However, genetics, in tandem with environmental factors such as violent childhood experiences, work together to shape a person. Personal traumas can affect behavioral choices. Found guilty of murdering 13 people in San Francisco and Los Angeles, Ramirez had a disturbed childhood, enduring brutal beatings by his father. Serial killer duo Ottis Toole and Henry Lee Lucas, who were believed to have murdered hundreds of people, were both victims of physical and psychological abuse.
Specifically, they were made to dress up as young girls and then beaten. The connection between genetics, social environment, and criminal behavior appears to be a reality, although in varying degrees across criminals. Understanding the factors that may contribute to serial killer behavior facilitates effective criminal profiling significantly.
At a recent UK conference, researcher Abbie Marono presented findings from her work with ex-FBI profiler Joe Navarro on how different types of childhood abuse can be used to profile serial killers. The study involved examining the association among 4 serial killer typologies — lust and rape, anger, power, and financial gain — and 3 categories of child abuse — psychological, sexual, and physical.
It was also associated with a tendency for overkill, postmortem sex, and moving the body to a different location from where the murder took place. Acts of crime associated with childhood psychological abuse tended to involve torture. A landmark study of 50 serial killers found that childhood abuse was more prevalent in lust serial killers.

For example, serial killer Israel Keyes — who is suspected of killing multiple victims across the country — reportedly tried to make a deal with prosecutors to protect his young daughter from discovering his sinister double life, Ramsland wrote in an article for Psychology Today.
Ramsland questioned, however, just how powerful that protective instinct might have been. Ramsland said the relationship serial killers have with their children can be complicated — and there is no uniform experience.
Some killers like Belle Gunness, who lived in Illinois and Indiana in the late s and early s, are suspected of killing their children. While Gunness was never able to have any children of her own, she served as a foster mother and stepmother to multiple children who died in her care, according to the LaPorte County Historical Society Museum.
After her small farm burned to the ground on April 28, , investigators discovered 13 bodies buried on the property. Another more modern example of a killer who turned against her own offspring is Stacey Castor : a notorious Black Widow who tried to pin the deaths of her two husbands on her daughter by staging a suicide and leaving behind a suicide note that seemed to take credit for the deaths. Kallinger took his son Michael on a killing and kidnapping spree in the s.
Kallinger and Michael, who had been just 13 at the time, broke into homes during the crazed spree, terrorizing the home owners, sexually abusing women, and even killing, The New York Times reported in But not all of his children received the special treatment he gave Michael. He was also later convicted of killing his son, Joseph Kallinger, not long after the year-old had reported him for child abuse, disposing of the remains in the ruble of an old building.
