Serial Killers
“We serial killers are your sons, we are
your husbands, we are everywhere.
And there will be more of your children
dead tomorrow.”
“You feel the last bit of breath leaving
their body. You’re looking into their
eyes. A person in that situation is God.”
~ Ted Bundy

Definitions of a Serial
Killer
 Someone who murders at least 3
people in more than a 30 day
period
Someone who murders 2 or more
victims with an emotional cooling
off period between the homicides
Someone who over time commits
at least 10 homicides which are
violent and brutal and ritualistic
Profiling Beginnings
 UNSUB-unknown subject
 “If you want to understand the
artist you have to look at the
painting”
 What took place?
 Why did it happen the way it did?
 Who could have committed this
crime for these reasons?
Inside the Mind of a Killer
They sense weakness and vulnerability
Thrill of the hunt gets them going
Behavior reflects personality
“Homicidal triad”-cruelty to small
animals, fire-setting and bedwetting
beyond an appropriate age
 Three most common motives of serial
killers and rapists are DOMINATION,
MANIPULATION and CONTROL
 Serial killers are sexual predators



Inside the Mind…
 One of their main fantasy jobs is police
officer
 Many are “police buffs”-they hang out
at police bars and talk shop. They also
like to find out about the investigation
 Triggering event-”stressor”-most
common are losing job and losing
wife/girlfriend
Inside the Mind…
 Most single important factor in the
development of a serial killer is the role
of fantasy
 Many fantasize about a relationship
between sex and death (Ed Kemper,
Jeff Dahmer)
 Behavior escalates from fantasy to
reality, helped along by pornography
and cruelty to animals and peers.
Fantasy is in place long before murders
start
The Role of Fantasy
 82% of serial killers report daydreaming
in their childhood accompanied by
compulsive masturbation. If fantasies
are violent, violence and sex become
associated with one another
 71% report feeling isolated as children.
Isolation encourages substitution of
fantasy for human contact
The Role of Fantasy:
Test Runs
 Serial killers start out by giving the
fantasy a test run
 This involves cruelty to animals
and small children
 Stealing women’s underwear,
exhibitionism, voyeurism, burglary
and other minor offenses
A Theory…
 66% of sexual and serial killers
report their mother as the
dominant parent
 S.K. rooted in gender identification
 If mother is too dominant, boys
cannot achieve masculinity which
creates rage
 Rage is focused on females
Organized or
Disorganized?
Organized
 Continual refinement
of fantasy
 Improvement of
details from one
crime to the next
 Obsession with detail
 Planning of crime
and disposal of body
 Socially competent
 Follows crime in the
news
Disorganized
 Bodily mutilation
 Lack of preparation
 Body left in view
 Violence is sudden
 Often they are
severely disturbed
 Some UNSUBS are
mixed
Deciphering Crime
Scenes
 Blitz style attack or attack on small or
physically challenged people means
attacker has little confidence and selfesteem, not charming, asocial type
 Sexual attacks on the elderly mean the
person has little or no sexual
experience
Deciphering Crime Scenes
 Severe facial trauma/covering the face
means the person may have known the
victim or is trying to depersonalize her
 Covering the entire body means the
person feels bad about what he did
 Multiple stab wounds mean a lot of
anger and emotion (think about 30 stab
wounds)
M.O. vs Signature
Modus Operandi
 Learned behavior
 What the UNSUB
does to commit
the crime
(shooting,
stabbing)
 It can change
Signature
 What the UNSUB
does to fulfill
himself
 Does not change
 Expresses the
UNSUB’s
personality
 He NEEDS to do it
History of Serial Killing
 Serial killing may be a much older
phenomenon than we realize
 Stories about witches, werewolves,
vampires may have been created
to explain atrocities committed by
humans (Chikatilo)
 Beowulf-Grendel
