But there is something goofy about this guy. I'd like to know what his motivations are, whether he is native born or not. (Tomas is an unusual spelling for a native-born American)
This still doesn't link him to much, since 'his' anthrax is regular old anthrax, not 'weaponized' anthrax, not hi-grade stuff. What killed people was the hi-grade stuff. It also isn't known if he sent any anthrax out at all, even low grade stuff- we only know he admitted to sending out hoax mails.
The question is, did he get the idea because of the real stuff being sent, was he working alone, or was he in conspiracy with the senders of the weaponized stuff? What was the motivation? The weird fascination of an arsonist-type, or that of a politically motivated person?
