Burden of proof

It was this case that prompted the passionate prosecutor to gain computer expertise so she would be better equipped to deal with online crimes, which she realized would increase as the Internet was becoming more and more popular in China.

Now, Wang handles about 60 cases a year, which means she at least has one new case to deal with every week. Her biggest anxiety: a murder case.

In 2007, Wang was asked to interrogate a man in his 30s, who was accused of killing a woman in an apartment in Beijing.

"The man went back on what he had said several times during the inquiry, but the evidence wasn't solid enough," she says.

However, considering all the evidence against him, such as video from a surveillance camera putting him at the scene around the time the murder took place, she decided to approve his detention and open the door to his prosecution.

"To ensure I handle each case accurately, especially the murder ones, I keep track of them, even though the next steps are not my responsibility," she says.

She always smiles at everyone, although she feels the weight of responsibility, says Han Wanyan, another prosecutor in the authority.

"No matter how busy my work is, I take time to accompany my daughter and find time to read some good books, which helps me find inner peace," Wang says.

"I heard my 13-year-old child say: 'I have evidence to refute you'," she adds, laughing.
