Chapter 6 - FSK Motives and Profile

Summary

This chapter discusses known motives of female serial killers (FSKs). FSKs’ most common motive for murder was financial gain. An evolutionary psychology model of serial murder is presented. The author discusses how killing children, the antithesis of genesmanship, may be understood from an evolutionary angle. The author reminds the reader that evolved psychology is not an absolute determinant of behavior and that multiple perspectives (e.g., clinical, neural, traumagenic) should be considered to understand a given behavior or mental process. This chapter also presents the outcome (disposition) of serial murder cases in that about 80% were sent to prison, with some receiving the death penalty. This chapter further presents a composite of the “typical” female serial killer (FSK) as described in Harrison et al. (2015) in The Journal of Forensic Psychiatry and Psychology. The author revisits the case of Kristen Gilbert, a FSK whose motives did not neatly fall into a lone typology category. The cases of Judy Buenoano, Rhonda Belle Martin, Lydia Sherman, and Kimberly Clark Saenz illustrate chapter concepts.
