house with thick walls (and according to everyone it would only have taken him a few minutes to pick everyone off)
Why then after using the sound moderator would he put it in a box in the cupboard with a hair and blood on it.

Why would he admit to getting in and out of the house by the windows ( BTW he said there was no window that could be locked from the outside and the police never proved that there was)
Why bother with the phone call at all - the farmworkers would have found the bodies in the morning and there would have been no idea of T.O.D ( not that there was anyway

)
Why would he have appeared to be so cocky and sure of himself during the questioning in Sept? I think personally that because he knew he was innocent the thought the police were being totally stupid ( not a good attitude though , did him no favours)
Why in fact would he risk a lifetime of jail when he was due probably to inherit a large amount of money from an elderly relative?
So he was either very clever to think he had committed the perfect crime - or stupid to tell anyone at all.
If you read JM news of the world interview she states he never admitted he did it - which contradicts her statement about her feelings on the night of the murder.
Sorry I am not convinced about her testimony - she may have done it because the police convinced her he was guilty and with her "help" they could nail him . In other words she was doing her public duty , but I can not see he would have told her all his plans.IMO
