Mark Swanner is a CIA interrogator. He worked at the Abu Ghraib prison in 2003. A prisoner named Manadel al-Jamadi died during one of his interrogations while his wrists were tied behind his back.[1][2]
Media reports interpreted this to mean he was tied up in strappado style but guards told CIA investigators that Jamadi was given enough slack to kneel or stand.[1][3]
Swanner claims that he did not harm al-Jamadi and that the death was accidental and unexpected. He has not been charged with a crime.
