Familicide

A

Type of murder or murder-suicide in which a perpetrator kills multiple close family members in quick succession In about half of all cases the killer lastly kills themselves in a murder-suicide. Between 1900 and 2000 there were 909 victims of mass murder in the US. Of those, more than half occured within an immegiate family Although familicide cases are relatively rare, they are the most common form of mass killings.

David Wilson has divided familicide cases into 4 categories:

  • Anomic

  • Disapointed

Seeks to punish the family for not living up to his ideals of family life

  • Self-Righteous

Destroys the family to exact revenge upon the mother, in an act that he blames on her

  • Paranoid

Q

Serial Murder (Developmental Aspects)

A

Serial murderers Background: There is no single developmental causal factor. Just like all criminals, there are a bunch of risk factors at play that contribute to their ultimate behavior. (Genetics, upbringing,

  • Tend to come from DYSFUNCTIONAL FAMILIES with histories of:
    • Abuse
    • Neglect
    • Domestic violence
  • Alternatively, they may have grown up isolated & lonely in childhood & adolescence.
  • There is NO evidence that serial murders simply have an irrisistable urge to kill or are even psychologically disordered other than their antisocial behaviors.
    • ​Instead, their behavior seems to be based on a sense of satisfaction in their ability to control or dominate, or be the focus of attention.
    • Most of the time there is no identifiable material gain from their actions.
  • The # of perpetrators and victims is difficult to estimate because they often kill STRANGERS – individuals with a low risk of being missed.
    • The strongest determining victim selection factor is that it’s usually those who are most vulnerable or available.
    • If serial murderers are successful with that population, they may move on to more challenging victims.
  • Serial murders are PREMEDITATED and often SEXUAL in nature.
  • At least 400 Serial killers and 4,000 victims in the last century.
    • But some think the victim tally could be 10 times that. That’s because their victims tend to be marginalized citizens who won’t be missed – prostitutes, addicts, hustlers, runaways, etc.
  • Most Serial Murderers have a “comfort zone” – a central point from which they work.
  • Media pays much more attention to WHITE serial killers who attack other WHITE people.
  • FEMALE Serial murderers are rare.
    • They tend to look for some material gain (where men do not)
    • There preferred method of killing is through some chemical like poison or drugs
  • Juvenile Serial murderers are VERY rare, but their motives seem similar to ADULTS by GENDER.
  • Serial murder by children & adolescents are RARE.

Serial Murder (Holmes and DeBurger Typology)

A

Holmes and DeBurger Defined FOUR DIFFERENT TYPES of SERIAL MURDERERS:

  • All are based on MOTIVES:
    • Visionary – psychotic and compelled to murder becasue they hear voices or see images that ‘tell them to kill certain types of individuals’.
    • Mission-oriented – not psychotic, but they also tend to target certain groups of people – people they believe to be immoral or unworthy of life, and they feel the need to rid the world of them. They often feel it’s their duty to clean up society.
    • Hedonistic (lust, thrill, or comfort) – gains pleasure from the pure act of killing. They kill for the thrill. To them (even moreso than other nut-cases, people are OBJECTS to be used for their own enjoyment.
    • Power-seekerkill to exert the control of life or death over others. They are not psychotic, they kill for excitement, but they are obsessed with capturing and controlling their victims and forcing them to obey their every command.
      • Jeffrey Daumer was a serial killer who practiced Cannibalism to assert this control.

      • Methodical
      • Well-planned

      • Low IQ
      • Not socially proficient
      • sloppy and anxious during crime

PROFESSOR COMMENT: Moving forward – The typologies MUST look beyond ONLY motives or ONLY methods and at the very least look at GEOGRAPHIC LOCATION And TYPES of VICTIMS being chosen.

  • We need a more MULTI-DIMENSIONAL TYPOLOGY becasue Serial murders are complex phenomenons and they will require a complex explanation.
