RIS Delitti Imperfetti is an Italian television series, created in 2004 by Daniele Cesarano, Barbara Petronio and Leonardo Valenti, broadcast since January 2005 on Canale 5. The title, where RIS is an acronym for Reparto Investigazioni Scientifiche (an actual, real-life unit of the Carabinieri, the Italian gendarmerie), could be approximately translated into English as Unit of Scientific Investigations: Imperfect Crimes.
