CHICAGO (AP) — Authorities searched Friday for a convicted murderer from Indiana who was mistakenly released after a Chicago court appearance, as officials in Illinois admitted they lost paperwork directing them to return him to Indiana.

It turned out Steven L. Robbins didn't even need to be brought to Chicago in the first place, and Cook County officials on Friday also pointed fingers over who was responsible for that mistake.

Robbins, 44, was serving a 60-year sentence for murder in Indiana and was escorted by Cook County sheriff's deputies to Chicago this week for a court appearance in a separate case involving drug and armed violence charges — a case that had actually been dismissed in 2007.
