Cyntoia Brown, who is serving a life sentence for killing a man when she was 16 years old, will make her case for clemency at a hearing in a Tennessee prison today. The state’s Board of Parole will make a recommendation sometime after the hearing. But the decision will ultimately be up to Governor Bill Haslam. Celebrities including Kim Kardashian and singer Rihanna have launched social-media campaigns to free the now 30-year-old woman. Brown’s lawyers have said she was a sex-trafficking victim who killed a man because she feared for her life. Prosecutors said she shot him and robbed him. Brown was tried as an adult and convicted of first-degree murder. She must serve at least 51 years in prison before release.
