SPRINGFIELD, Ill. (AP) — An analysis shows there are nearly two dozen inmates who escaped from Illinois prisons or halfway houses over the years and haven’t been caught.

The Associated Press collected and analyzed prison data for the number of escaped inmates. It also found 11 who were on the lam have been snared in the past two years. Three died while on the loose.

The Illinois Department of Corrections says it never stops looking for them or closes a case.

Apprehension specialist Mike Harrington says he hunts fugitives by contacting family and trying to determine patterns and practices.

Most inmates listed as escaped fled from transition centers, not from prison lockups.

One inmate escaped in 1955 and hasn’t been seen since.
