[A serial killer as exemplified by T. R. Bundy].

The question of serial homicides and their perpetrators poses a considerable problem of both a definitional and practical nature. T R. Bundy is the first perpetrator who was officially termed a "serial killer". Since that time, this concept has been commonly used and sometimes even overused, e.g. in reference to mass murderers. However, the definitions established for Bundy's case have been preserved and continue to be used in practice.
