A Columbus woman who pleaded guilty to killing a man in 2005 at a Springfield shopping mall was released from prison Wednesday following an Ohio Supreme Court decision involving one of her co-defendants. 26-year-old Mahogany Patterson was released three years early. She is one of four Columbus women convicted of killing John Deselem as they fled a robbery at a the mall. The conviction of Toneisha Gunnell was overturned by the high court last week. The state says Patterson's conviction has been overturned by an appelate court.
