Federal authorities said they have arrested a former employee of a national laboratory who is suspected of slipping past security guards and destroying a research project.

Silvya Oommachen, 32, of Palo Alto was charged Monday with destroying government property. Investigators say she removed more than 4,000 cryogenically frozen crystal protein samples from cold storage on July 18. The samples thawed over that weekend and were ruined.
