2921.22 Failure to report a crime or knowledge of a death or burn injury.
(A)
(1) Except as provided in division (A)(2) of this section, no person, knowing that a felony has been or is being committed, shall knowingly fail to report such information to law enforcement authorities.
(2) No person, knowing that a violation of division (B) of section
2913.04 of the Revised Code has been, or is being committed or that the person has received information derived from such a violation, shall knowingly fail to report the violation to law enforcement authorities.
(B) Except for conditions that are within the scope of division (E) of this section, no person giving aid to a sick or injured person shall negligently fail to report to law enforcement authorities any gunshot or stab wound treated or observed by the person, or any serious physical harm to persons that the person knows or has reasonable cause to believe resulted from an offense of violence.
(C) No person who discovers the body or acquires the first knowledge of the death of a person shall fail to report the death immediately to a physician or advanced practice registered nurse whom the person knows to be treating the deceased for a condition from which death at such time would not be unexpected, or to a law enforcement officer, an ambulance service, an emergency squad, or the coroner in a political subdivision in which the body is discovered, the death is believed to have occurred, or knowledge concerning the death is obtained. For purposes of this division, "advanced practice registered nurse" does not include a certified registered nurse anesthetist.
(D) No person shall fail to provide upon request of the person to whom a report required by division (C) of this section was made, or to any law enforcement officer who has reasonable cause to assert the authority to investigate the circumstances surrounding the death, any facts within the person's knowledge that may have a bearing on the investigation of the death.
