Ohio Revised Code Title XXIX. Crimes Procedure § 2945.12

A person indicted for a misdemeanor, upon request in writing subscribed by him and entered in the journal, may be tried in his absence by a jury or by the court. No other person shall be tried unless personally present, but if a person indicted escapes or forfeits his recognizance after the jury is sworn, the trial shall proceed and the verdict be received and recorded. If the offense charged is a misdemeanor, judgment and sentence shall be pronounced as if he were personally present. If the offense charged is a felony, the case shall be continued until the accused appears in court, or is retaken.
