6 F.B.I Definition of “Serial Killing” “The term ‘serial killings’ means 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”(Title 18, United States Code, Chapter 51, and Section 1111).
7 Who are serial killers? Average age 30 years old 95% male, 5% female (Why more men than women?)73% white, 22% black, 1% otherAverage or low IQ median IQ of 95 from sample of 174 serial killersFetishism-sexual attraction to a part of the body or objectPartialism-atypical sexual interest in a part of the body (armpits, breasts, buttocks, navel, hands and feet are most common)Necrophilia-sexual attraction to corpsesVarying degrees of psychopathyQUESTION-How do fetishes or partialism develop?
8 The Insanity DefenseThe legal concept referring to the criminal’s state of mind at the time the crime was committed. It requires that, due to mental illness, a defendant lacks moral responsibility and culpability for the crime and, therefore, should not be punished.(Source: Forensic and Legal Psychology, 2012)
9 Test #1-The M’Naughten Rule (Right-Wrong Test) M’Naughten Rule (1843)-at the time of committing the act, the party accused was unable to distinguish right from wrong because of a disease of the mind (over 50% the states in U.S. use this test)Question-Why is this hard to prove in court?
10 Test #2-ALI/MPC Test for Insanity (American Law Institute, Model Penal Code) ALI/MPC Test –also known as the substantial capacity test, the ALI/MPC test states a person is not responsible for criminal conduct if at the time of such conduct, as a result of mental disease or defect, he/she lacks substantial capacity either to appreciate the criminality (wrongfulness) of his/her conduct or to conform his/her conduct to the requirements of the law(used by Federal Government and a few states)
11 Test #3-Irresistible Impulse Test The defense must show the defendant knew his or her actions were wrong and were unable to resist the urge to commit the crime.Interview 0 to 3 min.
12 GBMI-Guilty But Mentally Ill Dennis Rader-BTK KillerDefendant is found guilty and is sentenced to prison for a period consistent with that verdict. Defendant receives treatment for mental health issues while in prison or is transferred to a secure mental health facility(13 states currently use this).Interview 18 min. to 24:50

14 The Four Major Risk Factors Antisocial personality patternHistory of antisocial behaviorAntisocial attitudesAntisocial associates Nicole Simpson
15 Anti-social personality disorder A pervasive pattern of disregard and violation of the rights of others, occurring since age 15 years old.Deceitfulness and manipulative-lying, conning othersImpulsive or failure to plan aheadAggressive/irritability-repeated fights or assaultsReckless disregard for safety of self or othersConsistent irresponsibility-work behavior/financial responsibilityAt least 18 years oldLack of remorse-indifferent to or rationalizing harm to othersBehaves in a ways likely to be arrestedOutward appearance of normal behaviorUnresponsive to social control(Source-Diagnostic & Statistical Manual of Mental Disorders, 5th ed.)
16 Key Features of Psychopathy Disregard for right and wrong; manipulativePersistent lying or deceit to exploit others; superficial charmUsing charm or wit to manipulate others for personal gain or for sheer personal pleasureIntimidation, dishonesty and misrepresentationHostility, significant irritability, agitation, impulsiveness, aggression or violenceLack of empathy for others and lack of remorse about harming othersIrresponsible work behaviorFailure to learn from the negative consequences of behavior

19 Diphasic (two) Personality Formation WHO AM I? One phase is the fantasy life where the child has complete control and then the adult. This is the hidden personality that dreams and fantasizes about killing.The other phase is the shell that walks through the real world and has little energy or effort committed to it.
20 The Psychological Signature Signature killers comprise the majority of serial killersThe signature is the psychological “calling card” or “personal stamp” that he leaves at each crime scene and what fulfills himThe “signature,” crudely put, is “what the killer gets off on” based on years of violent dreams and fantasies(Source: John Douglas, Federal Bureau of Investigation, 2010)
21 The SignatureThe signature is often an unconscious pattern that may include:type of victim selectedmethod used to control the victimtypes of wounds inflictedany post-mortem activity with the bodybody disposal or dump site
22 Technology to capture killers REJIS-Regional Justice Information ServicesMULES-Missouri Uniform Law Enforcement ServiceNCIC-National Crime Information CenterHITS-Homicide Investigation Tracking SystemAFIS-Automated Fingerprint Identification System (Che Sims story)
23 Conclusion and Questions Serial killers are not born violent. They become killers after years of fantasizing about fulfilling their anti-social needs.The signature drives a person into a diphasic personality formation, a public personality that may seem very normal/friendly and the “human hunter” personality to satisfy deep psychological needs.There is no cure for serial killers.
