I had known about the letter from Malaysia in the anthrax case, recounted very well here and about Stephen Hatfill. What I hadn't known was this titbit:
His girlfriend was Malaysian-born—and a hoax package had been sent from Malaysia to a Microsoft office in Nevada.
The article does not explain how the subsequent suspect Bruce Edward Ivins managed to mail a package from Malaysia though I suspect these kinds of things are easily done.
The article was enjoyable though it was hard not to see why the FBI considered Hatfill a suspect (unless he was being set-up - I may be watching too much TV). In the end, this is a tale of how we can all buckle when the weight of one organization (not just the government) comes down on us.
