LAS VEGAS – A grand jury in Nevada has again indicted Nathan Chasing Horse for sexually abusing Indigenous women and girls for decades, reviving a sweeping criminal case against the former “Dances with Wolves” actor.

The 21-count indictment unsealed Thursday in Clark County District Court, which includes Las Vegas, again charges the 48-year-old with sexual assault, lewdness and kidnapping. It also adds felony charges of production and possession of child sexual abuse materials.

It comes after the Nevada Supreme Court in September ordered the dismissal of Chasing Horse’s original indictment, leaving open the possibility of charges being filed again. The court sided with Chasing Horse, saying in its scathing order that prosecutors had abused the grand jury process.

Clark County District Attorney Steve Wolfson quickly promised to file another indictment.

The initial 18-count indictment accused Chasing Horse of more than a dozen felonies. He had pleaded not guilty.

His attorney, Kristy Holston, had also argued that the case should be dismissed because, the former actor said, the sexual encounters were consensual. One of his accusers was under 16, the age of consent in Nevada, when the abuse began, according to the indictment.

Neither Wolfson nor Holston immediately responded Thursday to requests for comment by phone or email.

Best known for playing the character Smiles A Lot in the 1990 film “Dances with Wolves,” Chasing Horse was born on the Rosebud Reservation in South Dakota, home of the Sicangu Sioux, one of the seven tribes of the Lakota Nation.

After starring in the Oscar-winning film, authorities said, he presented himself as a self-proclaimed Lakota medicine man while traveling across North America to perform healing ceremonies.

He is accused of using that position to gain the trust of vulnerable indigenous women and girls, lead a cult and take underage wives.

Chasing Horse’s arrest last January reverberated throughout Indian Country and helped authorities in the United States and Canada corroborate long-standing allegations against him, leading to more criminal charges, including on the Fort Indian Reservation. Peck in Montana. Tribal leaders had banished Chasing Horse from the reservation in 2015 amid allegations of human trafficking.

He has remained jailed in Las Vegas since his arrest.

When the Nevada Supreme Court ordered the dismissal of Chasing Horse’s indictment, the justices said they were not evaluating his guilt or innocence and called the allegations against him serious. But the court said prosecutors improperly provided the grand jury with a definition of harassment without expert testimony, and faulted them for withholding from the grand jury inconsistent statements made by one of his accusers.

Chasing Horse’s legal troubles have been developing as lawmakers and prosecutors across the United States are channeling more resources into cases involving Native women, including human trafficking and murders.
