The Tenth Circuit affirmed the dismissal of Ryan-Michael Jarvis's civil rights complaint, ruling that law enforcement officers had probable cause to arrest him based on witness reports of threats and aggression at a music festival. The court held that the officers' actions were reasonable under the Fourth Amendment and that the district court correctly applied absolute prosecutorial immunity and qualified immunity to the defendants.

Ryan-Michael Jarvis, a pro se appellant, attended a music festival in Teton County, Wyoming, where he was detained and arrested by Teton County Sheriff's Department officers following reports of a dispute involving a firearm and threats of violence. After being detained overnight and charged with misdemeanors, the state case was eventually dismissed, and Jarvis refunded most of his bail. He then sued the County, the District Attorney, and several officers under 42 U.S.C. § 1983 and other federal statutes, alleging constitutional violations including unlawful seizure, malicious prosecution, and excessive bail. The district court dismissed the complaint under Federal Rule of Civil Procedure 12(b)(6), ruling that the officers had probable cause and that the District Attorney was immune from suit. Jarvis appealed, challenging the dismissal of his claims against both the county and the individual officers.

The Tenth Circuit reviewed the dismissal de novo, accepting all well-pleaded facts as true but rejecting conclusory allegations. Regarding the official capacity claims against the County, the court explained that to survive dismissal, a plaintiff must allege facts showing an official policy, custom, or failure to train that caused the violation. Jarvis failed to identify a specific Teton County policy or widespread practice, rendering his claim fatal. The court also addressed the individual capacity claims. Against District Attorney Hardenbrook, the court affirmed the application of absolute prosecutorial immunity, noting that his actions in initiating and pursuing prosecution are intimately associated with the judicial process. Against the officers, the court found that the district court correctly determined probable cause existed based on witness reports of threats, aggression, and a firearm. The court noted that unsworn witness testimony can support probable cause and rejected Jarvis's reliance on fabricated citations generated by AI tools. Consequently, the officers were entitled to qualified immunity because Jarvis failed to plead facts sufficient to establish a constitutional violation.

The dismissal of Jarvis's civil rights claims stands, leaving the officers and the county without further judicial liability for the arrest and detention. The decision reinforces the high bar for pleading § 1983 official capacity claims against municipalities and confirms that witness reports of threats and aggression can establish probable cause for arrest even in exigent circumstances. The ruling also serves as a warning to pro se litigants regarding the responsibility to verify citations and avoid fabricating legal authority.
