TRENTON, N.J. - Lisa Leitten is finished living her double life.
For the past three years, the soft-spoken, 30-year old moved from Missouri to Texas to Virginia, applying for jobs at businesses dealing with animals. She gave her real name, and some real details about herself: a master's degree in animal psychology and prior work at a primate sanctuary in Florida.
What she didn't reveal was that she was also working for an animal welfare organization, and that she wore a hidden camera to document instances in which animals were treated with what she calls horrific neglect and cruelty.
Leitten called her last assignment for People for the Ethical Treatment of Animals her most wrenching: nine months in a Virginia lab owned by Princeton, N.J.-based biomedical firm Covance Co. There, she says, monkeys were denied medical care and abused by technicians. The company denies the claims, says it treats the animals properly and has accused Leitten of illegally working under cover.
