Mass shooting Chicago: Drive-by shooters injure at least 12 people in Princeton Park, Chicago shooting near 95th and Princeton

At least 13 people were shot and another person was also injured as a pair of drive-by shooters opened fire late Friday evening on the city's South Side, Chicago police and neighbors said.

The mass shooting happened during a Juneteenth celebration, neighbors told ABC7.

Police responded to a call about shooting near West 95th Street and South Princeton Avenue in the city's Princeton Park neighborhood, in the Roseland area, just after 11 p.m.

Investigators believe a red SUV pulled up alongside a large crowd, and two people inside the vehicle fired shots before fleeing the scene.

Surveillance video captured what appears to be a barrage of gunfire, followed by people running for cover.

Responding officers found two people who had been shot. A 32-year-old woman, shot twice in the back, was transported to Christ Hospital in good condition. A 44-year-old man, grazed in the back four times, was taken to the University of Chicago Medical Center in good condition.

Police said 11 other people took themselves to local hospitals.

Police provided an update on the shooting Monday, saying another woman, 19, had been shot in the buttocks and self-transported to the University of Chicago Medical Center in good condition.

Neighbor Michael Blount said he heard rapid gunfire from his home.

"All of a sudden you this loud, bah, bah bah, bah," Blount said. "I could hear rapid gunfire, I'm like it can't be. Next thing I know I heard the sirens."

Blount expressed disappointment that the violence occurred during what was meant to be a celebration.

"It was a shame that it happened on Juneteenth. I'm very sorry to see that. That's what it was supposed to be about. Celebration, not what just happened. That was purely wrong," he said.

A motive for the shooting remains unclear, and no arrests have been announced.

Ald. Anthony A. Beale issued a statement, saying, "I am heartbroken by the senseless shooting in the Princeton Park neighborhood that left so many people injured and so many families terrified and hurting. In a matter of seconds, an ordinary summer night was shattered by gunfire. Lives were upended, families were thrown into fear, and an entire community was reminded how quickly violence can change everything. No one should have to wonder if they or someone they love will make it home safely. This is the cruel reality of the mindless menace of gun violence in our city. It does not just wound those caught in its crossfire; it steals a measure of joy from every block it touches and chips away at the sense of security that binds communities together. Today, my thoughts are with the victims and their families, and I stand shoulder to shoulder with our residents as they face the difficult days ahead. Our community is hurting, but we will not surrender to fear. We will grieve with the victims, stand with their families, and hold fast to the belief that violence does not get the final word-whether in Princeton Park or anywhere in Chicago."

Mayor Brandon Johnson said his administration is focused on addressing gun violence.

"Know that my admin. is working overtime not only to hold people accountable to remove illegal guns off the streets of Chicago," Johnson said.

Area Two detectives are investigating. Chicago police did not immediately provide further information about the shooting.
