Military: At Least One GI Beheaded

Remains of Two Soldiers To Arrive In U.S. Wednesday For DNA Testing

(CBS/AP)  Menchaca's mother, Maria Vasquez, had already heard the reports when a member of the Army's casualty assistance office arrived at her Brownsville home Tuesday morning. She was sobbing when she answered the door of her home, accompanied by her niece, Felipa Gomez.

"She's hanging in there," and still holding on to hope that Menchaca will make it back alive, Gomez said. "She might be frightened, but she won't show it."

Vasquez later issued a statement written in Spanish that said, "I am against the war and I feel very hurt by what has happened to my son."

Ken MacKenzie, an uncle of Manchaca, lashed out at the U.S. government Tuesday morning, saying it did not do enough to find the men and keep them safe.

"I think the U.S. government was too slow to react to this. They should have had a plan in place," said MacKenzie, on NBC's "Today" show. "Because the U.S. government did not have a plan in place, my nephew has paid for it with his life."

"I don't want people to forget," said Mario Vasquez, another uncle of Menchaca. "I don't want them to think that they were just two more soldiers. I want them to find the people that did that and make them pay."

The discovery of the remains followed a massive search effort by some 8,000 Iraqi and U.S. troops after the two men went missing Friday near the town of Youssifiyah in the volatile Sunni Triangle south of Baghdad.

U.S. Maj. Gen. William Caldwell said one U.S. soldier died and 12 others were wounded during the search effort, while two insurgents had been killed and 78 were detained as coalition forces received 66 tips, 18 that were considered worthy of follow-up.

The claim of responsibility was made in the name of the Mujahedeen Shura Council, an umbrella organization of five insurgent groups led by al Qaeda in Iraq. The group posted an Internet statement Monday claiming it was holding the American soldiers captive.

"We give the good news... to the Islamic nation that we have carried God's verdict by slaughtering the two captured crusaders," said the claim, which appeared on an Islamic militant Web site where insurgent groups regularly post statements and videos.

"With God Almighty's blessing, Abu Hamza al-Muhajer carried out the verdict of the Islamic court" calling for the soldiers' slaying, the statement said.

The statement said the soldiers were "slaughtered," suggesting that al-Muhajer beheaded them. The Arabic word used in the statement, "nahr," is used for the slaughtering of sheep by cutting the throat and has been used in past statements to refer to beheadings.

The U.S. military has identified al-Muhajer as an Egyptian associate of al-Zarqawi also known as Abu Ayyub al-Masri.

The killings would be the first acts of violence attributed to al-Muhajer since he was named al Qaeda in Iraq's new leader in a June 12 Web message by the group. Al-Zarqawi was killed in a U.S. airstrike on June 7.
