Decades of deadly gun violence in US schools

An assault-rifle attack at Nashville’s Covenant School that killed three children and three adults is the latest in a relentless cycle of mass shootings at American schools.

Police said they believe the shooter – a 28-year-old Nashville woman armed with at least two assault rifles and a handgun – was a former student at the school. She was shot dead by police.

Here are the deadliest gun massacres of the last 25 years in the United States:

Robb Elementary School – 2022

Nineteen students and two teachers were shot dead on May 24, 2022, when an 18-year-old gunman stormed their Uvalde, Texas elementary school and opened fire.

As families mourned the victims, an uproar swelled over the police response to the worst school shooting in a decade in the US.

It soon emerged more than a dozen officers waited for over an hour outside classrooms where the shooting was taking place and did nothing as children lay dead or dying inside. Officers eventually shot and killed the assailant.

In October, the education board that oversees schools in Uvalde suspended the police force whose bungled response to the mass shooting was widely criticised.

Santa Fe High School – 2018

Ten people, including eight students, were killed when a 17-year-old student armed with a shotgun and a revolver opened fire on his high school classmates in rural Santa Fe, Texas.

Classes had just started on the morning of May 18, 2018, when the shooting began.

Following the tragedy, Texas Governor Greg Abbott unveiled 40 recommendations, mainly focused on increasing armed security on school campuses and stepping up mental health screenings to identify troubled children.

Gun ownership can be a point of pride for many Texans, and even some Santa Fe High School students spoke out against linking the shooting to the need for better gun control.

Marjory Stoneman Douglas High School – 2018

On February 14, 2018, a 19-year-old former student at Marjory Stoneman Douglas High School who was expelled for disciplinary reasons returned to the Parkland, Florida, school and opened fire. He killed 14 students and three adult staff.

Stoneman Douglas students have become outspoken advocates against gun violence under the banner “March for Our Lives”, lobbying for tougher gun control laws and organising protests and rallies.

Their campaign took off on social media, mobilising hundreds of thousands of young Americans – but has so far failed to bring about significant legislative action.

Sandy Hook Elementary School – 2012

A 20-year-old man with a history of mental health issues killed his mother in Newtown, Connecticut, on December 14, 2012, before blasting his way into Sandy Hook Elementary School.

Twenty children, aged six and seven, were shot dead, as well as six adults. The shooter then took his own life.

The parents of Sandy Hook victims have led numerous campaigns to toughen gun control laws, but their efforts have largely failed.

Virginia Tech – 2007

A South Korean student at the Virginia Polytechnic Institute opened fire on the Blacksburg, Virginia, campus on April 16, 2007, killing 32 students and professors before taking his own life. Thirty-three people were wounded.

The gunman apparently idolised the shooters at a 1999 school shooting in Columbine, Colorado, referring to them as “martyrs” in a video, part of a hate-filled manifesto he sent to police during his assault.

Columbine High School – 1999

Two teenagers from Columbine, Colorado, armed with an assortment of weapons and homemade bombs, went on a rampage at their high school.

Twelve students and a teacher were killed during the April 20, 1999, shooting. Another 24 people were wounded.

Columbine, whose name has become synonymous with school shootings, was one of the first – and still counts among the deadliest – such shootings in the United States.
