The bill amends Section 150.5 of Title 74 of the Oklahoma Statutes to enhance the procedures for investigations conducted by the Oklahoma State Bureau of Investigation (OSBI). It introduces a new category of individuals authorized to request investigations, specifically designating a "designated person" as an immediate family member of a victim. The bill also updates statutory language, clarifies the criteria for initiating investigations, and establishes a structured process for case file reviews of cold cases. This includes requirements for written requests, confirmation of receipt, and stipulations that only one review can occur at a time for the same victim, with a six-month timeframe for concluding the review.

Additionally, the bill outlines the responsibilities of law enforcement agencies in conducting case file reviews, including the need for coordination among agencies if multiple are involved. It mandates that agencies provide periodic updates to the designated person and prohibits further reviews for the same cold case for five years unless new significant evidence arises. The OSBI is tasked with promulgating rules to implement these provisions, and the act is set to take effect on November 1, 2026.
