Charles Allen Rednose, 21, has admitted in federal court that he was responsible for a deadly stabbing that took the life of 26-year-old Kathryne Silverhorn near an Anadarko casino last November. Rednose pleaded guilty to assault resulting in serious bodily injury and voluntary manslaughter in Indian Country after prosecutors said Silverhorn, a mother of two from Anadarko, was attacked while trying to break up a fight. At sentencing, he could receive up to 25 years in prison and as much as $500,000 in fines.

Investigators say Rednose was part of a group that went to a casino near Anadarko on Nov. 6. Some in the group later left the casino to pick up a friend, and on the way back they reportedly saw Rednose walking along Highway 281. Two people stopped to speak with him, and what began as a roadside encounter quickly turned into a struggle. Officials say Rednose stabbed two people during the altercation, and Silverhorn later died from her injuries, according to KOKH.

Kathryne “B” Louise Silverhorn, 26, was remembered by loved ones as a dedicated mother and an active part of her community. She is survived by her daughter, Evelyn Iris Silverhorn, and her son, Eli Edwards III, according to Ray & Martha's Funeral Home.

Charges and Possible Prison Time

Rednose entered guilty pleas to assault resulting in serious bodily injury in Indian Country and to voluntary manslaughter in Indian Country. Prosecutors said a federal grand jury had returned an indictment in May, and the plea now moves the case toward a sentencing hearing. At that hearing, he faces a statutory maximum sentence of 25 years behind bars and fines that could total up to $500,000, according to KOKH.

Why the Case Landed in Federal Court

Violent crimes that occur on tribal lands, or that fall under the federal Major Crimes Act, can be prosecuted by the U.S. Attorney and investigated by the FBI. The bureau holds responsibility for many serious offenses in Indian Country. The FBI has highlighted initiatives such as Operation Not Forgotten, which is intended to boost investigative efforts and victim services in Indian Country cases, including additional support for offices in the Oklahoma City area, according to the FBI.

With the guilty plea now entered, the case moves into the federal sentencing phase. A date for that hearing has not yet been publicly announced, leaving Silverhorn’s family and the Anadarko community to navigate their grief as the court process continues.
