384 U.S. 436, 86 S. Ct. 1602, 16 L.Ed.2d 694 (1966)
Ernesto Miranda was arrested for kidnapping and rape. The victim identified Miranda in a police lineup. After two hours of interrogation room, the police come forward with a signed confession from Miranda. He was convicted and sentenced to 20-30 years. Police did not inform Miranda of 5th amendment right against self-incrimination and of his 6th amendment right to attorney. Miranda confessed in writing to the crimes
The officers admitted at trial that Miranda was not advised that he had a right to have an attorney present. At his trial before a jury, the written confession was admitted into evidence over the objection of defense counsel, and the officers testified to the prior oral confession made by Miranda during the interrogation. Miranda was found guilty of kidnapping and rape. He was sentenced to 20 to 30 years' imprisonment on each count, the sentences to run concurrently.
Miranda appealed case to Arizona Supreme Court, arguing that his confession should be excluded because he had not been informed of his rights. Arizona Supreme Court denied his appeal and upheld his conviction
