U.S. Attorney Eric Melgren is stepping down from his prosecutor role on Thursday when he takes the oath to become the state's newest federal district judge.
Melgren served as U.S. attorney for nearly seven years and is replacing U.S. District Judge Monti Belot, who is taking senior status.
Veteran federal prosecutor Marietta Parker is taking over as acting U.S. attorney in Kansas. She will run the offices in Wichita, Topeka and Kansas City, where she is based.
Parker has been a federal prosecutor for 18 years, including time as assistant U.S. attorney in Missouri's Western District, where she served twice as interim U.S. attorney.
Melgren's appointment to the federal bench was confirmed by the Senate on Sept. 26.
