On Friday, a similar review of a 1994 rape and murder case that took place in north China's Hebei Province began in east China's Shandong Province. The off-site review was aimed at clearing doubts about the trial for Nie Shubin, who was convicted and executed for the crime in 1995 at the age of 21.

Like Huugjilt's case, another man, Wang Shujin, apprehended by police in 2005, confessed to the rape and murder in Hebei's capital of Shijiazhuang.

Since 2005, Nie's mother, Zhang Huanzhi, already in her 70s, visited Hebei Provincial Higher People's Court countless times, demanding a review of the case in order to prove the innocence of her son.

Shang Aiyun, Huugjilt's mother, said she has been keeping in touch with Zhang, encouraging the grieved mother to be strong to continue the fight for her son's justice.
