Misleading the Suspect
From that partial plate, the investigators discovered that Ernesto Miranda was their top suspect. Mr. Miranda was arrested on March 13, 1963, and taken into the police station. He was placed in a lineup to be identified. Unfortunately, the victim wasn’t able to positively recognize him as her attacker, but Miranda was led to believe otherwise. He asked the police how he did afterward, and Captain Carroll Cooley responded, saying: “Not too good, Ernie.”

It’s important to note that Miranda only had a 9th-grade education. He didn’t even know the constitution, let alone understand the law. Because of this, he was an easy suspect for detectives to work with.
