One of the men believed to be a captor of Staff Sergeant Matt Maupin has been killed in Iraq.
The U.S. military has confirmed Hajji Hammadi was killed with another armed insurgent on November 11 during a raid by U.S. forces in Baghdad's Mansour neighborhood.
Staff Sgt. Maupin's father, Keith Maupin, tells 9News Hammadi is the tall figure seen on the left hand side in a video showing his son in captivity that aired on Arab television network Al-Jazeera.
"I feel satisfied in the fact that justice was done and this guy is held accountable. He not only did this to Matt, but there were other plots he was involved in. His plotting is done," said Keith Maupin.
The military says Hammadi was linked to Maupin's abduction in 2004.
Maupin, originally from Batavia, was finally laid to rest earlier this year after his remains were recovered.
Hammadi is also thought to be the mastermind behind an attack in Anbar on June 26 of this year that killed three U.S. Marines, two interpreters and more than 20 Iraqis.
Keith Maupin says he was informed earlier this year that several others of his son's captors had been caught and would be placed on trial in Iraq.
