Murder for profit or crime Killer whose sanity is in question Team killer Sexual predator. The sexual predator is defined as women who commit based upon sexual motivation.
The serial murderer Jeffrey Dahmer would go to bars in Milwaukee, Wisconsin, and pick up young men, sometimes telling them he was a photographer and luring them back to his apartment with an offer of money to be his model.
He would then drug their drinks to subdue them so that they would be easier to strangle. However, those factors did not tell investigators the emotional core of his killing, they were simply the modus operandi MO of the crime. MO includes victim type, how the criminal approached or overcame his victim, tools used, and the time and place that the crime occurred.
More revealing is what has been called a killer's "signature," which has been defined by John Douglas as "a personal detail that is unique to the individual, why he does it: John Douglas, the first full-time profiler at the behavioral science division of the Federal Bureau of Investigation Academy in Quantico, Virginia, thinks the killer's signature is a better guide to behavior than his MO.
While the MO may change as the killer comes up with a better technique, the emotional reason he commits the crime does not change. In Dahmer's case his murder signature showed the sadistic sexual satisfaction and control of living with his victims' bodies.
In his case, some of these behaviors included engaging in sex with the bodies, cutting up the victims and cannibalizing body parts such as the heart, pulling muscles from the bone and wearing them on his own shoulders, painting the skulls to put over his bed, and storing one victim's head in the refrigerator.
Characteristics of Serial Murder What is serial murder? The British author John Brody first used the term inand the National Institute of Justice defined serial murder in as "a series of 2 or more murders, committed as separate events, usually, but not always, by one offender acting alone" Newtonp.
Another perspective is that of Steve Egger, who uses six characteristics in his definition of serial murder: Several of these characteristics are debatable. The material gain motive is more common with the female than the male style of serial murder, thus Egger's definition could be seen more as serial signature murder.
Also, individuals such as Edmund Kemper, who killed his grandparents and mother, and Henry Lee Lucas, whose mother was his first victim, are generally classified as serial killers.
The criminologist Eric Hickey states that most researchers define serial killers as having three to four victims, but also includes in his database of serial killers some individuals who "killed only two victims but were suspect in other slayings or in which evidence indicated their intent to kill others" Hickeyp.
The problem with using a definition based strictly on three victims omits the two-time signature killer who has obsessive qualities and would be expected to continue to kill. Serial murder differs from mass murder in that mass murder involves killings of four or more victims in the same general area and occurs as one event in a short period of time.
The mass murderer "appears to give little thought or concern to his or her inevitable capture or death" and may give him- or herself up or commit suicide if not killed by police ibid.
Characteristics of the Serial Killer According to Hickey's database of approximately serial killers, the average age of the murderer at the time of the first killing was Fox and Jack Levin found that males made up more than 90 percent of the sample.
Seventy-three percent of male offenders were white, 22 percent were African-American, and the remainder were of different ethnic groups. Fox and Levin report that the researcher Grover Godwin's database of serial killers revealed an average age of thirty.
Ninety-five percent were males, 5 percent were females, and 16 percent were African-American.
Godwin also found that only 4 percent of his sample graduated with a bachelor's degree, while most were employed in blue-collar jobs. Victims were 67 percent female, with children, prostitutes, and the elderly as other preferred victim categories, although 20 percent of Godwin's sample were males who had additionally been raped by their attackers.The research that I have gathered about serial killers focuses on their childhood development, the differences and similarities between men and female serial kills, and finally general information on ho.
