Flight-Discarded Contraband Is Abandoned (and Public Surveillance Footage Is Independently Sourced) Even If the Later Detention Is Unlawful

Introduction

In United States v. Kendre Cain (3d Cir. June 22, 2026) (nonprecedential), the Third Circuit affirmed the denial of a motion to suppress (1) a firearm recovered near the defendant after a foot chase and (2) apartment-building surveillance video showing the defendant tossing the gun during flight. Two Pittsburgh detectives, initially looking to execute an arrest warrant for someone else, mistakenly followed Cain, recognized him, called out his name, and Cain immediately ran. During pursuit, Cain discarded a small black object later recovered as a firearm. Cain was later detained at taser-point, patted down, and questioned. He argued that the detention was unconstitutional and sought suppression of both the firearm and the video.

The key issues on appeal were whether Cain retained a Fourth Amendment privacy interest in the firearm he discarded while fleeing and whether the surveillance footage was suppressible as fruit of an allegedly unlawful detention.

Summary of the Opinion

The Third Circuit held that suppression was properly denied regardless of whether Cain’s eventual detention was constitutional. The court reasoned:

  • The firearm was not suppressible because Cain abandoned it when he tossed it into a public alleyway during flight—before any seizure of his person—terminating any Fourth Amendment privacy interest.
  • The surveillance video was not suppressible because Cain had no reasonable expectation of privacy in security footage of a public space, and in any event the gun’s lawful recovery provided an independent source basis to seek the video.

Standards of Review

The court framed its review using United States v. Mendoza (quoting United States v.  Dyer): factual findings are reviewed for clear error, legal conclusions plenarily, and the record is viewed in the light most favorable to the Government when suppression is denied. This framing matters because the outcome turned on the timing and location of Cain’s discard (during flight, into a public alley) and on established Fourth Amendment doctrines (abandonment; independent source).

Fourth Amendment Standing / Privacy Interest

Citing Rawlings v.  Kentucky, the panel emphasized that ownership alone does not carry a suppression remedy; the defendant must show a privacy interest in the item at the time of seizure. This “privacy interest” requirement sets the stage for abandonment doctrine: once privacy is relinquished, Fourth Amendment protection typically ends.

Abandonment Doctrine in the Third Circuit

The court relied on United States v. Fulani for the proposition that abandonment terminates Fourth Amendment privacy interests, and on United States v. Harrison for the governing test: under the totality of the circumstances, there must be “clear and unequivocal evidence” of intent to abandon, assessed objectively (not by subjective intent). United States v. Harrison also cited United States v. Liu for the practical point that physically relinquishing property often suffices to establish abandonment.

The panel analogized Cain’s conduct to two concrete abandonment examples:

  • United States v. Fulani: a passenger disclaimed baggage in the overhead rack—treated as abandonment notwithstanding a bag bearing his name.
  • United States v. Martin: a suspect discarded packets during a brief flight from police—treated as abandonment.

Timing of “Seizure” and the Non–Fruit-of-the-Poisonous-Tree Principle

The court’s central authority was California v. Hodari D., which held that an arrest/seizure requires either physical force or, absent that, submission to a show of authority. Critically, California v. Hodari D. concluded that objects discarded during flight—before submission—are treated as abandoned and are not fruit of an unlawful seizure because the discard precedes the seizure.

In a detailed footnote, the panel rejected Cain’s attempt to narrow California v. Hodari D. by arguing it did not “squarely” decide abandonment. The Third Circuit read California v. Hodari D. as treating abandonment of pre-seizure discarded contraband as uncontroversial, and noted the Supreme Court’s reliance on Hester v. United States (containers dropped by fleeing moonshiners deemed abandoned).

Attempted Contrary Authority

Cain relied on United States v. Ramirez (5th Cir. unpublished), which distinguished concealment from abandonment when a suspect throws an item onto private, fenced family property where he retains a reasonable expectation of privacy. The Third Circuit found United States v. Ramirez nonbinding and, more importantly, distinguishable: Cain discarded the firearm into a public alleyway, not into a private enclave where he could claim ongoing privacy.

Surveillance Footage and Independent Source

For the video, the court invoked Katz v.  United States: what a person knowingly exposes to the public is not protected by the Fourth Amendment. Separately, it applied the independent-source doctrine from Murray v. United States, reasoning that lawful recovery of the gun supplied an independent basis to seek nearby footage even if Cain had escaped and no detention occurred.

Legal Reasoning

  1. The firearm: abandonment defeats suppression.

    The panel did not need to resolve the constitutionality of Cain’s eventual detention because the dispositive event occurred earlier: Cain tossed the gun while running. Under United States v. Fulani and United States v. Harrison, the objective act of physically discarding the gun into a public alley constitutes “clear and unequivocal” evidence of abandonment in Fourth Amendment terms. Under Rawlings v.  Kentucky, once abandonment ends Cain’s privacy interest, he lacks the necessary Fourth Amendment interest to suppress the gun.

    California v. Hodari D. supplies the timing rule: because Cain discarded the gun before he submitted to the officer’s show of authority, the discard occurred before any seizure. Thus, even if the later detention were unlawful, the gun is not fruit of the poisonous tree because the causal chain is broken by the pre-seizure abandonment.

  2. The video: no privacy interest, and also independently sourced.

    The panel offered two independent grounds:

    • Under Katz v.  United States, Cain cannot claim Fourth Amendment protection in a recording of what he exposed to public view (running through publicly visible areas and discarding an object into a public alley).
    • Under Murray v. United States, even assuming a constitutional defect in the detention, the video was obtainable via an independent source—namely, the lawfully recovered gun providing an investigative basis to canvass for nearby cameras.

Impact

Although labeled “NONPRECEDENTIAL” and “not binding precedent” under Third Circuit I.O.P. 5.7, the decision is a clear application—and practical reaffirmation—of two durable Fourth Amendment principles in chase-and-discard cases:

  • Chase-and-discard strategy is unlikely to yield suppression where contraband is tossed into a public area before the suspect is seized, given the combined force of abandonment doctrine (United States v. Fulani, United States v. Harrison) and the seizure-timing rule (California v. Hodari D.).
  • Public-facing surveillance video is difficult to suppress when it captures events in spaces lacking a reasonable expectation of privacy and when police can show an independent investigative pathway (Katz v.  United States; Murray v. United States).

Practically, the opinion signals that litigating the legality of the eventual stop may be insufficient if the key evidence was discarded pre-seizure in a public place. Defendants may instead focus future suppression efforts on contesting (where plausible) whether the discard truly occurred pre-seizure, whether the location was genuinely public (as contrasted with the private-property setting discussed in United States v. Ramirez), or whether police obtained video through means that were not actually independent.

Complex Concepts Simplified

“Abandonment” (Fourth Amendment)
Not the same as giving up ownership under property law. For Fourth Amendment purposes, abandonment asks whether a person’s conduct objectively shows they gave up a reasonable expectation of privacy in the item. If so, police recovery generally does not implicate the Fourth Amendment.
“Seizure” of a person
Under California v. Hodari D., a person is seized when police apply physical force or when the person submits to a show of authority. Running away is not submission; discarding contraband while fleeing typically occurs before a seizure.
“Fruit of the poisonous tree”
Evidence can be suppressed if it is derived from unconstitutional police conduct. But if the evidence was abandoned before any unconstitutional act (or before any seizure), it is not “fruit” of that conduct.
“Independent source” doctrine
Even if some police conduct was unlawful, evidence is not suppressed if police also obtained it (or would have obtained it) from a separate, lawful basis independent of the illegality, as discussed in Murray v. United States.
Reasonable expectation of privacy
Under Katz v.  United States, the Fourth Amendment generally does not protect what is knowingly exposed to the public. A person’s ability to claim privacy often turns on location (public alleyway versus private, fenced property).

Conclusion

The Third Circuit affirmed denial of suppression because Cain discarded the firearm during flight into a public alleyway—objectively abandoning it before any seizure—and because the surveillance footage captured public exposure and was also supported by an independent-source rationale. Even as a nonprecedential decision, United States v. Kendre Cain consolidates a familiar but decisive practical rule for suppression litigation: where contraband is discarded pre-seizure in a public place, disputes about the later detention often do not affect admissibility of the discarded evidence or closely connected public-area video obtained independently.
