Which Agency Holds a Report from Flossmoor
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
Inside Flossmoor that is the agency that reports to the FBI for the city (filed by the FBI as Flossmoor Police Department); outside it, the Cook County Sheriff's Office.
The FBI's agency list also places 14 campus police departments and 15 other agencies in Cook County, each with a records office of its own.
The Elgin Police Department, the Buffalo Grove Police Department, the Deerfield Police Department and eight more are each listed by the FBI across several counties including Cook County, so their arrests are not broken out for Cook County here.
