XI'AN -- Yao Jiaxin, a university student who stabbed a young mother to death to cover up a hit-and-run accident, was executed on Tuesday in Xi'an, the capital of northwest China's Shaanxi Province, with the approval of the Supreme People's Court.

Yao, 21, a student at the Xi'an Conservatory of Music, was convicted of murdering Zhang Miao last October in Xi'an to prevent her from reporting an earlier incident in which Yao hit her with his car.

Yao was sentenced to death by the Xi'an Intermediate People's Court on April 22. He appealed his sentence after the trial.

The Shaanxi Provincial People's Procuratorate held that the facts of the case were clear and suggested rejecting the appeal and maintaining the court's judgment.

The Shaanxi Provincial Higher People's Court heard the case and rejected the appeal on May 20, sending the case to the Supreme People's Court for review.

The Supreme People's Court reviewed the case and held that Yao had committed the crime of intentional killing, based on the fact that Yao ran into the victim while driving his car and resorted to murder to silence her.

"Yao stabbed the victim's chest, stomach and back several times until she died. The motive was extremely despicable, the measures extremely cruel and the consequences extremely serious," said a statement provided by the Supreme People's Court.
