Do You Know...
You can't "unfound" a case that doesn't involve a crime? Unfounded means either:
1) The reported crime was determined not to involve an actual crime. In other words, your report may be titled a crime but its status is changed to unfounded because the investigation determined it actually was not a crime.
2) The reported crime happened outside of your jurisdiction.
By leaving the report titled as a crime, you are showing that your agency documented what was reported to it but have verified a crime didn't happen (and you're not leaving room for accusations of cooking the books).
If you are initiating a report to assist another agency, then an AOA is appropriate.
