Yes. It was revealed she did. I don't remember for how long or if the anime even stated when exactly she knew that Mikami is the extra. But she decided not to tell anyone because she thought it was pointless; she didn't know that there was a solution and that the information of knowing who the dead one is is actually important to and is connected to the solution itself.
