When StoryCorps visited Danville Correctional Center in Illinois, one of the inmates who told his story was Carlos Rocha.

Carlos grew up in Chicago, and he, like his brothers, joined a gang. In 1998, he was arrested for weapons possession. Just before he was to be released on bond, Carlos got into a fight with another inmate and killed him. He was sentenced to 24 more years behind bars.
