At around 9:20 PM on August 4, 2009, in front of the Zhejiang Broadcast Group on Moganshan Road, a shrill screech of brakes tore through the night sky. Under the collision of a Porsche Cayenne, Ma Fangfang, a 17-year-old girl, screamed in agony, her body flying over 20 meters, blood splashing on the zebra crossing. The offending vehicle was a black Porsche Cayenne with the license plate number Zhe A892E9.
