James Harden said the air just outside the Menard Correctional Center smelled better than the air inside he's been breathing for the last 14 years.
The 36-year-old man was freed from the prison in Chester Friday after a judge vacated his wrongful conviction in the 1991 rape and murder of a young girl. DNA evidence cleared him.
But Harden was still waiting for his brother, 34-year-old Jonathan Barr, to be freed. He remained in custody and the reason wasn't clear.
The men were among five teenagers convicted of killing Cateresa Matthews in a Chicago suburb.
A judge this week vacated the brothers' convictions and that of another man, Robert Taylor, who was released from prison Thursday. The two other men have served their sentences.
