Darrius Whitehorn was tossed in the Cook County Jail Aug. 17 after being identified as one Kirk Davis, a robbery suspect from nearby Hammond, Ind., who was using Whitehorn's Social Security number and date of birth.
"It was valuable to see things from the way an inmate sees things," Whitehorn told the Gary (Ind.) Post-Tribune this week as he resumed classes at Loyola University.
Whitehorn, who had never been locked up before, cooled his heels for a week as police in Chicago and Hammond confirmed his true identity.
Whitehorn told the Post-Tribune his fellow inmates left him alone, but he said his court-appointed attorney didn't do much to speed up his release.
"I would not wish this on my worst enemy," Whitehorn said. "I felt I was guilty until proven innocent."
