CHARLESTON, Mo. (AP) — Cornealious “Mike” Anderson spent 13 years free from prison due to a clerical error, then nearly a year behind bars when the mistake was caught. On Monday, he walked out of a southeast Missouri courtroom a free man again — this time with no need to look over his shoulder. Mississippi County Associate Circuit Judge Terry Lynn Brown needed just a 10-minute hearing before ruling that he was giving Anderson credit for time served for all 4,794 days between his conviction and when he was arrested last year.
