JACKSON — Celebratory social media posts tipped off authorities to a trio of Montana mountain lion hunters who illegally killed a tomcat in Yellowstone National Park.
Photos shared via Instagram, Snapchat and Facebook, including publicly accessible images, were deleted, but not before other hunters recognized the landscape and alerted game wardens. While pressing 19-year-old hunter Corbin Simmons about the incident during a Jan. 10 interview, Yellowstone special agent Jake Olson explained what led him to the case.
“You know, we ended up getting a lot of this information from a guy in Bozeman off of Facebook,” Olson said, “’cause you guys put a bunch of stuff on social media.”
The law enforcement ranger lectured the young hunter, explaining that free-running hound dogs giving chase to lions accidentally cross into Yellowstone with some regularity and the right thing to do when that happens is to report the incursion and leave the treed cat unscathed.
“Obviously, that’s where the major error occurred here,” Olson said. “You guys have to police yourself out there. You gotta do this right.”
He scolded Simmons for fueling anti-hunting sentiments and feeding calls for a no-hunting buffer zone around Yellowstone, where National Park Service policies prohibit killing terrestrial wildlife.
The above exchange comes from a transcript included in an investigation report that led to the conviction of Austin Peterson, Trey Junhke and Simmons, all either 19 or 20 years old and from Livingston, Montana.
Yellowstone officials publicized the case after it had been adjudicated in May, but park officials declined to make law enforcement officers available for an interview or answer follow-up questions about details in their press release. The News&Guide obtained investigation documents, which are public records, through a Freedom of Information Act request.

During separate interviews about a month after their hunt, the three men repeatedly got their stories crossways. They confused details like when they saw boundary posts, who shot at the lion and what color Peterson’s GPS screen displayed when the device supposedly malfunctioned.
Peterson told Montana warden Drew Scott that a faulty GPS showed “all white,” while Junhke claimed that it was “just pure black.” Another account passed to authorities claimed the screen went purple, and Junhke later amended his recollection to “purplish-black.”
Accounts also differed over who shot at the mature male lion, with Junhke initially denying discharging a firearm. State and federal law enforcement officers eventually ascertained that all three men fired at the tom, which was hit a total of eight times, according to the investigation.
After hounds initially treed the cougar, one of the men reportedly climbed the tree to “knock it out” so that the dogs could continue to give chase. Treed a second time on a hillside overlooking the Yellowstone River, the lion was shot in the chest with a Glock .45-caliber pistol. The animal jumped and was fired at again, but managed to run an estimated 80 yards before being shot and killed where it took refuge under a rock.
The hunters again told conflicting stories when asked where they killed the cat.
Initially, Peterson told authorities that they left the carcass at the kill site after skinning the animal and taking some meat and its skull. But Simmons told warden Drew Scott that they “took it,” leaving the remains in the Gallatin National Forest about 2 miles north of where the cat was killed.
While registering the lion with state wildlife officials in Bozeman, Simmons provided a township and range that was two and a half miles away from the true location of the kill.
A Facebook picture Peterson posted looking down into the Black Canyon of the Yellowstone convinced another mountain lion hunter that the trio illegally killed the tomcat in the park. After hearing from people who suspected that Peterson was in the park, the photo was deleted.
