It follows a lull in mass killings during the pandemic in 2020, which had the smallest number of such attacks in more than a decade, according to a database compiled by The Associated Press, USA Today and Northeastern University. That database tracks mass killings defined as four or more dead, not including the shooter.

The USA TODAY/AP/Northeastern University mass killings database has tracked a dozen mass killings in 2021 that have left 68 people dead and 15 people injured. Three of those events happened in just one week.

Co-led by David Lazer, a political scientist at Northeastern University in Boston, Massachusetts, researchers have been conducting surveys of as many as 25,000 people per month, across all 50 US states, as well as collecting information on Twitter use by nearly 1.6 million people.

“What drives the overall suicide rate in the U.S. is gun ownership in the home,” said Matthew Miller, a professor of health sciences and epidemiology at Northeastern University, who has studied the intersection of guns and suicide. “It’s much easier to die when you can reach for a gun than when you can’t.”
