What does the research tell us about gender differences and serial murderers?

Research indicates that gender differences among serial murderers are significant, with males constituting the vast majority of known cases. Male serial killers often exhibit traits such as aggression, dominance, and a history of violence, while female serial killers may exhibit more relational motives, often using methods like poisoning. Additionally, female serial killers typically have different victim profiles, often targeting those they know, such as family members or partners. Overall, while both genders engage in serial murder, their motivations, methods, and victim choices tend to differ markedly.
