This sounds like the statement was made privately, not an official complaint or a public statement or posting. This sounds like the OP has insider knowledge they want to make public, and indeed have done so by posting here. I expect from the details here, someone local would be able to piece together the identities. We have the state, we know it’s a trainer from a barn where another trainer is currently under SS investigation, it’s a smaller horse community.
So I think OP has achieved their purpose without actually writing an article.
