## Facts

- Patrice Seibert’s son died in his sleep; a plan was made to burn the family’s mobile home to conceal the circumstances of the death.
- Donald Rector, a mentally ill 18-year-old living with the family, was left inside the trailer during the fire so it would not appear the deceased son had been left unattended.
- Five days later, Seibert was arrested and taken to a police station for custodial interrogation.
- An officer intentionally withheld Miranda warnings and questioned Seibert for 30–40 minutes, eliciting an admission that the plan contemplated Rector’s death in the fire.
- After a 20-minute pause, the officer administered Miranda warnings, obtained a written waiver, and resumed questioning.
- In the warned phase, the officer referred back to the earlier unwarned admissions and obtained a substantially similar confession.
- The officer testified he was trained to use a “question-first” method: interrogate without warnings, then warn, then repeat questions to obtain the prior answers again.

## Issues

1. Whether a post-Miranda confession is admissible when police deliberately use a two-step “question-first, warn-later” strategy aimed at weakening the effectiveness of Miranda warnings.
2. Whether the rule allowing admission of a later voluntary, warned confession after an earlier unwarned admission applies when the initial failure to warn is an intentional interrogation tactic.

## Decision

- The Supreme Court affirmed the judgment requiring suppression of Seibert’s post-warning confession.
- A plurality concluded that midstream Miranda warnings given after an unwarned custodial confession may be ineffective when the interrogation is effectively continuous and the second round is treated as a continuation of the first.
- Justice Kennedy concurred in the judgment and provided the controlling rule: when police deliberately employ a two-step strategy to circumvent Miranda, post-warning statements must be excluded unless curative measures restore the warnings’ effectiveness.
- Because the interrogation was designed to link the unwarned and warned phases, and no curative measures were used, the post-warning confession was inadmissible.

## Legal Principles

- Miranda warnings must be administered in a manner that reasonably conveys a genuine choice to remain silent or request counsel during custodial interrogation.
- A deliberate two-step interrogation technique—eliciting an unwarned confession, then warning and immediately re-eliciting the same substance—can render the later warnings ineffective and require suppression.
- Under the controlling concurrence, post-warning statements following a deliberate two-step strategy are inadmissible unless curative measures are taken, such as:
  - a substantial break in time and circumstances between the two rounds, or
  - an explicit explanation that the earlier unwarned statement cannot be used as evidence.
- In the absence of deliberateness, the admissibility of a later warned statement generally turns on voluntariness principles governing post-warning confessions after an unwarned statement.

## Conclusion

The Court held that police may not intentionally circumvent Miranda by interrogating first without warnings and then obtaining a repeated confession after warnings; when that tactic is used without effective curative measures, the post-warning confession must be suppressed.
