WASHINGTON -- Bruce E. Ivins, the chief suspect in the 2001 anthrax attacks, was a 'sociopathic, homicidal killer' who planned to kill his co-workers 'because he was about to be indicted on capital murder charges,' a Maryland court was warned shortly before Ivins committed suicide last week.

Jean Carol Duley, a psychotherapist who had treated Ivins for six months, told the court July 24 that the microbiologist had purchased a bulletproof vest and gun and boasted of roaming the streets hoping to stab someone.
