You probably don’t associate psychotic murderers with intelligence. Many of the world’s worst serial killers were smart and cruel.
Smart people who calculated their way to murder for years perpetrated the most horrific and inexplicable atrocities. High-IQ serial killers planned the perfect murder and evaded the police.
A 2005 study indicated that serial killers had an average IQ of 94.7, although many of the most notorious and crafty murderers are geniuses. The sharpest serial killers are Edmund Kemper and John Wayne Gacy. Let’s find out the names of 10 Serial Killers With High IQs.
10. Brian Dugan—140
Brian Dugan, a 140-IQ murderer, is serving life for many rapes and murders. Bedwetting plagued his childhood. He burned down his parents’ garage because he could. Dugan and his brother were sexually raped at Menard Correctional Center for three years after committing petty crimes.
After parole, Dugan committed rape and murder before being apprehended. Kent Kiehl, who has talked to and studied hundreds of psychopaths, does not believe his regret.
“But then you ask them, ‘What do you mean, you feel really bad?’” he explains. Brian will ask, “What do you mean?” Can you help? A hint? Can I call a friend? “They have no way of really getting at that,” Kiehl says.
9. Stephen Christopher Stanko—143
Prisoners are rehabilitated. Stephen Stanko is different. Stanko was released in 2004 after eight and a half years of assault and kidnapping in 1996. After a year on parole with a widower, he moved in with his lover Larua Ling.
The tweet below shows the image of Stephen Christopher Stanko:
Stanko snapped shortly after moving in with Ling, murdering Ling, shooting his buddy Henry Lee Turner, and raping Ling’s teenage daughter before slitting her neck. She escaped and phoned the police, who apprehended Stanko.
Stanko’s motives are unknown, although serial killer paraphernalia was found in his home, suggesting he was obsessed or wanted to be one. He awaits execution.

The terrifying Netflix series Dahmer – Monster: The Jeffrey Dahmer Story has made serial killer Jeffrey Dahmer popular again. Dahmer was a calm, intelligent child who got preoccupied with dead animals as a teenager.

As a youth, he committed crimes and spent three years in and out of mental hospitals without receiving treatment. He then killed unfaithful ladies like his mother. He evaded police twice but was nabbed after being linked to three Texas strangulations.

Gerald and Charlene Gallego were horrible. The married pair kidnapped, tortured, sexually abused, and murdered ten teenagers between 1978 and 1980. The two killed their victims with hammers and strangulation, often as sex slaves.
Charlene, an A-student and violin prodigy, had a privileged upbringing, unlike Gerald, whose mother was a sex worker and his father a criminal who murdered a policeman. Her life changed when she experimented with drugs and alcohol in her teens, bringing her to Gerald.
When arrested, Charlene made a deal with the prosecution to testify against Gerald for a reduced sentence. Charlene served 16 years and eight months before being released, while Gerald died on death row in 2002.

Kaczynski moved to a cabin outside Lincoln, Montana, to live a self-sufficient life. He protested contemporary technology by mailing bombs nationwide. He remained unidentified for 17 years until his manifesto, Industrial Society and Its Future, was published. The Washington Post published parts of it, and Kaczynski’s brother recognized the handwriting and style, leading authorities to him.
The criminal genius was captured in 1996 and pleaded guilty to all counts, receiving eight life sentences in 1998.
