Fla. Stat. § 406.145
When an unidentified body is transported to a district medical examiner pursuant to this chapter, the medical examiner shall immediately report receipt of such body to the appropriate law enforcement agency, provided such law enforcement agency was not responsible for transportation of the body to the medical examiner. If the medical examiner cannot determine the law enforcement agency having jurisdiction, he or she shall notify the sheriff of the county in which the medical examiner is located, who shall determine the law enforcement agency responsible for the identification. It is the duty of the law enforcement officer assigned to and investigating the death to immediately establish the identity of the body. If the body is not immediately identified, the law enforcement agency responsible for investigating the death shall enter data concerning the body, through the Florida Crime Information Center, into the Unidentified Person File of the National Crime Information Center.
