Illinois Department of Corrections officials are investigating a prison power outage to decide whether the state’s correctional facilities are adequately prepared for emergencies.
A storm on Aug. 20 caused a 92-minute blackout at Vandalia Correctional Center. One prisoner at the maximum-security facility attacked a guard and others became unruly.
Other prison power outages caused similar upheaval of inmates, at Vienna Correctional Center in January and East Moline Correction Center in 2012.
