I am sorry, because
he was found not guilty does not mean that he is innocent of the charges (dubious past). imo
It is not a fact that he has no dubious past. Just that the charges were difficult to prove after 30+ years, as happens in too many historical cases, so he walked (again imo).
And because the seven Vic charges were then dropped does not mean he committed no offences there - those charges were contingent on tendency evidence from the NSW case.
Whether or not he is involved in William's disappearance .... I don't believe those little girls made the story up, or that they were mistaken who harmed them, or that their mother had it out for him and they all just went along with it, or whatever ineffective reason that I have heard before.
The only ineffective reason that I can partially understand (for the headspace in 1987) is that he wasn't prosecuted then because of the young ages of the girls. That they were 'protecting' the girls, that they thought they would just 'forget', that a trial would harm them further.
The court heard some witnesses had died but that was not unusual in historical cases.
