An order may issue only on an affidavit or affidavits sworn to before the judge and establishing the following grounds for the order:
(1) That there is probable cause to believe that a felony offense, or a Class A1 or Class 1 misdemeanor offense has been committed;
(2) That there are reasonable grounds to suspect that the person named or described in the affidavit committed the offense; and
(3) That the results of specific nontestimonial identification procedures will be of material aid in determining whether the person named in the affidavit committed the offense. (1973, c. 1286, s. 1; 1997-80, s. 14.)
