The man accused of killing two police guards at the Capitol looked anxiously to his lawyer for help Wednesday as a judge asked him such questions as his name and address.

Russell E. Weston Jr., bandaged and appearing frightened, was pushed into a federal courtroom in a wheelchair for his first appearance before a judge since the July 24 shootings to answer one federal murder charge, covering the deaths of both officers.He did not enter a plea, although he could have done so, and neither his lawyers nor prosecutors raised the potentially central issue of Weston's mental status. The defendant said he understood the charge against him.

Weston's lawyers, expected eventually to raise an insanity defense, would not discuss that strategy after Weston's brief ap-pear-ance in U.S. District Court.
