The death toll from the horrific assault on Robb Elementary School in Uvalde, Texas, on May 24, currently stands at 21, including nineteen children and two adults. But while the loss of life is shocking, the fact that another school shooting took place certainly isn't. Since the April 20, 1999, massacre at Columbine High School, in which two teenage gunmen killed twelve students and a teacher and injured 21 others before committing suicide, incidents like these have become all too common.

According to a mammoth list of such attacks in America, more school shootings have taken place in the 23 years from Columbine to Uvalde than during the entire history of the United States before 1999.

The oldest school shooting in Colorado dates back to 1909, with two more before Columbine; since then, seven have occurred in this state.

Westword published a roundup of school shootings twenty years after the Columbine attack, on April 20, 2019; the country had added another 240 shootings during those two decades. By the time we published an update two years later, on April 20, 2021, there had been another 44 school shootings.

In the succeeding thirteen months, there have been 48 school shootings, including the one in Uvalde, essentially doubling the pace from April 20, 2019, to April 20, 2021, and bringing the total since Columbine to 332. Contrast that with the number of school shootings since the first was recorded on November 12, 1840 — when University of Virginia student Joseph Semmes shot and killed law professor John Anthony Gardner Davis — to the Columbine tragedy almost 160 years later: 320.

The overwhelming majority of school shootings between 1840 and 1999 targeted individuals rather than random groups of students and/or teachers; as a result, the number of casualties in the incidents tended to be small. But that began to change in the twenty years or so before Columbine. In 1986, two people were killed and 74 were injured during a hostage standoff in Cokeville, Wyoming. Two years later, in 1988, a nineteen-year-old murdered two people and wounded nine in Greenwood, California — and in 1989, a racist attack on a school in Stockton, California, killed six and injured 32 more. But almost a decade would pass before the 1998 shooting at a Craighead County, Arkansas, middle school in which five people died and ten were injured — a terrible incident largely forgotten in the wake of the Columbine carnage.

Many of the pre-Columbine incidents in Colorado have been forgotten, too, as more recent tragedies have grabbed headlines. Here are the eleven school shootings in the state, complete with crowd-sourced descriptions.
