N.J. woman sentenced to life in prison for fatally poisoning husband with thallium

By Sue Epstein - The Star-Ledger

September 30, 2013

NEW BRUNSWICK — A former chemist at Bristol-Myers Squibb was sentenced today to life in prison for murdering her husband by feeding him thallium, a tasteless, odorless and highly lethal chemical, after he sought a divorce.

Judge Michael Toto ordered Tianle Li of Monroe to spend life in state prison. Under the terms of the no early release act, Li, who is 44, must serve 85 percent of her sentence, or at least 62 years, six months and 19 days in prison.

A Middlesex County jury convicted Li in July of fatally poisoning her husband with thallium on multiple occasions.

"Ms. Li sat at her husband's bedside and watched his condition deteriorate knowing there was an antidote for the poison. This was a planned, calculated act performed in a depraved manner," the judge said.

Li cried as she thanked her mother who came from China to take care of the couple's now 4-year-old son and she insisted "I didn't murder Xiaoye Wang and I will appeal."

She said she believed "we have a solid case" to appeal.

Middlesex County Deputy First Assistant Prosecutor Christie L. Bevacqua said the woman devised a plan to maximize her husband's suffering.

"Rather than allow her husband to divorce her, Tianle Li chose murder," the prosecutor said. "She chose death and she didn't choose a simple, fast death. She chose one that put him through a lot of pain. While Li was outwardly at his bedside she was keeping a journal of his symptoms. She calculated everything — how to kill him and how to get away with his murder."

Bevacqua read a statement from Wang's father, who lives in China, about the impact his son's death has had on him and his family.

"I had to bury our son," Ming Wang said. "I'll never be able to see Xiaoye's bring smile. We will only live the rest of our lives mourning our loss."

Defense attorney Steve Altman told the judge he tries to "humanize" his client at sentencing and tried to "explain the circumstances why the person I represent is here in the courtroom."

Talking to the judge he said, "During the trial you learned the history of her life. Immigrants always need to assimilate. You saw the conflicts that exist coming from an Eastern culture and trying to get comfortable with Western culture. I think that's what brought us here today."

He said Li has been westernized but the fighting began when Wang's family came from China in 2009 after the birth of their son to help her with the child.

"Li was Westernized but her in-laws came from the Eastern culture and couldn't accept the Western culture. Poor Mr. Wang was caught in the middle of the situation. There was a mix of issues and facts and cultures that gradually deteriorated and brings us here."

Wang filed for divorce in 2010 and moved out of the house but his wife asked him to move back to help take care of their son.

Authorities charged that Li began poisoning her husband as early as November 2010, and continued to do so even as he lay in a hospital bed.

Wang checked himself into University Medical Center in Princeton, complaining of abdominal pain, on Jan. 14, 2011, the day the couple was supposed to finalize their divorce in a New Brunswick courtroom. He remained hospitalized until his death on Jan. 26, 2011, the day after doctors received test results showing he had lethal amounts of thallium, a heavy metal, in his system.

Wang’s parents have filed a lawsuit against the hospital and his widow’s former employer on behalf of their grandson. They insist the hospital failed to take Wang seriously when he suggested his wife had poisoned him, and that Squibb should not have granted Li access to thallium after a fellow employee had obtained a restraining order against her.

 
 

Jury convicts Monroe woman of poisoning her husband

By Sue Epstein - The Star-Ledger

July 09, 2013

NEW BRUNSWICK — Just as she had throughout her murder trial, Tianle Li sat stoically as the guilty verdict was read.

A Middlesex County jury today convicted the 44-year-old former chemist at Bristol-Myers Squibb of fatally poisoning her husband in January 2011 with thallium, a tasteless, odorless and highly lethal drug, after he had sought a divorce.

Li’s mother, who came to the United States from China to care for the couple’s 4-year-old son, sat behind her daughter in the courtroom. But she, too, betrayed no emotion, and mother and daughter did not exchange even a glance after the foreman delivered guilty verdicts on charges of murder and hindering her own prosecution.

Li, a Chinese citizen, faces life in prison. Superior Court Judge Michael Toto, who presided over the six-week trial in New Brunswick, set a sentencing date of Sept. 30.

The lack of emotion at the culmination of a six-month investigation and trial was in sharp contrast to the stormy relationship Li had with her husband and victim, Xiaoye Wang, 39. Testimony revealed that police had been called to the couple’s spacious Monroe home 16 times to intervene in domestic disputes, and Wang once told officers that his wife had poisoned him.

Outside the courtroom later, Li’s mother, who identified herself only as "Mrs. Li," fought back tears when asked, through an interpreter, for her reaction to the verdict.

"I know my daughter was innocent. Even when I was in Peking, I knew," she said, using the historical name of the Chinese capital, Beijing. "Her life is ruined now."

Li did not testify in her own defense. But her attorney, Steven Altman, told the jury there was no evidence that she poisoned her husband or ever gave him thallium.

Christie Bevacqua, the Middlesex County deputy first assistant prosecutor who tried the case, said of the verdict, "We believe justice was served."

Authorities charged that Li began poisoning her husband as early as November 2010, and continued to do so even as he lay in a hospital bed.

Wang checked himself into University Medical Center in Princeton, complaining of abdominal pain, on Jan. 14, 2011, the day the couple was supposed to finalize their divorce in a New Brunswick courtroom. He remained hospitalized until his death on Jan. 26, 2011, the day after doctors received test results showing he had lethal amounts of thallium, a heavy metal, in his system.

Wang’s parents have filed a lawsuit against the hospital and his widow’s former employer on behalf of their grandson. They insist the hospital failed to take Wang seriously when he suggested his wife had poisoned him, and that Squibb should not have granted Li access to thallium after a fellow employee had obtained a restraining order against her.

Leading up to today’s verdict, the jury spent more than two days listening to a replay of several witnesses’ testimony during the trial, which began in late May. Jurors were forced to begin deliberations all over again after one of them was excused for personal reasons and replaced by an alternate. In total, they took a little over three hours to convict Li.

An FBI toxicologist testified that thallium is often called "the perfect poison" because it is undetectable by most laboratories testing for heavy metals. The toxicologist, Cynthia Morris-Kukoski, also testified that the drug was difficult to obtain because it is banned from commercial use and not available to the public.

Other testimony revealed that Li had obtained four bottles of thallium in November 2010 at work, before returning three of them later that month and the following December.

Li tried unsuccessfully to go back to China, with her son and an aunt, just before her husband’s death, but was unable to pay for the tickets.

She was charged with obstruction on Jan. 28, two days after Wang died, after she told police that she had never worked with thallium, only to be contradicted by records investigators obtained from Squibb. She was charged with murder several days later.

 
 

Fate of Monroe woman charged with poisoning her husband rests with jury

By Sue Epstein - The Star-Ledger

July 02, 2013

NEW BRUNSWICK — The case of a Monroe Township woman charged with murder in the poisoning death of her husband more than two years ago has gone to the jury.

Tianle Li, 44, a research chemist at Bristol-Myers Squibb until her arrest two years ago, is charged with using thallium to murder Xiaoye Wang, 39. She is also accused of hindering her own apprehension by telling police she never had thallium or worked with the poisonous heavy metal. Prosecutors say Li killed Wang to avoid finalizing their divorce.

Jurors in New Brunswick deliberated for less than two hours today before going home. They will resume deliberations Wednesday morning.

“There is no proof that Tianle Li gave her husband thallium,” Li's attorney, Steven Altman, said in his closing argument. “There is no proof Tianle Li transported thallium in her car or into her home to give it to her husband. Tianle Li is not guilty.”

But Deputy First Assistant Middlesex County Prosecutor Christie Bevacqua called Li a “murderer,” and said “all of the evidence points at Tianle Li. There is no other person.”

Bevacqua laid out the evidence she presented during the trial, including Li’s ordering four bottles of thallium at work in November 2010, her efforts to purchase one-way tickets to China for her aunt, son and herself in the days before Wang died, and her visiting websites for criminal attorneys and the state judiciary system the day before his death.

“Her actions displayed a consciousness of guilty,” Bevacqua said, adding later that, “It was all about control. She wanted to control Xiaoye Wang. She is unhappy about getting divorced. She would lose status.”

The prosecutor said Li “purposely chose a rare poison,” for which doctors would not immediately test when Wang was admitted to the hospital on Jan. 14, 2011, the day the couple were supposed to finalize their divorce.

Thallium is tasteless, odorless and deadly in small amounts—“the perfect poison,” Bevacqua said.

“It was cold, it was cold-hearted and it was calculated,” Bevacqua said, noting that with Wang's death, Li “would have the house, hers and his finances and her son.”

But, Altman told the jury Li had no reason to kill her husband.

He said the custody of their son, financial arrangements and property settlement had been finished and they were going to sell the house, of which she was to make $250,000.

“The proof and evidence do not support divorce as a motive,” Altman said.

He told the jury Li “never made an attempt to leave the country” during Wang’s hospital stay, but Bevacqua displayed records that indicate she sought and obtained a passport and Chinese visa for her son, and made the reservations for the one-way trip to China.

“There was no accident here. She thought she was going to get away with murder,” the prosecutor said. “Unfortunately, for Xiaoye Wang, she did a good job.”

Wang died Jan. 26, 2011 and Li was arrested two days later.

 
 

FBI expert: Monroe man given fatal thallium dose before he was hospitalized

By Sue Epstein - The Star-Ledger

June 26, 2013

A Monroe man received a fatal dose of thallium only days before he was admitted to the hospital with abdominal pains, an FBI toxicologist told a jury today.

Cynthia Morris-Kukoski, testifying at the trial of Tianle Li, who is charged in the murder of her husband, Xiaoye Wang, 39, said she reviewed all of Wang’s medical records from his hospital stay, along with the Middlesex County Medical Examiner’s report and lab test results before concluding that Wang was given the poison the week of Jan. 9, 2011.

The state has argued that Li poisoned her husband after the estranged couple had a mediation session, in which they fought over distribution of their financial assets— the last step before their divorce— a divorce Li did not want—became final.

Li and Wang were scheduled to go to court to finalize the divorce on Jan. 14, 2011, but instead, Wang admitted himself to University Medical Center in Princeton with abdominal pains. He died Jan. 26, 2011, a day after tests for thallium in his system came back positive.

Li, 44, was a research chemist at Bristol Myers Squibb and obtained the thallium through work, according to testimony in the trial, now in its fifth week in Superior Court in New Brunswick.

Thallium is a highly toxic heavy metal that is tasteless, odorless and deadly in small amounts, according to Morris-Kukoski.

“It is referred to as the perfect poison,” she said. “It is odorless, colorless, tasteless and undetected by most labs. Hospitals need to send to an outside lab and specifically ask for a thallium test.”

Middlesex County Deputy First Assistant Prosecutor Christie Bevacqua asked Morris-Kukoski how much thallium it took to kill a person and asked her to compare it to a packet of “Sweet’N Low,” which she handed her.

“A lethal does is an average adult is about one gram,” Morris-Kukoski said. “It is less than this packet.”

The toxicologist said she does not believe Wang was given any of the poison while he lay in his hospital bed, only before he entered the hospital.

Christine Stefanelli, a former cellmate of Li’s at the Middlesex County jail, where Li has been held since her February 2011 arrest, testified last week that Li told her she gave her husband thallium three times, including one dose through his IV tubes in the hospital.

Li is charged with murder and hindering her own apprehension for telling authorities at first that she never ordered or used thallium at work. Investigators learned subsequently that she ordered four bottles of thallium from Bristol Myers Squib in the two months before her husband’s hospitalization.

The trial will resume before Superior Court Judge Michael Toto in the morning.

 
 

Level of poison in Monroe man's system was "off the charts," lab tech testifies

By Sue Epstein - The Star-Ledger

June 5, 2013

A laboratory technician for the Mayo Clinic in Minnesota testified today that a Monroe Township man had so much thallium in his system in January 2011 that “it was off the charts.”

Curtis Rykal was testifying on the first day of the murder trial of Tianle Li, who is charged with using thalium to poison her husband, Xiaoye “Alex” Wang, 39, who died Jan. 26, 2011 after 12 days in University Medical Center in Princeton. The case is being heard in Superior Court.

Rykal, who specializes in testing for heavy metals, said he ran a test on Wang’s urine for thallium on Jan. 24, 2011.

“The results were very positive,” he said during testimony in Superior Court in New Brunswick. “They were higher than our highest reportable amount. It was off the charts, I have never seen results that high.”

Thallium is a highly toxic heavy metal that is tasteless and odorless and is deadly in small amounts, according to officials.

Li, 44, was a research chemist at Bristol Myers Squib and obtained the thallium through work, authorities said.

Before Rykal testified, Middlesex County Deputy First Assistant Prosecutor Christie Bevacqua told the jury Li “is a murderer.”

“She packs a potent punch,” Bevacqua said. “Her weapon is her brain. She is a chemist with easy access to deadly weapons — many deadly weapons. Her weapon of choice was thallium, that perfect poison. It’s odorless, colorless and tasteless. It will kill in small amounts and is very hard to detect.”

The prosecutor said Li returned four used bottles of thallium to Bristol Myers Squib, “missing enough of the poison to kill multiple people.”

She said Li “also had an escape plan.”

Bevacqua said she had obtained a passport for her son and visas to China, along with one-way tickets to China booked for Jan. 25, 2011 for her aunt, her son and herself, but she did not make the flight.

Steven Altman, Li’s defense attorney, countered by commending Bevacqua on what he called “a wonderful speech, very theatrical,” but said, “that’s not why we’re here.”

He said it is for the jurors to decide if Li is a murderer, not the lawyers.

“There is no proof that (Tianle Li) poisoned her husband,” Altman said, noting she spent every day at her husband’s bedside, feeding him and praying for his recovery. “The key question here is, are (Tianle Li’s) conduct consistent with those of someone that wanted her husband dead?”

Wang left the Monroe Township home in the spring of 2010 and filed for divorce from Li in July 2010.

Michael Green, Wang’s divorce attorney, testified the couple eventually reached agreements on custody of their 2-year-old son and, on Jan. 10, 2011, agreed on how to split their finances and property, but not until they had a “very contentious,” and “loud” argument at the offices of the mediator trying to help them settle the economic issues.

With the agreements in place, the estranged couple had a court date on Jan. 14, 2011, to finalize the divorce, but never made it.

Green said Wang called him the morning of Jan. 14, 2011 to tell him his wife’s aunt became ill and Li was taking her to the hospital so they couldn’t go to court. By that evening, Wang joined the aunt at the Princeton hospital, where he was admitted with stomach pains and flu-like symptoms. He died Jan. 26, 2011.

 
 

Monroe Twp. woman pleads not guilty to fatally poisoning husband with thallium

By Sue Epstein - The Star-Ledger

May 17, 2013

A Monroe Township woman pleaded not guilty this morning at her arraignment on charges she murdered her estranged husband by poisoning him with thallium over a two month period ending with his death on Jan. 26.

Tianle Li, 40, told Superior Court Judge Michael Toto that she understood the charges contained in an indictment handed up against her — that she murdered Xiaoye (Alex) Wang, 39, and then hindered her own apprehension by telling police she had "nothing to do with thallium."

The grand jury charged in the indictment that Li began feeding the thallium, which is highly toxic, but odorless and tasteless, to Wang on Nov. 16, 2010, and continued until he died Jan. 26, 2011, at University Medical Center in Princeton.

Middlesex County Assistant Prosecutor Nicholas Sewitch has said Liu gave thallium to Wang in the hospital, where he admitted himself on Jan. 14, complaining of virus-like symptoms. It was not confirmed until Jan. 25, 2011 that he suffered from thallium poisoning.

Authorities said Li, a chemist at Bristol-Myers Squibb, got the poison from work.

The couple was living in the same house with their 2-year-old son, but were in the final stages of divorce.

The prosecutor said last month that Li applied for a rush visa for her son to take him to China, where she and her husband were born, and two days before Wang died she tried to buy plane tickets to China.

Li is in the Middlesex County jail on $4.15 million bail.

 
 

Prosecutor says Monroe woman continued to poison estranged husband at Princeton hospital

By Sue Epstein and Amy Ellis Nutt - The Star-Ledger

March 14, 2011

While Xiaoye Wang lay dying in a Princeton hospital in January, his estranged wife continued to feed him poison, a prosecutor said today.

And when her husband fell into a coma, Tianle Li, 40, tried to buy two one-way tickets — for herself and her 2-year-old son — back to her native China. Li, a scientist at Bristol-Myers Squibb, was charged last month with murdering Wang in the midst of divorce proceedings.

"She poisoned her husband to death," said Middlesex County Assistant Prosecutor Nicholas Sewitch at a hearing in New Brunswick.

Sewitch said Li obtained thallium, a highly toxic heavy metal that is tasteless and odorless, from the supply room at Bristol-Myers Squibb, although the research she was doing did not require it.

"She ordered (four) bottles of thallium," he said. "When she returned the bottles, over 90 percent of the thallium was gone."

Today’s hearing was scheduled after Li’s attorney, Steven Altman, filed motions to reduce her bail so his client could return to her home in Monroe and regain custody of her son, now in a foster home under the control of the state’s Division of Youth and Families.

In part, the hearing was a way for Altman to force the prosecutor to reveal evidence why Li’s bail should remain so high.

Superior Court Judge Michael Toto denied Altman’s motion, keeping bail at $4 million for the charge of murder and another $150,000 on a charge of hindering her own apprehension. A probable cause hearing was scheduled for April 26.

Li sat quietly, her hands cuffed in front of her, during the hearing, an expression of fear and pain on her face. Her mother, Jian Zhang, was in the courtroom, having traveled from her home in Beijing, China. She was accompanied by an attorney who spoke Chinese and translated for her and declined to comment after the proceedings.

Li began feeding her husband thallium sometime in December or January, according to Sewitch, which was before Wang, a computer engineer, admitted himself into University Medical Center in Princeton on Jan. 14, complaining of virus-like symptoms.

The prosecutor did not detail exactly how Li poisoned Wang, and said that when she was questioned by investigators, "she denied anything to do with thallium."

But during today’s hearing Sewitch told Toto that Li applied for a rush visa for her son in order to take him to China, and that two days before her husband died she tried to purchase airplane tickets.

On Jan. 28, just 48 hours after Wang’s death, authorities charged Li with hindering her own apprehension and jailed her. Two weeks later, she was charged with murder.

Li and Wang, who was 39 at the time of his death and also a native of China, were married in 2001 and were in the final stages of divorce, with the final hearing to dissolve their marriage scheduled for Jan. 14, but the hearing was postponed.

That day, Wang, a computer engineer in New York, took himself to the hospital. His condition deteriorated until he died Jan. 26, the day after doctors determined he was suffering from thallium poisoning.

The heavy metal can be bought over the internet, in powder or liquid form. Before it was banned for household use in this country almost 30 years ago, it was popular as a rodenticide and insecticide and is still used in the pharmaceutical industry, in glass and electronics manufacturing and medicinally in stress tests to help diagnose coronary artery disease.

Symptoms of thallium poisoning usually begin with gastrointestinal distress, followed by increasing nerve pain, hair loss, blindness and coma. There is only one antidote, Prussian blue, which is not readily available in the United States. Despite heroic efforts by the New Jersey Poison Control Center, state’s department of health and senior services, a sufficient dose of Prussian blue did not arrive until Wang was near death, and at that point, said doctors, nothing could more could be done to save him.

 
 

Before Monroe man's fatal poisoning, couple had history of domestic disputes

By Sue Epstein - The Star-Ledger

February 10, 2011

Xiaoye Wang’s marriage to Tianle Li saw bitter arguments that frequently brought police to the couple’s home in Monroe Township.

"There were a fair number of calls (to police)," Middlesex County Assistant Prosecutor Nicholas Sewitch said today. "More than five."

Things got so bad that Wang, 39, filed for divorce in July, citing irreconcilable differences. He also sought joint custody of the couple’s 2-year-old son, Isaac.

Li, 40, counter-sued a month later, citing the same reason and adding there was "no hope for reconciliation."

The couple’s 10-year marriage appeared to be over.

But on Jan. 14, the day a hearing would be held to finalize the divorce, Wang admitted himself to the University Medical Center in Princeton with "virus-like" symptoms. He died 12 days later from thallium poisoning, which authorities allege was administered by his wife.

Li remained at the Middlesex County jail in North Brunswick today in lieu of $4.15 million bail, charged with murder and hindering her own apprehension. Her attorney, Steven Altman, said his client denies having anything to do with her husband’s death.

Records indicate Wang moved out of the couple’s home on Stanley Drive home in Monroe sometime in June and into a Jersey City apartment.

Preceding the legal steps to end their marriage were calls to police, starting in April 2009 — about seven months after they had moved to Monroe.

Sewitch said none of the calls resulted in charges because there was never any sign of violence or injury to either Li or Wang. While Sewitch would not comment on the origin of the couple’s disputes, neighbors said they often heard them arguing and witnessed frequent visits by police officers.

Wang worked as a computer software engineer in New York City, while Li is a research chemist at the Lawrenceville offices of Bristol-Myers Squibb, the pharmaceutical giant.

After Wang admitted himself into the hospital, his condition progressively deteriorated until he died Jan. 26, the day after doctors finally determined he was suffering from thallium poisoning. After much searching, an antidote was found but by the time it arrived at the hospital, Wang was near death and nothing could be done to save him.

The divorce hearing, which was postponed due to his illness, had been rescheduled for today.

Thallium is a highly toxic heavy metal that is tasteless and odorless. It was once used in rat poison and insecticides, but was banned for that use in the United States and other counties in the 1980s. It is still used in glass and electronics manufacturing and medicinally in stress tests to help diagnose coronary artery disease.

Sewitch has not said how the thallium was administered, nor whether it was given in several small doses over time or in one dose. All he would confirm was that it was ingested in December or January. He also would not comment on where Li allegedly obtained the thallium, though he did say it would have been available to her at Bristol-Myers, where she’s worked since 2001.

 
 

Monroe woman is charged with fatally poisoning husband

By Sue Epstein - The Star-Ledger

February 8, 2011

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.
