At 3:45 PM on January 1, 2008, a hospital in Haidian District, Beijing received an emergency call for medical assistance. After confirming the address, the hospital's medical staff quickly boarded the ambulance and headed to the scene.
On the ambulance, Zhou, the person in charge of this rescue mission, encountered an issue while verifying the emergency information: According to Cheng, who made the emergency call, the patient (female) is his wife. She is usually in good health with no significant past medical history. She had fainted after being struck on the head by some blunt object. However, when describing the injuring object and the cause of the incident, Cheng was evasive and vague, raising suspicions. For safety reasons, Zhou contacted the police station near Cheng's residence to conduct a joint rescue operation.
