SIOUX FALLS, S.D. — Three Sioux Falls men are facing federal racketeering and firearms charges after prosecutors said they tracked down a victim at a local business and shot him multiple times in an attempted gang-related killing earlier this year.
The U.S. Attorney’s Office for the District of South Dakota said a federal grand jury indicted Nathan Carlos Hernandez, 20, Sebastian Michael Waters, 19, and Tino Sage Roubideaux, 29, on charges including conspiracy to murder in aid of racketeering, attempted murder in aid of racketeering, assault with a dangerous weapon in aid of racketeering, a firearm offense tied to a crime of violence, and possession of a firearm by a prohibited person.
Prosecutors allege the three men were members of the Gangster Disciples, which authorities described as a gang operating in Sioux Falls and elsewhere whose members and associates committed violent acts, drug dealing, and firearms trafficking. The indictment says gang members gained respect and status through criminal activity, including violence against people seen as threats, and that one of the gang’s purposes was to keep victims, rivals, and community members in fear.
According to the charging document, Hernandez, Waters, and Roubideaux conspired to kill a person and then found that victim at a Sioux Falls business on Jan. 4, 2026, where they allegedly tried to murder him by shooting him more than once with two firearms. Federal prosecutors said the attack was meant to help the defendants maintain or increase their positions within the gang.
All three men have pleaded not guilty in federal court, and each was ordered held in U.S. Marshals custody pending trial. Prosecutors said the most serious firearm count carries a mandatory minimum sentence of 10 years and up to life in prison if there is a conviction, and the case is set for trial on Oct. 26, 2026.
Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
