If a juror becomes ill or is injured and paramedics or an ambulance are needed, the bailiff shall immediately activate the emergency procedures for a medical emergency. The judge, court clerk and Branch Supervisor shall be informed of the extent of the illness/injury as soon as possible. The jury supervisor shall also be informed. If the juror is to be taken by ambulance to a hospital, the judge may request that a Deputy accompany the juror. If at any time, whether before or after the final submission of the case to the jury, a juror dies or becomes ill, or upon other good cause shown to the court is found to be unable to perform his or her duty, or if a juror requests a discharge and good cause appears therefore, the court may order the juror to be discharged and draw the name of an alternate, who shall then take his or her place in the jury box, and be subject to the same rules and regulations as though he or she has been selected as one of the original jurors.
