La morte risale a ieri sera (also known as Death Occurred Last Night and Death Took Place Last Night) is a 1970 giallo film directed by Duccio Tessari. Written by Biagio Proietti, the film is based on the novel I milanesi ammazzano al sabato by Giorgio Scerbanenco. La morte risale a ieri sera stars Raf Vallone and Frank Wolff. The film's score was composed by Gianni Ferrio, whose baroque and psychedelic contributions to the soundtrack were described by one critic as inconsistent with the tone of the film.
Following the disappearance of his beautiful but mentally handicapped daughter, Avanzio Berzaghi (Raf Vallone) travels to Milan to track her down. Local detective Duca Lamberti (Frank Wolff) investigates the city's pimps and prostitutes for clues, eventually finding the girl's burnt body in a field. Berzaghi vows to find the girl's murderer, eventually tracking down his quarry. Berzaghi exacts his revenge, but finds no satisfaction from having done so.
