Another man has been charged in the death of a 28-year-old man that occurred nearly 20 years ago.
Fayetteville television station KHOG reports 56-year-old Ricky Dority is charged with first-degree murder and robbery in connection with 28-year-old Mitchell Nixon's death in 1997.
Authorities found the victim's body near Sallisaw, Okla. Agents discovered a bloody rock next to Nixon's head.
Rex Richard Robbins is also charged in connection with Nixon's death and has pleaded not guilty to the charges.
Dority is in a federal prison after he was convicted in 1999 for being a felon in possession of a firearm. Oklahoma prosecutors say he will be brought to the state to be arraigned for his new charges. It wasn't immediately clear whether Dority has an attorney.
