The Case Closure and Witness Support Amendment Act of 2025 aims to enhance the support and protection of witnesses in homicide cases within the District of Columbia. The bill introduces a minimum payment of $50,000 for individuals who provide information leading to the adjudication or conviction of homicide offenders. Additionally, it mandates the Mayor to promote available witness assistance resources and establishes a Witness Protection and Assistance Program to ensure the safety and wellbeing of those who cooperate with law enforcement during investigations and legal proceedings.

Furthermore, the bill requires the Comprehensive Homicide Elimination Strategy Task Force to submit a report by December 1, 2025, detailing the District's witness protection programs, including recommendations for improvement. The report will cover various aspects such as current procedures, safety measures, available support services, and an assessment of the fiscal impact of witness assistance. The legislation also outlines specific protections and assistance that may be provided to witnesses and their families, including relocation, housing expenses, and mental health support, thereby aiming to create a more robust framework for witness protection in the District.
