Project Overview

The St. Louis Metropolitan Police Department (SLMPD) proposes to proactively address violent crime by improving the quality of evidence recovered and data generated and improving information sharing efforts among local criminal justice agencies. Hot spots policing, proven as an effective evidenced-based practice, will be at the core of the approach. SLMPD will integrate their gunshot detection system with existing SLMPD technologies such as Geographic Information System (GIS) Mapping and Computer Aided Dispatch (CAD). SLMPD will also pilot a Mobile Surveillance Unit (MSU), a unique self-contained mobile trailer surveillance system specifically designed for remote monitoring. SLMPD will monitor incoming data through their Real Time Crime Center (RTCC) to proactively respond to reports of crime and improve investigative methods. The project will also complement a BJA-awarded grant for the Police Prosecutor Partnership Initiative, which provides funding to support the recovery of bullet casings for entry into the NIBIN and for the assignment of a dedicated prosecutor to the GCIC.
