IRVINE, Calif., Jan. 5 (UPI) — A third envelope containing white powder has been found on the University of California, Irvine, campus, officials said Tuesday.
The envelope, identical to two other letters with the words “black death” written on them, was sent to a woman who works in the computer sciences building, the Los Angeles Times reported. University security evacuated the Office of Information Technology on the third floor and shut down an elevator and the building’s ventilation systems.
The two white powder envelopes received Monday by an engineering professor and a sociology professor tested negative for toxic material, and no university workers reported any unexplained health problems, the newspaper said.
Orange County public health workers and paramedics checked people who were in the areas where the earlier envelopes were opened and FBI investigators were trying to identify the powder.
