Ramasarma Venkata Parnandi

Taking and suspense in the movie is very interesting but there is no valid logic for the murders,done by a ghost, of innocent people who took uturn on the bridge by removing diveder blocks. As per Hindu mythology there is a trust that God or Ghost knows everything that happened, happens too. In such case how a ghost doesn't know the person who was responsible for its and it's daughter's death and continues to kill as many as she suspect?
