Ohio Revised Code Title XXIX. Crimes Procedure § 2923.03

(A) No person, acting with the kind of culpability required for the commission of an offense, shall do any of the following:

(B) It is no defense to a charge under this section that no person with whom the accused was in complicity has been convicted as a principal offender.

(C) No person shall be convicted of complicity under this section unless an offense is actually committed, but a person may be convicted of complicity in an attempt to commit an offense in violation of section 2923.02 of the Revised Code.

(D) If an alleged accomplice of the defendant testifies against the defendant in a case in which the defendant is charged with complicity in the commission of or an attempt to commit an offense, an attempt to commit an offense, or an offense, the court, when it charges the jury, shall state substantially the following:

“The testimony of an accomplice does not become inadmissible because of his complicity, moral turpitude, or self-interest, but the admitted or claimed complicity of a witness may affect his credibility and make his testimony subject to grave suspicion, and require that it be weighed with great caution.

It is for you, as jurors, in the light of all the facts presented to you from the witness stand, to evaluate such testimony and to determine its quality and worth or its lack of quality and worth.”

(E) It is an affirmative defense to a charge under this section that, prior to the commission of or attempt to commit the offense, the actor terminated his complicity, under circumstances manifesting a complete and voluntary renunciation of his criminal purpose.

(F) Whoever violates this section is guilty of complicity in the commission of an offense, and shall be prosecuted and punished as if he were a principal offender. A charge of complicity may be stated in terms of this section, or in terms of the principal offense.
