It establishes the FBI’s definition of a serial killer and presents criminological data showing that the number of active offenders has significantly dropped since the peak in the 1970s and 1980s. The episode attributes this decrease to several factors, including advancements in forensic technology like DNA profiling, improved law enforcement coordination through programs like ViCAP, and societal changes that limit potential victims' vulnerability.
