I am way behind at the moment, I think on page 6, sorry if you have covered this.
Has it been ascertained that GBC made the facetime call from his Brookfield home? could he have been at the elsewhere? Was NBC necessarily at home when he received it? could HE have been at the roundabout when he received the facetime call?
One of the reasons that QPS might be looking at the roundabout is if they could place one of the phones there that night?
Im pretty bad with the whole phone pinging and signals and IP addresses etc, but is it possible to pinpoint the location that accurately? after the event?

First - Facetime calls can only be made via WiFi connections, at least here in Australia at the moment. The only WiFi anywhere near that roundabout - and I don't know if it would be switched on at that hour of the night - would be the BCC Library. But you'd need to be closer - eg in the carpark almost underneath the library which is above the carpark.
The question about determining if fluids are pre- or post-mortem is tricky. Blood can leak in the immediate post-mortem period (few minutes) and retain certain characteristics for a short time. But after that, it can't be "aged" with any degree of certainty. So forensics wouldn't be able to tell if the bleeding was pre or post mortem, or how long the blood stain had been there unless there was something overlying or underneath the bloodstain that they COULD put a time on.
Other bodily fluids are similar - if it was vomitus, mucus from the mouth or nose (or elsewhere), etc - as far as I know there are no specific characteristics that would determine (a) pre or post mortem, or (b) how long it had been there. That has long been one of forensic science's problems - the inability to "date" or "age" blood and other fluids.
Bathwater in the lungs would be different, and of course would suggest a cause of death. However, when trying to drown someone by holding their head under water, the first and major thing that usually happens is that they get laryngeal spasm. Their vocal cords shut tight to protect the airway, and in many cases, they actually die of asphyxiation due to that, then as they die, and the vocal cords relax, they then take water into the lungs. Same difference in the end though. And of course, bathwater would be totally different from Kholo Creek water - just in case there was thought of her being alive when put into the creek.
I would imagine she was already dead when taken out to Kholo and that she wasn't put into water. I think the water rose and "took" her after that huge amount of rain we had.
As for being killed in the Brookfield house - there would be other evidence for that, I imagine. Which they haven't yet told us. The blood in the back of the car - if it was indeed Allison's and was related to the murder (as opposed to being pre-existing) - would suggest that EITHER the injury was caused in the back of the car, OR that one would expect to find more blood at the site of the murder. And maybe that's what they found in the house. Or - what they have been looking for on multiple visits and haven't yet found???
