Fox News political analyst Gianno Caldwell is calling on the FBI to fully take over the investigation into his brother’s murder. 

Caldwell, who lost his 18-year-old younger brother Christian on June 24, 2022, in a random shooting in Chicago, says he will not stop until justice is served.  

"I've received, just this year in March, a call from the Chicago Police Department telling me that there was an arrest, an unrelated case of an individual who they believe with a high likelihood to be involved in the murder of my baby brother, Christian, to be one of the shooters, to be exact," he told "Your World" on Friday. "That same police department also told me that the FBI is investigating this individual, and he's in federal custody, something that I can applaud and appreciate." 

"However, the Chicago Police Department has failed my family since then," he continued. "They absolutely failed us. The detective on the case is not responding to my calls, my text messages and today, I want to use this opportunity and this platform to call for the FBI to fully take over the investigation of my brother's murder." 

CRIME IS SURGING AND HERE’S A WAY TO HELP STOP IT

Caldwell said it has been difficult for his family and he is "greatly disappointed" the Chicago Police Department "continues to fail thousands of families." 

"How can you tell me there's a guy in federal custody right now who you believe there's a high likelihood is responsible for the murder of my brother and there be nothing done since then?," he pleaded. "How can you not call me back? How could that be the case?" 

Caldwell told Fox News he has been working with a congressman to unite lawmakers in asking the FBI to get involved in the investigation and "be a voice for victims all across the country." 

"Now that we have the FBI director coming up before Congress really soon, I'm going to ask those members of Congress, Republicans and Democrats alike,... what is going on with the investigation into the murder of Gianno Caldwell's brother?," he revealed. "I've reached out to the FBI personally multiple times, have not heard anything back from them. So, I want to request for the FBI field office in Chicago, whoever is there, call me. You have my number in your system. If you're in the FBI headquarters in Washington, D,C,. call me. You have my number in your system."

Victims should not be suffering due to soft-on-crime prosecutors not doing their jobs, the analyst reflected.  

"I am pissed the hell off with injustice. I'm pissed the hell off with inaction, and I will not stop until there's justice for my brother."
