Fox News political analyst Gianno Caldwell, who has often spoken out about gun violence in Chicago, announced on Saturday (June 25) that his younger brother was fatally shot.

“Yesterday was the worst day of my existence. I received a call informing me that my teenage baby brother was murdered on the south side of Chicago,” Caldwell tweeted. “Never could I have imagined my baby brother’s life would be stolen from him. Please keep my family in your prayers.”

Chicago police said the shooting happened around 2 a.m. in the city’s Morgan Park neighborhood, ABC Chicago reported. A suspect fired at a group of people before fleeing in a black sedan, killing two of them and critically wounding a third victim.

Over the weekend, gun violence killed a total of three people and injured 12 others across the city, NBC Chicago reported. A 5-month-old girl was among those who died. The infant was shot in the head while inside a vehicle and pronounced dead at Comer Children’s Hospital.

Caldwell, a Chicago native who joined Fox News in 2017, was a panelist June 5 on FOX’s “The Big Sunday Show” and called on progressive district attorneys to end their “soft-on-crime” policies, FOX News reported.

"If you're going to have these soft-on-crime measures, you're never going to get the crime problem under control, whether it be in Chicago, whether it be in Philadelphia, Detroit, wherever it may be," he said.

"These policies must change, and they got to get tough and they got to get tough immediately, otherwise we're going to see more and more people dying in the streets daily."
