As the headlines from China focus on Michael Phelps and Nastia Liukin, other stories have gone largely uncovered such as the disappearance of a human rights advocate and her baby daughter.

Beijing-based human rights activist Zeng Jinyan and her baby daughter have been missing since August 7th. Zeng has been under house arrest for months. Her husband, prominent activist Hu Jia, was sentenced to a three and a half year prison term in April on charges of inciting subversion for criticizing Chinese government policies. Hu had advocated for AIDS victims and called for political improvements in China to accompany the Olympic Games.

Zeng has been out of contact with her family, friends and lawyer since a day or two before the opening ceremony, her lawyer Li Fangping told ABC News. He believes that public security officers have taken her out of the city until the end of the Games.

"The information we have received is that she has been taken out of Beijing," said Li. "It is part of Olympics security."
