Phoenix police arrest Ernesto Miranda and extract a written confession during two hours of interrogation without informing him of his right to counsel or his right to remain silent

Phoenix police arrested 23-year-old Ernesto Miranda on March 13, 1963, and took him to an interrogation room where detectives Carroll Cooley and Wilfred Young questioned him for two hours about the rape and kidnapping of an 18-year-old woman. Miranda signed a written confession that included a printed statement claiming it was made voluntarily and with full knowledge of his legal rights — a claim his court-appointed attorney, Alvin Moore, would challenge as meaningless since Miranda had never been told what those rights were. The police acknowledged they had not advised Miranda of his right to remain silent or his right to an attorney.
