The Homicide Victim’s Families Rights Act of 2021 is a proposed bill that, if passed, aims to grant relatives of homicide victims the right, under federal law, to request a review of their loved one’s case once it has become cold for a period of three years. If the federal investigator determines that this review could yield valuable leads, a comprehensive reinvestigation would then be initiated. Additionally, the bill mandates that the federal government inform family members of their rights and provide regular updates regarding ongoing cold case reviews. Furthermore, the bill seeks to collect data on the challenges associated with cold cases. The underlying rationale behind this legislation is that a fresh perspective can unveil overlooked facts or new evidence, and leveraging advanced techniques and tests that were previously unavailable during the initial investigation may potentially uncover new information.
