kvindelige seriemordere
A gendered true crime term for a woman who commits serial killings, defined under federal law as three or more killings with common characteristics suggesting the same perpetrator, without gender-based legal distinction.

Definition
Female serial killers are women who commit serial killings as defined in federal statute. Under 28 U.S.C. § 540B, serial killings constitute a series of three or more killings, not less than one of which was committed within the United States, having common characteristics such as to suggest the reasonable possibility that the crimes were committed by the same actor or actors. The statute defines "killing" as conduct that would constitute an offense under 18 U.S.C. § 1111 if federal jurisdiction existed.
The term "female serial killer" is a descriptive, gender-specific label used primarily in criminological research and true crime discourse. It does not represent a distinct legal category under federal or state criminal law. Federal statute makes no distinction between male and female perpetrators in defining serial killings; the gender designation serves only to identify the sex of the offender, not to establish separate legal elements, defenses, or sentencing considerations.
Under 28 U.S.C. § 540B, the Attorney General and the Federal Bureau of Investigation are authorized to investigate serial killings upon request from the head of a law enforcement agency with investigative or prosecutorial jurisdiction over the offense. This investigative authority applies regardless of the perpetrator's gender. The underlying criminal liability for each individual homicide is prosecuted under applicable federal or state murder statutes, with the serial nature of the offenses potentially influencing charging decisions, sentencing recommendations, and the allocation of investigative resources.
In true crime analysis, the term is used to examine patterns, methods, and motivations that may differ statistically between male and female serial offenders, but these differences carry no independent legal significance. All serial killings, regardless of the perpetrator's gender, are subject to the same constitutional protections, evidentiary standards, and sentencing frameworks applicable to homicide prosecutions generally.
