Many serial killers experienced traumatic events during childhood that may have contributed to their violent crimes later in life. Childhood trauma can include physical, emotional, or sexual abuse, neglect, abandonment, domestic violence, or other adverse experiences. While not all who endure childhood trauma become killers, research suggests a strong link between early trauma and violence.
Jeffrey Dahmer
Jeffrey Dahmer murdered 17 men and boys between 1978 and 1991. His father was largely absent due to work and his parents had a turbulent marriage characterized by frequent arguing. Dahmer underwent a hernia operation around age 4 and developed a fear of being abandoned at the hospital. He became insecure and withdrawn. His mother was unstable due to mental illness and attempted suicide by overdosing on pills when he was a teen. Dahmer committed his first murder weeks after she left his family.
Ted Bundy
Ted Bundy raped and killed over 30 women in a rampage during the 1970s. His mother Eleanor Cowell gave birth to him as an unwed mother and raised him to believe his grandparents were his actual parents. He did not learn the truth about his mother’s identity until high school. Bundy described his grandfather, with whom he lived, as a tyrannical racist prone to violence. Some experts believe he was rejected by his mother early on and her secrecy led to lifelong feelings of distrust and abnormal development.
John Wayne Gacy
John Wayne Gacy sexually assaulted and murdered at least 33 teenage boys and young men in the 1970s. His father was an alcoholic prone to beating his wife and children with a razor strap. Gacy’s sister said their mother spread lies that Gacy had injured or molested his sisters to justify beating him. At age 11, a friend of his father’s molested Gacy. His father accused him of making it up to cover up his “wrongdoings” and beat him again. The repeated physical and emotional abuse likely damaged Gacy.
Gary Ridgway
Gary Ridgway, the Green River Killer, murdered at least 49 women over two decades beginning in 1982. When he was 16, he stabbed a 6-year-old boy who survived. His mother reportedly controlled him obsessively and he harbored resent toward her. At age 13, he led a 6-year-old girl into the woods and choked her unconscious to satisfy a strangling fetish. His bedwetting into adolescence suggests childhood trauma. He despised prostitutes as figures resembling his mother, whom he wanted to kill.
Dennis Rader
Known as the “BTK Killer,” Dennis Rader murdered 10 people between 1974 and 1991. He exhibited strange, harmful behaviors from childhood like hanging cats and dogs. He had a cold relationship with his mother and was terrified by her punishments and explosive temper. Rader set fires and stole underwear as a child. His parents divorced when he was 9 after years of conflict. The abandonment and exposure to a volatile home life appeared to damage Rader emotionally.
Edmund Kemper
Edmund Kemper killed 10 people including his grandparents and mother in the 1970s. His parents divorced and he had a chaotic upbringing shuffled between abusive relatives. His mother locked him in the basement “because she was afraid of him,” verbally abused him, and made him sleep in a windowless bunker. He mutilated animals and acted out violently, leading to juvenile detention. His mother’s cruelty helped give rise to his rage and crimes.
Henry Lee Lucas
Henry Lee Lucas confessed to hundreds of unverified murders, but was convicted of 11 killings in the 1970s and 1980s. He endured an appalling childhood of extreme neglect and abuse. His father lost his legs in a railroad accident when Lucas was young and would force the boy to watch him have sex with prostitutes. His alcoholic mother beat him regularly, dressed him in girls’ clothes, and forced him to watch her have sex with strangers. The unimaginable early trauma spawned his deviant desires.

Impacts of Childhood Trauma on Serial Killers
There are common themes seen in the early lives of notorious serial killers that may have laid the groundwork for their predatory crimes:
Disrupted family dynamics
Many serial killers grew up in unstable or broken homes, often with absent fathers and volatile mothers. Divorce or parental substance abuse created chaotic homes. The lack of security damaged their attachment and resulted in personality disorders.
Physical, emotional or sexual abuse
Persistent abuses like beatings, humiliation, and molestation were present in most serial killers’ histories. Abuse skewed their developing views on relationships and desensitized them to harming others. It contributed to pathological urges and violent behaviors.
Early warning signs
Many future serial killers exhibited disturbing tendencies in childhood like setting fires, mutilating animals, or hurting other children. Their violent fantasies and acts were often minimized or ignored by parents. Unchecked, their compulsions escalated over time.
Isolation and social deficits
Due to factors like parental neglect, overprotectiveness, or constant moving, many serial killers had trouble bonding with others. Their poor social skills fed feelings of alienation later exploited to lure victims. Their lack of empathy or remorse aided their crimes.
Unprocessed psychological damage
The intense pain of serial killers’ childhoods -from fear of abandonment to molestation- was buried and left to fester. Their warped views of self, distorted sexuality, and rage grew uncontrolled. The ruthlessness and pathological nature of their murders suggest underlying quests to vent their past trauma.
Case Studies in Traumatic Roots of Serial Killers
Looking closely at two serial killers’ backgrounds provides insight into how childhood trauma can forge killers:
David Berkowitz – “Son of Sam”
David Berkowitz murdered 6 people in New York City shootings from 1976-1977. He was born to an unmarried woman who gave him up for adoption. His new parents doted on him initially but became distant after having another son. Berkowitz engaged in aberrant behaviors like firestarting and was destructive. At 14, he learned his birth mother had died years before, devastating him. His adoption plus loss of his birth mom left him with deep feelings of rejection, warped views of women, and violent tendencies.
Richard Ramirez – “Night Stalker”
Richard Ramirez killed 13 people in California in the 1980s. His father was abusive and unstable. He witnessed him beat his wife and tortured animals in front of his son. An older cousin introduced Ramirez to drugs, Satanism, and sexualized photos of his wife as a teen. He grew up hypersexual, alienated, and surrounded by violence. He dropped out of school early. The combination of an abusive home, family sexual deviance, and isolation primed Ramirez for his brutal crimes targeting women.
Conclusion
While adverse childhood events alone do not determine who becomes a serial killer, research has established they contribute to the warped psychology behind these unconscionable crimes. The troubled backgrounds of many notorious serial killers followed similar dark trajectories of unstable homes, childhood abuse, social isolation, and violent thoughts or acts that went unaddressed for too long. Their early traumas shaped twisted perceptions of power and control and crushed their humanity. Public understanding of the traumatic roots of serial killers may help prevent and treat child abuse to reduce violence in society.
