A Partial List of Mass Shootings in the United States in 2022

The deadliest mass shooting in the country so far this year was the massacre in which 19 children and two teachers were killed at an elementary school in Uvalde, Texas, on May 24. It happened 10 days after 10 people were shot and killed in a supermarket in Buffalo, New York.

There is no consensus on what constitutes a mass shooting, complicating the efforts of government, nonprofits and news organizations to document the scope of the problem. Different groups define mass shootings differently, depending on circumstances including the number of victims, whether the victims are killed or wounded, and whether the shooting occurs in a public place. The Gun Violence Archive, a nonprofit research group that tracks gun violence using police reports, news coverage and other public sources, defines a mass shooting as one in which at least four people were killed or injured.

The Gun Violence Archive has counted at least 606 mass shootings so far this year, through mid-November. Of those shootings, 20 involved five or more fatalities, including the attack at a Walmart in Chesapeake, Virginia, on Tuesday and the shooting at an LGBTQ nightclub in Colorado Springs, Colorado, on Saturday that left at least five people dead.

The group recorded 692 mass shootings last year, with 28 involving four or more fatalities.

Here is a partial list of mass shootings so far this year.

Nov. 22: Chesapeake, Virginia

A longtime store manager at a Walmart opened fire in a break room as the store was preparing to close for the night, killing six people, authorities said. The gunman was found dead, apparently from a self-inflicted gunshot wound, according to police.

Nov. 20: Colorado Springs, Colorado

At least five people were killed and 18 injured in a shooting at an LGBTQ nightclub. The gunman was injured and taken to a hospital.

Nov. 13: Charlottesville, Virginia

Three University of Virginia students, all of whom were players on the football team, were killed and two were wounded when a gunman, a former football player, opened fire in a garage after a field trip to see a play in Washington.

Oct. 13: Raleigh, North Carolina

A gunman, described by authorities only as a “white male juvenile,” killed at least five people, including an off-duty police officer. The attacks drew a large response from law enforcement agencies to the residential area near the Neuse River Greenway, a popular bike trail for Raleigh residents.

Sept. 7: Memphis, Tennessee

Memphis was effectively closed down during an hourslong search for a 19-year-old gunman who killed four people while streaming some of the violence on Facebook Live. There were several shootings and carjackings over the course of the day.

July 17: Greenwood, Indiana

A 20-year-old gunman opened fire in the food court of a mall, killing three people and wounding two others. Minutes into the attack, the gunman, identified as Jonathan Douglas Sapirman, was fatally shot by a bystander.

July 4: Highland Park, Illinois

Robert E. Crimo III, 21, was taken into custody several hours after the shooting in Highland Park, a suburb north of Chicago, and charged with seven counts of first-degree murder. Seven people were killed, and dozens more, ranging in age between 8 and 85, were wounded.

Police said the gunman had climbed onto a rooftop with a rifle and begun firing into a crowd gathered for a Fourth of July parade.

June 30: Newark, New Jersey

Nine people were shot and wounded in what police said appeared to be an incident related to a stolen car. The youngest victim was 17, and the oldest was 68. All were treated at local hospitals.

June 20: Harlem neighborhood of New York City

A 21-year-old college basketball player was killed and eight people were wounded in an early-morning shooting at a popular picnicking area.

After surging during the pandemic, the rate of shootings in New York has begun to fall, although it is still above pre-pandemic levels.

June 4: Philadelphia

Three people were killed and 12 injured in a shooting in downtown Philadelphia, police said. An officer fired at one of the gunmen, police said, but it was unclear whether the gunman had been hit.

Another six people were killed and dozens were injured in several other shootings over the same weekend, including in Arizona, South Carolina, Tennessee and Virginia.

June 1: Tulsa, Oklahoma

Several people were shot and five were killed at a medical building next to Saint Francis Hospital in Tulsa, Oklahoma, Tulsa police said. Police said the gunman was believed to have killed himself.

May 24: Uvalde, Texas

A gunman killed 19 children and two teachers at Robb Elementary School in Uvalde, Texas, about 80 miles west of San Antonio.

Law enforcement officers fatally shot the gunman, identified as Salvador Ramos, 18, but not until well over an hour after he walked into the school, raising questions about whether lives could have been saved if they had acted sooner.

May 15: Laguna Woods, California

A gunman killed one person and critically wounded four other members of the Irvine Taiwanese Presbyterian Church in Laguna Woods. The congregation, which holds services at the Geneva Presbyterian Church, overpowered the gunman and hogtied him, preventing further bloodshed, authorities said.

The suspect, David Chou, 68, is a Las Vegas man with a wife and child in Taiwan who had traveled to Orange County with a grievance against Taiwanese people, authorities said. He was charged with murder and five counts of attempted murder in what the Orange County sheriff, Don Barnes, called a “politically motivated hate incident.”

May 14: Buffalo, New York

A gunman armed with an assault-style weapon killed 10 people and wounded three others at a Tops supermarket in a predominantly Black section of Buffalo, authorities said.

The suspect, Payton S. Gendron, 18, is white, and the 10 people who died were all Black. Before the attack, Gendron had posted a nearly 200-page racist screed online. He was indicted on 25 counts, including 10 counts of first-degree murder and 10 counts of second-degree murder charges as hate crimes, as well as a single count of domestic terrorism motivated by hate.

May 13: Milwaukee

At least 16 people were wounded by gunfire in a shooting in downtown Milwaukee, in a popular nightlife area blocks from the arena where an NBA playoff game ended hours earlier, authorities said.

April 12: Brooklyn borough of New York City

A gunman opened fire inside a crowded subway car during the morning rush, wounding 10 people, the worst attack on New York City’s subway system in decades. More than a dozen other people were also injured, with some choking on smoke from the two devices police said the gunman detonated before he started shooting. No one was killed.

A suspect, Frank R. James, was arrested the next day and charged with carrying out a terrorist attack on a mass transit system. If convicted, he could face life in prison.

April 3: Sacramento, California

As revelers spilled out of nightclubs in a two-square-block area of downtown Sacramento, a barrage of gunfire killed six people and wounded 12, authorities said. Days later, the Sacramento Police Department said “gang violence” was at the center of the shooting, which involved at least five gunmen.
