Americans awoke Friday to news of yet another mass shooting, this time at a FedEx facility in Indianapolis, where eight people were killed late Thursday.

By the end of the weekend, at least nine more people had died from gun violence in back-to-back shootings across the country -- in Illinois, Texas, Wisconsin, Ohio, Nebraska and Louisiana. At least 10 more were wounded.

Since March 16, when eight people were killed and one wounded in shootings at three Atlanta-area spas, at least 50 mass shootings have been reported in the United States. CNN defines a mass shooting as a shooting with four or more casualties -- dead or wounded -- excluding the shooter.

Some of the shootings this weekend fell short of that definition. But together, they underscored the fact the United States faces not just the Covid-19 pandemic, but a gun violence epidemic, as well.
