A spree killer is someone who commits a criminal act that involves two or more murders in a short time, often in multiple locations. There are differing opinions about what durations of time a killing spree may take place in. The United States Bureau of Justice Statistics has spoken of "almost no time break between murders", but some academics consider that a killing spree may last weeks or months, e.g. the case of Andrew Cunanan, who murdered five people over three months, including fashion designer Gianni Versace.
