Ex-inmate Cyntoia Brown-Long explores patterns of sexual and drug abuse in new memoir

Cyntoia Brown-Long, now 31 years old, knows as much about life in prison as she does about being free. At 16, she was arrested for robbing and killing a man she says picked her up for sex and later was sentenced to life in prison. But two months ago, Brown-Long walked out of a Tennessee prison after successfully petitioning the governor for clemency.
