Rock County Sheriff Troy Knudson says his office is working to confirm a tentative DNA identification of a body known as John Clinton Doe.
The body of the young man was found along Turtle Creek in the town of Bradford in 1995.
The body, clad in a T-shirt from the heavy metal band Venom, has never been identified.
The DNA Doe Project announced a tentative match last week.
Knudson says the sheriff’s office cannot rely on an analysis by a private entity and will get its own analysis done, which could take some time.
