Problem:In Mystic River, Sean and Whitey don't have a clue about the real killers of Katie until they finally listen to the 911 tape. Sean notices that the caller refers to the victim as a she, although he couldn't know that the victim is a girl since he saw only the car and the body was dumped in the park. This tells Sean that the caller probably knew more about the case - but how did they make the connection to Silent Ray and his friend Johnny? Not once in the movie do we see them being in contact with the police and they didn't give their names either...
Solution:
In Mystic River, How did listening to the 911 tape solve the case?
