A month has passed since Fox News analyst Gianno Caldwell’s 18-year-old brother, Christian, was fatally shot in Chicago on June 24, yet there have been no arrests or other developments in the case since his death.

Now, Cook County Crime Stoppers is offering a $15,000 reward for information leading to the arrest of the suspect or suspects involved in the shooting that left Christian dead and two other victims injured on the 11400 block of South Vincennes Avenue.

The other victims, a 31-year-old man and a 25-year-old woman, were unknown to Christian, who was out with friends at the time.

“We’re pleading for any individual who may know something or think they know something to come forward,” Caldwell told Fox News Digital. “There’s now reward money being offered, and [tips] will stay confidential. We just want to get justice for Christian. Our family is pleading for justice.

“We just believe in God that there will be justice.”

Caldwell said he is both appreciative when police call him with updates and frustrated when they don’t pick up the phone, as the last month has presented a combination of both silence and communication from the Chicago Police Department (CPD).

“I’ve had some good communication with them, and I’ve had some silence from the Chicago Police Department,” he said. “And I just want those officers — those detectives that are working on this case — to not be desensitized by the heinous crimes that they continue to get piled on their desks day after day. I just want to ensure that there’s justice for my brother Christian, but also [for the] many, many victims that are being killed on a day-to-day basis in Chicago.”

The fact that the suspect or suspects who killed Christian are still out there could mean more violence against other innocent victims.

“We need to start talking with the police and working with them, because statistically … the increase of violence could touch many, many other families, especially if there’s not a coalition of peace,” Caldwell said. He added that Chicagoans need CPD’s trust to willingly give them confidential information to “ensure that someone else’s life can be saved.”

Christian was remembered for his smile, his love of friends and family and his interest in sports, video games and music. 

Caldwell and his brother were two of nine siblings who grew up poor in Chicago. Caldwell has repeatedly criticized the city’s “soft-on-crime” policies that allow repeat offenders back on the streets. Born in 2004, Christian was the youngest of the nine siblings and had just turned 18 this year. 

Caldwell previously told Fox News Digital that Christian and his other younger brothers are more like his sons since Caldwell is the father figure in their lives.

Christian was buried in Oak Park Cemetery in Forest Park July 9.

While 800 victims were killed in Chicago in 2021, marking the most people murdered in The Windy City in a single year over a quarter century, half of those homicide investigations considered “solved” by CPD actually resulted in charges filed against suspects, FOX 32 Chicago reported in April.
