Russell Dean Landers – 11 years, 3 months; later extended by 15 years (see below). Died in prison on April 10, 2021, aged 69 Daniel E. Peterson – 15 years (see below). On April 7, 2008, Russell Dean Landers's sentence was 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 prison 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." On April 6, 2010, Daniel E. Petersen was sentenced to serve additional time for filing bogus liens against three federal judges from prison, including the judge who had originally sentenced him to prison. In 1996, Petersen had been sentenced to 15 years in federal prison, after being convicted on 19 counts, including bank fraud and armed robbery. While he was serving his sentence in a federal prison in Minnesota, Petersen devised a scheme in which he would retaliate against those three judges. After an investigation, federal prosecutors found that Petersen had invented a company that supposedly held assets that included a $100 trillion default judgment against the United States. He then sold "shares" of the phony company to fellow inmates and others. He claimed that these shares were backed by "redemption certificates", which would be redeemed when the "judgment" was collected. The judgment which he referred to came from a self-created court, after then-Secretary of State Madeleine Albright declined to respond to his demands. He demanded $100 trillion, as well as $1 billion per day in interest, because he believed that the United States government was unlawfully confining him. Petersen followed up by filing liens against property which was owned by the three federal judges. He also offered bounties for the arrest
