Well, either it was Sheila making a 999 call or it was the operator making the link from the farm to the police at 6.09, how this can be proven one way or the other is beyond me? Not enough details at the moment!
Maybe the CT should investigate the 'phone engaged' at 5.47 log like Bubo says? Like finding out who wrote it and exactly what it means?
There are plenty of details!
Wednesday 7 August 1985 I was the Duty Sergeant in the Force
Information Roon at Police Headquarters, Chelmsford. At about 03.45 hours I became aware of the an incident in the
Tolleshunt D'Arcy area. At 03.56 I caused the Telecom Operator to check the line on a Maldon number 860209. This was done and I was told that the
telephone receiver was off its rest. At 05.55 I caused a second check to be made with the same result
accompanied by a report of a dog barking. At 06.09 hours this open line was linked up with our "999" call line
and was thereafter constantly monitored by Pc Millbank.
Inspector D Burrell.
I am not allowed to engage the Direct Energency Police line so I again checked into this Maldon number and then phoned the Police Headquarters and connected the two thus enabling the Police to listen to the line. I didn' listen to the line at all this time as I was engaged in making alarm calls end other British Telecon
Services. I went off duty at 8.00 ah. on the 7th August 1965 and at that stage the
Police were still monitoring the line.
I had no further involvement
since I had connected the two, I had no idea what had happened.
