On August 15, 1978, members of a logging crew located human remains in a remote wooded tract of county forest land approximately 100 yards south of Keys Rd about ¼ mile east of the intersection of Fish Creek Rd in Knapp Township, Jackson County, Wisconsin.
The remains were estimated to have been located in the area for several months prior to their discovery. The manner of the subject’s death is believed to be homicide.
The remains are identified as Dennis R. McConn DOB 07/27/1947 who went missing from
Kenosha, WI in 1977 at the age of 29. McConn’s next of kin have been notified.
The Jackson County Sheriff’s Office is seeking the public’s help as the investigation into
McConn’s death continues. Anyone with information on why McConn would have been in
Jackson County, or any other knowledge of this case should contact the Jackson County Sheriff’s
Office Crime Stoppers Line at 800-228-3203 Ext. 199. The DNA Doe Project is a non-profit volunteer organization formed to identify unidentified deceased persons using forensic genealogy.
