We know Julie made up the McDonald story since she let slip that she didn't know if McDonald had ever visited the farm despite claiming to have believed he was Jeremy's hitman who killed the family at the farm.
"I have been asked what I know about Matthew. I have only met him a couple of times, always at Head Street, Goldhanger. He made me feel very nervous although I do not know why. I am aware that Jeremy met him through a previous relationship, in fact whilst he was living with Sue FORD in Colchester. I do not know if Matthew has ever been to White House Farm".
"I have been asked why I did not make known to any other person, particularly to the authorities the contents of the conversations between myself and Jeremy BAMBER for 20 days, namely the 27th August 1985 when I then told Susan BATTERSBY. In answer to this I can say that in my subconscious I believed what Jeremy had said was true and I would qualify this by stating that I believed Jeremy when he said he had hired Mathew to kill the family".
