Keokuk, IA – The Keokuk City Council has approved the first reading of an ordinance that would combine two ranks -- detective and sergeant -- into one for promotional exam purposes. Assistant Chief Tom Crew says this will help the department, which is relatively young in terms of age and experience. Now, there are six ranks for officers. They can take the promotion tests for ranks up to two above their current position. By combining the ranks of detective and sergeant, patrolmen will be able to test for captain while detectives will be able to test for assistant chief. The council could discuss making the salaries for detectives and sergeants equal in the future.
