Shelby resident William Flynn Walker, 49, who was indicted last October on seven counts of transporting minors across state lines and engaging in sex acts with minors, was sentenced in federal court last week to serve 27 years in prison without the possibility of parole.

Walker was also sentenced to 20 years in prison in Shelby County district court in April. Walker will serve the two sentences concurrently.

Walker was sentenced on charges that he transported three separate children seven times over state lines to commit sex acts with them between 1984 and 2004.

Assistant U.S. Attorney Jim Phillips confirmed Monday that Walker will also be required to pay $100,000 in restitution for his crimes.

Walker was arrested in Jefferson County, where he worked as a physician in Birmingham. He was also a co-founder of the Helena-based Evangel Christian School.

Upon his release from federal prison in 2033, Walker will be placed under supervised release by the state for the remainder of his life
