With what had been reported earlier about what neighbours had seen and heard, I had thought there might be a possibility mum wasn't involved in the immediate events. 4:45am man seen by the river, 5:30 arguing heard, including a child's voice (could have been mum being made aware Logan was missing and the panic started), with her shouting about the back door being open a while later. But now that they've charged her with murder, either that isn't the case, OR perhaps that is how it happened that morning, but the 14 year old, having been charged with murder himself, is now reporting of physical abuse the mother inflicted on Logan which could have caused him previous injuries with long term (maybe even 48 hours) consequences which may have contributed to his death. I think the more likely scenario is that she was wholly involved that morning, otherwise it would have been very difficult to obtain the evidence to charge with PCOJ so quickly. However, in the Wayne Couzens case, his wife was arrested on suspicion of PCOJ, but I didn't see anything at all in the evidence presented that indicated the grounds on which that arrest was made. I think in the case of a failure to act, as in not getting emergency help after the fact, manslaughter would have been a more likely charge, although there is a case for it to be murder in that instance as she's the person with primary responsibility for his care. All just MOO and my own musings.
