What happened during Ernesto Miranda's police interrogation?

During his interrogation, Ernesto Miranda was identified in a police lineup and subsequently questioned by authorities regarding charges of kidnapping and rape. Over the course of a two-hour interrogation, Miranda provided a confession and signed a written statement.12

Crucially, police failed to inform Miranda of his right to remain silent or his right to have an attorney present to advise him during the questioning. Because these procedural safeguards were absent, the U.S. Supreme Court later ruled in Miranda v. Arizona that his confession was inadmissible as evidence at his trial. This landmark decision established that prosecutors cannot use statements obtained during custodial interrogation unless suspects are first advised of their constitutional rights, now commonly known as Miranda warnings.12
