NDN Collective founder and CEO Nick Tilsen's felony charges have been formally dropped about six weeks after his trial ended in a hung jury, according to court documents filed Monday.
Tilsen was indicted on charges he assaulted a Rapid City police officer in 2022. The case spanned several years and went to trial more than three years after the June 2022 incident.
After Tilsen's case ended in a mistrial in January due to the hung jury, prosecutors had 45 days to re-try Tilsen's charges – until Mar. 15 Because they did not do so, Tilsen has been officially cleared of the aggravated assault, simple assault and obstruction of a law enforcement officer charges.
"In this case, the facts were the facts, and they were all on video. This was not an aggravated assault from the beginning." – John Murphy, Nick Tilsen's lawyer
NDN Collective called the charges politically motivated and launched a petition demanding the release of Tilsen that received more than 22,000 signatures.
"I thank my elders, my people, my family, the ancestors, my attorneys and my team at NDN Collective for standing with me. These efforts have not slowed us down. We are stronger than ever, more strategic and re-energized for the path ahead. We will continue to exercise Indigenous self-determination and build collective power for all people and Mother Earth," Tilsen said Monday in a statement.
On Mar. 6, prosecutors filed a motion to prohibit public access to information in the court record, which would have sealed exhibits including body and dash cam footage from Tilsen's case to the public. Olivia Siglin, Pennington County deputy state's attorney, cited significant media attention and "inflammatory and incorrect" claims from NDN Collective that might sway potential jurors.
That motion was not ruled on by a judge before the Mar. 15 deadline.
"This case received significant public attention, but our decisions are not driven by public pressure or commentary," Lara Roetzel, Pennington County state's attorney, said in a statement. "They are grounded in the evidence, the law, and our obligation to exercise sound judgment on behalf of this community."
John Murphy of Rapid City, Tilsen's lawyer, told News Watch that he thinks the dropped charges indicate that prosecutors did not have the case to convict Tilsen. The jury was hung on a 10-2 in favor of acquitting him, Murphy said.
He said the case should not have been tried to begin with, echoing NDN Collective's statements that the charges were politically motivated.
"In this case, the facts were the facts, and they were all on video. This was not an aggravated assault from the beginning. So the fact that they didn't retry it, I applaud them because it would have just been more of a monumental waste of taxpayer dollars. However, the fact of the matter is this case should never have been prosecuted," Murphy said.
What is NDN Collective?
The Rapid City-based NDN Collective is a Native rights organization that focuses on campaigns and financial assistance programs related to Native American issues nationwide.
NDN Collective filed a federal civil rights class-action lawsuit accusing racism against the Grand Gateway Hotel in Rapid City in March 2022 after Connie Uhre, an owner of the hotel, threatened to ban all Native Americans from the hotel.

In December, a jury ruled the hotel's owners had been discriminatory and ordered them to pay $1 in damages, which NDN Collective had requested.
The organization is also known for its several funding and resource assistance programs, like its Community Self Determination grant and the NDN Fund, a loan program providing funding to various sectors of Native communities like renewable energy and housing.
