Modus operandi (often used in the abbreviated forms M.O. or simply method of operating) is a Latin phrase, approximately translated as "method of operating".[1] The plural is modi operandorum ("methods of operating"). The term is used in English to describe someone's habits or manner of working, the method of operating or functioning.
It is often used in a criminal sense to profile the methods employed by individuals during the execution of a crime and may also be used in offender profiling,[2] where it can also be used to find clues to the perpetrator's psychology.[3] It largely consists of the methods used to execute the crime, prevent detection, and facilitate escape.[1]
In Criminal Investigation Berg explains that a suspect's modus operandi (MO) can help in identification, apprehension, or repression. An M.O. file is an orderly method of recording and coding information designed to reveal habits, traits, or practices of criminal suspects. This can be used to apprehend a suspect.
