If you want to get a real first-hand look at gang culture in Chicago’s South Side, all you need to do is scroll through the Twitter feed of Gahrika Barnes. Barnes tweeted over 27,000 times to her 2,700 followers: boasting about her gang affiliation, posting messages of grief over friends who had been shot by rival gangs and threatening retaliation, and taunting the police. She describes herself in her bio as a “PAID SHOOTA.”

She was murdered on Eberhart Street, mere hours after tweeting the address of her current hangout.
