Seems the 4 issues rejected so far are -
The 6.09am 999 call.
Nevill's call to the police.
Two silencers.
Disturbance at the crime scene.
----------
Sheila calling 999 & not saying anything is a non starter. Ditto Nevill calling Chelmsford Police.
Two silencers I do not understand
Disturbance at the crime scene was dismissed in 2002.
