Glad to hear I'm not alone in thinking that the guy on the right looks like John Doe #2. John Doe #2 is supposed to have looked like a Cuban (or Native American) to one eyewitness, and this guy looks like an angry Ricky Ricardo.
Also, this article says, agents have looked into a tip that Mr. Azmath may have been seen in 1993, around the time of the van-bombing of the World Trade Center, in an apartment with a man who was later convicted in the assault.
That sounds similar to John Doe #2, who was seen in connection with the OKC truck bombing.
