Before McHUGH, EID, and ROSSMAN, Circuit Judges. _________________________________

In 2019, a group of law enforcement officers and prosecutors in Teton County,

Wyoming investigated and prosecuted Robert Charles Rosen and William Michael

Crothers based on allegations of sexual assault against them. Both men ultimately

prevailed against the accusations: the prosecutors dropped the charges against Rosen

before trial, and Crothers was acquitted of his sexual assault charge after trial.

Feeling that they had been unfairly targeted, Rosen and Crothers subsequently sued

several law enforcement officers in the Teton County Sheriff’s Office (the “TCSO

defendants,” collectively)1 and several prosecutors in the Teton County Prosecutor’s

Office (the “TCPO defendants,” collectively).2

Rosen and Crothers brought several claims (together and separately) under 42

U.S.C. § 1983, alleging, inter alia, violations of the Fourth and Fourteenth

Amendments, municipal liability under Monell v. Department of Social Services, 436

U.S. 658 (1978), and violations of state law.3 The TCSO and TCPO defendants

1 The TCSO defendants consist of Teton County Sheriff Matt Carr (sued in both his official and individual capacities) and Deputies Breton Bommer, David Hodges, Clayton Platt, and Andrew Roundy (sued in their individual capacities). 2 The TCPO defendants consist of the Teton County Prosecutor’s Office, Prosecuting Attorney Erin Weisman (sued in both her official and individual capacities), and Chief Deputy Prosecutor Clark Allan (sued in his individual capacity). 3 The lawsuit also involved a third plaintiff, Peter Muldoon, who was the mayor of Jackson Hole, Wyoming from 2016 until 2020. Muldoon initially filed a notice of appeal on a single First Amendment retaliation claim under § 1983, but thereafter voluntarily moved to dismiss his appeal. This Court granted his motion. See Crothers, et al. v. Carr, et al., No. 23-8014, slip op. at 2 (10th Cir. June 30, 2 Appellate Case: 23-8014 Document: 136-1 Date Filed: 04/16/2025 Page: 3

moved for summary judgment, which the district court granted as to all sixteen

claims. Rosen and Crothers appealed. Reviewing the issues de novo, we affirm.

I.

Robert Charles Rosen and William Michael Crothers are two strangers who found

themselves in similar predicaments. Both men were accused of sexual assault—

wrongfully, they allege. Eventually, both prevailed against the accusations. But during

each of their prosecutions, both men experienced what they contend was unlawful

conduct by law enforcement officers and prosecutors in Teton County, Wyoming.

A.

The allegations against Rosen were brought in September 2019, when Rosen was

seventeen years old. Another minor, I.U., alleged that Rosen sexually assaulted her while

they were at Rosen’s house after hanging out at a music festival and at a country club.

Deputy Breton Bommer, an investigator with the Teton County Sheriff’s Office

(“TCSO”), interviewed I.U. shortly after she made her allegations. During the interview,

I.U. provided details of the assault; she also told Deputy Bommer that while she was with

Rosen, she texted her friends, pleading for them to pick her up so that she could get away

(although she did not provide screenshots of those text messages until months later).

After the interview, Deputy Bommer believed he had probable cause to arrest Rosen, but

he delayed doing so.

2023) (order). Because Muldoon is no longer a party to this appeal, we do not discuss the facts related to his claims. 3 Appellate Case: 23-8014 Document: 136-1 Date Filed: 04/16/2025 Page: 4

Later that month, another minor, M.R., also came forward with sexual assault

allegations against Rosen. M.R. reported that, while at Rosen’s house one night, Rosen

physically dragged M.R. into his bedroom with his arm around her neck, took her phone,

locked the door, and assaulted her. In an interview with TCSO Deputies David Hodges

and Clayton Platt, M.R. also identified two other individuals who were present the night

of the alleged assault, at least one of whom she claimed saw and overheard parts of the

assault.

Rosen was arrested for first-degree sexual assault against I.U. and M.R. in

December 2019—ten days after he turned eighteen. Clark Allan, a prosecutor for the

Teton County Prosecutor’s Office (“TCPO”), later stated that “some investigators

expressed that they wanted to wait to file the case until after [Rosen’s eighteenth]

birthday.” R. at 28. Despite waiting over two months to arrest Rosen, none of the

investigators interviewed either of the two alleged witnesses to M.R.’s assault.

Additionally, during the investigation, Deputy Bommer repeatedly made disparaging

comments about Rosen, calling him “creepy” and comparing him to Jeffrey Dahmer, and

he likewise expressed that investigators waited to arrest Rosen until he was eighteen so

that they “could charge him as an adult.” Id. at 31–32.

At some point during his prosecution, Rosen learned that I.U. had also possibly

been abused by a local physical education (“PE”) teacher. The same TCSO officers

investigated the PE teacher as had investigated Rosen, but they did not pursue the

investigation to the same extent. Deputy Bommer—who knew the PE teacher personally

through coaching football—did not speak with I.U. about the matter until months after he

learned about it. Indeed, neither Deputy Bommer nor any other TCSO investigator ever

conducted interviews regarding the PE teacher’s conduct. Deputy Bommer later agreed

that he had probable cause to arrest the PE teacher, but he never did so.

The TCPO eventually dropped all of the charges against Rosen.

B.

Like Rosen, Crothers became the target of sexual assault allegations in 2019. One

evening, Crothers—who was then fifty-two years old––became “very intoxicated” while

at a bar. R. at 33. When he got home, Crothers discovered that his seventeen-year-old
