Rivlin QC told the jury:
"The prosecution said Miss Mugford would have had to have had a convoluted mind to have made all this up. We say that she has."That Matthew (Mac-Donald) story is not only wrong in itself, but contains in it a number of details which can be proved to be untrue and which she can only have got from the police or Ann Eaton"
Why was he allowed to tell this to the Jury? here's why
Jeremy's "confession" Below is what Julie claims Jeremy confessed to her. This statement is false for two reasons. Jeremy's alleged confession of the crime as told by Julie Mugford does not correspond or coincide with the actual crime scene itself, as we all know Shelia was found on the floor not on the bed, the bible next to her also on the floor not on her chest. Had Jeremy committed the murders and given a detailed confession as Julie claims then Julies statements would corroborate the crime scene and they don't!

The second reason Julies statement is false is because her description of Jeremy's alleged confession is exactly the same as Ann Eaton and RWB's impression of events as seen in Ann Eatons notes and RWB's diary written in August. See below
Ann Eaton's note's second line down
"Shelia on bed bible on chest"
RWB's Diary

So not only can we establish that Julies claims are false we can now narrow down were she actually got that information from. Either Police or Ann Eaton as Rivlin rightly told the jury.
More disturbing correlationsWindows and the Bike In August RWB speculates that Jeremy used a bike then also in august RWB and AE speculate how Jeremy would enter the building


Then come September the 8th Julie reveals how Jeremy "confessed" to her his method of travel and entry, exactly how RWB and AE predicted!
The Wet suitOn the 28th of August Robert Boutflour speculates that Jeremy used a wet suit in the murders

This then appears in Julie Mugford's diary along with the bicycle
The £2000.00 payment 2nd of September RWB claims Jeremy lent a friend £2000

Julie then claims that Jeremy paid Macdonald £2000

The Fingerprints and the gun magazineIn August Robert Boutflour speculates that Jeremy got Shelia to load the bullets into the magazine to get her fingerprints on them.

Then come September lo and behold Julie claims this is exactly what Jeremy had confessed to her.

This is why Julies statements are completely false, Her statements have direct parallels with Ann Eaton notes and RWBs diary both of which deviate from the facts of the crime scene and contradict other factual aspects surrounding the case. Therefore Jeremy did not and could not have confessed or told her anything in her statements, it is impossible!
