The board shall proceed in the selection of jurors in a random manner as ordered by the chief circuit judge as provided in this section. A board member or an employee of the board shall keep a record of the selection process, listing the names of jurors selected. If the name of a person is selected who is not qualified to serve as a juror to the knowledge of any member of the board, an entry of this fact shall be made on the record and that person shall be excused. A record of the selection process shall then be signed by the board member and filed in the office of the board. The signature constitutes a certificate that the record is correct and that all provisions of law have been complied with.
