Facts

Respondent was arrested for violating a restraining order while officers were also investigating information that he, a convicted felon, possessed a Glock pistol. Detective Benner began to give Miranda warnings but stopped after respondent interrupted and said he knew his rights, and the officers did not complete the warnings. Benner then asked about the Glock, respondent said it was in his bedroom, and he gave permission to retrieve it. Benner found and seized the pistol, which the Government sought to use in a felon-in-possession prosecution.

Issue

Does a failure to give full Miranda warnings require suppression of physical evidence discovered as a result of a suspect's unwarned but voluntary statements? More specifically, does the fruit of the poisonous tree doctrine apply to nontestimonial physical fruits of such statements?

Rule

The failure to give Miranda warnings does not require suppression of the physical fruits of a suspect's unwarned but voluntary statements. Miranda is a prophylactic rule protecting the Self-Incrimination Clause, and that Clause is implicated by compelled testimonial evidence, not by the admission of nontestimonial physical evidence derived from voluntary statements. A mere failure to warn does not itself violate the Constitution or Miranda, so Wong Sun's fruit-of-the-poisonous-tree doctrine does not apply on that basis.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

In Phoenix, police arrested Daniel Ruiz on an outstanding warrant and questioned him in custody without first giving Miranda warnings. When an officer asked where the stolen laptop was, Daniel calmly said it was in a storage locker he rented, and officers then recovered the laptop from that locker.

If Daniel moves to suppress the laptop solely because it was found through an unwarned custodial statement, how should the court rule?

Explanation. The majority rule is that the failure to give Miranda warnings does not require suppression of nontestimonial physical evidence derived from a suspect's unwarned but voluntary statement. The Self-Incrimination Clause protects against compelled testimonial evidence, and the admission of physical evidence like a laptop does not itself implicate that clause. Because a mere failure to warn is not itself a constitutional violation, Wong Sun derivative-fruit suppression does not apply on that basis.
