The discussion notes that female serial murderers are far more deadly and determined, difficult to apprehend, and complexly motivated than her male counterpart. The discussion divides female serial murderers into seven categories. These include the Black Widow, who is the most careful and methodical or murders and kills persons with whom she has a close, personal relationship; the Angel of Death, who often murders in a hospital or nursing home; and the sexual predator, who works alone and is the rarest type of female serial killer. Other categories include the revenge killer, who commits crimes of passion, usually against members of her own family; the murderer motivated by profit or crime; the team killer, who works with other women or men to commit brutal and often sexual murders; and the killer whose sanity is in question. The discussion also emphasizes that the complicated nature of these offenders' crimes makes profiling almost impossible.
