Does anyone know:
Who he is?
Or where he was at the time of the assassination (ie. location on Zapruder film)?
Or what image is this called?

Could it have been John Chism? He was with his wife and 3 year old son in front of the Stemmons freeway sign at the time of the shooting as captured by the Bronson photo:

John Chisms police affadavit says the following:
At this point, I looked behind me, to see whether it was a fireworks display or something. And then I saw a lot of people running for cover, behind the embankment there back up on the grass. And at this point, I turned back around and saw the motorcade beginning to speed up, and everybody was laying down but the driver, of course. I didn't notice where it went. My wife and I began seeking cover, and we went to our car, and then we told the policeman about what we knew.
John Chisms wife said the following:
After the motorcade went by, after that, I jumped up and headed for my car, we were parked up on the freeway. A police patrolman came up where we were, and we told him what we saw.
