Mo Brings Plenty, known for his role in the popular series Yellowstone, has expressed deep frustration over the lack of progress in the investigation into his nephew Cole Brings Plenty’s death. The actor’s killer remains unidentified, and Mo is calling for renewed efforts to solve the case.

In an interview with The Hollywood Reporter, Mo, who is currently featured alongside Luke Grimes in the Yellowstone spinoff Marshals, shared his concerns. At 56, he is particularly troubled by the unresolved nature of the case, which involves his nephew, Cole, who appeared as shepherd Pete Plenty Clouds in the Yellowstone spinoff 1923.

Cole’s untimely death at 27 has been widely covered in the media over the past two years, yet the case remains unresolved. Mo describes the lack of a thorough investigation as “heartbreaking,” criticizing the authorities for dismissing the case without adequate inquiry.

“To have his murder deemed as having ‘no foul play’ without a proper investigation is deeply disheartening,” Mo remarked in his Sunday interview. He underscored the disappointment felt within his community, emphasizing, “As taxpayers, we deserve the same diligence and commitment from law enforcement as anyone else.”

‘For his murder to go uninvestigated, and for it to be written off as “no foul play,” because they didn’t want to invest anything into it? It’s heartbreaking,’ Mo stated in the Sunday interview.

‘Because we’re taxpaying people as well. So for them to not work for us, no different than how they work for anyone else is pretty sad.’

He also shared that Cole meant a lot to him as he ‘was my nephew, but he was like a son to me.’

Mo claimed that police have not put ‘much effort into’ looking into Cole’s death.

‘They weren’t even really looking for him. They were hunting him,’ he told the outlet. ‘They weren’t searching for him.’

A warrant was issued for Cole’s arrest in March 2024 after he fled the scene of an alleged domestic violence case with a young woman.

Mo and his Yellowstone costar Cole Hauser asked for the public’s help to locate the young actor as he was deemed a missing person.

After leaving his apartment building early March 31, 2024, the actor, driving his white Ford Explorer, drove 20 miles to a Kwik Shop gas station in Baldwin City. He then drove to another gas station in rural Gardner, where he stopped in the TA Express minimart off Homestead Lane.

A manager there told DailyMail.com that Cole showed up before dawn, fidgety and appearing distressed, bought some groceries and left.

His SUV was found a few hundred yards away, parked deep into a construction site, out of public view, near a wooded area.

A worker at the site told DailyMail.com that one of the crew members noticed the vehicle early Friday, April 5, peered inside and saw blood. They called police, who found the body a short distance away.

Detectives have questioned people at the apartment building, the two gas stations and the construction site, telling several people that this was a suspected suicide.

After a four-day search, Cole’s body was found April 5, 2024, 28 miles away in Edgerton, Kansas, near a construction site where his vehicle was abandoned.

A cause of death was not released. Cole was buried in a traditional Sioux ceremony in his native South Dakota.

Lawrence Kansas Police Chief Rich Lockhart announced authorities found no evidence of foul play.

‘None of us could have imagined this outcome,’ Lockhart shared at the time.

‘I learned through this series of events that our Police Department must work harder to increase trust with our Native American community members.

‘Through meeting with Cole’s family members and members of our Native American community, I clearly see that we are not where we need to be in partnering with a community that is very important to Lawrence’s history and to its current culture.’

He continued, ‘It’s my hope that future bridges we build and partnerships we form between our Native American community and our police department will create a relationship that will not only increase trust and understanding but will also be a model for other communities.’

He finished with: ‘There are a lot of families such as mine that are going through this right now, and we still have a lot of unanswered questions.

‘Because I saw his body, I saw the evidence that is there, that someone caught him. So for them to say that there was nothing, I can’t believe that. I still can’t.’
