A weekend birthday party in Stockton, California turned tragic when gunfire left three children and one adult dead.

Burna Boy is offering to pay the funeral expenses for the four victims who lost their lives in a mass shooting in Stockton, California last weekend. In a statement shared with The Source, the artist explained that he learned about the tragedy while tuning in to The Breakfast Club and immediately felt moved to step in.

“When I heard about the children murdered in Stockton, my heart broke,” he said. “After hearing the story on The Breakfast Club, I reached out to Wack 100 and connected with Jason Lee because no family should ever face this kind of pain alone. I wanted to do whatever I could to support these parents as they begin the long process of healing.”

The shooting happened during a toddler’s birthday celebration and took the lives of three children, ages 8, 9 and 14, along with a 21 year old. Investigators believe the shooters may have been targeting MBNel and Fly Boy Doughy, who were both in attendance, according to The New York Post.

Stockton Mayor Christina Fugazi addressed the tragedy on Sunday and attributed it to gang violence. “And let us call this what it is. Gang violence exists in cities across the country, but this act was a pure act of terrorism. A complete, cowardly Terrorist Act! The person or people responsible will lose their freedom for life,” Fugazi said in remarks obtained by KCRA. “But they also handed out a life sentence to their own families and to the people who may have loved them. Because once they are arrested, they will NEVER see the light of day again!”

Although Fugazi did not mention any specific gangs, she urged anyone with information to come forward. Officials have already offered a reward of up to fifty thousand dollars for tips that lead to an arrest. Police have not announced any suspects and the investigation is ongoing.

Jason Lee, known for his work with Hollywood Unlocked, is currently serving as the Vice Mayor of Stockton. While speaking with journalists and local residents earlier this week, Lee said it has “never been gangster to kill kids.”
