A retired Oklahoma doctor is appealing his prison sentence for illegally distributing prescription drugs through an Internet pharmacy.
    Wilbur D. Hilst is claiming federal prosecutors coerced his guilty plea when they offered to dismiss charges against his cancer-stricken wife in exchange for it.
    U.S. District Judge Wesley Brown on Friday granted a request by the 76-year-old Hilst to remain free pending his appeal. He was sentenced to 33 months in prison earlier this month.
    The U.S. attorney’s office declined to comment, saying it would respond in court filings.
