Most students who committed deadly school attacks over the past decade were badly bullied, had a history of disciplinary trouble and their behavior concerned others but was never reported, according to a U.S. Secret Service study released Thursday.
In at least four cases, attackers wanted to emulate other school shootings, including those at Columbine High School in Colorado, Virginia Tech University and Sandy Hook Elementary School in Connecticut. The research was launched following the shooting at Marjory Stoneman Douglas High School.
The study by the Secret Service’s National Threat Assessment Center is the most comprehensive review of school attacks since the Columbine shootings in 1999. The report looked in-depth at 41 school attacks from 2008 through 2017, and researchers had unprecedented access to a trove of sensitive data from law enforcement including police reports, investigative files and nonpublic records.
The information gleaned through the research will help train school officials and law enforcement on how to better identify students who may be planning an attack and how to stop them before they strike.
“These are not sudden, impulsive acts where a student suddenly gets disgruntled,” Lina Alathari, the center’s head, said in an Associated Press interview. “The majority of these incidents are preventable.”
The fathers of three students killed in 2018 at Marjory Stoneman Douglas High School in Parkland attended a media conference Thursday in support of the study.
Tony Montalto, whose daughter, Gina Rose Montalto, died, said the research was invaluable and could have helped their school prevent the attack.
“My lovely daughter might still be here today,” he said. “Our entire community would be whole instead of forever shaken.”
Montalto urged other schools to pay attention to the research.
"Please, learn from our experience," he said. "It happened to us, and it could happen to your community, too."
Nearly 40 training sessions for groups of up to 2,000 people are scheduled. Alathari and her team trained about 7,500 people during 2018. The training is free.
The Secret Service is best known for its mission to protect the president. The threat assessment center was developed to study how other kinds of attacks could be prevented. Officials use that knowledge and apply it in other situations, such as school shootings or mass attacks.
Since the Columbine attack, there have been scores of school shootings. Some, like Sandy Hook in 2012, were committed by nonstudents. There were others in which no one was injured. Those were not included in the study.
The report covers 41 school attacks from 2008 through 2017 at K-12 schools. They were chosen if the attacker was a current or recent former student within the past year who used a weapon to injure or kill at least one person at the school while targeting others.
"We focus on the target so that we can prevent it in the future," Alathari said.
Nineteen people were killed and 79 were injured in the attacks they studied; victims included students, staff and law enforcement.
The Secret Service put out a best practices guide last July based on some of the research to 40,000 schools nationwide, but the new report is a comprehensive look at the attacks.
The shootings happened quickly and were usually over within a minute or less. Law enforcement rarely arrived before an attack was over. Attacks generally started during school hours and occurred in one location, such as a cafeteria, bathroom or classroom.
Most attackers were male; seven were female. Researchers said 63% of the attackers were white, 15% were black, 5% Hispanic, 2% were American Indian or Alaska Native, 10% were of two or more races, and 5% were undetermined.
The weapons used were mostly guns, but knives were used, as well. One attacker used a World War II-era bayonet. Most of the weapons came from the attackers' homes, the investigators reported.
Alathari said investigators were able to examine detailed information about attackers, including their home lives, suspension records and past behaviors.
There's no clear profile of a school attacker, but some details stand out: Many were absent from school before the attack, often through a school suspension; they were treated poorly by their peers in person, not just online; they felt mistreated; some sought fame, while others were suicidal. They fixated on violence and watched it online, played games featuring it or read about it in books.
The key is knowing what to look for, recognizing the patterns and intervening early to try to stop someone from pursuing violence.
"It really is about a constellation of behaviors and factors," Alathari said.
The attackers ranged in age but were mostly young adults, seventh-graders to seniors. More than three-quarters initiated their attack after an incident with someone at school.
In one case, a 14-year-old shot a classmate at his middle school after he'd been mocked and called homophobic names. The attacker later reported the victim made comments that made him uncomfortable, and they were the final straw in his decision to attack. Seven attackers documented their plans, and five researched their targets before the attack.
Thirty-two were criminally charged, with 22 charged as adults. Most took plea deals. More than half are incarcerated. A dozen more were treated as juveniles. Seven killed themselves, and two were fatally wounded.
Alathari said the report shows that schools may need to think differently about school discipline and intervention.
The report does not weigh in on political topics such as whether guns are too accessible or whether teachers should be armed.
She said their goal is to make schools a safer place where no more attacks occur.
