I have been trying to find out the latest news on the investigation into the US anthrax scare of last year.
A web search was unproductive, including searches of media sites.
The latest I heard was that the perpetrator was suspected to be a government official http://old.smh.com.au/news/0203/20/world/world9.html , but this is 8 months old.
Has there been any breakthroughs that have not been reported, or have the investigators hit a brick wall?
