When Xiaoye Wang checked into a Princeton hospital
last month, his case appeared to be routine. The computer engineer
from Monroe Township complained only of flu-like symptoms, authorities
say.
But for nearly two weeks, Wang struggled to get
better. On Jan. 25, after a series of tests, doctors discovered the
reason: Wang had been poisoned with thallium, a highly toxic metal.
He died in his hospital bed the following day. And
today, following an investigation that brought in the FBI and the
State Police, authorities charged Wang’s wife, Tianle Li, with his
murder.
A research chemist at Bristol-Myers Squibb since
2001, Li obtained an undisclosed amount of the radioactive substance,
authorities say, and administered a dose to Wang in December or
January.
Natives of China, Wang and Li moved to a new home
on Stanley Drive in 2008 and had a son. But a year later, the marriage
had soured, police say.
"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," Bruce Kaplan, the
Middlesex County prosecutor, said in a press release.
Li’s attorney, Steve Altman, said his client is
innocent.
"The divorce proceeding had been resolved in
principle by a property settlement agreement," Altman said. "Mr. Wang
was paying for support of his son. There was no motive for my client
to kill her husband."
He said Li, who goes by the name Heidi, has no
relatives in the United States. Their child, now 2, is in foster care,
Altman said.
Li, 40, was first charged with hindering her own
apprehension for giving false statements on Jan. 28, two days after
her husband died in University Medical Center in Princeton, Kaplan
said. The murder charge was lodged after an autopsy confirmed Wang was
poisoned with thallium.
After searching the couple’s home in the southern
end of Middlesex County, investigators concluded no one else had been
exposed to the metal. Thallium, a radioactive substance, is used
mostly in the electronics industry. It is also deployed in stress
tests to diagnose heart disease.
For poisoning purposes, it would be in a powdery or
crystallized state. The poison works by knocking out the body’s supply
of potassium and attacking the nervous system, the stomach and the
kidneys. Its effects can take weeks to kick in.
Li is being held in the Middlesex County Jail. Her
bail was set at $150,000 on the hindering charge, but raised another
$4 million after she was charged with murder.
Fred Egenolf, a spokesman for Bristol Myers Squibb,
said the company would have no comment about Li.
