NEW BOSTON, Texas (AP) A law enforcement official says a Texas home has been searched and a resident interviewed as part of the investigation into ricin-tainted letters sent to New York City's mayor and President Barack Obama.
Authorities blocked off the house in New Boston for hours Friday and set up tents in the yard while searching for evidence.
FBI agents entered the home wearing white hazardous materials suits and ventilation masks. New Boston is located near the Oklahoma and Arkansas borders.
The law enforcement official says the FBI initiated the search after being contacted by the resident's spouse. The official wasn't authorized to disclose information about the probe and spoke to The Associated Press on Saturday on condition of anonymity.
An FBI spokesperson in Dallas wouldn't comment.
No suspects have been named.
