The Oklahoma Court of Criminal Appeals rejected an appeal by Worley last month.
Friday, Worley went back to Sellers and asked that his sentence be reduced. Sellers agreed to reduce the sentence to 10 years with the rest suspended.
Under Oklahoma sentencing laws, Worley will be required to finish serving 85 percent of the 10 years before becoming eligible for parole, the judge indicated.
If the sentence had not been modified, Worley would have been required to serve 38 years before becoming eligible for parole, Duncan said.
If eventually released, Worley would remain on probation the rest of his life, the judge said.
