A fascinating look into dimensions of murder that are often overlooked and undeveloped. Spree killing, in particular, is a crime that researchers have vacillated over in the past two decades or so, most notably when the FBI’ s 2005 consortium on Serial Homicide seemed to walk back from the concept because of the implications of the term “ cooling off period.” The author draws the reader into consideration of such classifications, both the spree killer and the mass murderer. It underlines that it’ s often difficult to delineate atypical murderers such as serial killers, spree killers, and mass murderers. It’ s not uncommon for aspects of these behaviors to spill over and overlap with one another. It can be best to stay away from the binary choices of typology and understand the criminal as an individual case
