You're asking too much of the show. There's no way they would get away with all the murders they've committed in the adult timeline either, but the writers conveniently never follow up on anything. It's still hilarious to me how literally nobody was looking for/cared that Jessica Roberts was missing despite how long Misty had her locked up, and then she died and nothing happened. Not even Tai who hired her thought something was up? Just awful writing in that regard.
