A U.S. Army tank company commander accused of murdering a man in Iraq went before a military court Wednesday for a fresh round of hearings to determine whether he should be court-martialed. Capt. Rogelio M. Maynulet is accused of killing a driver for cleric Muqtada al-Sadr while on patrol May 21 near Kufa, south of Baghdad. He denies the charges of murder and dereliction of duty. Testimony opened with an Army neurosurgeon from Walter Reed Army Medical Center in Washington, D.C., but the officer hearing the case, Maj. Michael J. Fadden, immediately sent reporters out of the courtroom, saying the testimony might include classified information.
