(1) That the juror is not a citizen, resident in the county;

(2) That the juror is under 18 years of age;

(3) That the juror is incompetent to serve because of mental illness or mental retardation, or that the juror is intoxicated;

(4) That the juror is so near of kin to the prosecutor, the accused, or the victim as to disqualify the juror by law from serving on the jury;

(6) That the juror is unable to communicate in the English language.
