Mercer County Arrest Records
The Mercer County Sheriff's Office in Princeton handles all law enforcement for the county. Mercer County is very small and rural, sitting in north-central Missouri near the Iowa border. The jail has 12 beds when it is in use, but the facility is not always operational. When the jail is closed or full, inmates arrested in Mercer County are held at neighboring county facilities.
The sheriff's office adopted the Kologik CAD/RMS/JMS system in 2021. This is a computer-aided dispatch and records management system that tracks arrests, calls for service, and jail records.

Mercer County Records System
In 2021, Mercer County adopted the Kologik CAD/RMS/JMS system. This is a computer-aided dispatch, records management, and jail management platform that tracks all arrests, calls for service, and inmate records in one place. Before Kologik, the county relied on a more manual system for its records. The new platform improved how arrest data is stored, searched, and shared with other agencies.
The Kologik system helps even when the jail is not in use. Arrest records still go through the system and are maintained by the sheriff's office. If someone is arrested in Mercer County and held at another jail, the booking data stays in the Mercer County system. This means the sheriff's office can pull up records quickly when you make a request, even if the inmate was moved to a different facility right after booking.
