ST. LOUIS — Illinois’ biggest maximum-security prison remained on lockdown for a second day Saturday after corrections officers uncovered an inmate cache of more than a dozen crude weapons, gallons of homemade alcohol and hoards of juice and sugar used to make the liquor.

While prisoner resourcefulness in secretly crafting stabbing instruments and booze is an age-old tradition, Friday’s discovery at the Menard Correctional Center southeast of St. Louis reignited debate about crowding at Illinois state lockups.
