The U.S. military has released the name of the second officer shot to death Saturday at the Afghan Interior Ministry in Kabul.

He is Army Maj. Robert J. Marchanti II, of Baltimore.

On Sunday the Pentagon released the name of the other officer: Air Force Lt. Col. John D. Loftis, 44, of Paducah, Ky. He was assigned to the 866th Air Expeditionary Squadron in Kabul.

Navy Capt. John Kirby, spokesman for the U.S.-led international military coalition in Afghanistan, said Monday that the gunman was still at large and that authorities are undertaking an "active search" to find him.

Almost immediately after the shootings, the top U.S. commander in Afghanistan, Gen. John Allen, withdrew all coalition advisers from Afghan ministries. Kirby said Allen is not yet ready to send them back.
