A manhunt began yesterday in Chicago after Garrett Glover, an accused killer, was mistakenly released from custody. The 29-year-old should have been held on a $2 million bond.

Cook County officials are still trying to figure out how the screw-up went down. Glover is considered dangerous and is accused in a 2012 shooting on the Dan Ryan Expressway that resulted in the death of Larry Porter.

For the past two years Glover was held at the Cook County Jail on separate armed robbery charges. After being charged for armed robbery last Thursday, he was transported to Stateville prison in Joliet. Authorities there determined he had served enough time to be eligible for parole and was released.

Authorities reminded the public that aiding a fugitive is a felony, punishable by 1-3 years in prison.

Anyone with information about Glover's whereabouts should immediately contact the Cook County Sheriff's Command Center at 773-674-0169.
