Ohio Rev. Code Ann. § 2152.13
(A) A juvenile court shall impose a serious youthful dispositional sentence on a child when required under division (B)(3) of section 2152.121 of the Revised Code. In such a case, the remaining provisions of this division and divisions (B) and (C) do not apply to the child, and the court shall impose the mandatory serious youthful dispositional sentence under division (D)(1) of this section. In all other cases, a juvenile court may impose a serious youthful offender dispositional sentence on a child only if the prosecuting attorney of the county in which the delinquent act allegedly occurred initiates the process against the child in accordance with this division, and the child is an alleged delinquent child who is eligible for the dispositional sentence. The prosecuting attorney may initiate the process in any of the following ways:
(4) Until an indictment or information is obtained, if the original complaint does not request a serious youthful offender dispositional sentence, filing with the juvenile court a written notice of intent to seek a serious youthful offender dispositional sentence within twenty days after the later of the following, unless the time is extended by the juvenile court for good cause shown:
(C)
(1) A child for whom a serious youthful offender dispositional sentence is sought by a prosecuting attorney has the right to a grand jury determination of probable cause that the child committed the act charged and that the child is eligible by age for a serious youthful offender dispositional sentence. The grand jury may be impaneled by the court of common pleas or the juvenile court. Once a child is indicted, or charged by information or the juvenile court determines that the child is eligible for a serious youthful offender dispositional sentence, the child is entitled to an open and speedy trial by jury in juvenile court and to be provided with a transcript of the proceedings. The time within which the trial is to be held under Title XXIX of the Revised Code commences on whichever of the following dates is applicable:
