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 traumatic brain injury and classified it as a homicide. Approximately 64 hours after Sanders’s arrest—and before any judicial probable-cause determination—he waived his Miranda rights and spoke with a detective. After initially denying responsibility, Sanders offered varying explanations, including that he had shaken the child when she would not stop crying.
A jury convicted Sanders of felony murder and first-degree child abuse, but he later obtained a new trial because his attorney had failed to consult a medical expert about the cause of death. Before the retrial, the trial court ruled that Sanders’s statements were admissible because they were voluntary under People v. Cipriano, despite acknowledging that his detention beyond 48 hours without a probable-cause determination violated the Fourth Amendment under Riverside County v. McLaughlin. 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 unlawfully detained under McLaughlin must be excluded unless the prosecution proves that the statements were sufficiently attenuated from the Fourth Amendment violation. Courts must consider whether Miranda warnings were given, the temporal relationship between the violation and the statements, any intervening circumstances, and the purpose and flagrancy of the police misconduct.
The Court explained that voluntariness is a separate threshold requirement and does not resolve whether a statement resulted from exploitation of an unlawful detention. It overruled People v. Manning to the extent that decision treated Cipriano’s voluntariness analysis as sufficient to protect the distinct Fourth Amendment interests involved. Because the trial court had not conducted the required attenuation analysis, the Supreme Court vacated the order admitting Sanders’s statements and remanded for reconsideration without deciding whether the statements were ultimately admissible.
Key Takeaways
- A confession obtained during an unjustified detention extending more than 48 hours after a warrantless arrest is subject to the Fourth Amendment exclusionary rule.
- Miranda warnings and a finding of voluntariness do not, by themselves, purge the taint of an unlawful detention; the prosecution must separately establish attenuation.
- The Supreme Court did not suppress Sanders’s statements outright. It required the trial court to decide admissibility under the newly announced attenuation standard.
Why It Matters
The decision changes Michigan’s framework for evaluating statements obtained during unconstitutional post-arrest detention. Trial courts may no longer treat the delay in obtaining a probable-cause determination merely as one factor in deciding whether a confession was voluntary.
The ruling also gives law-enforcement agencies a stronger incentive to comply with McLaughlin’s 48-hour rule. Evidence of a recurring departmental practice, prolonged unlawful custody, or purposeful delay may weigh heavily toward suppression, while intervening events that sever the connection between the detention and the statement may support admission.
