Illinois senate Democratic staffers say the maximum-security wing of Stateville prison will remain open.A formal announcement is expected as early as Monday. The state had been planning to close that section of the prison and relocate about 1,600 inmates to other maximum security prisons around the state. Stateville is more than 80 years old. And officials say it's in need of major repair. So far, no one has revealed a plan to pay for needed maintenance at the prison.
