Pieces (1982)

Boston 1942. Young boy makes jigsaw puzzle that has a naked girl in it. His mother finds him making the puzzle and flips out. Boy gets an ax and kills his mother. Police finds him, but they think that the killer is someone else and send the boy to live with his aunt. 40 years later. Young girls are getting killed in Boston campus. Killer cuts of different body parts from them with a chainsaw. Police thinks that the killer might be one of the faculty members so they put an undercover agent in the university to find the killer. Pieces. Yeah, like the title says there are lot of people chainsawed to pieces in this one. Violence is pretty over the top and the killings or actually the results of the killings are pretty graphic. Giallo feel to this movie. Killer putting jigsaw puzzle together with rubber gloves and his identity is not revealed until the very end. Good but not so well known slasher. Definitely worth the look, not your typical teenagers slashed in campus movie. Directed by Juan Piquer Simón who sadly passed away a month ago.
