Background

The Ionia Correctional Facility (ICF), also known as "I-Max" after its maximum security housing units, is a U.S. state prison located in Ionia, Michigan. The prison was opened in 1987 and consists of five maximum security level V housing units and two medium security level II housing units. It is one of three maximum security men's prison facilities in Michigan, along with Marquette Branch Prison in Marquette, and Baraga Correctional Facility in Baraga. (The Standish Maximum Correctional Facility in Standish was a fifth maximum security men's prison until its closure in 2009 eliminating 604 Level V security beds.) Although the Ionia Correctional Facility was once the state's only supermax prison, Michigan downgraded the facility from a level VI (or supermax) to a level V maximum security prison in 2004. Three of the level V housing units are designated 'general population'.
