United States v. James Bumphus, 227 A.3d 559

Police stopped James Bumphus’s Lincoln Aviator Friday night on a tip from a confidential informant that the vehicle contained a handgun; officers had probable cause to seize the car.
After Bumphus exited the vehicle he tossed his keys to another person; officers handcuffed him and held him for ~2.5 hours until a tow truck arrived; the locked car was towed to MPD storage.
MPD retained the car at its storage facility for four days (Friday night–Tuesday); Sergeant Bagshaw testified he delayed seeking a warrant because he thought weekends were for emergencies and the car was secure.
On Tuesday Bagshaw obtained a warrant, opened the car with a Slim Jim and found a handgun and ammunition.
The Superior Court found (1) the initial seizure was supported by probable cause, but (2) the four‑day retention and delayed search—without any legitimate explanation or diligence—violated the Fourth Amendment, and (3) the gun and ammo were suppressed as fruits of the unreasonable seizure.
The D.C. Court of Appeals affirmed: it applied a Place/Johns balancing of government justification versus possessory interests, found the delay unreasonable and police conduct not in good faith, and upheld suppression.

Issue	Bumphus’s Argument	Government’s Argument	Held
Whether a 4‑day seizure with delayed search was reasonable under the Fourth Amendment	The four‑day retention absent any legitimate need or diligence violated the Fourth Amendment; suppression required	Probable cause to seize the vehicle made any short delay immaterial; Johns allows delay and the automobile exception should control	Affirmed for Bumphus. Court applied Place/Johns balancing, found no legitimate justification or diligence for the delay, and held the extended seizure unreasonable
Whether the gun/ammunition must be excluded as fruit of the unlawful seizure	Evidence is fruit of the unreasonable seizure and must be suppressed to deter violations	Sergeant acted in good faith; later warrant and Hudson causation reasoning mean exclusion is unwarranted	Affirmed suppression. Good‑faith exception inapplicable; later warrant did not purge the taint and deterrence supports exclusion
Whether officers could/should have searched without a warrant at the scene and whether officer’s legal understanding mattered	Officer misunderstood law; Ross permits warrantless vehicle searches on probable cause, so waiting showed lack of diligence	Officer sought a warrant because no consent; weekend procedures and workload justified delay	Court found officer’s testimony legally incorrect and his inaction unexplained; this supported the conclusion of lack of diligence and unreasonableness
