NEW BOSTON, TX (CBS 11 NEWS) – Federal agents wearing hazmat suits searched a house in New Boston Friday.

They were looking for evidence connected to the letters laced with the poisonous ricin that were sent to President Barack Obama and New York City Mayor Michael Bloomberg.

Residents in New Boston said they don’t know what to make of all of the sudden activity.

“We’re in a town where most people know everybody. I know eight or ten families up and down this street, Maple Street here, and it’s just very surprising to us,” said resident Tommy Rainey.

But no one on the street CBS 11 spoke with said they know the couple who lives at the house with their five children that has attracted the FBI, U.S. Postal Inspectors and other federal agencies.

The small army of federal agents have been at the house more than a day now. The wife first called police to report suspicious activity and items inside her house.

CBS News reports she told investigators her husband may have sent the letters, but that her husband claims it was she who set him up.

Investigators told CBS the wife knows specific details about the letters.

But the FBI said it has neither named any suspects, nor taken the couple into custody.

“You never think something like this would happen in a small town, you just never know,” said Teri Rainey.

The letters were postmarked May 20 in Shreveport, Louisiana, an hour and a half away.

The letter to Mayor Bloomberg, who publicly supports tougher gun laws said:

“You will have to kill me and my family before you get my guns. Anyone wants to come to my house will get shot in the face. The Right to bare arms is my constitutional, God-given right and I will exercise that right till the day I die. What’s in this letter is nothing compared to what I’ve got planned for you.”

“Everybody has a right I believe to own a gun, but not for this reason,” said Teri Rainey.

Her husband said he doesn’t think someone has “a right to send the President a message like that.”
