The proposed bill, titled "The Decker Act," establishes a framework for reviewing and reinvestigating cold case murders in Florida. It creates a new section in the Florida Statutes, specifically section 782.41, 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 must assess whether a full reinvestigation could yield new probative leads or identify a likely perpetrator. If warranted, a full reinvestigation must be conducted, adhering to specific requirements outlined in the bill.

Additionally, the bill requires law enforcement agencies to develop written applications for cold case reviews, provide training to relevant personnel, and issue written confirmations of application receipt. It also stipulates that agencies must report data related to cold case reviews to the Global Forensic and Justice Center at Florida International University, which will maintain a case tracking system and a public website with relevant information. The act is subject to appropriations and applies to cold cases from January 1, 1970, onward, with an effective date of July 1, 2026.
