6. MOTIVE
Motive is the “why” of the killings
Visionary
• Demon Mandated or God Mandated
Mission-
oriented
• Usually try to justify their acts
Hedonistic
• pleasure in killing
• Lust (sex) or Thrill (pain) or Comfort (material gain)
Power or control
• gain control over victim

7. Visionary
• David Berkowitz
("Son of Sam") is
an example of a
demon-mandated
visionary killer. He
claimed a demon
transmitted orders
through his
neighbor‘s dog,
instructing him to
murder
• 13 victims + 6 hurt

8. Mission-oriented
Justify their acts as "ridding the world" of
a certain type of "undesirable" person,
such as homosexuals, prostitutes,
blacks, Jewish people or Catholics;
however, they are generally not
psychotic.
Some see themselves as attempting to
change the nature of human society,
often to cure a societal ill.
The GREEN RIVER KILLER (Gary
Ridgway)
Killed prostitutes and threw them
into the river (49 victims

9. Hedonistic
• LUST
– Jeffrey Dahmer searched for his perfect fantasy lover —
beautiful, submissive and eternal. As his desire increased,
he experimented with drugs, alcohol and exotic sex. His
increasing need for stimulation was demonstrated by the
dismemberment of victims, whose heads and genitals he
preserved. He experimented with cannibalism to "ensure his
victims would always be a part of him” (17 victims)
• THRILL
– Coral Watts was described by a surviving victim as "excited
and hyper and clappin’ and just making noises like he was
excited, that this was gonna be fun" during the 1982 attack.
Slashing, stabbing, hanging, drowning, asphyxiating, and
strangling were among the ways Watts killed
• COMFORT
– After a murder, a comfort killer will usually wait for a period
of time before killing again to allow any suspicions by family
or authorities to subside. They often use poison, most
notably arsenic, to kill their victims. Female serial killers are
often comfort killers, although not all comfort killers are
female.(Aileen Wuornos)

10. Power/Control
• Many power or control-motivated
killers sexually abuse their
victims, but they differ from
hedonistic killers in that rape is
not motivated by lust but as
simply another form of dominating
the victim
• Ted Bundy traveled around the
United States seeking women to
control
(30 victims)

11. Often, a sexual element is involved with the killings,
– but also motives for serial murder include "anger, thrill,
financial gain, and attention seeking."
The murders may have been attempted or completed in a
similar fashion and the victims may have had something in
common;
– occupation, race, appearance, sex, or age group.
– Anti-social personality disorder or dissocial personality
disorder
Psychopaths lack empathy and guilt, often follow a distinct set
of rules which they have created for themselves.
They may appear to be normal and often quite charming…a
state of adaptation that called the "mask of sanity".

12. Development
Many serial killers have faced similar problems in their
childhood development.
early childhood
trauma
Family, or lack
thereof
The mother
(porn, drugs,
and alcohol)
The serial killer is no different than any other individual who is instigated
to seek approval from parents, sexual partners, or others

14. Research specific questions about your
serial killer:
a. What was their childhood like?
b. Were there any precursors? Did
childhood behavior reflect problems?
c. What was their adult life like? Did they
finish high school/college?
Did they marry? Have children? Were
they loners?
d. Were they ever diagnosed with a mental
disorder? Did they ever receive
treatment?
e. What was the nature of their crimes?
What was the time span for their crimes?
How many victims?
f. What was their behavior like when they
were caught?
g. Were they found capable to withstand
trial?
h. What were they charged with and
sentenced to?
i. Are they still alive? Or did they die
differently than their sentence? Or were
they sentenced to death and executed in
prison?
i. What factors in his childhood and
teenage years attributed to his or her
behavior?
j. Is it genetic, hormonal, biological, or
cultural conditioning?
k. Does the serial killer have any
control over his or her desires?
l. Why was this crime chosen?
m. What type of serial killer is he or
she?
n. Why did he or she choose his or her
method of killing?
o. Do you think that the jury made the
right decision?
p. Was he or she truly rehabilitated? Is
it possible to rehabilitate a criminal?

interviews with 36 serial sex offenders. What might
be the problems with this?

they committed their crimes; planning
and organising, choosing their victim
etc. Problem?
Spoke to male serial sex
offenders only. Problem?

20. The FBI put offenders
into two categories:
Disorganised

systematic
