I assume there was a quite broad release clause in the paperwork - not uncommon for settlements. If the other party refrained from offering assurances it might be hard to make an argument they weren't acting in good faith. On the other hand, it shouldn't preclude a criminal investigation. I can only assume the evidence was too circumstantial or trail too stale to gain traction from investigators. This is a really disconcerting story for a population that tends to assume we're the good guys.
