When from challenge or from any other cause there is not a sufficient number of persons in attendance to complete a panel of trial jurors, the judge shall draw tales jurors from the jury box of the county and shall order the sheriff to summon the jurors so drawn. When the sheriff or his deputy is disqualified to summon tales jurors, they may be summoned by the coroner or such other person as the judge may appoint after their names have first been drawn from the jury box by the judge as above provided.
