The FBI has not said how much money was wired to the caller from the Hutchinson store on Tuesday, but police in Newport said workers at a Wal-Mart were so frightened by a bomb threat on Tuesday that they wired $10,000 to the caller.

Large grocery and discount stores as well as banks in roughly a dozen states have received calls from an unidentified man who is able to provide such specific details that employees believe he is inside or somehow watching them.

On Thursday evening, the FBI provided an updated list of stores and banks believed to be traceable to the same suspect or group of suspects. The bureau is also investigating whether other reported threats are connected.

The FBI list includes: a credit union in Albuquerque, N.M.; a Safeway store in Sandy, Ore.,; a grocery store in Buchanan, Mich.; Wal-Marts in Newport, R.I., and Rio Grande City, Texas; bank branches at Wal-Marts in Salem, Va., and Fairlawn, Va.; a Macey's grocery store in Orem, Utah; a Dillons grocery store in Hutchinson, Kan., a bank branch in Milford, Conn.; a Vons in Vista, Calif., near San Diego; a bank in Savannah, Mo.; a bank in Ithaca, N.Y.; and banks in Tampa and Wesley Chapel, Fla.

Authorities in Buchanan, Mich., had earlier said workers at a Harding's Market sent $3,000 to an account in Portugal. But on Thursday, Police Chief William Marx said flustered store employees made a mistake and the money was sent to Paraguay rather than Portugal, as the caller had demanded.

"They got their p's messed up," Marx said.
