Two U.S. law enforcement officials say Richardson, of New Boston, Texas, has been arrested in the investigation of ricin-laced letters sent to President Barack Obama and New York Mayor Michael Bloomberg.
The officials spoke on the condition of anonymity because they were not authorized to speak publicly during the ongoing investigation.
FBI agents wearing hazardous material suits were seen going in and out of her house Wednesday in New Boston, about 150 miles northeast of Dallas near the Oklahoma and Arkansas borders.
