According to AA route planner from Witham it takes 26 minutes. From Chelmsford it takes 38 minutes.
It would take much less time from Witham if driven at high speed by an officer who knew the area well.
The telephone call was put through to Chelmsford from Witham, hence the reason why Jeremy was put on hold, as Witham wasn't manned that night.
What evidence is there for that? It seems to differ from Pc West's version of events. Pc West said he was able to contact Witham, and the first officers at the scene were based at Witham, weren't they?
I think if a second car was sent it was on the back of JB's first call.
Bonnett's log shows that a second car (CA05) was sent. JB made only one call to the police and one call to JM. He tried other calls without success.
I believe an audio/video called Timecode Sound Visuals actually records the police logs, giving an account of a 999 call by Nevill, lasting from 2,24 to 2.31 minutes,and zooms in to show the recorded logs.
Malcolm Bonnett's log of the call he received shows it as not being a 999 call, but a call from Pc West, who passed on what he had been told by Nevill. It is the wording of that log that suggests the information did come from Nevill. It refers to Sheila using the word "daughter".
That 2.24 was the start of the call in minutes, not the time of the morning. It's an audio tape-recording starting from zero to 14 minutes, and somewhere, there are 5 more of these tapes.
A call duration wouldn't be referenced by both 2.24 and 2.31; the duration would be known exactly.
