Donald G. Turnbaugh, special agent in charge of the U.S. Customs Service in Baltimore, shows photographs and a sample of thiodiglycol, an industrial lubricant that produces lethal mustard gas when combined with hydrochloric acid. Nicholas J. Defino, 64, of New Jersey and Dutch citizen Frans Van Amraat were charged in criminal complaints unsealed Monday with three counts of diverting shipments of the lubricant to Jordan for use as a chemical weapon by Iraq. Defino surrendered to Customs agents Monday, and Van Amraat was arrested in Milan, Italy, Jan. 26. U.S. authorities also said the manufacturer, Alcolac International Inc., had agreed to plead guilty to one count of violating export laws. Alcolac officials said the chemicals were sent to the Middle East without their knowledge.
