The Supreme Court overturned the Court of Appeals' decision and restored Alvarado's conviction. The Court said that being "in custody" was a matter of law, not of whether Alvarado believed he was in custody. Even though Alvarado was a minor, he was not in custody by law, so he did not have to be reminded of his Miranda rights.

The confession can be used, because Alvarado was not in custody.
The confession can be used, because Alvarado thought that he could leave.
