Generation Columbine: Emerging Statistical Warning Signs of Recent U.S. Mass Shooters/Bombers

The WVPI's platform is that mass violence can be predicted and thus prevented. We have over the years offered research identifying the warning signs.


A new statistic is now emerging based on the perpetrator's gender and age: Males from 15-26 years old with the deadly "Columbine effect" continuing.



The deadliest attacks on American soil has been perpetrated by males under the age of 26:


  1. Robb Elementary School, Uvalde, Texas on May 24, 2022 leaving 19 students and two teachers dead. The perpetrator who was killed by law enforcement was a male who just turned 18 mere days before the attack.

  2. Tops Friendly Market Store, Buffalo, New York on May 14, 2022 leaving ten people dead and three wounded. The suspect an 18-year-old male was arrested on scene and is awaiting trial for murder.

  3. King's Soopers Market, Boulder, Colorado on March 22, 2021 leaving ten people dead. The suspected perpetrator, was a 21-year-old male, has been deemed incompetent to stand trial.

  4. Walmart, El Paso, Texas on August 3, 2019, killing 23 people and wounding 23 others. The perpetrator, who is awaiting trial, was a 21-year-old male.

  5. Santa Fe High School, Santa Fe Texas on May 18, 2018 leaving eight students and two teachers dead and 17 others wounded. The confessed shooter/bomber, the first school shooter in United States history to be charged with federal crimes, is a 17-year-old male. He has been deemed incompetent to stand trial.

  6. Marjory Stoneman Douglas High School, Parkland, Florida on February 14, 2018 leaving 17 people dead including three faculty members and 17 others wounded. The perpetrator was 19 years old at the time. In 2021, he pled guilty to 17 counts of murder and 17 counts of attempted murder, and is awaiting a trial on sentencing to learn if he will receive life in prison or the death penalty.

  7. Sutherland Springs Church church in New Brunfels, Texas on November 5, 2017, leaving 26 people dead, including an unborn child, and 22 others wounded. The perpetrator, a 26-year-old male, killed himself after leaving the scene of the attack.


All of the above studied prior assaults and emulated or learned from them, particularly the April 20, 1999 attack at Columbine High School leaving 13 dead, perpetrated by a student aged 17 and a fellow student aged 18, both of whom were seniors slated to graduate weeks later.


The Parkland shooter conducted research on Columbine. The Santa Fe High School confessed shooter/bomber dressed as the Columbine killers. The Sutherland Springs killer was said to have a "Columbine feel to him" while he was in high school.


We have provided extensive research on "Generation Columbine" on this website. It is intended to assist in identifying the warning signs necessary to prevent the next attack from happening.
