> Authorities say Matthew Unglesbee, 36, of Quincy, admitted mailing letters with white granules to four unidentified members of Congress. He said the substance was salt and that he meant it as a joke, though he knew recipients could view it as a threat. Preliminary tests found no biological or chemical toxins. He faces federal hoax and threatening-communications charges.
