CHICAGO (AP) - An Illinois sheriff says his office takes responsibility for wrongfully releasing a convicted murderer from Indiana who was in Chicago for a court appearance.

Federal and state officials in Illinois and Indiana are on a manhunt for 44-year-old Steven Robbins. He was mistakenly released Wednesday.

Cook County Sheriff Tom Dart says his office lost paperwork in Robbins' file that would have directed jail employees to send him back to Indiana. Robbins was in Cook County on drug and armed violence charges.

Dart said Friday that his office "made mistakes" and will find out exactly what went wrong. He says his office shouldn't have let Robbins go while in its custody.

Dart says officers have been close to recapturing Robbins and there have been sightings of the Gary, Ind., native.
