Please, I need to find this movie fast. The movie starts with a serial killer who uses piano strings to hang his victims. During this movie, appears a magician(I dont know the word now) who, blindfolded, can touch the person and gather information through them. He touches the serial killer, locks himself in his thing(I dont know the word now) and calls the police. The says he needs a proof, the magician touches the chair he sat and they know the adress of his house. They go to his house, and the police is the serial killer.
