Officials are questioning a Texas Army veteran over ricin-laced letters sent to President Obama, Michael Bloomberg, and Bloomberg's gun-control organization, law enforcement sources tell NBC New York. The man, who works as a Pentagon contractor, isn't a suspect in the case at this point, they say. He does, however, have links to Shreveport, Louisiana, where the letters were postmarked. Meanwhile, the text of the letters is emerging: "What's in this letter is nothing compared to what I've got planned for you," they all say, per NBC New York.
"You will have to kill me and my family before you get my guns. Anyone wants to come to my house will get shot in the face," the letters say. "The right to bear arms is my constitutional God given right." More suspicious letters are also under investigation in New York City, though they're reportedly not tied to ricin concerns. Meanwhile, the FBI is looking for yet another letter tied to the ricin scare, this one addressed to the CIA. Earlier this month, authorities found three similar letters containing ricin directed to Obama, a federal judge, and a post office; one sent to Fairchild Air Force Base is being tested for the substance. Matthew Ryan Buquet, 37, was arrested in connection with the letter to the judge, CNN reports. (Read more ricin stories.)
