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.
