Nine persons were indicted here yesterday by a federal grand jury on charges of falsely representing themselves as discharged servicemen and servicewomen and collecting about $112,000 in unemployment compensation in 13 months.

According to federal prosecutors, part of the group charged here yesterday obtained another $125,000 in southern California using the same scheme.

According to the indictments, the defendants obtained blank Defense Department forms, known as DD 214s, which stated that they had been discharged from the military. Several of the defendants are charged with filing forms under a variety of aliases with the District of Columbia Unemployment Compensation Board.

The scheme was discovered when a bank cashier became suspicious after several checks made out to different individuals were deposited to the account of one of the defendants.

An official of the Labor Department, which approves unemployment compensation forms, said that no verification had been made with the Defense Department "simply because we did not have the procedure" to make such a check. The official, Robert Schaerfl, director of the office of program management, said a procedure has been developed "to prevent a recurrence."

The defendants charged yesterday were Earl T. Jordan, 26, of 3415 Glenn Dr., Suitland; Willie G. Jordan, 27, address unknown; Barbara Duckett, 21, 3307 Mt. Calvert Rd., Upper Marlboro; Joseph M. Fenwick, 27, 20001 Shipley Terrace SE; Robert Goldston, 34; Leroy Kearney Jr., 30, 1412 Iverson St., Oxon Hill; Anthony Medley, 22, 4701 Benning Rd. SE; Robert L. Williams, 31, 4614 Livingston Rd.SE, and Margaret Rice, 32, 1307 Iverson St., Oxon Hill.
