The BMW, which carried three passengers, had crashed with a 2012 Nissan sedan driven by Johnson Chao, 46, of Redwood City. Investigators do not yet know what caused the drivers to lose control of their cars and collide, CHP spokesman Officer Art Monteil said. Both vehicles came to rest within the center median.
The driver's side of the BMW struck a tree. The force of the collision split the car in half, and Thomas was thrown from the vehicle. Two passengers, a San Carlos man, 21, and a 21-year-old Sacramento woman, received minor injuries. A third passenger, a San Francisco woman, 19, had moderate injuries, Monteil said.
Chao's Nissan overturned and came to rest on its roof. It was partially on top of the concrete center median. He was able to extricate himself. Chao and the BMW's passengers were transported to Stanford Hospital.
The collision is currently under investigation. It is unknown at this time if alcohol or drugs were a factor, Monteil said. Any witnesses to this collision are asked to contact Officer William Parker at 650-369-6261.
