HOHHOT -- Serial killer and rapist Zhao Zhihong will appeal his death sentence in Inner Mongolia Autonomous Region's high court on Tuesday, the court announced on Saturday.

Zhao was convicted in February of crimes including the murder of 10 women.

The court declined a public hearing based on a need for privacy.

Zhao was apprehended in 2005 and confessed to a string of rape and murder cases, including one in Hohhot in 1996 that was pinned on 18-year-old Huugjilt. Huugjilt was exonerated in December 2014, 18 years after his execution.
