On April 7, 2008, Russell Dean Landers had his sentence extended by 15 years for attempting to extort his release from prison. He and two other inmates at the federal prison in El Reno, Oklahoma had demanded millions of dollars from officials for the use of their names, which they claimed were "copyrighted". They were found guilty of "conspiring to impede the duties of federal prison officials and extortion in (their) efforts to gain release from prison by making financial demands on prison staff and attempting to seize their property."
