Hi. I am looking for an old movie, probably Hollywood. Watched it around 1990’s. The movie started with a car accident, a father and his daughter died at the scene, leaving the youngest daughter alive. She was taken to hospital and due to the trauma, she lost her voice. A young attorney believes she knows the murderer. He persuaded her to tell him how the murderer looks like. She didn’t tell. Finally, she spoke out the truth at the court. The murderer is her mother. Her mother is having an affair and tried to killed everyone. She told the judge her mom is the killer.
