The National Case Closed Project: Supporting Evidence-Based Practices for Violent Crime Investigations

The National Case Closed Project Logo


Funded by the U.S. Department of Justice’s Bureau of Justice Assistance, the National Case Closed Project is a new nationwide program designed to support law enforcement agencies in improving their violent crime clearance rates, with an emphasis on fatal and nonfatal shooting cases. The project team will partner with local law enforcement agencies to identify effective and sustainable practices related to agency operations, agency resources, investigator capabilities, and community relations. Technical assistance will be provided to partner agencies, and educational materials will be developed that law enforcement agencies across the nation can use to improve their violent crime clearance rates.

Violent Crime Clearance Rates

The U.S. Department of Justice’s Bureau of Justice Assistance and RTI International invite law enforcement agencies to apply to join BJA’s National Case Closed Program. This new nationwide effort will support law enforcement agencies in improving their violent crime clearance rates, especially in shooting cases.

The project will partner with selected law enforcement agencies to increase clearance rates by identifying and implementing effective and sustainable practices related to agency operations, agency resources, investigator capabilities, and community relations. This free (federally funded) assistance will be provided by practitioners and researchers who are national leaders in criminal investigation, evidence collection and crime scene processing, prosecution, victim advocacy, and forensic science.

Agencies selected to participate will receive:

  • An in-depth assessment to help improve fatal and nonfatal shooting clearance rates
    • Site visits
    • Personnel interviews
    • Analysis of policies and training materials
    • In-depth review of investigative case files
    • Examination of other agency data
  • Recommendations to address identified gaps
  • Ongoing technical assistance in implementing recommendations and tracking results
  • Input in a national program to help develop evidence-based standards and recommendations on the investigation and clearance of shooting cases

The first round of applications for participation in the National Case Closed Project is now closed. Agencies interested in future participation are encouraged to apply during the next round of applications in spring 2023 and to subscribe to receive updates and resources from the National Case Closed Project below.
