Egger (1) claims that "there are no known serial killers who are female" (p.348). This is clearly not accurate. Newton (1993) has compiled an exhaustive accounting of 183 female murderers, finding that 70% meet the definition of a serial killer. Victim-wise, these female serial killers showed a different profile than males: 45% killed family members, 26% murdered friends or acquaintances, 10% took the lives of those left in their care (wards, charges or patients), 19.5% were "mixed" predators, while only 11% murdered strangers. And while almost all male serial killers fall into the "motiveless" category, 35% of the females killed for profit, 28% due to mental illness (delusions or command hallucinations) and only 8% killed for "sadistic thrills". (About 9% of the documented female serial killers were motivated by drug trafficking, jealousy, mercy or religion, combined.) Method of killing followed the pattern for males outlined above.
