OPINION
Thе appellant juvenile was found delinquent after confessing to his junior high school principal that he had set a fire in a student locker. We hold that appellant’s statements were voluntary, that the juvenile court correctly found them admissible into evidence, and that the principal was neither obliged to give Miranda 1 warnings to the juvenile nor to give him the warnings required of peace officers and court officers pursuant to Rule 7(a), Arizona Rules of Procedure for the Juvenile Court, 17B Ariz.Rev. StatAnn. (“A.R.S.”).
Background
Appellant started a fire in a locker at Show Low Junior High School, which burnеd out before doing much harm. Dr. Norman Ehmke, the principal, investigated, intending to report his findings to the police. Reports from students and faculty led Dr. Ehmke to appellant, who initially denied involvement. Appellant was asked to remain in the vicinity of the principal’s office, and did so. After questioning other students, Dr. Ehmke questioned appellant again.
Appellant was neither restrained nor threatened. Dr. Ehmke testified that appellant “may have been told that if there was a violation of the law police would be involved.” But Dr. Ehmke did not tell appellant of his rights pursuant to Rule 7(a) or Miranda.
In their second interview, appellant admitted that he had started the locker fire. Dr. Ehmke called the police and, whеn an officer arrived, had appellant repeat his admission.
In delinquency proceedings in the juvenile court, appellant sought and received a voluntariness hearing concerning his confession to Dr. Ehmke. 2 After the juvenile court found appellant’s statements admissible, appellant entered a plea agreement and was ordered to serve 40 days in juvenile detention, followed by one year on рrobation.
Custodial Interrogation
Rule 7(a), Arizona Rules of Juvenile Procedure, provides in part:
No extra-judicial statement to a peace officer or court officer by the child shall be admitted into evidence in juvenile court over objection unless the person offering the statemеnt demonstrates to the satisfaction of the court that: the statement was voluntary and before making the statement the child was informed and intеlligently comprehended that the child need not make a statement, that any statement made might be used in a court proceeding, and that the child had a right to consult with counsel prior to making a statement and during the taking of the statement, and that, if the child or the child’s parents, guardiаn or custodian could not afford an attorney, the court would appoint one for the child prior to any questioning.
This warning, known as “the juvenile
Miranda
warning,” need only be given to a juvenile suspect under circumstances in which
Miranda
warnings would be required.
In re Maricopa County Juvenile Action No. JV-501010,
Miranda
warnings are a prophylactic measure, required at the outset of custodial interrogation, to prevent the state from extracting involuntary confessions from a criminal suspect.
Miranda,
Law enforcement agents include government employees “whose primary mission is to enforce the law.”
In re Victor F.,
We conclude that Dr. Ehmke did not act as an instrument or agent оf the police. As a principal responsible for safety, administration, and discipline in his school, Dr. Ehmke had the independent responsibility to investigate a student infraction committed on school grounds during school hours. He did not act at the behest or direction of the policе; he initiated and conducted the investigation on his own. That Dr. Ehmke intended to report the results of his investigation to the police did not alone make him an agent or instrumentality of the police or oblige him to give “juvenile
Miranda
” warnings to his suspect.
See Snyder,
In short, Dr. Ehmke was not an agent or instrumentality of the police, nor did he engage in custodial interrogation; and the absence of juvenile Miranda warnings did not render appellant’s confession to Dr. Ehmke inadmissible.
Voluntariness
Appellant also asserts that his confession should have been suppressed because the State failed to rebut the presumption thаt it was involuntary and coerced. Confessions are presumed to be involuntary. To establish their admissibility, the State must prove the contrary by a рreponderance of the evidence.
Maricopa County Juvenile Action No. JV-501010,
We find that the State met its burden of proof, presenting substantial evidence that appellant’s statements were voluntary, not coerced. Dr. Ehmke testified without contradiction that he made no threats or promises; he used no physical force, and questioning took place in a familiar setting. Appеllant introduced no evidence of coercion, nor did he claim that his. ability to reason was impaired; his only objection was lack of Mi *207 randa warnings, and we have explained above that such warnings were not required,
Conclusion
Because appellant’s confession to Dr. Ehmke was neithеr involuntary nor acquired in violation of Miranda or Rule 7(a), we find no error on appeal. The judgment of the trial court is affirmed.
Notes
.
Miranda
v.
Arizona,
. The record does not indicate whether Miranda warnings or Rule 7(а) warnings were given before appellant repeated his confession to the police. Our record on appeal cоncerns only the voluntariness of appellant’s statements to Dr. Ehmke. As appellant entered a plea agreement after the court accepted the voluntariness of the statements to Dr. Ehmke, the question of admissibility of the statements to the police did not arise.
