It is likely a voice repeater input for the local MOSWIN tower. Since you were close to the Sheriff's Office, you were likely picking up a radio accessing the system.
I confirm it's an input for the Dayton Site, even though it's slightly off, but could be overloading the adjacent frequency. So my guess is the same as bdzig.
Is one thing I don't like about the radio reference database and input frequencies for trunk systems, you can't search the database and find the inputs
