Section 652.1 — Criminal Code: Trying of issues of indictment by jury

After the charge to the jury, the jury shall retire to try the issues of the indictment. However, if there are more than 12 jurors remaining, the judge shall identify the 12 jurors who are to retire to consider the verdict by having the number of each juror written on a card that is of equal size, by causing the cards to be placed together in a box that is to be thoroughly shaken together and by drawing one card if 13 jurors remain or two cards if 14 jurors remain. The judge shall then discharge any juror whose number is drawn.
