United States v. Walker, 4:20-cr-00222

Background

On April 30, 2020 HPD Officers Foster and Polk observed Jesse Walker driving rapidly out of a nightclub parking lot in a known high‑crime area, then make an erratic left/U‑turn; officers followed and initiated a traffic stop.
Squad‑car computer returned that Walker matched the name on outstanding traffic warrants and had prior felony conviction and gang affiliation; officers asked for ID and observed furtive reaching toward the center console.
Officers ordered Walker out, handcuffed him for officer safety, and during brief questioning Walker admitted there was a pistol in the center console; officers recovered the pistol.
HSI Agent Kayade Ereme later Mirandized Walker and obtained post‑Miranda statements; officers also seized a cell phone and later obtained and executed a search warrant for its contents.
Walker moved to suppress (pre‑ and post‑Miranda) statements, the pistol, and the phone contents; the district court denied the motions in a March 12, 2021 memorandum opinion.

Issues

Issue	Walker's Argument	Government's Argument	Held
Legality of initial traffic stop	Stop unlawful; video does not show traffic violations	Officers observed speeding and illegal U‑turn; computer showed outstanding warrants	Stop justified: officers credibly observed speeding and an illegal U‑turn; squad‑car warrant info also supported stop
Validity/use of municipal complaints / outstanding warrants	Complaints underlying warrants are conclusory and insufficient; warrants must be produced	Computer record of outstanding warrants provided officers probable cause; officers did not rely on deficient complaints	Officers reasonably relied on computer record; exclusionary rule inapplicable under good‑faith/Leon/Herring principles
Pre‑Miranda statements (admission of pistol) / custody question	Statements made after being told of warrants and while handcuffed were custodial and required Miranda	Stop remained an investigative Terry detention; handcuffing was a safety measure; public‑safety exception applies if custodial	Not custodial for Miranda (brief, public, noncoercive Terry detention); alternatively admissible under public‑safety exception
Search/seizure of pistol and phone	Firearm and phone are fruits of unlawful arrest/search and must be suppressed	Walker admitted pistol’s presence (probable cause); vehicle would have been towed and inventoried; phone later searched under warrant	Officers had probable cause to search (felon in possession); evidence also admissible under inevitable discovery/inventory doctrine; phone searched pursuant to valid warrant
Post‑Miranda statements and alleged two‑step Seibert tactic	Post‑Miranda statements tainted by pre‑Miranda questioning; two‑step deliberate tactic barred under Seibert	No deliberate two‑step strategy; different agency performed Miranda warnings; Elstad governs voluntary pre‑warning statements	No evidence of deliberate two‑step tactic; Elstad applies; post‑Miranda statements admissible (pre‑warning statements were voluntary)
