More than 100,000 Chinese have signed a petition on a White House website urging the US to deport the chief suspect in a 19-year-old case of poisoning. 
  
 Chinese citizens dubious about their country’s legal system are seeking justice in an unusual place for the victim of an alleged attempted murder in China. They are taking the case to the White House. 
  
 More than 100,000 people have signed a petition on a White House website urging the US to deport the chief suspect in a 19-year-old unsolved case of poisoning that continues to excite strong emotions here. Adding piquancy to the case: The suspect is very well-connected politically in China. 
  
 In 1994, a chemistry student at one of China’s top universities, Tsinghua, called Zhu Ling was poisoned with Thallium, a chemical often used in rat poison. She did not die, but was left nearly blind, paralyzed, and brain-damaged, needing constant care from her increasingly aged parents. 
  
 Her fate has not been forgotten, says Wu Hongfei, a former journalist who has followed Ms. Zhu’s case closely, partly because she was pretty and smart and partly because Tsinghua is so prestigious. But the main reason, says Ms. Wu, is that the only real suspect in the case “had close ties to high ranking officials.” 
  
 Sun Wei, Zhu’s roommate at Tsinghua, was investigated by the police at the time of the incident, but was never charged, though reports at the time said she had access to Thallium. The police said there was not enough evidence to pursue the case; many ordinary citizens believe that evidence was covered up because Ms. Sun’s father's cousin had been deputy mayor of Beijing and her grandfather was reputedly a friend of then President Jiang Zemin. 
  
 “Because of her family background … she avoided punishment,” complained one netizen, posting as “@Jinse Guniang” on Sina Weibo, a Twitter-like social media platform. 
  
 Sun changed her name and is believed to now be living in the United States. 
  
 The case has erupted again into the public consciousness in the wake of last month’s arrest of a student for fatally poisoning his roommate at another prestigious university, Fudan, in Shanghai. The suspect in that case has confessed to putting poison in his dorm-mate’s water dispenser, saying he did it for a joke. 
  
 Zhu's case continues to rankle. On Monday, after just three days on the White House website, the petition concerning Sun had drawn more than the 100,000 signatures required for the US administration to offer a response. On Sina Weibo, terms relating to the case accounted for three of the top five search words. 
  
 Journalist Wu has little hope that the White House petition will do any good. Dissident artist Ai Weiwei “attracted a lot of international attention but he is still not allowed to leave China,” she points out. But as public pressure mounts at home, the authorities appear to be listening. Over the weekend, social media posts including such words as “Thallium” or “Zhu Ling” were being scrubbed from the Internet by Chinese censors, apparently afraid of criticism of the Chinese judicial system. 
  
 By Monday, the censors had lifted their search blocks. And even the state owned media have joined in the chorus of demands. 
  
 The online version of Peoples’ Daily, organ of the ruling Communist Party and Xinhua, the official news agency, shared a headline: “China, Ruled by Law, Should Seek Justice.” At long last, the victim of that unsolved poisoning seems to have friends in high places, too. ||||| Bei, who later went on to start a software development company, for the first time realized that the Internet was going to be a game-changer. “Before that you could not imagine there are nearly, I think, 200 doctors all over the world who can join together to diagnose this girl, and make the right diagnosis, and give treatment advice. It’s impossible to imagine, it’s like a dream,” he told me. 
  
 Unfortunately, this story has far from a happy ending. Over the years there has been intense netizen speculation that Sun Wei, Zhu’s roommate, was saved from prosecution by her family connections. Sun Wei was reportedly the only person in Zhu's circle with access to thallium. (Sun Wei denies this.) One theory is that she was motivated by jealousy. Online bulletin board sites were flooded with rumors, accusations of guilt and attempts to even hunt down Sun Wei. 
  
 We may never know what really happened. But as a satisfying verdict was never reached in Chinese courts, someone appearing to be Sun Wei ended up testifying in the court of online opinion. The pressure grew so fierce that in 2005, Sun Wei issued a statement on the popular Tianya bulletin board site. “I am innocent,” she wrote. “I am also a victim of the Zhu Ling case.” She claimed that she had been questioned by police and subsequently cleared of suspicion. Sun Wei even went as far as to scold Chinese netizens for their behavior: “On the Internet, even though everyone is just a virtual ID, one should still be rational and objective, and responsible for his own words and actions.” 
  
 Netizens, of course, were far from convinced. Now many believe that Sun Wei has left China, and is residing in the United States. There is even a petition on the White House Web site demanding the deportation of Sun Wei. It already has thousands of signatures. And now, making matters worse, netizens suspect that weibo is covering something up. As of May 4, when you searched for Zhu Ling’s name on Sina weibo you learn that according to Chinese law, the results cannot be displayed. Even “thallium” has become a sensitive word, as are other words connected to the case. 
  
 This level of Zhu Ling-related censorship is new. Zhu Ling’s story has been floating around the Internet for years, and has even been covered by Chinese state media. But now censors are getting worried, in large part because at the end of the day, people are not simply angry about one unsolved crime. Rather, anger over this case reflects a widespread lack of trust in China’s rule of law. As long as the truth of Zhu Ling’s case hasn’t come to light and nobody has been brought to justice, one netizen wrote, “the Chinese dream can only be the powerful officials’ dream.” 
  
 Weibo censorship has only made people more angry and suspicious. One netizen wrote, “A lot of information about Zhu Ling has been censored. So we can then see that Sun Wei is the murderer.” Another said, “You can delete Weibo and the two characters for Zhu Ling. Can you [also] delete the truth?” One person encouraged microbloggers to continue inundating weibo with comments related to the crime. That way, short of Sina shutting down weibo itself, it would be impossible to erase the people’s pursuit of justice. 
  
 Of course, it would be far better if this pursuit took place through the actual legal system, rather than on the Internet. The silver lining is that intense interest on weibo is yet another sign of increasing rights awareness among ordinary Chinese, as well as a collective desire for a fairer system. From the beginning of the Zhu Ling drama, the Internet has helped ordinary citizens form networks to solve problems. It helped to save Zhu Ling’s life, and now it is ensuring that her case is not forgotten. Nor is this online activism in pursuit of an abstract notion of justice. If we don’t stand up for Zhu Ling, people reason, who will stand up for me? 
  
 That's why so many people remain fascinated by Zhu Ling's case. Bei Zhicheng puts it best: “Many of our generation have successful careers and comfortable lives,” he said. "Zhu Ling should have been one of us.”

A:
An unsolved poisoning case has enthralled China, 19 years after the fact, and now more than 112,000 people have signed a petition asking the White House to investigate and deport a former suspect who is said to have moved to the US. Zhu Ling was a chemistry student at a top Chinese university when she was poisoned with Thallium in 1994, the Christian Science Monitor explains. She survived, but is now almost blind, paralyzed, and suffering from brain damage. Her case attracted quite a bit of attention at the time owing to the fact that she was young, smart, and attractive; it was never solved, and now a recent, similar poisoning has re-ignited interest. Police investigated Zhu's roommate, Sun Wei, who was said to have access to Thallium, but she was never charged due to a lack of evidence. Many speculated, however, that evidence was actually covered up because Sun's family was politically connected. She changed her name and is thought to live in the US now; in 2005, she even issued a statement declaring her innocence, the New Republic adds. The case was brought back to the forefront of public attention last month, when a student was arrested for fatally poisoning his university roommate. A journalist who has followed the case doubts the petition will do any good, but the Chinese government has definitely taken notice: Censors were briefly removing social media posts about the case, but now even state media are calling for further investigation.
