Around noon, a young woman and a man came out of a building. The man dressed in black headed directly toward them and pulled a knife out of his pocket. Recognizing the menacing face, the woman started screaming and ran to a nearby grocery store. While she pleaded with a shop worker for help, the man in black had already killed her companion.
Liu was the first person to arrive on the scene, quickly followed by other security guards. The victim was lying on the ground covered in blood, while the murderer was attempting to pry open the shutters that the grocery store had rolled down to protect the woman. Liu was terrified and could only recall calling the police and an ambulance. The murderer was caught later that day at a railway station.
