The letter listed half a dozen calls that had been "ignored" by operators answering phones at the command center in Rockville, the Montgomery County police station and the FBI. It even named some of the people who had taken his calls.
They had hung up, the letter stated; that was "incompetent."
"Five people had to die" because of it, the letter said, according to one law enforcement source who has seen a copy of the letter.
The letter gave a deadline of Monday for the money to be deposited in a bank account, the source said. Several people who had seen photocopies of the letter said the amount demanded was $10 million.
