United States v. Bradley, 370 F. Supp. 3d 458

At ~1:43 a.m. Trooper Johnson stopped Gary Bradley for speeding and weaving; Bradley provided ID and a rental agreement and was asked to sit in the trooper's patrol car.
Bradley exhibited nervousness (tremor, labored breathing); Trooper Johnson conducted a frisk and ran computer checks, then engaged in extended questioning about travel, family, and criminal history.
Corporal Hoye arrived and stood at the passenger door; Johnson then asked pointed questions about drugs and other contraband, after which Bradley admitted there was cocaine in the car (pre‑Miranda).
Trooper Johnson then read Miranda warnings, obtained further admissions about quantity and location (post‑Miranda), cuffed Bradley, and found a vacuum‑sealed kilogram of cocaine in the trunk.
Bradley moved to suppress admissions and the cocaine, arguing custodial interrogation without Miranda, coercion, and unlawful prolongation of the traffic stop; government defended noncustodial stop, voluntariness, and inevitable discovery.
The district court granted the suppression motion: it found Bradley was in custody from Corporal Hoye’s arrival, that questioning constituted interrogation, that the officer’s failure to Miranda was deliberate (Seibert), curative measures were not given, and the post‑Miranda statements and physical evidence were suppressed; inevitable discovery was rejected.

Issue	Bradley's Argument	Government's Argument	Held
Was Bradley "in custody" (Miranda) when he made statements?	Confined to trooper's car, flanked by armed troopers, night, could not leave; therefore custody.	Routine traffic stop; short, public, noncoercive; Berkemer controls.	In custody from arrival of backup; reasonable person would not feel free to leave.
Did police conduct "interrogation" under Miranda?	Extended, repeated, substance‑focused questioning exceeded routine traffic inquiries.	Questions were standard/clarifying and not coercive.	Yes: questions were reasonably likely to elicit incriminating responses.
Were post‑Miranda statements admissible given prior unwarned statements? (Elstad/Seibert)	Pre‑warning admission tainted later statements; warnings did not cure because police used a two‑step, deliberate strategy.	Any failure to warn was inadvertent; proper Miranda thereafter cures under Elstad.	Officer's failure was deliberate and warnings were ineffective; post‑Miranda admissions suppressed under Seibert/Kennedy rule.
Is the cocaine admissible under inevitable discovery or as independently obtained?	Suppression required because admissions were fruit of unwarned, coercive interrogation.	Even if statements inadmissible, K‑9 or impound/inventory would have inevitably uncovered the cocaine.	Government failed its burden to prove inevitable discovery; physical evidence suppressed.
