D.P. MARSHALL, JR., District Judge.
First, the length of the stop was reasonable. United States v. Anguiano, 795 F.3d 873, 876-77 (8th Cir. 2015). Trooper Hill obtained information about Cheryl and Daniel. Then he arrested Cheryl. Daniel seemed anxious to the Trooper. Reasonably suspecting some criminal activity, the Trooper waited about fifteen minutes on the other officers to bring Dux. The officers were diligent; the stop's length didn't violate the Constitution. United States v. Bloomfield, 40 F.3d 910, 916-17 (8th Cir. 1994) (en banc).
Second, Trooper Hill had at least arguable probable cause to search Daniel. After Dux alerted on Daniel's jeep, Officers Boling and Gamber didn't find anything. Daniel was the jeep's last occupant. It was therefore reasonable to conclude that he might possess the contraband. United States v. Chartier, 772 F.3d 539, 545-46 (8th Cir. 2014).
Last, Trooper Hill had a reason to arrest Daniel. The Trooper believed Daniel illegally possessed potpourri. ARK. CODE ANN. § 5-64-419; Brodnicki v. City of Omaha, 75 F.3d 1261, 1264-65 (8th Cir. 1996). Daniel had admitted his possession during the search. No 40 at 17-18.
The Court, though, cannot conclude as a matter of law that Officer Boling had arguable probable cause to search Daniel's jeep. Dux is a reliable police dog. No 36-6; Florida v. Harris, 568 U.S. 237, 243-47 (2013). But Daniel says that Officer Boling created the probable cause by telling Dux to sit and alert. No 36-3 at 5, 7. Officer Boling denies this. He says he can't make Dux alert. No 36-4 at 7. All this testimony creates a genuine dispute of material fact. Because Dux's alert is critically important in the probable cause analysis, a forced alert would undermine the basis for searching this Jeep. See United States v. Donnelly, 475 F.3d 946, 955 (8th Cir. 2007).
This factual dispute, however, doesn't affect the legal analysis about Officer Gamber or Trooper Hill. Daniel hasn't offered any evidence that they were aware of or involved in the allegedly false alert. Parrish v. Ball, 594 F.3d 993, 1001 (8th Cir. 2010). Officer Gamber therefore had arguable probable cause for searching the jeep based on Dux's alert; and Trooper Hill likewise had arguable probable cause for searching Daniel.
Trooper Hill didn't violate Daniel's First Amendment rights in retaliation for his words at the scene. A retaliatory-arrest claim requires that the arrest lack probable cause. Nieves v. Bartlett, 139 S.Ct. 1715, 1725-26 (2019); Waters v. Madson, 921 F.3d 725, 741 (8th Cir. 2019). And a retaliatory-detention claim requires that the detention lack reasonable suspicion. Waters, 921 F.3d at 736-38, 741-42. Trooper Hill had probable cause to arrest Daniel for admittedly having potpourri. Similarly, Trooper Hill had a reasonable suspicion to search Daniel's jeep, even though it would require some delay. The initial stop for no headlights, Cheryl's warrant, and Daniel's nervous behavior created a reason to detain the couple briefly to get a K9 search done. United States v. Foley, 206 F.3d 802, 806 (8th Cir. 2000).
Officers Boling and Gamber's motion for summary judgment, No 35, is mostly granted and partly denied. Trooper Hill's motion, No 37, is granted. For every federal claim that is dismissed, the parallel claims under the Arkansas Constitution are also dismissed: they turn on the same facts; and the state law isn't different from federal law. All Cheryl's claims are dismissed with prejudice. We'll have a trial on Daniel's remaining search claims (federal and state) against Officer Boling. First, did he prompt Dux's alert by telling the dog to sit? If not, Officer Boling had arguable probable cause to search. Second, if Officer Boling told Dux to sit, then he lacked arguable probable cause. And the only remaining question will be Daniel's damages flowing from the search. An Amended Final Scheduling Order will issue.
So Ordered.
