The Unstated Alibi

what happens

An old woman is pushed down the stone steps of a temple in Beika City. She claims she was pushed by a young woman, but there is no other information about the case. In the crowd is a man staring at the old woman. The police speak with him, but he suspiciously claims he doesn't know anything about the incident and leaves. He seems to have witnessed what happened, but for some reason he can't speak about it...
