According to a recent study, mass school shooters typically do not have serious mental health issues. Those who perpetrate mass murder in a school setting while suffering from insanity typically resort to methods other than the use of guns. Consistent with earlier research, over half of school shooting incidents end with the offender committing suicide, and the preponderance of shooters are males and Caucasian.
The majority of mass killers and mass shooters do not suffer from serious mental illness, according to a study conducted by a team from Columbia University Irving Medical Center and the New York State Psychiatric Institute (NYSPI).
Most mass murderers utilized weapons, and semi-automatic or fully-automatic firearms were used more frequently, according to the study led by Ragy R. Girgis, MD, and Gary Brucato, PhD, associate research scientist. When weapons were not involved, stabbings were the most typical form of mass murder at schools.
According to the authors, the study, which was published online on October 27 by the Journal of Forensic Sciences, is the most comprehensive examination of school shootings to date. The study’s data came from the Columbia Mass Murder Database (CMMD), which was created by the COPE group to better understand the correlation between severe mental illness and mass shootings. The CMMD was developed after a thorough analysis of 14,785 cases of homicide reported in English-language media between 1900 and 2019.
Researchers in the study on mass school shootings identified and separated incidents of mass murder that occurred at least in part in educational institutions, classifying them according to their geographic origin (inside or outside the United States) and whether or not weapons were used.
In the 82 cases of mass murder in schools, the following accounted for the most fatalities:
- Almost half (46.6%) occurred in the United States, and the vast majority of gun-related incidents (63.2%) occurred there as well.
- Previous research have shown that white men make up a disproportionate share of mass shooting suspects in school settings (66.7%) and that all mass shooting suspects in schools are male (100%).
- majority of killers did not suffer from a severe mental disorder like psychosis; when existent, psychotic symptoms are more commonly linked to mass murders in educational institutions using methods other than firearms.
- Nearly half of all cases of mass shootings in schools end with the gunman killing themselves.
According to the results, discussions of the risk of mass school shootings that solely focus on mental illness—and particularly psychotic illness—are missing other factors that are linked to the majority of cases and are only adding to the pervasive stigma that already exists around severe mental illness.
The results, the researchers say, will provide insight on the phenomena of mass school shootings and the ways in which they differ from other types of mass murder for policymakers and law enforcement. The researchers also stress that individual behavior is not predictable using these statistics.
