I was walking my dog west on Foster past Kimball and only heard the crash (didn't see it) at Foster/Kimball because it was behind me. There were quite a few people at the intersection, so I'm hoping someone can attest to the events and got the license plate number. I only saw the car drive away.. it was a tan 2000's Cadillac with skinny rear tail lights. If the rider needs someone to verify the car, etc. please contact me.
