The proposed bill, titled "The Decker Act," establishes a framework for reviewing and reinvestigating cold case murders in Florida. It creates a new section, 782.41, in the Florida Statutes, which defines key terms such as "cold case," "designated person," and "law enforcement agency." The bill mandates that heads of law enforcement agencies or their designees must review cold cases upon receiving a written application from a designated person, typically an immediate family member of the victim. The review process includes assessing investigative procedures, interviewing witnesses, and examining physical evidence. If the review indicates that a full reinvestigation may yield new leads or identify a perpetrator, the agency is required to conduct a comprehensive reinvestigation.

Additionally, the bill outlines specific requirements for law enforcement agencies, including the development of written applications for cold case reviews, training for personnel, and reporting data to the Global Forensic and Justice Center at Florida International University. The center is tasked with maintaining a case tracking system and a public website that provides information on cold case investigations. The law enforcement agencies must also provide written confirmation of application receipt and can deny applications that do not meet established criteria, along with providing a written explanation for any denials. The act is set to take effect on July 1, 2026, and applies to cold cases from January 1, 1970, onward.
