Jury commissioners shall cause cards to be prepared such that the name of each person on the jury list shall appear on one card. Such cards shall be of uniform kind and size. Such cards shall be placed in a wheel designated by the commissioner, and while in the wheel shall be thoroughly mixed. After such cards are thoroughly mixed in the wheel, cards may be drawn therefrom as provided in this act for selection of members of jury panels. There shall be one and only one wheel for each county, and the commissioner shall assure that it is kept securely locked and it shall be maintained under the control of the commissioner. In the event that a county has appropriate base information programmed as a part of its computer operations so that it might comply with the spirit of the jury selection laws of Kansas the jury commissioners may by local rule provide alternate methods for securing jury panels directly from the computer without the necessity of drawing names or cards from a wheel manually.
