Recently in two cases in China charges were dropped against convicts after new facts, or rather people, were discovered.

In the first case, 'Butchered' China waitress turns up alive:

The children of a Chinese butcher executed for murdering a waitress have appealed against his conviction after the "victim" turned up alive, the second such judicial blunder to be made public in recent weeks. Shi Xiaorong was 18 when she disappeared in 1987 at the same time as six pieces of a woman's body, sliced off "in a professional manner", were found in a river in southern Hunan province, a newspaper said on Thursday. Police arrested Teng Xingshan because he was a butcher by trade and because of rumours he used to go to the hotel where Shi worked to find prostitutes, the Beijing News said. Waitress Shi was later found to be serving a prison sentence with her husband for selling drugs, the newspaper said.

In the second case: She Xianglin was freed after serving 11 years of a 15-year jail sentence in central Hubei province for murdering his wife when she turned up not alive and with another man.

She Xianglin has said to have confessed under duress and torture. Yet the man now seems to bear no ill will. What can you do in these situations?

This week, as reported in Vietnam's Thanh Nien News, Mekong province apologizes to wrongly convicted ex-director. "The Bac Lieu People’s Court on June 16 gave an official public apology to the ex-director of the Mekong Delta province’s finance department for wrongfully convicting her of fraud in January 2005."

Fortunately for her, it only took 6 months and she's still alive.
