Updating a story from earlier this month, a spokesman for the Illinois Department of Corrections says a lockdown at the state’s largest maximum security prison is largely over.  Tom Shaer says Thursday that the entire maximum-security facility at Menard Correctional Center is off all levels of lockdown.  Shaer says a medium-security unit remains on light lockdown for routine maintenance.  Menard was put on lockdown April 4^th following the discovery of a cache of crude weapons and homemade alcohol.  Specifically officials found more than a dozen weapons along with gallons of homemade alcohol and juice and sugar used to make liquor.  The lockdown was instituted so officials could conduct an investigation.
