A Texas woman was arrested in connection to sending ricin-filled letters to President Obama, New York Mayor Michael Bloomberg (I), and the director of Bloomberg's anti-gun group.
Shannon Richardson of New Boston, Texas was charged with sending a "threatening communication" to President Obama.
According to the affidavit of the arrest, Richardson allegedly sent three letters with the poisonous substance: to Bloomberg in New York City; and to Obama and Mark Glaze, the head of Mayors Against Illegal Guns, both in Washington D.C.
Richardson was arrested Friday in Mt. Pleasant, Texas. She faces up to 10 years in prison if convicted, authorities said.
Prior to the arrest, FBI agents in hazardous materials suits were spotted at Richardson's house on Wednesday, according to the Associated Press. Agents reportedly searched Richardson's house after a neighbor contacted the FBI.
The arrest follows law enforcement officials moving forward with a separate case against a man believed to have sent letters containing the poisonous ricin to Obama, a Mississippi judge and Sen.
