The following procedure shall govern jury trials which include any felony charges:
(1) The jury shall first hear all evidence relevant to every charge on which a defendant is being tried and shall retire to reach a verdict on each charge;
(2) If the defendant is found guilty of one (1) or more charges, the jury shall then hear additional evidence relevant to sentencing on those charges. Evidence introduced in the guilt phase may be considered, but need not be reintroduced at the sentencing phase;
(3) Following the introduction of additional evidence relevant to sentencing, if any, instruction on the law, and argument, the jury shall again retire and determine a sentence within the statutory range;
(4) The court, in its discretion, may also instruct the jury that counsel may argue as to alternative sentences for which the defendant may qualify. The jury, in its discretion, may make a recommendation as to an alternative sentence. However, this recommendation shall not be binding on the court;
(5) After a jury finds guilt, the defendant, with the agreement of the prosecution and the consent of the court, may waive jury sentencing, in which case the court shall impose sentence; and
(6) After a plea of guilty, the defendant, with the agreement of the prosecution and the consent of the court, may be sentenced by a jury impaneled for purposes of sentencing only.
