The discovery of a man's body found Thursday morning at Selfridge Air National Guard Base in Macomb County has the Michigan State Police asking for the public's help as they attempt to identify him. Officials say the body was found on the ground and note there does not appear to be any foul play involved. The man is described as between the ages of 20 and 30 and did not have any identification on him. Selfridge officials say the man was not a member of the military nor was he an employee at the base. An exact cause of the man's death has not been determined as the investigations continue.
