United States v. Sanders, 796 F.3d 1241

Background

Aurora police found Beverly Sanders’ car legally parked in a private Goodwill lot; Sanders was arrested on an outstanding warrant as she exited the store.
Sanders said a third party could pick up the car; officers did not ask who could retrieve it, and did not offer authorized municipal alternatives (liability release or private tow).
Officers decided to impound the car citing a fear of theft/vandalism in a high-crime area; Aurora’s municipal code did not list private-lot impoundment for that reason.
Police conducted an inventory search after impoundment and discovered suspected controlled substances; Sanders was indicted and moved to suppress the evidence.
The district court granted suppression because the impoundment was not authorized by Aurora policy; the government appealed under 18 U.S.C. § 3731.

Issues

Issue	Plaintiff's Argument (Sanders)	Defendant's Argument (Government)	Held
Whether impoundment of a vehicle on private property without standardized criteria violates the Fourth Amendment	Impoundment was unlawful because vehicle was legally parked on private property and officers failed to follow or offer municipal alternatives	Impoundment justified by community-caretaking exception (prevent theft/vandalism)	Court: Unconstitutional — impoundments from private property require both standardized criteria and a legitimate community-caretaking rationale
Whether a community-caretaking rationale alone can validate impoundment absent standardized policy	Officers’ stated theft risk was pretextual and insufficient; they made no meaningful effort to arrange alternatives	Community-caretaking (risk of break-in in high-crime area) suffices to protect vehicle and public safety	Court: Even if safety concern exists, where not impeding traffic or an immediate hazard, standardized policy plus non-pretextual rationale are required; here both prongs fail
Whether evidence from inventory search is admissible after unlawful impoundment	Evidence should be suppressed as fruits of unconstitutional seizure	Evidence admissible because search was routine inventory following arrest/impoundment	Court: Suppress — inventory search invalid because impoundment unlawful
