MILWAUKEE (WTAQ) - An assistant police chief in Milwaukee starts a high-ranking position Monday in the state Justice Department.

Patrick Mitchell becomes the new deputy administrator of the state’s Division of Criminal Investigation.

He joined the Milwaukee police force in 1985 as an officer. He had been an assistant chief under Ed Flynn for about a year-and-a-half.

Mitchell replaces Dave Matthews, who was promoted in October to a division administrator in the Justice Department.
