THE DISTRICT

Girl arrested in slaying: Police arrested a 15-year-old girl Sunday night on charges stemming from the fatal stabbing of a man in his apartment in the 1300 block of Morris Road SE.

Douglas Mayo, 26, was stabbed about 10:15 p.m. and was pronounced dead 30 minutes later at Washington Hospital Center. D.C. police said the juvenile suspect, also from Southeast Washington, stabbed Mayo during an altercation. She was charged with first-degree murder while armed but was not identified because of her age.

Official placed on leave: The D.C. police official in charge of internal investigations has been placed on administrative leave because of a "non-duty-related" matter, said Sgt. Joe Gentile, a police spokesman.

Peter Newsham, one of six assistant police chiefs, is a veteran commander who most recently had supervised the Office of Professional Responsibility, which handles internal affairs and use-of-force investigations. Gentile declined to say what led to the department's action or to provide other details.

VIRGINIA

Halt to execution sought: Mir Aimal Kasi, the Pakistani who is facing death for the 1993 shootings outside CIA headquarters that left two people dead and three wounded, has asked the U.S. Supreme Court to stop the execution, his attorney said yesterday.

Kasi, who is scheduled to be executed Nov. 14, has exhausted all appeals in lower courts and only the U.S. Supreme Court or Virginia Gov. Mark R. Warner (D) could intervene.

Kasi's attorneys have argued that their client was improperly detained in Pakistan by FBI agents who returned him to Virginia for trial. Kasi opened fire outside CIA headquarters in Langley on Jan. 25, 1993, in what he described in court as a response to America's "wrong policy" toward Muslim countries.
