MUSKOGEE, OKLAHOMA - The United States Attorney’s Office for the Eastern District of Oklahoma, announced today that William Clayton Brown, age 39, of McIntosh County, Oklahoma was found guilty by a federal jury of Murder in Indian Country, in violation of Title 18, United States Code, Sections 1111(a), 1151, and 1153. The jury trial began on Tuesday, July 5, 2022, and concluded on Thursday, July 7. Based on the jury’s verdict, the Defendant is facing a mandatory minimum sentence of life imprisonment.
