UPDATE 3:13PM EST: The driver of the motorcycle is in fact alive, see pic below.
Translated from Chinese via Google Translate:
“On February 15, 2020, several Chinese international students drove a sports car in the mountains north of Los Angeles (Azusa Highway 39). They rushed to the opposite road when cornering and hit a motorcyclist! Then I asked for help in the WeChat group and wanted a lawyer to justify his crime! It is really angry! Fortunately, Gopro on the motorcycle rider’s helmet made the accident clear. May the dead rest in peace, and may the murderer be punished by law!”
