Recommendations While serial killers fascinate and continue to dominate the pop culture landscape, research into the contributing factors surrounding multiple homicidal behaviors has been, at best, limited. However, recent research has found that "certain factors related to a serial killer's childhood may influence their future criminal behavior" (Keatley, Shephard, Golighty, Yaksic, Reid, 2018, p. 3), specialists in behavior having found that a significant proportion of serial killers were victims of physical violence at the hands of a parent during their childhood.
