In 2008, Rene Lima-Marin walked out of a Colorado prison after serving 10 years in prison of what he thought was a 16-year sentence for robbery. In the years that followed, he served what he was told were his five years of probation without incident. In fact, he got married, started a family, joined a church, got a steady job and seemed to have turned his life around. Then, last year he got a phone call from the Denver public defender's office. His release had been a big mistake. He still had 88 years left on his sentence. He's back in prison now and not eligible for parole until 2054.
