Colonel Michael Bumgarner (born 1959) has been a career officer in the military police of the United States Army. He is most noted for having been the commander of the Joint Detention Group, the guard force component of Joint Task Force Guantanamo, from April 2005 through June 2006, at the Guantanamo Bay detention camp. During this period there was a widespread hunger strike in 2005, which he helped end. On June 10, 2006 three detainees were found dead, in what the United States Department of Defense announced as suicides. Bumgarner had other assignments after Guantanamo and retired from the military in 2010.
