I recently contacted Lance Krout, the investigator for this case. Here is his response.
"Yes we are aware and have looked into him in the past . He has family DNA is in Codis and our John Doe’s DNA is in Codis as well and no hits were confirmed with him. Also according to Namus his dental does not appear to match our victim as I believe Nobles does not have dental plate and our victim does. I have reached out to that Dept to confirm everything they have but have not heard back yet.
I hoping to double check the content I have on him with them and then put out on Namus as to a match for positive or not."
