Whatever happened in the anthrax letter investigation? No charges or convictions, just unanswered questions.

The investigation led FBI investigators to Fort Detrick, Md., and their person of interest, Steven Hatfill. He was a bioweapons research scientist familiar with this strain of anthrax. It was developed at Dugway, Utah.

Despite an intense investigation, Dr. Hatfill was never charged. But the fact remains: This form of anthrax is available only at Fort Detrick. If Dr. Hatfill didn't do it, someone else working there did. The investigation was halted when the guilty party obviously could have been nowhere else. Who stopped the investigation and why? These are not unreasonable questions.
