Even if he really did kill himself, there is some very shady business going on here...

Bruce Ivins, scientist set for prosecution in US anthrax attacks, commits suicide
Bruce Ivins, a government scientist whom federal agents were preparing to prosecute in connection with the anthrax attacks that killed five in 2001, apparently committed suicide on Tuesday after learning authorities had identified him.
The death in Maryland of Ivins, who helped the FBI analyse anthrax samples used in the attacks, may bring to a close a long-running mystery in the US "war on terror". Following the September 11, 2001, terrorist attacks, the anthrax assaults crippled the US mail system and sowed fears the US was under attack from al-Qaida terrorists who had acquired biological weapons.
Ivins, whose name had not surfaced publicly in connection to the attacks, was a civilian bio-defence researcher at a top military research laboratory at Fort Detrick, Maryland. The 62-year-old scientist had worked at the lab for the past 18 years.
According to the Los Angeles Times, which first reported the death, Ivins had recently been informed of his impending prosecution. He died Tuesday in a Maryland hospital after ingesting a large dose of prescription Tylenol with codeine, a friend told the Los Angeles Times.
