SOCO Neil Davison's statement to COLP states that on 7th Aug he was contacted by Linda in 'Control' by phone, at 7.30 (?) and requested to deal with a murder and a suicide. It later goes on to express that by murder and suicide, he thought it could either mean one or two bodies, adding some ambiguity to the meaning of the information he recieved when contacted.
If you look at the logs, Linda's information matches the log entries, in so far as there having been two bodies found on entry. However, a reverse argument might be that there was confusion due to the body seen through the window scenario and that Linda was merely reacting as a result of that confusion.
Some months ago on Jeremy Bamber's blog, it was stated that the police who entered the farmhouse all wore open microphones. I am not sure what this means exactly or what the implications might be of using this system of communication.
