Quincy, M.E. - Season 8 Episode 11 The Law Is a Fool

At the end of a school day a young girl gets into a cab for her daily ride home. She doesn't arrive there and a search is soon started. The real cab driver is soon found and he gives a description of the man who attacked him and the cab is soon found abandoned and examined for forensic evidence. Then all of a sudden a man who fits the description walks into a police station. He is alone and refuses to confirm or deny anything. All he will let the authorities know is that Quincy and Professor Hillman (the kidnapped girl's grandfather) are covering up a murder.
