CHICAGO – The agency tasked with investigating allegations of misconduct on the part of Chicago police is plagued by long delays in case work, some of which have led to the dismissal of charges, according to a published report Sunday.

The Independent Police Review Authority investigates some 2,800 complaints of police misconduct each year. In the five years since it was created by city officials, the agency has filed 40 complaints to the Chicago Police Board, which decides the outcome on serious cases. Those investigations took one to five years to complete, the Chicago Tribune reported Sunday.

The family of Greg Larkins said it was such a delay that cost them justice.
