HOUSTON - Police have identified 18-year-old Delindsey Mack as the victim of Tuesday's shooting outside Lamar High School.

His family isn't talking on camera, but they said they're afraid of being in the middle of a gang war.

Mack's grandmother Dell Tatum told KHOU 11 News they are all scared of retaliation. She said everyone called him "Poppy." He was set to graduate in December. He had recently transferred from Yates High School to Lamar to escape gang violence.

KHOU 11 News interviewed Mack's mother Dahlia in 2016 at a gang truce summit. In that interview, Mack said, "I'm a mother of a teenage kid. I think I would be devastated if I got that knock on the door or that phone call."

Minister Abdul Haleem Muhammad organized that gang truce event two years ago. He didn't know Mack or his mother, but says this outcome happens all the time in Houston.

"What she joins now is a village of mothers who have lost their children to violence," Muhammad said. "We have killing, retaliation, killing, retaliation, and it keeps going on. What all this proves is it doesn't matter where you move your child. This culture is pervasive in social media. We won't solve it until we come together as a community."
