4th Cir.

UNITED STATES OF AMERICA v. NATHANIEL MARTIN

April 17, 2026 ·25-4233 ·2-1 ·Judge DeAndrea Gist Benjamin · By James Taylor

The Fourth Circuit reversed a district court's denial of a motion to suppress, holding that a Forest Service officer unreasonably extended a traffic stop to investigate unrelated criminal activity. The court found the officer abandoned the stop's original mission immediately, violating the Fourth Amendment under the standard set in Rodriguez v. United States.

Nathaniel Martin was a passenger in a vehicle driven by Melisa Jarvis in the Monongahela National Forest. A United States Forest Service officer, Joshua Radford, stopped the vehicle because it was illegally parked on a single-lane bridge. During the stop, Radford immediately asked the occupants if there were any firearms in the vehicle, leading to the discovery of two guns. Approximately twelve and a half minutes into the encounter, after running license checks, Radford arrested Martin, who had prior felony convictions, and secured the second firearm. Two and a half years later, Martin was charged with being a felon in possession of a firearm. He moved to suppress the evidence, arguing the stop was unlawfully extended to investigate crimes unrelated to the traffic violation. The district court denied the motion, finding the questioning was permissible, but Martin appealed.

The Fourth Circuit applied the two-step inquiry from Terry v. Ohio, focusing on whether the officer's actions were reasonably related in scope to the initial purpose of the stop. The court emphasized that a traffic stop must last no longer than necessary to effectuate its mission, which is to address the traffic violation and attend to related safety concerns. The court found that Officer Radford exceeded the scope of the seizure by immediately engaging in a criminal investigation unrelated to the traffic violation. Unlike the officer in United States v. Buzzard, who asked safety-related questions mid-stop after encountering erratic behavior, Radford led the stop with questions about firearms. The court noted that Radford did not feel he was in danger, did not secure the occupants, and allowed the driver to reach into the vehicle while a firearm was known to be present. The court rejected the argument that the remote location alone justified the immediate deviation from the stop's mission, stating that officer safety interests must stem from the mission of the stop itself. The court concluded that Radford abandoned the stop from its inception and did not diligently pursue the purpose of the stop.

The district court's judgment is vacated, and the case is remanded for further proceedings consistent with excluding the unlawfully seized evidence. This means the defendant's guilty plea is vacated, and the government must either retry the case without the suppressed evidence or dismiss the charges. The decision clarifies that officers cannot immediately abandon a traffic stop's mission to investigate unrelated crimes, even in remote areas, unless specific safety concerns justify the deviation.
