Now, the man the FBI named as the culprit, a biodefense researcher named Bruce Ivins, is dead by suicide and some skeptics smell a conspiracy. Ask Keim if he thinks Ivins was the anthrax letters terrorist and he says he just doesn’t know.

“It remains to be seen,” Keim said Wednesday, shortly after arriving in Hamilton. “I feel like in our country the only way you convict somebody of a crime is through a jury trial. And that’s not going to happen in this case.

“I really regret his suicide.”
