Plague Infected Mice missing from New Jersey Lab
Sept. 15, 2005 — The FBI and Centers for Disease Control and Prevention are investigating the disappearance from a New Jersey research lab of at least three mice carrying a deadly strain of plague.
The rodents have been missing for two weeks.
Sources say FBI agents and bioterrorism experts are interviewing and polygraphing employees at the University of Medicine and Dentistry in Newark, N.J., the location of the lab run by the Public Health Research Institute, a leading center for research on infectious diseases.
There are no indications of terrorism.
