Fang Sihua, a farmer in Yueyang County, allegedly set fire to the house of his girlfriend, surnamed Li, in the county's Yanglin Township and used an axe to kill five people, including Li's parents and aunt.

A local government official in Yanglin Township said that Fang decided to take revenge on Li after he discovered that Li was considering remarrying her ex-husband.

Policemen of Yueyang County rushed to the site after the murder and apprehended Fang.
