In December 2018, 14-year-old Henny Scott was found dead two weeks after she went missing near Lame Deer, Mont. In August 2019, 18-year-old Kaysera Stops Pretty Places was found dead four days after she went out with friends in Hardin, Mont. In January 2020, 16-year-old Selena Not Afraid was found dead along Interstate 90 three weeks after she was reported missing. All three girls lived in Big Horn County in southern Montana, which has one of the highest rates of missing and murdered Indigenous women and girls in the U.S.
Over three episodes, the docuseries Murder in Big Hornāstreaming Feb. 3 and on air starting Feb. 5 on Showtimeālays out how cases like these, and the grassroots organizing by the girlsā families, steadily drew attention to the growing Missing and Murdered Indigenous Women (MMIW) movement on a national scale.

āIf Henny was the spark, and Kaysera was the kindling, then Selena was the forest fire that just ignited across the media,ā says Luella Brien, the former general manager and editor of Big Horn County News, in one episode. āPeople wanted to know what the hell is happening in Big Horn County.ā

Big Horn County, with a population of roughly 13,000, sits on the Montana-Wyoming border and encompasses part of the Northern Cheyenne Reservation and most of the 2.2-million acre Crow Reservation. The final episode lists 82 MMIW cases in Big Horn County and its vicinity.
Not Afraid was last seen alive at the rest stop between Billings and Harden on Interstate I-90. The highway, which runs from Seattle to the East Coast, runs straight through the Crow Reservation and Billings, forming an artery for sex traffickers. In July 2018, 19-year-old Shacaiah Blue Harding also went missing from the Billings area. Months later, the series reveals, some of Hardingās peers came forward and said that she had been sold for drugs.
Harding and Not Afraid came from turbulent pasts. Hardingās mother was an addict and Harding lacked a stable home; she was later diagnosed with meth-induced schizophrenia herself. Not Afraid lost three siblings: her twin sister to suicide at age 11, her older sister to a hit and run, and her older brother to a police shooting.
Directors Razelle Benally (Oglala Lakota/DinĆ©) and Matthew Galkin donāt shy away from these truths. But they also make sure to let viewers know: Selena Not Afraid had a contagious smile, a dark sense of humor, and people wanted to be around her. Henny Scott was a tomboy who played football and basketball and adored her younger siblings. And Kaysera Stops Pretty Places was a fun-spirited, loving protector of her siblings, who was always there for her friends.

āIt was imperative for us to try to make them as well-rounded as we could,ā Galkin tells TIME. āBecause that was one of our first objectives in the series, is how do we pay respect to them and their families, and not treat them as one-dimensional, true crime characters?ā
Galkin previously directed the 2019 Showtime true crime series Murder in the Bayou, and the network approached him with the general idea for Murder in Big Horn the following year, after the New York Times covered Selena Not Afraidās case. He reached out to Bird Runningwater, then the head of the Sundance Institute Indigenous Program, and Sterlin Harjo, who would go on to create Reservation Dogs, and they directed him toward Benally, who had written for the noir Navajo Tribal Police investigation drama series Dark Winds, which premiered on AMC in 2022. Both directors wanted to veer away from true crime itself and instead use the tropes of the genre to examine the historical factors behind such high rates of missing and murdered Indigenous women.
āThese families deserve justice. They deserve answers,ā Benally says. āAnd Iām so less concerned about the general populace not having an answer, because these families wonāt, in a lot of these cases. And thatās something we should be angry about.ā
None of the cases covered in the docuseries wrap up neatlyāthe investigation into Selena Not Afraidās death was ongoing as of 2021. As the filmmakers dug into the stories, they followed a trajectory similar to that faced by the victimsā families: police stonewalled them by refusing to communicate.
āThereās a lot of biases and discrimination that we had to combat that was pre-existing in Big Horn County, amongst specifically law enforcement and government and agencies, against Native peoples,ā Benally says. āWhen you reduce a person down to something like that, it allows for people to disregard the importance of these human lives.ā

The Big Horn County Sheriffās Office did not respond to the production teamās requests for comment. āThe sheriffās office in Big Horn County would have retribution against you if you spoke up,ā Eric Winburn, the former undersheriff of Big Horn County, says in the show. āTheyād just make your life hell there. Youād have to move.ā
The directors discovered that most of the cases were never thoroughly investigated. āThat is as eye-opening as the whodunit aspect,ā Galkin says.
Big Horn Countyāand Indian Country in generalāis a jurisdictional vortex. On county land outside of the reservation, the Big Horn County Sheriffās Office has jurisdiction. On tribal lands, the FBI and the Bureau of Indian Affairs (BIA) hold authority. But the BIA canāt exercise criminal jurisdiction over non-Natives when they commit crimes on tribal land. And the FBI often waits until it is āinvited inā by local authorities to open investigations.
āTo figure out who has jurisdiction at any given time, you have to know: who is the victim? Are they Indian or not? Who is the perpetrator? Are they Indian or not? Where did the crime occur? On Indian land or not?ā Lucy Rain Simpson, the executive director of the National Indigenous Womenās Resource Center, says in the show. āWhen it comes to violence against Native women, when it comes to missing and murdered situations, oftentimes we donāt know.ā
Murder in Big Horn also delves deep into two tough issues: the continued impact of the damning history of colonization on Native peoples and the existence of Native-on-Native violence. Benally grappled personally with how to address the latter, and how her community would receive it.
āWhen you take away the things that make a person: language, land, responsibilities, people become lost and they donāt know what to do with themselves,ā Benally says. āAnd so as a result of colonization, you get the effects of that, which includes addiction, abuse, violence.ā
āAnd itās hard to talk about, but if weāre talking about all these other things,ā she continues, āthen we have to be real with ourselves as a people and see that we need to start taking accountability and responsibility if we want things to change.ā
