The threatening latter was received at an off-site facility and did not reach the recipient.
The text of that mailing was identical to the letters sent to the mayor and his gun group, which threatened: "what's in this letter is nothing compared to what I've got planned for you". It also had vows to protect a constitutional and God-given right to bear arms.
According to police, all three letters containing the deadly poison were sent May 20 from Shreveport, Louisiana and had no return address or signature.
Letters mailed to New York City Mayor Michael R. Bloomberg tested positive for the poison ricin, officials said Wednesday. Multiple sources reported that one of the letter contained references to the national gun control debate.
Investigators told the New York Times they believe both letters were sent by the same person. The second letter was addressed to the Washington building that hosts Mayors Against Illegal Guns, a gun control lobby group Bloomberg helps lead.
“The writer, in letters, threatened Mayor Bloomberg, with references to the debate on gun laws,” Pual J. Brown, the chief spokesman for the New York Police Department, told reporters Wednesday.
Both letters were intercepted before reaching Bloomberg and no reports of illness have surfaced. Members of the police department’s Emergency Service Unit who found the letter at a New York mail facility were examined as a precaution. Both envelopes were postmarked in Louisiana, according to CBS News.
The toxin can be fatal if ingested.
The Joint Terrorism Task Force and the police department’s Intelligence Division are investigating the situation.
Federal authorities are investigating threatening letters allegedly containing deadly ricin in Spokane, Washington, the FBI said. One letter was addressed to the Spokane Post Office and the other to a federal judge in Spokane. Both were postmarked May 14, the American Postal Workers Union said.
The FBI and the U.S. Postal Inspection Service are trying to find the source of the two letters, detected during a screening procedure at a postal facility in Spokane.
Postal Service employees were not at risk, as the deadly substance was not in the form that could be inhaled or readily ingested. Preliminary lab tests showed the substance to be ricin, the union said.
Less than a pinpoint of ricin can kill a person if inhaled, injected or ingested. A person dies within 36 to 48 hours because of the failure of the respiratory and circulatory systems. There is no known antidote.
Earlier, ricin-tainted letters were sent to the US President Barack Obama. James Everett Dutschke, 41, of Tupelo, Mississippi, was accused of sending poison-laced letters to senators and the president of the United States.
