Only two hours after the blazing inferno on the roof of the Four Continents Hotel was put out, the police officers completed the investigation on all the survivors. While the fire burned, the Four Continents Hotel was surrounded by police officers. There was no second exit, so by subtracting the survivors from the people who entered the hotel, the police would get the number of fire casualties.
In the end, the authorities determined that the four special operations team members and the four emergency response team members, Zhang Heng included, were killed in the fire. Other than that, all residents on the twelfth floor had been killed, and some on the thirteenth and fourteenth floors.
