Two men and a woman who allegedly operated a fraudulent Spring-field-base appliance repair service were indicted by a federal grand jury in Alexandria yesterday on conspiracy and other charges.

The three persons accused of swindling Washington-area residents were identified as Robert Eugene Early, 38, of Arlington; Reginald Glenn Moffitt, 27, of the District of Columbia, and Nancy O'Neal 22, of Honolulu.

The 13-count indictment did not state how much money was gained through the allegedly fraudulent scheme, but there were indications it may have amounted to as much as $25,000 to $30,000.

According to the indictment, the three suspects set up a business called Appliance Underwriters in 1978, based in the Brookfield Plaza Shoppng Center in Springfield.

The business, according to the federal charges, purported to provide home appliance repairs in exchange for one-year or two-year contracts. A one-year repair contract cost $105 and the fee for a two-year service agreement was $191, according to the indictment.

Federal prosecutors alleged, however, that the company "failed to provide" the repair services and "did not return the fees and monies collected from clients." The prosecutors alleged that the company also fraudulently charged fees against homeowners' credit cards without the homeowners' authorization.

The indictment charged Early, O'Neal and Moffitt with one count of conspiracy three counts of mail fraud and nine counts of wire fraud.
