Gov. Jay Nixon has appointed Mary E. Weston, of Hermann, as Gasconade County prosecuting attorney.
The position became vacant upon the appointment earlier this month of former Prosecuting Attorney Ada Brehe-Krueger as associate circuit judge.
Weston, a Republican, has served as the assistant prosecuting attorney for Gasconade County since 2005 and also operates a private law practice in Hermann.
She previously was assistant general counsel for the Missouri Public Service Commission, as well as a program analyst for the U.S. Department of Energy.
