Robert Johnson was 16 years old when he was arrested and sentenced to 80 years in prison. He was let out of the Cook County Jail Thursday evening after his conviction was vacated by a judge.

"My Grandma, she used to always say, 'Well Robert I hope I'm here when you get out,' and I use to always say, 'Grandma don't say that. You going to be here,'" Johnson said. He stayed true to his word.
