The CHP has detained one possible suspect in the shooting and another may still be at large, Wilkenfeld said.

A witness who didn’t want to be identified saw the incident go down.  “And I looked out the window and saw one car spin around. The other car hit it and I saw two men jump out of the front seat of the car and run down the freeway.”
