For Delmonte Johnson, the violence he wanted to eradicate from the city of Chicago.

Johnson, 19, was shot in the chest and stomach before being taken to the hospital, where he later died Wednesday, TV station WLS reported. The teen worked with youth advocacy group GoodKids MadCity, which was formed after a high school in Parkland, Florida.

Johnson's brother Devirgo Johnson said Delronte was playing basketball after dropping another sibling off at practice, the Chicago Sun Times reported.

"" I laid it down to my brother when he was dying in my hands, "said Devirgo, according to the paper. "I knew he was leaving me, but he's still with me."

Chicago police reported Thursday, the Sun Times reported.

At a vigil, Johnson's mother Onique Walker spoke about her son's activist work and passion for sports. She said to be a Christian youth fundraiser.

"I'm going to miss my baby," she said. "Anything you asked Delmonte to do, Delmonte was there."

GoodKids MadCity co-founder Carlil Pittman told the Sun Times he knew Johnson through their church and that Johnson later joined the anti-gun violence group.

David Hogg, a survivor of the Parkland shooting and anti-gun violence activist, tweeted his sympathy for Johnson's family.

"My heart goes out to Delmonte and his family," Hogg tweeted. "Together we will end this."
