I don't think it likely these people were working for terrorists. They lived in california or massachusetts or london or moscow or israel. the terrorists must develop their weapons in places like afghanistan or iraq. the only commonality is that they were experts in this field. As the author pointed out, the odds of this happening without someone making it happen are so small as to be a non-factor. The story about the chinese researcher killing the russian researcher in california is especially chilling.

Maybe they're dead because they refused to work for terrorists.
