At least 17 people were killed from Friday to Sunday in mass shootings, the deadliest weekend of mass shooting gun violence so far this year, according to a USA TODAY analysis.

In Philadelphia; Chattanooga, Tennessee; Saginaw, Michigan; Omaha, Nebraska; and other towns and cities across the United States, there were at least a dozen shootings with four or more people injured or killed by gunfire, according to data compiled by the Gun Violence Archive and analyzed by USA TODAY. At least 82 people were wounded or killed in mass shootings from Friday to Sunday, the analysis found.

“America’s gun violence crisis was on full display this weekend, an emergency crying out for a solution that we know exists,” said Kris Brown, president of Brady, a gun violence prevention group.

The next worst weekend for mass shooting deaths so far this year occurred from May 13 to 15 – when 14 people were killed in mass shootings, including 10 at a Buffalo, New York, grocery store, according to the analysis of Gun Violence Archive data. Fourteen people were also killed in mass shootings during the weekend of Dec. 31, 2021, to Jan. 2.

There have been at least 245 mass shootings this year, according to the archive. Last year, there were 692 mass shootings, the highest number of mass shootings of any year since 2014.

This same weekend last year, June 4 to 6, seven people were killed and 53 wounded in mass shootings, according to Gun Violence Archive data. In 2020, the first weekend of June saw six mass shooting deaths and 50 people wounded, the archive’s data shows.

A mass shooting listed in the Gun Violence Archive’s data as occurring Saturday could not be independently verified by USA TODAY or in other news reports and was not included in the analysis. No fatalities were reported in the archive’s listing of that shooting. Shootings that involved fewer than four or more people shot or killed did not meet the archive’s definition of a mass shooting and were not included.
