I reported sexual misconduct on my father someone about what he did to me when I was a child. It happened in another country and it had continued in the US for a while. I made the report when I was 18 years old. There were no arrest made, only a report was filed. I did not want my family to split apart.
Unless there was a determination made by an agency then he has no record to report.
