The actions of the police amounted to the functional equivalent of interrogation. As a result, A.A. should have been advised of his Miranda rights in the presence of his mother. To hold otherwise would turn Presha and the safeguards it envisioned on their head. To address the special concerns presented when a juvenile is brought into custody, police officers should advise juveniles of their Miranda rights in the presence of a parent or guardian before the police question, or a parent speaks with, the juvenile. Officers should then let the parent and child consult in private. That approach would afford parents a meaningful opportunity to help juveniles understand their rights and decide whether to waive them. Because A.A.’s inadmissible statements comprised a substantial part of the proofs against him, a new hearing is necessary.
