Silvya Oommachen, a former lab worker, has been arrested and charged with taking and destroying 42 cassettes, each holding 96 protein crystal samples, from three cryogenic containers at the Stanford University Synchrotron Radiation Lightsource, a federal facility managed by the university, The Palo Alto Daily News reported. The research objects cost about $500,000 to produce, the newspaper said. Oommachen has not entered a plea in the case. But a Federal Bureau of Investigation statement said she admitted to the acts, and blamed a "very bad relationship with her supervisor," giving her the belief that she could "reverse some of the bad karma she was experiencing" by destroying the samples.
