The Secret Service released a profile Thursday that shared overlapping personality and physical characteristics of the 28 people who carried out “mass attacks” in public places in the United States in 2017, including the finding that all were male.
The average age of the 28 assailants was 37, and all attackers fell between 15 years old and 66 years old, the Secret Service National Threat Assessment Center’s Mass Attacks in Public Spaces report concluded.
Seven-in-10 had a history of criminal charges, while one-third had been involved in domestic violence incidents. Nearly two-thirds had a general violence history and the same amount had symptoms of mental health illnesses.
Nearly half were motivated to carry out the attacks due to a personal grievance related to his workplace, home or other issue.
The majority – 54 percent – used illicit drugs or abused substances like alcohol.
All 28 men reported at least one significant stressor in the past five years and more than half appeared to have gone through financial issues during that half-decade time span.
More than four-in-five attackers displayed behavior that the Secret Service said indicated signs of aggressive narcissism, including rigidness, hostility, or extreme self-centeredness. Nearly the same amount had threatened or communicating in a way that communicated others.
Exactly 82 percent of the attacks involved a firearm. Three-in-five of all incidents took place between 7 a.m. and 3 p.m. There was no day of the week an incident did not happen.
A total of 147 people were killed and almost 700 others were wounded as a result of these 28 attacks.
