Modifies provisions relating to medical providers' participation in criminal investigations

HB 646 requires medical providers treating patients with gunshot wounds or stabbing wounds at least one inch deep to immediately report specific details (like the patient's name/address or description, wound nature, and treatment circumstances) to law enforcement. It provides legal immunity to licensed medical professionals who make such reports in good faith, protecting them from civil liability. The bill also mandates emergency rooms to store forensic evidence securely and provides for state-developed evidence collection kits for these cases, distributed by health and public safety departments. These provisions directly affect hospitals, emergency medical staff, and law enforcement handling violent injury cases.
