That's it, just the question?
Back a couple of years ago, there were quite a number -- a dozen or so --- scientists, who died under somewhat mysterious circumstances during a short period of time, and they all just happened to be researching dontageous diseases suitable for bioterror. It was becoming a little hard to believe that all of them were just coincidences, but I haven't heard or read about it any further since then.
Sounds like each of them made a viable discovery, then didn't live long enough to document it.
