This whole thing seems like a non-issue. Especially as it is being reported by the local paper. Many times these small cities are trying to lobby for a control tower, and sensationalizing something like this is a good way to try and get FAA funding for a control tower. From what I read it sounds as simple as:
1) Landing aircraft canceled IFR on approach.
2) Departing aircraft received IFR release.
3) Departing aircraft took runway
4) Landing aircraft performed Go Around.
It isn't like this sort of thing never happens t controlled fields either.
Sounds like the only issue is the lack of comm. or late comm. on the CTAF.
