What is the title of the old movie where a murderer was hiding in the floor boards?

He killed someone and hid in the floor boards and locked the door so it looked like suicide. It's an old movie
Update: he was caught when a detective went back to the apartment where the suicide had been. A piece of furniture was moved over the spot where the murderer was hiding in the floor boards. He started screaming and the detective found him.
Update 2: it's a very old movie. Possibly more than 30 years so it's not tell-tale
