OMAHA, Neb. (AP) — The FBI has named a 20-year veteran of the bureau as the new special agent in charge of the Omaha Field Office, overseeing Nebraska and Iowa.

A news release Wednesday from the FBI named Kristi Koons Johnson as the new special agent in charge of the two-state office. She had been serving as chief of a section that investigates transnational criminal organizations at FBI Headquarters in Washington.

Johnson joined the FBI in 1999 as a special agent in Chicago, where she spent a decade investigating organized crime and public corruption. She was promoted to supervisory special agent and led a public corruption squad in 2007. In 2010, Ms. Johnson was named the chief division counsel for the Omaha Field Office and promoted three more times before her latest assignment.

Johnson holds a bachelor’s degree from Michigan State University and a law degree from the University of Detroit-Mercy.
