Which Agency Holds a Report from Wauconda
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
Inside Wauconda that is the agency that reports to the FBI for the city (filed by the FBI as Wauconda Police Department); outside it, the Lake County Sheriff's Office.
The FBI's agency list also places one campus police department and three other agencies in Lake County, each with a records office of its own.
The Barrington Police Department, the Island Lake Police Department, the Fox River Grove Police Department and one more are each listed by the FBI across several counties including Lake County, so their arrests are not broken out for Lake County here.
