The siblings might have been innocent of killing her parents but its clear that they killed other people, in fact if their father didn't kill the parents they probably would have only to protect themselves like with miwa and pretty much all of them tried to kill her just to that end. The judge was a serial killer, the okawa? killed 2 elderly for a piece of land, the producer and actress also killed miwa and didn't seem to sorry for that. So I would never call them innocent...
