NEW BOSTON, TX - FBI agents combed a Texas home Saturday as part of an investigation into the ricin-laced letters sent to Mayor Michael Bloomberg and President Barack Obama.
A law enforcement official said the home in New Boston, Texas was blocked off for hours as federal investigators searched for evidence.
Agents were seen wearing hazmat suits and ventilation masks.
The official said a resident was also interviewed.
The search was initiated by the FBI after it was contacted by the resident's spouse.
A letter was also sent to Bloomberg's anti-gun lobby in Washington.
No suspects have been named.
