KINSTON, N.C. (Feb. 3)—A fourth person has died following a Jan. 26 explosion at a West Pharmaceutical Services Inc. facility, according to a Cox News Service report. Kevin Cruiess, 22, of Kinston, died from burns he sustained in the fire that damaged the firm's manufacturing plant. Faye Wilkins, 50, William Gray, 51, and James Byrd, 60, died in the explosion or shortly after, the news report said, and nine other workers are in critical condition, with two in even more severe condition. Investigators from the Federal Bureau of Alcohol, Tobacco, Firearms and Explosives and the State Bureau of Investigation continue to interview more than 200 of the 255 workers employed by West. The U.S Chemical Security Board said Jan. 30 that ignitable rubber dust, a by-product of the rubber molding process, combined with static electricity, is a possible cause of blast. West President and CEO Don Morel and company officials said the chemicals stored inside of the Kinston facility could not have created the magnitude of the Jan. 26 explosion.
