A serial murder is most often defined as two or more killings committed between an undefined span of time between murders.
The quantitative definition is necessary to distinguish a serial murder from other categories such as single murder and mass murder, while the temporal separation is a common trait among serial murderers because they need emotional cooling-off period before they kill the next victims.
The topic of serial murder almost always attracts great interests from the media, academia, medical experts, mental health professionals, and the general public.
Within the criminal justice community, a serial murder most likely brings serious investigative challenges to law enforcement.
Even people who call themselves professional or expert investigators often conduct independent work to identify or perhaps apprehend potential suspects.
While there is no single identifiable factor that motivates a person to develop into serial killer, early childhood behavior problems and psychological trauma due to neglect and abuse as well as juvenile delinquency have been shown to increase risk of future violence.
“This is not to say that everyone with troubled childhood or upbringing would grow up to be serial killers; however, some serial killers did experience childhood adversity or develop tendency to disregard the law and display the lack of moral compass during their formative years.”
The following list gives a brief overview of some infamous serial killers and the disturbing acts they did when they were or teenagers.
10 Charles Manson, An “Aggressive Antisocial”
An American cult leader and serial killer, Charles Manson and his loyal young disciples are thought to have committed at least 35 murders throughout their lifetime, but most notoriously active during the 1960s. Manson himself died in 2017 after spending more than 40 years in prison.
When he was just a 5-year old boy, his alcoholic mother was arrested and sent to jail along with his older brother for armed robbery.
The mother was paroled three years later, but then she ended up abandoning him at age 12. She gave him away to a children’s home where Manson lived much of his youth. He made attempts to return to his mother, but all he received was rejection.
This was the point when Manson started his criminal career on the street by robbing cars and service stations. Over the next 20 years or so, Manson spent his life in and out of reform schools and prison for various crimes.
He was actually detained at one time during his youth, and the caseworker who apprehended him described young Charles Manson as aggressively antisocial.
