At 3:50 AM on November 5, the power supply in Li Laishun's home on Maliang Town Street in Qian County was cut off by someone. Soon after, sounds of fighting were heard from inside the house. A neighbor sleeping next door heard the sound of tiles on the roof and quickly got up to check, but found no abnormalities. Not long after, Kang Qin's father and brother-in-law knocked on the door, saying that there might be trouble at their in-laws' house, and then jumped over the wall into Li Laishun's home.
Upon entering Li Laishun's home, Kang Qin's father and brother were shocked by what they saw - blood covered the entire house. Their in-laws Li Laishun, his wife Zhou Hualin, and son-in-law Li Nan had already been killed. Their daughter lay in a pool of blood with serious injuries, and their one-year-old granddaughter had also been slashed.
