WHAT IS PSYCHOLOGICAL PROFILING?
PSYCHOLOGICAL PROFILING
• Psychological profiling involves investigating an
offender's behaviour, motives and background in
an attempt to further guide an investigation.
• Analyzing the criminal's habits and rituals allows
investigators to trace similarities between
previous crimes. When these details of their
lifestyle are made public, friends, neighbours and
colleagues may recognize them.
PSYCHOLOGICAL PROFILING
• The process of psychological profiling began over a
century ago, but was first distinctly used as a method
in America during the 1950's.
• Investigators discovered through research, intriguing
patterns and similarities between serial killer's
behaviour. Some of the patterns discovered include
the killers having suffered from child abuse as
youngsters, whether it is sexual or physical and that
this kind of abuse led to abnormal behaviours later
on.
MACDONALD TRIAD (TRIAD OF SOCIOPATHY)
• The triad links animal cruelty, obsession with fire
setting, and persistent bedwetting past the age of
five in children and teenagers to violent behaviours;
particularly homicidal behaviour.
• Late teenage years to early twenties, these
individuals were engaging in petty crimes and
defying authority.
• Although other studies have not found statistically
significant links between the triad of violence and
violent offenders, many serial killers exhibited these
behaviours during childhood. http://en.wikipedia.org/wiki/Macdonald_triad
APPLICATION OF MACDONALD TRIAD
• Dennis Lynn Rader is an American serial killer
who murdered ten people in Sedgwick County
between 1974 and 1991.
• He is known as the BTK killer (or the BTK
strangler). "BTK" stands for "Bind, Torture, Kill,"
which was his infamous signature. He sent letters
describing the details of the killings to police and
to local news outlets during the period of time in
which the murders took place.http://dennisraderbtk.blogspot.ca/
TYPES OF SERIAL KILLERS
• Visionary Type: such murderers kill in response to
the commands of voices or visions usually emanating
from the forces of good or evil. • Often believed to be suffering from some form
of psychosis.
• Mission-Oriented Type: these offenders believe it is
their mission in life to rid the community or society of
certain groups of people. • Some killers may target the elderly,
prostitutes, children, or a particular racial/ethnic group.
TYPES OF SERIAL KILLERS
• Hedonistic Type: offenders in the category are usually
stereotyped as ‘thrill seekers’, those who derive
satisfaction from the murders. ‘Lust murders’
• Often referred to as sexual and sadistic (deriving
pleasure from inflicting pain and suffering)
• Power/Control-Oriented Type: primary source of
pleasure is not sexual, but the killer’s ability to control
and exert power over his helpless victim
• Murders for Profit: offenders murder individuals in
order to make a profit
TYPES OF MURDERERS
Through profiling techniques, the FBI has
identified characteristics of ‘organized’ and
‘disorganized’ murders

PSYCHOPATHR
Robert Hare, a researcher in the field describes
psychopaths as "intraspecies predators who use
charm, manipulation, intimidation, sex and violence to
control others and to satisfy their own selfish needs.
Lacking in conscience and empathy, they take what
they want and do as they please, violating social
norms and expectations without guilt or remorse".
"What is missing, in other words, are the very
qualities that allow a human being to live in social
harmony."
PSYCHOPATH
Psychopaths are superficially charming, and many
psychopaths are excellent mimics of normal human
emotion; some psychopaths can blend in,
undetected, in a variety of surroundings, including
corporate environments. There is neither a cure nor
any effective treatment for psychopathy; there are
no medications or other techniques which can instill
empathy, and psychopaths who undergo traditional
talk therapy only become more adept at
manipulating others.
