SUV Shooting Wounds 12 on Chicago's South Side

An SUV pulled up to a crowd on Chicago's South Side late Friday and two occupants opened fire, wounding at least 12 people, Chicago police said. The eight men and four women ranged in age from 17 to 47. Two men were left in critical condition, one with a gunshot wound to the thigh.

The victims were treated at four hospitals. Another man suffered unknown injuries and refused medical treatment. Police responded to a report of one person shot and found a woman with two gunshot wounds to her back and a man with four graze wounds to his back.

Both were listed in fair condition. At least 21 people have been shot in Chicago since Friday evening, resulting in four deaths, police said. The shootings occurred on Juneteenth. Earlier on Friday, former president Barack Obama and former first lady Michelle Obama welcomed the first visitors to his presidential center on the South Side.

Pastor Donovan Price, a local advocate for gun crime victims, told CBS News that seeing a mass shooting on the holiday is a tragedy. "It should be celebrating," he said. " Detectives were investigating.
