A. If an offender is indicted on or after August 1, 2017, for the crime of first degree murder (La. Rev. Stat. 14:30) where the offender was under the age of eighteen years at the time of the commission of the offense, the district attorney may file a notice of intent to seek a sentence of life imprisonment without possibility of parole within one hundred eighty days after the indictment. If the district attorney timely files the notice of intent, a hearing shall be conducted after conviction and prior to sentencing to determine whether the sentence shall be imposed with or without parole eligibility. If the court determines that the sentence shall be imposed with parole eligibility, the offender shall be eligible for parole pursuant to the provisions of La. Rev. Stat. 15:574.4(E). If the district attorney fails to timely file the notice of intent, the sentence shall be imposed with parole eligibility and the offender shall be eligible for parole pursuant to the provisions of La. Rev. Stat. 15:574.4(E) without the need of a judicial determination pursuant to the provisions of this Article. If the court determines that the sentence shall be imposed without parole eligibility, the offender shall not be eligible for parole.

            B.(1) If an offender was indicted prior to August 1, 2017, for the crime of first degree murder (La. Rev. Stat. 14:30) or second degree murder (La. Rev. Stat. 14:30.1) where the offender was under the age of eighteen years at the time of the commission of the offense and a hearing was not held pursuant to this Article prior to August 1, 2017, to determine whether the offender’s sentence should be imposed with or without parole eligibility, the district attorney may file a notice of intent to seek a sentence of life imprisonment without the possibility of parole within ninety days of August 1, 2017. If the district attorney timely files the notice of intent, a hearing shall be conducted to determine whether the sentence shall be imposed with or without parole eligibility. If the court determines that the sentence shall be imposed with parole eligibility, the offender shall be eligible for parole pursuant to La. Rev. Stat. 15:574.4(G). If the district attorney fails to timely file the notice of intent, the offender shall be eligible for parole pursuant to La. Rev. Stat. 15:574.4(E) without the need of a judicial determination pursuant to the provisions of this Article. If the court determines that the sentence shall be imposed without parole eligibility, the offender shall not be eligible for parole.

            (2) If an offender was indicted prior to August 1, 2017, for the crime of first degree murder (La. Rev. Stat. 14:30) or second degree murder (La. Rev. Stat. 14:30.1) where the offender was under the age of eighteen years at the time of the commission of the offense and a hearing was held pursuant to this Article prior to August 1, 2017, the following shall apply:

            (a) If the court determined at the hearing that was held prior to August 1, 2017, that the offender’s sentence shall be imposed with parole eligibility, the offender shall be eligible for parole pursuant to La. Rev. Stat. 15:574.4(G).

            (b) If the court determined at the hearing that was held prior to August 1, 2017, that the offender’s sentence shall be imposed without parole eligibility, the offender shall not be eligible for parole.

            C. At the hearing, the prosecution and defense shall be allowed to introduce any aggravating and mitigating evidence that is relevant to the charged offense or the character of the offender, including but not limited to the facts and circumstances of the crime, the criminal history of the offender, the offender’s level of family support, social history, and such other factors as the court may deem relevant. The admissibility of expert witness testimony in these matters shall be governed by Chapter 7 of the Code of Evidence.

            D. The sole purpose of the hearing is to determine whether the sentence shall be imposed with or without parole eligibility. The court shall state for the record the considerations taken into account and the factual basis for its determination. Sentences imposed without parole eligibility and determinations that an offender is not entitled to parole eligibility should normally be reserved for the worst offenders and the worst cases.
