United States v. Tracy Jones, 70 F.4th 1109

Tracy Jones arrested on November 17, 2020 on a federal indictment for conspiracy to distribute 500+ grams of methamphetamine.
She waived Miranda and confessed during a ~44-minute post-arrest interview within two hours of arrest.
Law enforcement transported her to county jail the next day but failed to notify the magistrate; she was not presented to a magistrate judge until 37 days later (December 23, 2020).
Jones moved to dismiss the indictment (arguing Rule 5 and substantive due process violations) and to suppress her post-arrest statements (arguing an unlawful two-step interrogation and involuntariness).
The district court denied both motions; Jones pled guilty and was sentenced to 120 months. She appealed the denials.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the 37-day delay in initial presentment violated substantive due process and warrants dismissal	Jones: prolonged, unexplained delay and alleged pattern/deliberate indifference violated Due Process and shocks the conscience	Government: delay resulted from nonfeasance/administrative error, not deliberate or outrageous conduct; dismissal not appropriate remedy for Rule 5 violation	Court: Rule 5(a) was violated but conduct did not "shock the conscience"; no substantive due process violation and dismissal improper
Whether statements from the post-arrest interview must be suppressed (Seibert two-step / involuntary waiver)	Jones: agent’s pre-warning statements and interrogation tactic created a two-step Seibert violation and rendered the Miranda waiver involuntary	Government: pre-warning remarks were brief and narrow (about charges/mandatory minimum), not a prolonged two-step interrogation; waiver was knowing and voluntary	Court: pre-warning exchange was brief/narrow, not Seibert-style; waiver and confession were voluntary; suppression denied
