Background

Pennsylvania State Police intercepted a suspicious UPS package containing six pounds of methamphetamine. Trooper Cody Montz obtained an order authorizing officers to place and monitor a GPS tracker in the package, along with a warrant to search Apartment 2 at the delivery address. Montz’s supporting affidavit also requested permission to enter and secure any secondary location to which the package was taken while officers sought another warrant—a procedure known as a “hit-and-hold”—but neither judicial order expressly granted that authority.

After an undercover officer delivered the package, Davone Walker carried it into Apartment 1. Montz directed officers to enter that apartment and secure the scene, believing the tracker order incorporated the affidavit and authorized the hit-and-hold. Officers then obtained a separate warrant for Apartment 1 and found methamphetamine, fentanyl pills, cocaine, and drug paraphernalia. The District Court found Montz’s belief unreasonable but denied suppression because his error amounted, at most, to isolated negligence. Walker entered a conditional guilty plea and appealed.

The Court’s Holding

The Third Circuit affirmed the denial of Walker’s suppression motions and his conviction. Because the government conceded that the initial entry into Apartment 1 was not authorized by the warrant or tracker order, the court assumed that the hit-and-hold violated the Fourth Amendment. But it held that an unlawful search does not automatically require exclusion of the resulting evidence.

The court concluded that Montz’s conduct was not deliberate, reckless, grossly negligent, or part of recurring or systemic negligence. The tracker order stated that it incorporated the warrant application “for all purposes,” and the incorporated affidavit expressly requested permission to enter a secondary location and secure the package. Although Montz mistakenly believed that language authorized entry into Apartment 1, the court characterized his interpretation as an understandable, isolated error that would not be meaningfully deterred by suppression.

Key Takeaways

  • A Fourth Amendment violation does not by itself require suppression; the exclusionary rule generally targets deliberate, reckless, grossly negligent, or systemic police misconduct.
  • An officer’s mistaken reliance on language incorporating a warrant application may constitute only isolated negligence, even when the judicial order does not expressly authorize the action taken.
  • Because Montz sought judicial authorization, knew the package was inside Apartment 1, secured the scene, and obtained a second warrant before conducting the evidentiary search, suppression was unwarranted.

Why It Matters

The decision reinforces the Third Circuit’s distinction between finding a Fourth Amendment violation and applying the exclusionary rule. Evidence may remain admissible when an officer acts on an understandable but incorrect reading of judicial authorization, so long as the mistake does not rise to gross negligence or more culpable misconduct.

Judge Mascott joined the opinion as an application of governing Supreme Court precedent but separately noted that the officer’s conduct may not have been mistaken at all and, in her view, fell outside the exclusionary-rule doctrine because it was undertaken in good faith.
