“Be careful” were the last words Shenee Johnson spoke to her 17-year-old son Kedrick, who was two weeks away from graduating from high school with a college scholarship when he was shot in the chest at a 2010 party.
“When the doctor came out at the hospital, I saw the look on his face, and I knew,” Johnson, 45, tells PEOPLE in this week’s issue. “I was like, ‘This just can’t be life. I refuse to accept this.’ ”
Reeling from her grief, Johnson — who is amongPEOPLE’s 25 Women Changing the World— began to get involved with gun violence prevention in her Queens, N.Y. community.

“I started meeting other mothers like me, and their stories sounded the same: 17, 16-year-old young people being murdered. And I knew then that I would dedicate my life to preventing gun violence.”

“As a mother of Black boys, the risk of gun violence to my kids was always in the back of my mind,” says Johnson. “That’s why I was hard on Kedrick and never wanted to let him out of my sight.”
A vivacious kid with an outsized personality, Kedrick had big dreams from a young age. “We were driving on the highway, and I was like, ‘Kedrick, what do you want to be when you grow up?’ ” recalls Johnson. “And he said, ‘Well, I could take President Bill Clinton’s job. It would be hard, but I could do it.’ I mean at four — and I have witnesses! That was Kedrick.”

Today, Johnson uses her platform with Moms Demand Action to speak out for common-sense gun laws, such as universal background checks.
“A lot of people feel like we want to take away their Second Amendment rights, and that’s not the case,” she says. “If you have guns, be responsible with them — that’s all we’re saying. And we have to learn to put people over profits.”
At the heart of her work, of course, is Kedrick — who had earned an academic scholarship for college but wanted to pursue a music career.
“When I finally listened to his music, I was like, ‘Oh, my God Kedrick, you are talented!’ ” recalls his mom. “And he looked at me and said, ‘Yes, Ma, the world is going to know my name.’
“I will never forget that sentence. In some weird way, I’m going to make that happen for him. People will know Kedrick’s name.”
