Mr. President Obama,
19 yeas ago, Zhu Ling, then at Tsinghua University, was allegedly thallium poisoned by a mere suspect Sun Wei. The case was secretly shelved because of the Sun's family having powerful political connections with Chinese government. We, international volunteers from China, America and many other countries, share a common request: reopen the Zhu Ling case and bring judicial justice for Zhu Ling.
According to the White House said in a statement, "President Obama and President Xi will hold in-depth discussions on a wide range of bilateral, regional and global issues," when you meet with Chinese President Xi on June 7-8 in CA, we urge you to talk our common request with President Xi.
Thank you.
