DENVER (AP) — Colorado Sen. Mark Udall says officials responsible for mishandling remains of Americans killed in Afghanistan should be fired, put on trial or both.

Udall said Thursday he was horrified by Air Force revelations that a military mortuary twice lost body parts of war dead shipped home from Afghanistan.

Udall, a Democrat, is a member of the Senate Armed Services Committee.

The Air Force operates the mortuary in Dover, Del. Three mortuary supervisors have been punished but no one was fired.

Defense Secretary Leon Panetta has ordered a review of the mortuary. Panetta’s spokesman has said additional disciplinary action is possible.

Gen. Norton Schwartz, the Air Force’s top general, told Congress on Thursday that he takes personal responsibility for the incidents.
