BAGHDAD — An American soldier has been killed and three others were wounded in a helicopter crash in northern Iraq, the U.S. military said.

Staff Sgt. James R. Patton, 23, assigned to the 3rd Battalion, 75th Ranger regiment at Fort Benning died from wounds sustained in the crash.

The UH-60 Black Hawk went down April 18, the military said. The cause is under investigation, but it is not believed to have been due to enemy fire, the military said in a short statement.

An Iraqi army officer from the area said the helicopter went down amid rainy and windy weather near Saddam Hussein’s hometown of Tikrit. Another Iraqi army officer said the helicopter crashed in the Al-Mahzam area, about 12 miles north of Tikrit.

They both spoke on condition of anonymity because they were not officially authorized to discuss the case.
