(Updates with new quotes) HILLA, Iraq, May 23 (Reuters) - The half-naked body of one of three missing U.S. soldiers was found on Wednesday in the Euphrates River in the town of Mussayab south of Baghdad, police said. The U.S. military said it was investigating reports that a body had been found in a canal in the area. Hilla police spokesman Captain Muthanna al-Maamouri said there were bullet wounds to the torso and head of the body, which was wearing U.S. Army-issue pants and boots and had a tattoo on the left arm. Maamouri said the body had been turned over to U.S. forces. Thousands of U.S. and Iraqi troops have been scouring farmlands through an area south of Baghdad known as the "Triangle of Death" since an ambush on May 12 in which four U.S soldiers and an Iraqi interpreter were killed. Three soldiers were reported missing after the attack. The al Qaeda-led Islamic State in Iraq has said it abducted them but has given no proof that they are still alive. A police officer in Mussayab, 60 km (40 miles) south of Baghdad, who declined to be named, said the body had been found after a tip-off from residents. A river patrol police officer in Mussayab who said he helped recover the body said the man appeared to have been killed about a week ago. His head showed signs of torture. General David Petraeus, the commander of U.S. forces in Iraq, said last Friday he believed at least two of the three missing soldiers were still alive.
