He did pledge to review procedures in his office, including at the warrant unit. In particular, Dart said he wanted to learn why that unit decided to act on Robbins' drugs and armed violence warrant when he was already serving a long murder sentence.
Robbins, a Gary, Ind., native, was serving a sentence for murder and weapons convictions out of Marion County in Indiana.
Witnesses to the 2002 killing told police Robbins was arguing with his wife outside a birthday party in Indianapolis when a man intervened, telling Robbins he should not hit a woman, according to court documents.
Witnesses said Robbins then retrieved a gun from a car and shot the man in the chest. He started serving his sentence in October 2004.
At a brief appearance Saturday in Chicago bond court, a public defender told the judge Robbins had no intention to flee.
Assistant Public Defender Todd Chatman noted Robbins was released by the state and said he was not at fault. The judge dropped an escape charge.
Robbins was then driven about 50 miles east to the Indiana State Prison.
"We are grateful that law enforcement caught him before he committed another crime," Indiana Department of Corrections spokesman Doug Garrison said.
It is not the first time a prisoner has been mistakenly freed from the Cook County Jail. In 2009, Jonathan Cooper, who was serving a 30-year manslaughter sentence in Mississippi, was brought to Chicago to face charges that he failed to register as a sex offender.
Prosecutors dropped the charges because, as an inmate, he could not comply with the Sex Offender Registration Act. A clerk reportedly failed to include the Mississippi sentence information in Cooper's file, and jail staff released him.
Cooper turned himself in several days later.
