St. Louis (KSDK) -- The University of Missouri-St. Louis hired St. Louis Police Chief Dan Isom for its nationally ranked Department of Criminology and Criminal Justice.
Isom will be retiring on January 1, 2013. He made the announcement Monday during a press conference at his alma mater.
The department said Isom will spend his remaining time focusing on addressing crime in the city, finalizing plans for the new headquarters building and assisting in implementing any new changes for the department.
Mayor Francis Slay would not speculate on who would become the new chief. State law requires the St. Louis police chief be selected from within the department among the ranks of captain or above.
Speculation about the chief's future with the department has been swirling for weeks since a previous "Evening Whirl" article suggested he had been exploring other job opportunities.
NewsChannel 5's Ryan Dean was at a news conference last month when Chief Isom was asked point-blank if he was taking another job. He would neither confirm nor deny the reports.
Chief Isom has worked for the city police department for the past 24 years.
