No. 25-2129 BRIAN PFALZGRAF, Plaintiff-Appellee,

v.

RUSK COUNTY, WISCONSIN and BEN REISNER, Defendants-Appellants.

Appeal from the United States District Court for the Western District of Wisconsin.

No. 3:23-cv-00877 — James D. Peterson, Chief Judge.

ARGUED FEBRUARY 19, 2026 — DECIDED AUGUST 12, 2026

Before EASTERBROOK, PRYOR, and KOLAR, Circuit Judges. KOLAR, Circuit Judge. A deputy of the Rusk County, Wisconsin Police Department began following Plaintiff Brian Pfalzgraf, supposedly on a hunch. When the deputy saw Pfalzgraf’s license plate covered in snow—a traffic violation —the deputy took the opportunity to pull Pfalzgraf over.

The deputy, Ben Reisner, questioned Pfalzgraf about his travel plans and began to suspect drugs were at play. Deputy 2 No. 25-2129

Reisner claimed to observe Pfalzgraf with dilated pupils and speaking with a “dry mouth.” He also considered Pfalzgraf’s explanations “odd.” Deputy Reisner then called for back-up, frisked Pfalzgraf, searched his car, conducted a dog sniff, and eventually searched Pfalzgraf’s person, revealing a bag of methamphetamine in Pfalzgraf’s pocket.

After Pfalzgraf’s state charges were dismissed, he sued Deputy Reisner and Rusk County, claiming that the traffic stop violated his Fourth Amendment rights. Specifically, he claimed that (1) the initial protective frisk was unlawful, (2) the stop was unlawfully extended, and (3) the search of his person was unsupported by probable cause.

The district court granted partial summary judgment for Pfalzgraf on his frisk and extended-search claims. In its view, no reasonable jury could find either that Deputy Reisner had reasonable suspicion that Pfalzgraf was armed and dangerous , as necessary to justify the frisk, or that he was involved in a distinct drug offense to justify extending the stop. Deputy Reisner now appeals, claiming that genuine disputes of fact precluded summary judgment for Pfalzgraf.

We affirm in part and reverse in part. We agree with the district court that nothing suggested Pfalzgraf was armed or dangerous during the stop. But we find genuine disputes over facts that, if taken in Deputy Reisner’s favor, could support reasonable suspicion of a drug offense that would provide a constitutional justification for extending the stop. Perhaps the district court’s skepticism of the reasons for the extended stop is well-founded, but that is a question for the jury.

I. Background

Deputy Reisner was on patrol in the early hours of the morning when he found himself behind Pfalzgraf’s truck driving south on Highway 27 in Ladysmith, Wisconsin. He saw Pfalzgraf signal to turn into a Kwik Trip gas station, where several police vehicles were parked, before turning the signal off and continuing south. After a short distance, he observed Pfalzgraf exit the highway and start driving the opposite way on a side-street. Finding it “odd” that Pfalzgraf would drive south on the highway only to turn off and head north, Deputy Reisner followed Pfalzgraf. Pfalzgraf then turned back onto the highway and continued heading north. While following Pfalzgraf, Deputy Reisner observed that Pfalzgraf’s license plate was obscured with snow, a traffic violation . See Wis. Stat. § 341.15. As they approached the next intersection, Deputy Reisner flashed his lights and initiated a traffic stop.

The entire interaction between Deputy Reisner and Pfalzgraf was captured on Reisner’s body-worn camera. As Deputy Reisner approached Pfalzgraf’s vehicle, he explained to Pfalzgraf that he had pulled him over because of the obstructed license plate and had observed Pfalzgraf’s change of direction on Highway 27. When asked about his travel plans, Pfalzgraf explained that he had left his house to buy cigarettes . But he changed his mind when he saw the squad cars at the Kwik Trip and “turned around to go back to [his] house.” Remarking that Pfalzgraf’s story “seem[ed] a little odd,” Deputy Reisner took Pfalzgraf’s license and insurance information back to his squad car, scraping the snow from Pfalzgraf’s license plate on the way.

In his police report and deposition, Deputy Reisner explained that he found Pfalzgraf to be “irritable” and “animated ” during this initial interaction, and that Pfalzgraf appeared to have pulled the brim of his hat lower to shield his eyes. Deputy Reisner further claimed that Pfalzgraf’s mouth seemed dry and his pupils dilated, which Reisner considered signs of intoxication given his training and experience. Admitting that he had never interacted with Pfalzgraf before, Deputy Reisner said he had seen Pfalzgraf’s truck parked outside a residence known for drug trafficking on several occasions . The camera footage does not definitively confirm or deny any of these assertions.

Once Pfalzgraf’s license plate was clear of snow, Deputy Reisner radioed dispatch, asking to run Pfalzgraf’s name and license plate in the system. A second officer then arrived, and Reisner told her that he suspected Pfalzgraf of a drug crime, stating “961, something going on here”—a reference to Wisconsin ’s statutory chapter on drug offenses. Returning to Pfalzgraf’s vehicle, Deputy Reisner asked Pfalzgraf to step out of his truck and asked if he had any weapons on his person (to which Pfalzgraf replied “no”). Deputy Reisner frisked the outside of Pfalzgraf’s clothing despite Pfalzgraf’s protests that he “didn’t do nothing.” He then continued to question Pfalzgraf for several minutes about his “agitated” demeanor, avoiding the gas station, and whether Pfalzgraf had taken any controlled substances. Pfalzgraf denied taking drugs, and when further probed by Reisner, declared that he could pass a field sobriety test and a blood test.

Unconvinced, Deputy Reisner obtained Pfalzgraf’s verbal consent to conduct a K-9 sniff of his vehicle. Deputy Reisner walked his K-9, Boone, around the exterior of the vehicle, and

according to Reisner (but disputed by Pfalzgraf), Boone changed his behavior consistent with the presence of controlled substances. Now about fifteen minutes into the stop, Deputy Reisner told Pfalzgraf that Boone had detected drugs and received his permission to manually search the truck. Deputy Reisner searched the truck’s cab, engine bay, and undercarriage , but found no contraband or drug paraphernalia.

Finally, almost thirty minutes into the stop, Deputy Reisner asked Pfalzgraf whether he had anything in his pockets, which Pfalzgraf denied. Deputy Reisner then stated his intention to search Pfalzgraf, and instructed Pfalzgraf to remove his hands from his pockets. Seeing Pfalzgraf gripping something , he told Pfalzgraf to open his fist, revealing a bag that Deputy Reisner identified as, and was later confirmed to be, methamphetamine. Pfalzgraf admitted to using methamphetamine earlier in the day and acknowledged that his blood was likely to test positive for that substance. Deputy Reisner placed Pfalzgraf under arrest for possession of methamphetamine and operating a vehicle while under the influence of a controlled substance.

Pfalzgraf was later charged in state court, but all charges were dismissed after the State agreed with Pfalzgraf that the traffic stop had been unlawfully extended and that any evidence obtained from it should be suppressed. Pfalzgraf then sued Deputy Reisner and his employer, Rusk County, in federal court under Title 42 U.S.C. § 1983, alleging three Fourth Amendment violations. Count I alleged that Deputy Reisner patted him down early in the traffic stop without reasonable suspicion that Pfalzgraf was armed or dangerous. Count II asserted that Deputy Reisner deviated from the initial mission of the stop—the obstructed license plate—and extended the 6 No. 25-2129
