A new interim chief for the Aurora Police Department won't likely be announced until next week. Current Chief Nick Metz is retiring next week, and his temporary replacement is also leaving the force. Deputy Chief Paul O'Keefe announced this week that he wouldn't be taking the interim job, and would retire himself at the end of March. That move came after public outcry over the decision not to charge or fire an Aurora cop found drunk behind the wheel of his cruiser while on duty.
