United States v. Walker, 49 F.4th 903

Background

On April 30, 2020, HPD Officers Polk and Foster observed a Nissan Altima driving erratically and leaving a high-crime parking lot; a plate check returned municipal traffic warrants listing Jesse Walker and identified him as a felon and gang member.
Officers stopped the vehicle for traffic violations; Foster asked Walker for his license, had safety concerns when he could not see Walker’s hands, asked him to exit, and then handcuffed him.
Polk asked Walker if there was anything in the car; Walker said there was “something you might take me to jail for” and disclosed a pistol in the console; Polk recovered the firearm and a cell phone.
Homeland Security Agent Ereme later read Walker his Miranda rights and interviewed him; the car was offered to Walker’s girlfriend but ultimately was hooked to a tow truck and subjected to an HPD inventory.
Walker was indicted under 18 U.S.C. § 922(g)(1) for being a felon in possession of a firearm; he moved to suppress the firearm, cell phone (and subsequent phone-search evidence), and his statements; the district court denied suppression and Walker pled guilty reserving appellate review of suppression denial.
The Fifth Circuit affirmed, rejecting challenges to the stop/arrest, the application of the good‑faith exception to municipal warrants, the Miranda argument, and holding the firearm and phone would have been inevitably discovered via a valid inventory search.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Legality of traffic stop/arrest	Officers had reasonable suspicion/probable cause (erratic driving/turn) to stop; warrants justified arrest	Stop/arrest unjustified; officers mischaracterized the turn and lacked valid basis	Stop justified; district court’s credibility findings not clearly erroneous; traffic violations observed supported stop
Reliance on municipal warrants / good‑faith exception	Officers reasonably relied on computer warrants; good‑faith exception applies even if warrants later invalid	City’s warrant practice systemically produces defective warrants, making officer reliance reckless	Good‑faith exception applies; no record evidence of systemic or reckless municipal error; reliance objectively reasonable
Admission of pre‑Miranda statements	Statements not prejudicial because firearm would have been inevitably discovered	Statements elicited during custodial interrogation before Miranda and should be suppressed	Even assuming custodial questioning, statement about the gun was not independently significant because firearm inevitable via inventory search; no suppression required
Seizure of firearm and cell phone / inventory search	HPD General Order 600‑10 authorizes nonconsent tow and standardized inventory; car was subject to tow and inventory so items would be lawfully discovered	Inventory could have been improper/evidentiary; car could/should have been released to girlfriend instead of towed	HPD policy constitutional and was properly applied; vehicle subject to nonconsent tow and inventory so discovery of gun and phone was inevitable
