Serial murder usually refers to incidents in which an individual (or individuals)
separately kills a number of people (usually a minimum of three) over time. The
cooling-off period for serial killers may be days or weeks but more likely months or
years.
Myths Regarding Serial Killers
The first myth is that serial killers are all “dysfunctional loners.” According to the FBI, most
serial killers are not reclusive misfits who live alone. They do not appear as monsters and may
live and work in plain sight within their communities.
Developmental Aspects of Serial Killers
A vast majority of future serial killers grew up in dysfunctional families with histories of
abuse, neglect, and domestic violence, but this is not always the case.
Serial Killer Phases (Norris, 1988; Ressler et al. 1988)
Not all theorists believe such phases exist.
The aura phase consists of a withdrawal from reality and a heightening of the senses. This may
last anywhere from several moments to several months and can begin as an extended and
prolonged fantasy.
The next phase is the totem phase in which many, but not all, serial killers seek a memento of
their kill by taking artifacts belonging to the victim, removing or eating part of the body,
removing and wearing the skin, or taking photographs.
A depression phase sometimes occurs after a kill when the satisfaction achieved from the killing
begins to wane (explaining to some extent the need for the totem).
Visionary Type
The Visionary type of serial killer is psychotic. He or she often hears voices or sees visions and
is driven to kill by these hallucinations or by delusions.
Mission-oriented Type
Hedonistic Type
The hedonistic type of serial killer gains pleasure from the pure act of killing. To
The Power-seeker
The Power-seeker desires complete control over the life and death of others. Jeffrey Dahmer
practiced cannibalism to have ultimate control over his victims by bringing them alive in him.
Organized Killers
Organized killers are of at least average intelligence and are socially competent. They are able
to control their emotions during the actual crime and tend to be methodical and well-planned in
their actions. After the killing has taken place, they enjoy following their crimes in the news.
Disorganized Killers
Disorganized killers often have a below average intelligence and are not socially
Examples of serial killers

dead).

SUMMARY
Mass murder is defined as the killing of three or more persons at a single location with no
cooling-off period. Accordingly, most mass murders take place in a matter of minutes or hours.
Depending on their motive, mass murderers are classified in one of the following groups:
disciple killers, family annihilators, pseudocommandos, school shooters, disgruntled employees,
or set-and-run killers.
Disgruntled Employees are often former employees of a company who retaliate after being
disciplined or dismissed. Set-and-run killers may also be motivated by revenge but kill from a
distance by planting a bomb or setting a time device so that the murderer is far away when the
explosion occurs.

killers.
