CAMP PENDLETON, Calif. — A Marine from Fairfax County, Va., on his second tour in Iraq has died from injuries he sustained during fighting, the Defense Department said.

First Lt. Alexander E. Wetherbee, 27, died Sunday from injuries received due to enemy action in Iraq’s Anbar province, Camp Pendleton military officials said in a news release Monday.

Officials at the base declined to give any additional detail about what caused Wetherbee’s death, but said he was an assault amphibious vehicle officer assigned to the 3rd Assault Amphibian Battalion, 1st Marine Division, I Marine Expeditionary Force.

Wetherbee joined the Marine Corps in December 2001.

The Washington Post said a family member reached at the home of Wetherbee’s parents in McLean declined to be interviewed, saying only: “He was a wonderful young man, very loving. This is a terrible time for us.”
