UNDATED -- A Texas man is being interviewed by investigators in connection with letters believed to be laced with ricin.
Investigators were in and out of the home of Nathaniel Richardson today.
Authorities have questioned Richardson and his wife. Sources say his wife told authorities she found a suspicious container and ricin research on their computer.
One neighbor, Teri Hudgins, says, "it's scary, I'm hearing he's got something to do with what went to the President. I don't have much more information on it, first time we've had cops down here.."
The letters mailed to president Obama and New York City mayor Mike Bloomberg were postmarked from a post office in Shreveport, Louisiana.
That postal center handles mail from three states: Texas, Arkansas and Louisiana.
