FWIW I think it’s plausible that Aimee either wasn’t aware or was manipulated to thinking her father was innocent until he was found guilty. This man will be extremely manipulative and is no doubt convincing, he continued to plead innocence and forced a trial even though he knew there was overwhelming evidence against him.
I was friends once with a guy who later was convicted of awful assault against a young girl. No one who knew him had any idea, not a clue. After he was found guilty a few things, with hindsight, made some sense, but we could never have guessed before, you just don’t think those things about someone you believe to be a decent person.
GP need to take a long look at their safeguarding and this should be national news. But I’m not sure AC isn’t a victim here, it’s a likely awful childhood they’ve had.
