We're coming off another weekend of deadly mass shootings across the country.

In the past 72 hours, at least 17 people have been killed. Nearly 70 were hurt, and several of those victims have critical injuries.

According to data from the Gun Violence Arch archive, there were at least 13 mass

shootings from Friday through Sunday. The Independent Research Group defines a mass shooting as an

incident in which four or more people are shot, not including the shooter. Two cities saw the

worst of the violence. In Philadelphia, three people died and 12 were wounded late Saturday night in a popular downtown district, South Street.

Investigators believe the shooting came after a fight between two men, and most of the victims, innocent bystanders.

Police say officers found shell casings from five different guns at the scene.

So far, no arrests. Meanwhile, in Chattanooga, Tennessee, two people were shot and killed and 12 injured

early Sunday morning. One person died after they were being hit, after they were hit by a car while trying to flee.

This was Chattanooga's second weekend in a row of mass shooter violence.
