OSAN AIR BASE, Republic of Korea -- A "dead body" and other "evidence" was placed around the Osan AB Air Force Office of Special Investigations compound for a forensic exercise April 29. Osan’s AFOSI detachment took the opportunity to not only practice their own skills, but also teach and learn from local Republic of Korea air force members and Korean police investigators.
