AsiaNews, a Vatican-based news service, said Joseph Shulai Zhang and Sister Mary Wei Yanhui were apparently stabbed to death at the nursing home where they worked in the city of Wuhai in Inner Mongolia.
After the two failed to appear at morning mass, their bodies were discovered in a pool of blood in the home, which was housed within the local church, the report said.
The priest was apparently stabbed seven times, while the nun suffered one stab wound to the chest.
"This is a criminal matter, we are in the process of cracking this case," a city policeman, also surnamed Zhang, told AFP.
