A spree killer is someone who embarks on a murder"rampage". This is an ambiguous term, related to mass murderer and serial killer. The Bureau of Justice Statistics defines a spree killing as: "[involving] killings at two or more locations with almost no time break between murders." The definition is especially close to that of a serial killer; perhaps, the primary difference between the two is that a serial killer tends to "lure" victims to their death; whereas, a spree killer tends to go "hunting".
