Federal prosecutors announced guilty pleas in two separate violent assault cases in the Eastern District of Oklahoma, involving incidents in Hughes and Seminole counties that occurred within tribal reservation boundaries. The cases, handled in federal court due to jurisdiction in Indian Country, involve serious allegations of assault with dangerous weapons and firearm-related offenses.

According to the indictment, the assault occurred on August 17, 2025, in Hughes County, within the boundaries of the Muscogee Nation Reservation. Investigators alleged that Ramirez intentionally threw boiling water onto the victim’s back, causing severe burns.

The case was investigated by the Federal Bureau of Investigation, the Muscogee Nation Lighthorse Tribal Police Department and the Okemah Police Department. U.S. Magistrate Judge Jason A. Robertson accepted the guilty plea and ordered the completion of a presentence investigation report. Ramirez will remain in custody of the United States Marshals Service while awaiting sentencing, which will be determined by a U.S. District Court Judge after reviewing federal sentencing guidelines and statutory factors.

In a separate federal case, Demontrae Davion Rogers, 20, of Wewoka, and Damarion Hiawatha Nichols, 21, of Moore, pleaded guilty to multiple charges stemming from assaults that occurred on April 2, 2024, in Wewoka, located in Seminole County within the Seminole Nation Reservation.

Federal authorities alleged that Rogers assaulted one victim while brandishing a firearm, and that Nichols assaulted four separate victims during the same incident. The investigation was conducted by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Seminole Nation Lighthorse Police and the Seminole County Sheriff ’s Office.

U.S. Magistrate Judge D. Edward Snow accepted the guilty pleas for Rogers and Nichols and ordered pre-sentence investigation reports.
