This I might have been willing to accept but what of the 8.10 log "House now been thoroughly searched by firearms team. Now confirmed a further 3 bodies found. Five dead in total".
I find it difficult to reconcile the two.
I can cope with this. I can see a distinct time lag between events on the ground and what is being is relayed from HQIR. The entry you refer to states that the info is coming from the Duty Inspector at HQIR.
At 7.37 just as the Firearms Unit were entering the farm, it was relayed over the radio by CA07 that 1 dead male and 1 dead female were found. At 8.09, CA07 reported all 5 bodies found dead.
With HQIR listening in, and just 1 minute later, I can certain see how they would assume '3 more bodies found'.
There seems to be a fairly distinct radio silence from inside the house for about 30 minutes as they search the house. There was other radio chatter, but not (from what I recall) anything directly from inside the house. So this leaves a lot of time when the facts were not yet updated to HQIR.
Whilst I am not saying this IS the definitive series of events, it is not beyond belief that just prior to entering the house, they have two sightings of the same body, one identified as male, and one as female, appearing to be dead. The logs suggest they heard a noise (possibly the dog moving?), and enter house forcefully. The log now reflects 2 dead bodies found - and is being relayed to multiple other parties all whilst the actual Firearms team are inside the premises discovering only 1 body...
By the time the house is fully checked and 5 dead bodies counted, the time lag makes it seem like 2 bodies + 3 bodies, rather than 1 + 4.
