(CBS/AP) NEW BRUNSWICK, N.J. - Tianle Li, a chemist from New Jersey, was sentenced to life in prison Monday for fatally poisoning her husband during a contentious divorce.
Li won't be eligible for parole for nearly 63 years.
She denies killing her husband and is appealing her July conviction.
The Monroe resident worked for New York City-based biopharmaceutical company Bristol-Myers Squibb. Prosecutors alleged she poisoned husband Xiaoye Wang, a computer software engineer, by giving him thallium, a tasteless, odorless poison, which she ordered through work in 2010.
Thallium is banned for consumer use in the United States. It can be fatal in tiny doses and is difficult to detect in lab tests.
Wang died in January 2011.
Judge Michael Toto says Wang's murder was "planned, calculated and committed in a cool and depraved manner."
