Hello I live in Oregon in a small rural town. I made a public records request for an incident that happened with our rural fire department. The city manager had the information that I requested in an envelope for me but unfortunately the city council decided to terminate him. Now the mayor is telling me that she doesn't have the information that I requested. I also did a records request through the rural fire department. What can I do if the city and the fire department isn't giving me my public records request.
