Reginald Denny survived. I saw him at the Santa Clarita Mall a couple of years after the riots. His head was dented and he had quipped on TV, that his daughter called him ‘Reginald Denty’. I don’t know if he is still living.
The website I saw said he had almost a 100 fractures in his skull - I assumed he had died. While some of this seems like it can’t be that long ago - I guess it has been quite awhile.
