More than 180 people were killed in shootings across the country over the Fourth of July holiday weekend, according to data compiled by the Gun Violence Archive and reviewed by NPR.

By 11:30 p.m. on Monday, the Gun Violence Archive reported 189 people killed and 516 injured in shootings over the course of a 72-hour period starting Friday. In total, there were more than 540 shootings over the holiday weekend, the organization reported.

Those numbers may increase as the organization continues to collect statistics from the weekend.

News of major shootings in Chicago, Texas, Virginia and Ohio comes as many of the nation's largest cities are struggling to contain a continued rise in violent crimes. Officials from across the country had spoken of serious fears of a bloody summer earlier this year.

Albany, N.Y., Mayor Kathy M. Sheehan told The Washington Post in May that her city was experiencing a rise in gun violence. At the time she said, "I'm really worried" about the approaching summer months.

Some major cities faced concerns about violent crime last summer similar to what they do this year. In 2020, nearly 90 people were shot in Chicago over Independence Day weekend and 17 of them died.

And in Georgia, Gov. Brian Kemp activated National Guard troops after a spate of shootings and protests in Atlanta. Five people died, including an 8-year-old girl, and at least 30 people were injured during the long holiday weekend last year.
