Officials say they've found a gun inside the walls at Pontiac Correctional Center. The unloaded gun was reportedly smuggled into the prison about 17 years ago. A DOC Spokesman says they got a tip back in 1996 and have been looking for the weapon in several remote areas since then. It was another tip that led investigators to look inside the walls last Friday. The gun was discovered in an area that isn't accessible to inmates and apparently, the gun didn't compromise the sagety of anyone inside the facility.
