Three people linked to white supremacist and anti-government groups are in custody. At least one weapon of mass destruction - a sodium cyanide bomb capable of delivering a deadly gas cloud - has been seized in the Tyler area.
Investigators have seized at least 100 other bombs, bomb components, machine guns, 500,000 rounds of ammunition and chemical agents. But the government also found some chilling personal documents indicating that unknown co-conspirators may still be free to carry out what appeared to be an advanced plot. And, authorities familiar with the case say more potentially deadly cyanide bombs may be in circulation.
