FBI agents have found and are questioning a person of interest who may be connected to the ricin laced letters sent to New York Mayor Bloomberg and President Obama, a source familiar with the case told ABC News.
The FBI were tipped off by the man's wife after she found a strange substance in her refrigerator and noticed that the search history on her computer contained searches for ricin. The man being questioned is from New Boston, Texas, which is located about an hour and a half drive away from Shreveport, La., where the letters were sent from.
One letter was sent to Bloomberg's office in New York City and a second letter was sent to an office for the anti-gun advocacy group Mayors Against Illegal Guns in Washington D.C., according to the Washington Post. A similar letter was also sent to President Obama.
The letters never made it to their intended recipients and according to the U.S. Postal Service they never posed a health threat, ABC News reports.
ABC News obtained a picture of the letter sent to Bloomberg's New York office, which can be seen here. The letter contains a pinkish substance smeared on it, authorities suspect that substance is ricin.
All three letters were identical and contained an anti-gun control message.
"You will have to kill me and my family before you get my guns," the letter said. "Anyone wants to come to my house will be shot in the face. The right to bear arms is my constitutional God-given right and I will exercise that right 'til the day I die. What's in this letter is nothing compared to what I've got planned for you."
Shreveport Mayor Cedric Glover said on Friday morning that the city's law enforcement will be doing everything they can to assist the FBI and the Joint Terrorism Task Force apprehend the person responsible for sending the letters.
"We are also taking the necessary steps to protect local [Postal Service] and Government Plaza personnel as well as local citizens from any possible harm," Glover said to ABC News.
Ricin tainted letters have been sent to the president in the recent past. Everett Dutschke was arrested April 28 for sending ricin laced letters to the president and other federal officials.
