Following is some some part of my class presentation which can give you knowledge about the serial killers.
WHO IS SERIAL KILLER:
A person who attacks and kills victims one by one in a series of incidents.
A serial killer is typically defined as an individual who has murdered three or more peopleover a period of more than a month, with down time (a "cooling
off period") between the murders, and whose motivation for killing is largely ba
Serial killers are not the same as MASS who commit multiple murders murderers at one time; nor are they SPREE KILLERS, who commit murders in two or more locations with virtually no break in between.
Motivations involved in serial killings are fears of rejection, power, and perfection. Serial killers tend to be insecure, and irrationally scared of rejection.
PEOPLE BECOME SERIAL KILLER MAINLY FOR SPRITUAL REASON.
SPRITUAL KILLER EVEN KILL HIS OWN CHILD IN ORDER TO HONOUR GODS AND GODESSES.
MENTAL DISORDER IS ALSO THE MAIN REASON FOR SERIAL KILLING
Many serial killers have faced similar problems in their childhood development.
Almost all of the serial killers in the study had experienced some sort of environmental problems during their childhood, such as a broken home, or a lack of discipline in the home.
If a child receives no support from those around him or her, then he or she is unlikely to recover from the traumatic eventin a positive way
LUST KILLING : Sex is the primary motive of lust killers, whether or not the victims are dead, and fantasy plays a large role in their killings. Their sexual gratification depends on the amount of torture and mutilationthey perform on their victims. They usually use weapons that require close contact with the victims, such as knives or hands. As lust killers continue with their murders, the time between killings decreases or the required level of stimulation increases, sometimes both.
THRILL:The primary motive of a thrill killer is to induce pain or create terror in their victims, which provides stimulation and excitement for the killer. They seek the adrenaline rush provided by hunting and killing victims. Thrill killers murder only for the kill; usually the attack is not prolonged, and there is no sexual aspect. Usually the victims are strangers, although the killer may have followed them for a period of time. Thrill killers can abstain from killing for long periods of time and become more successful at killing as they refine their murder methods.
COMFORT(PROFIT):Material gain and a comfortable lifestyle are the primary motives of comfort killers. Usually, the victims are family members . 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. Dorothea Puente killed her tenants for their Social Security checks and buried them in the backyard of her home. H. H. Holmes killed for insurance and business profits.
KILLING FOR MONEY: SOME SERIAL KILLERS KILL PEOPLE AND DISSOLVE BODIES IN ACID AND TAKEOUT BONES AND BODY PARTS & SELL FOR MONEY.
