Thirty people were shot in just 3 hours early Sunday in Chicago, with five mass shootings of three or more victims accounting for 25 of the casualties, according to the Chicago Sun-Times.

Two people were killed and 28 were wounded between midnight and 3 a.m., including at least 12 teenagers, one of whom was shot in the head and killed, the Sun-Times reported.

The shooting with the most victims left eight people wounded in a South Side neighborhood after a group of men walked up to the eight people standing in a courtyard and opened fire, the Sun-Times reported.

Four of the victims were teenage girls. They’re all expected to survive.

Fewer than two hours later, six more people were shot, including five teenagers, when two men walked up to a group of people on a sidewalk in a Southwest Side neighborhood and started shooting, the Sun-Times reported.

A 17-year-old girl was shot in the face and killed, and four more teenagers, with ages ranging from 11 to 17, were wounded, the Sun-Times reported.

Four more people were shot in a separate shooting at a block party in the same neighborhood of Lawndale just a few hours earlier, the Sun-Times reported. Three of the victims were teenagers, with the youngest being just 13 years old.

Dozens of people were seen outside one of Stroger Hospital, one of Chicago’s busiest trauma centers, on Sunday morning crying and grieving, the Sun-Times later reported.

“This is the worst I’ve ever seen it,” one officer outside Stroger told the Sun-Times. “It’s hot right now. There’s a lot of tension … And it might get worse because you can hear people talking about revenge, saying on their cell phones ‘I know know who did it. You get him.'”

This is Sunday, August 5, 2018.

This is in Chicago, hours following multiple mass shootings in the city. Families in mourning, away from their hurt. Why? The entire hospital is said to be on lockdown.
