The newly released documents reveal that nearly a full month before charges were dropped on February 28, the assistant state's attorney on the case told Chicago police detectives that she felt the case would be settled with Smollett paying the city of Chicago $10,000 in restitution and doing community service, which is exactly what happened.Even after that police continued to pursue evidence in the case up to the day the charges were dropped in March.
