I'm sorry, I realise I couldn't have been more mistaken, you are correct, I assumed the shot came from the broken window in the chamber. Another image just found on Bing archives, shows the man with the receeding hairline has both gold cufflinks and is wearing a black and white bracelet. It seems that we are looking at just one, same man.
No problem. This whole fiasco is confusing. I’m not sure anyone can really make things out properly.
