(b) If the death of a police officer is caused by a cardiac event, stroke or pulmonary embolism that occurred not later than twenty-four hours after such officer concluded a shift or training, the police chief of such officer's law enforcement unit shall have the authority to determine whether such officer died in the line of duty, unless a local charter or ordinance in effect on October 1, 2024, provides the authority to a different individual or entity to make such determination. Such declaration by a police chief shall not be used as evidence for a workers' compensation claim under chapter 568.
