According to The Associated Press, Mr. Richmond killed a cow herder who had been detained along with the other men in an Iraqi village near Taal Al Jai that the Army raided on Feb. 28, 2004. The herder, Muhamad Husain Kadir, was handcuffed when Mr. Richmond shot him in the back of the head from six feet away as the man stumbled, The A.P. reported.
In his defense, Mr. Richmond, then 20, said that although he had not seen Mr. Kadir with a weapon, he thought that Mr. Kadir had been lunging to attack another soldier, adding that he didn’t know Mr. Kadir’s hands had been bound, according to the wire service.
In the Justice Department’s announcement on Monday, prosecutors said Mr. Richmond was among a group of about 10 people who traveled from Ohio to Washington D.C. to attend pro-Trump rallies planned for Jan. 6., when Congress was set to certify the results of the 2020 presidential election at the Capitol.
Investigators identified Mr. Richmond in several images and footage from the Capitol breach on Jan. 6, including on closed-circuit television footage and on video taken by officer body-worn cameras, according to an affidavit written by an F.B.I. agent filed with the criminal complaint in the U.S. District Court in Washington.
Mr. Richmond is seen in images filed in the complaint wearing a black helmet, goggles, shoulder pads and a state of Louisiana flag patch attached to a camouflage-pattern vest.
