On August 15, 1978 Jackson County Sheriff’s Office responded to a call to investigate human remains found by loggers in a remote wooded area near the Village of Warrens, Township of Knapp, Jackson County, Wisconsin. Search of the area by officials resulted in the recovery of a skull, lower mandible, and vertebra. The results of a limited autopsy indicated the deceased was a white male between the ages of 28 and 52. A silver-colored ‘Medi-Stud’ brand earring, normally used by piercing salons, was also discovered near the remains, leading investigators to theorize the deceased had at least one pierced ear. Any other remains were never located. The manner of death is recorded as ‘Presumed Homicide’.

DNA Doe Project Status: Research in progress
