WESTBOROUGH, MA January 13, 2018 The true incidence of violence among people diagnosed with a nervous and mental disorder is quite low. It is a common misconception that whenever something hideous occurs it must be “mental illness” that is the driving force behind its fury. Occasionally this is true but much less than one may anticipate. I have written on those with both mental illness and co-occurring substance abuse in prior posts (Sefton, 2017a, Sefton, 2017b). In most cases mental illness alone
is neither the reality nor the underlying cause of terminal rage. In light of the information being uncovered about the Newtown, CT mass murderer, the specter of mental illness insures a convenient scapegoat. Updated information from Newtown recently confirmed that Adam Lanza had studied the media stories of prior mass killings as he planned for his despicable finale. In retrospect, I wonder what “red flags” have been uncovered that offer insight into his substantive motivation. People will speculate about random causes of Lanza’s behavior unless it can be studied scientifically. Was Adam Lanza mentally ill?
There are some instances when mental illness may be associated with serial homicide such as the Son of Sam killer who plied his murderous delusions in NYC during the 1970’s using a Charter Arm’s Bulldog .44 caliber revolver. David Berkowitz used that weapon to kill 6 and wound 7 during his spree. He claimed to have been commanded to kill random couples he saw in cars by a dog he believed possessed by the demon. After spending time in a mental institution following his conviction he was transferred to the state prison at Sing Sing and finally Attica to serve 6 life sentences. When he was on trial Berkowitz plead not guilty by reason of insanity – the delusions he had about communicating with demons. In the end, it was determined that Berkowitz was not mentally ill. The Columbine, CO high school killers, Klebold and Harris were methodical in their planning of the attacks on the school and its students. They built explosive devices and practiced their attack in the weeks before the assault on the school. By outward appearances these two were from middle class families with involved parents.
