Monroe Woman Charged With Poisoning Husband

MONROE – A township woman was charged Tuesday with the murder of her husband, who died after being poisoned, Middlesex County Prosecutor Bruce J. Kaplan and Monroe Township Police Chief John J. Kraivec announced.

Tianle Li, 40, was charged with the Jan. 26 death of Xiaoye Wang, a 39-year-old computer software engineer who lived with his wife on Stanley Drive.


Li was charged following an investigation by Sgt. Jason Grosser of the Monroe Township Police Department and Investigator Jeffrey Temple of the Middlesex County Prosecutor’s Office.

According to authorities, the investigation determined that Li and Wang, who were in the process of getting a divorce, had been involved in a series of domestic disturbances since April 2009.

Investigators determined that Li, who had been employed for 10 years as a chemist at Bristol-Myers Squibb, had obtained an undisclosed quantity of thallium, a highly-toxic metal, and allegedly administered a portion of the substance to her husband between December 2010 and January 2011.

After becoming ill with apparent flu-like symptoms, Wang checked himself into University Medical Center at Princeton on Jan. 14. A series of tests, completed on Jan. 25, determined that he had been poisoned with thallium.

Officials at the hospital immediately notified authorities, who began the investigation. Wang was pronounced dead at the hospital on Jan. 26 at 3:10 p.m.

The results of an autopsy performed by the Middlesex County Medical Examiner’s Office confirmed that Wang died from thallium poisoning and that his death was a homicide.

Kaplan thanked officials at the hospital and at Bristol-Myers Squibb for their quick response and cooperation during the extensive investigation.

The prosecutor also cited invaluable assistance from special agents at the FBI office in Newark, the FBI laboratories at Quantico, Va., the New Jersey State Police Hazardous Materials Unit and the Middlesex County Hazardous Materials Unit.

The hazardous materials specialists, who undertook an extensive investigation at Wang’s home, concluded that no one else was exposed to thallium

Li initially was arrested on Jan. 28 and was charged with a count of hindering her own apprehension for providing police with false statements during the investigation into Wang’s death. She is being held at the Middlesex County Adult Correction Center in North Brunswick. Her bail was set at $150,000 on the hindering charge. Superior Court Judge Bradley Ferencz today set bail at $4 million on the murder charge, bringing the total to $4.15 million.
