(FBI), the general definition of "spree killer" is a person (or more than one person) who commits two or more murders without a cooling-off period; the lack of a cooling-off period marks the difference between a spree killer and a serial killer. The category has, however, been found to be of no real value to law enforcement, because of definitional problems relating to the concept of a "cooling-off period". Serial killers commit clearly separate murders, happening at different times.

Mass murder Mass murder is the act of murdering a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. The United States Congress defines mass killings as the killings of three or more pe ...

ers are defined by one incident, with no distinctive time period between the murders. How to distinguish a spree killer from a mass murderer, or from a serial killer, is subject to considerable debate, and the terms are not consistently applied even within the academic literature. For example, ''The Encyclopedia of Crime and Punishment'' lists five different categories of spree killers and cites Mark O. Barton as an example of the second one. He is also noted alongside mass murderers, such as

In ''Controversial Issues in Criminology'', Fuller and Hickey write that " e element of time involved between murderous acts is primary in the differentiation of serial, mass, and spree murderers", later elaborating that spree killers "will engage in the killing acts for days or weeks" while the "methods of murder and types of victims vary".

as examples of spree killers. Ronald and Stephen Holmes define serial murder as "the killing of three or more people over a period of more than 30 days, with a significant cooling-off period between the killings." Under this definition, Andrew Cunanan would be categorized as a serial killer and not a spree killer. Douglas wrote that the identity of a serial killer is generally unknown until they are caught, and a mass murderer's identity is learned only after they have committed the crime. The identity of the spree killer, on the other hand, usually becomes known by police while the spree is still in progress.
