St. Mary Parish, Louisiana, has about 47,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from St. Mary Parish depends on where the incident happened: the St. Mary Parish Sheriff's Office for the unincorporated parish, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Louisiana Public Records Law requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from St. Mary Parish
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.
In St. Mary Parish that is the St. Mary Parish Sheriff's Office for the unincorporated parish and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
