How was Ernesto Miranda convicted again after the Supreme Court ruling?

The Supreme Court’s 1966 ruling in Miranda v. Arizona reversed Ernesto Miranda’s initial conviction because his confession was obtained without the required procedural safeguards, specifically the Miranda warnings regarding his right to remain silent and his right to an attorney.12

Following the Supreme Court's decision, Miranda was retried by the state of Arizona. Although his original confession was excluded from the second trial, the prosecution was able to secure a conviction by presenting other evidence, including testimony from his common-law wife regarding his confession to her. He was subsequently convicted of kidnapping and rape and sentenced to prison.
