Background
John Harold Sanders was arrested without a warrant in January 2013 after bringing his three-month-old daughter to a hospital with severe injuries. The child died that evening, and an autopsy attributed her death to a traumatic brain injury and classified it as a homicide. About 64 hours after Sanders’s arrest, before any judicial probable-cause determination, he waived his Miranda rights and gave police varying accounts of the injuries, including that he shook the child when she would not stop crying. A magistrate found probable cause later that day.
A jury convicted Sanders of felony murder and first-degree child abuse, but he later obtained a new trial based on ineffective assistance of counsel arising from his attorney’s failure to consult a medical expert. Before the retrial, the trial court found that the delay in obtaining a probable-cause determination violated the Fourth Amendment under Riverside County v. McLaughlin, but admitted Sanders’s statements as voluntary under People v. Cipriano. The Court of Appeals denied interlocutory review, and the Michigan Supreme Court heard argument on Sanders’s application for leave to appeal.
The Court’s Holding
In lieu of granting leave to appeal, the Michigan Supreme Court held that statements made while an arrestee is detained in violation of the Fourth Amendment’s prompt-probable-cause requirement must be suppressed unless the prosecution proves that the statements were sufficiently attenuated from the unlawful detention. Courts must consider the Miranda warnings, the temporal relationship between the violation and the statements, intervening circumstances, and the purpose and flagrancy of the police misconduct. Because a McLaughlin violation continues until a judicial probable-cause determination occurs, a longer unlawful detention generally weighs against attenuation.
The Court explained that voluntariness under Cipriano and People v. Stewart remains a separate threshold requirement but does not resolve whether a statement resulted from exploitation of a Fourth Amendment violation. It overruled People v. Manning to the extent Manning treated Cipriano’s voluntariness inquiry as sufficient to protect the distinct Fourth Amendment interests involved. The Court did not decide whether Sanders’s statements were admissible or whether the trial court clearly erred in finding them voluntary; it vacated the admission order and remanded for an attenuation analysis.
Justice Brian K. Zahra dissented. He would have affirmed the order admitting Sanders’s statements, retained Manning, and held that Cipriano’s totality-of-the-circumstances voluntariness review adequately addressed statements obtained during a McLaughlin violation without a separate Fourth Amendment attenuation analysis. In his view, suppression’s costs outweighed its deterrent benefits, particularly given alternative remedies such as civil liability and exclusion of involuntary statements.
Key Takeaways
- A voluntary statement made during an unlawful post-arrest detention is not automatically admissible; the prosecution must also establish attenuation from the Fourth Amendment violation.
- Miranda warnings favor attenuation but do not alone purge the taint, and an increasingly prolonged McLaughlin violation generally weighs against admissibility.
- The Court vacated and remanded without deciding whether Sanders’s challenged statements ultimately must be suppressed.
Why It Matters
The decision changes Michigan’s framework for statements obtained after a warrantless arrestee has been held more than 48 hours without a judicial probable-cause determination. Trial courts must now conduct both a voluntariness inquiry and, when a McLaughlin violation occurred, a distinct Fourth Amendment attenuation analysis.
The ruling also places the burden on prosecutors to show attenuation and makes evidence of recurring or systemic delay practices especially relevant to whether suppression is warranted. Justice Zahra’s dissent highlights the competing view that voluntariness review and civil remedies provide adequate deterrence without excluding probative statements.
