I am seeking a police sergeant, specifically one from a smaller town (Cuyahoga Falls, Ohio) and not a big city (such as New York, Chicago or Miami). I mainly need to know what their duties would be in a criminal investigation, and also if there is any reason that they would be on the road pulling over speeding cars. Also, what would the promotion procedure from Sergeant to Lieutenant be, and how long would it be before a Sergeant is offered this promotion?
