Background
John Harold Sanders was arrested without a warrant in January 2013 after bringing his three-month-old daughter to a hospital with injuries that a physician suspected resulted from abuse. The child later died, and an autopsy classified her death as a homicide caused by traumatic brain injury. After Sanders had been detained for at least 64 hours without a judicial probable-cause determination, he waived his Miranda rights and gave police varying accounts of the child’s injuries, including that he shook her when she would not stop crying.
A jury convicted Sanders of felony murder and first-degree child abuse, but the trial court later granted him a new trial because his attorney had not obtained medical-expert assistance concerning the cause of death. Before retrial, the court ruled that Sanders’s statements were admissible because they were voluntary under Michigan’s totality-of-the-circumstances test. Although the court recognized that the detention violated the Fourth Amendment rule requiring a prompt probable-cause determination after a warrantless arrest, it treated the delay as only one factor bearing on voluntariness. The Court of Appeals denied interlocutory review.
The Court’s Holding
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 excluded unless the prosecution proves that the statements were sufficiently attenuated from the unconstitutional detention. Courts must consider the giving of Miranda warnings, temporal proximity, intervening circumstances, and the purpose and flagrancy of the police misconduct. Because the violation continues until a probable-cause determination occurs, a longer unlawful detention generally weighs against attenuation.
The Court distinguished attenuation from voluntariness. Voluntariness remains a threshold requirement and an independently sufficient ground for suppression, but it does not determine whether a statement resulted from exploitation of a Fourth Amendment violation. The Court therefore overruled People v Manning to the extent it treated the voluntariness inquiry as sufficient to protect the Fourth Amendment interests involved.
The Court did not decide whether Sanders’s statements were admissible. It vacated the trial court’s order admitting them and remanded for the trial court to conduct the required attenuation analysis. The Court also expressed no opinion on whether the trial court clearly erred in finding the statements voluntary.
Key Takeaways
- A voluntary statement obtained during detention that violates the 48-hour probable-cause rule may still require suppression under the Fourth Amendment.
- The prosecution bears the burden of showing that the statement was sufficiently attenuated from the unlawful detention.
- Miranda warnings favor attenuation but do not, by themselves, purge the taint of an unconstitutional seizure.
- The Supreme Court vacated the admission order without deciding the ultimate admissibility of Sanders’s statements.
Why It Matters
The decision establishes a distinct Fourth Amendment remedy for statements obtained during prolonged warrantless detention in Michigan. Trial courts may no longer resolve admissibility solely by finding a confession voluntary; they must separately examine whether the unlawful detention caused or was exploited to obtain the statement.
The ruling also gives law-enforcement agencies a direct evidentiary incentive to obtain timely judicial probable-cause determinations. Evidence of a recurring departmental practice that disregards the constitutional deadline may weigh strongly toward suppression.
