If Noahs death is accidental, then this would be the general scenario:
Noah was unsupervised, wandered outside and fell in the septic tank. COD would be drowning. In this case, the lungs would be full of water, waste, sludge from the tank. If it were obvious by the presence of septic tank water in his lungs, then the tox reports would not be so important, we wouldnt be waiting on them. Also, Ashleys denial of bond and the judges assertion that it was unthinkable that Ashley should be around ANY child at this point, tells us that there is more to this than an unsupervised child falling into a septic tank just because he was unsupervised. If that were the case, why would Ashley potentially be a danger to her Uncles 11 year old daughter? She is not responsible for that child, so whether or not Ashley would supervise this child is a moot point. Plus, this is an 11 year old, not a young child likely to wander off and fall into a septic tank.
This is what effectively rules out the chances of Noah falling into the tank accidentally as a result of being unsupervised:
1.COD would be drowning lungs filled with septic tank water, not just plain water, and easily determined at initial autopsy.
2.Ashleys denial of bond twice, with the Judges statement about her not being around any child. Unsupervised children have accidents all the time. They are not usually held without bond, even after appeal, pending toxicology results.
Lid ON or lid OFF, it doesnt even matter, the septic tank waters presence or absence in the lungs would tell if this were accidental. And, they would be able to determine, based upon the alveolar changes/damage in the lungs, whether the septic tank water was inhaled during the course of a drowning, or if it seeped in post mortem.
The only possible thing they could be waiting for on the tox report, if the autopsy showed that the act of drowning took place inside the septic tank, would be to determine if he had drugs in his system when he fell in.
If Noahs COD was determined to be drowning, but the water in his lungs that is responsible for the drowning itself was determined to be water from another location (pond, bathtub, etc.), then it is only possible that Noah drowned/was drowned elsewhere and then his body placed in the tank.
Again, it does not matter if the lid was on or off, bolted or not, covered in sod or not. They already know most of the story. We dont yet, but there is a lot one can surmise by what we do know.
