Whenever a physician, funeral director, or other person has knowledge of a death that may fall under the jurisdiction of the Office of the Chief Medical Examiner in accordance with Health-General Article, §5-308(a), Annotated Code of Maryland, the physician, funeral director, or other person having this knowledge shall report it without delay to the police or sheriff law enforcement agency who has jurisdiction in the city or county where the death occurred. The medical examiner or forensic investigator may, in conjunction with law enforcement or under court authority, investigate any location believed to be associated with the death to gather essential facts to determine cause of death or manner of death. A health care facility may not refuse the medical examiner access to a body which is the subject of a medical examiner investigation at any time.
