The Chicago Tribune reports nearly 1,250 inmates are held beyond their release dates yearly. It mostly affects sex offenders, who face housing restrictions, as well as those subject to electronic monitoring as part of parole.
Corrections officials say this practice, known as a "turnaround," began about a decade ago. They're frustrated by delays, but say they're tied by these restrictions. Critics say the poor are unfairly impacted.
A spokesman for the Illinois Department of Corrections says it costs nearly $22,000 a year to keep an inmate in prison, while parole costs about $2,000.
