OP deleted
their own question within minutes of me answering it. I did flag it as well. The case is a bit unusual given that the OP had made a non-trivial discovery in a special case that turned out to be crucial. I don't quite understand why they would want to cover their tracks in such a case? We may have had similar occasions in the past, but I'm not sure how we handled all those. This is likely just a misunderstanding.
