Ok, a scary movie when a man who thought to have killed a police officer's daughter is captured and tortured by police officers and ends up dying in the hospital because of his injuries and his ghost comes back and starts killing the officers. The officers think they killed him wrongfully but come to find out he actually did kill the officer's daughter. The ghost of the officer's daughter later comes back and tells them how to stop him.

This?
