Which Agency Holds a Report from Marysville
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 Marysville that is the agency that reports to the FBI for the city (filed by the FBI as Marysville Police Department); outside it, the St. Clair County Sheriff's Office.
The FBI's list also places the St. Clair County State Police in St. Clair County; a report taken on a state highway by it comes from that agency's own records office.
The Memphis Police Department and the Richmond Police Department 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.
