Which Agency Holds a Report from Cahokia Heights
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 Cahokia Heights that is the agency that reports to the FBI for the city (filed by the FBI as Cahokia Heights Police Department); outside it, the St. Clair County Sheriff's Office.
The FBI's list also carries Alton and Southern Railway and Union Pacific Railroad in St. Clair County (other agency) and Southwestern Illinois College (campus police), each with a records office of its own.
The Columbia Police Department, the New Baden Police Department, the Collinsville Police Department and one more are each listed by the FBI across several counties including St. Clair County, so their arrests are not broken out for St. Clair County here.
