Medicolegal investigations; broadening certain investigative requirements; requiring certain notice to parent or legal guardian. Effective date.
SB 1484 requires Oklahoma medical examiners to conduct standardized investigations for sudden infant or young deaths (including SIDS, SUID, SDY, and SADS), mandating autopsies when needed, review of medical records, and documentation of recent immunizations. It requires medical examiners to notify parents or legal guardians before investigations begin and grants them the right to refuse parts of the process unless a crime is suspected. The bill expands mandatory investigations to cover all sudden unexplained deaths in children under 20, requiring reporting to a national CDC/NIH registry and sharing findings with the State Department of Health. This directly affects medical examiners, parents/guardians of deceased children, and state health authorities through new procedural requirements.

MINOR
The bill was amended to transition from a House version to a Senate version, which added a new sponsor (Representative Roe) and reorganized the text formatting. The substantive policy content regarding medicolegal investigations, definitions of sudden death, and reporting requirements remains consistent between the two versions.
Scope change
The scope of the bill itself (investigations into sudden infant and young adult deaths) has not changed; only the legislative metadata and text formatting were updated.
TECHNICAL
Added Representative Roe as a co-sponsor to the bill.
Updated the header to reflect the Senate Floor Version and adjusted page numbering and formatting.
Reorganized the text layout and line breaks to match Senate floor standards while preserving the original legislative language.
