The Texas man questioned by the feds in connection with ricin-laced letters sent to Mayor Bloomberg and President Obama was let go yesterday — after he wildly claimed his actress wife sent the poisoned screeds, The Post has learned.

Investigators found castor beans — used to make ricin — in suspect Nathaniel Richardson’s car, but the 33-year-old Army veteran was allowed to leave a Texarkana federal courthouse because authorities don’t have enough evidence to hold him, sources said.

Richardson was grilled for hours after being arrested Thursday at Red River Army Depot, where he works, and is “still a suspect,” a source said.

But during questioning, Richardson insisted to the FBI that his pregnant wife, Shannon Rogers Guess, 36, hatched the diabolical plot, according to sources.

Both will be given polygraph tests, a source said.

Guess — who has had parts in “The Vampire Diaries” and “The Walking Dead” — was brought in for questioning at the courthouse yesterday.

The flame-haired, thrice-married mom of five is the one who called police to the couple’s New Boston, Texas, home after she found “Tupperware with what looked like ricin in the refrigerator,” a source said.

“He says they are going through a divorce and that she was away for a few days,” said one law-enforcement source. “He says it was when she got back that she found the [purported] ricin.”

The beans were bought with a credit card, according to a source.

Richardson allegedly told the FBI he does not use credit cards.

Agents escorted Guess into the courthouse, wearing tight jeans, platform shoes and a tight blue tank top that showed off her obviously pregnant belly.

Late Thursday, Guess had been with agents at the couple’s home as they carried out electronics and computers.

Richardson had not been on the feds’ radar until Guess called them, a source said.

In addition to the refrigerated ricin, Guess also claimed she had discovered directions on “how to make ricin” in the house and that somebody had Googled Obama and Bloomberg on the home computer, according to sources.

“You will have to kill me and my family before you get my guns,” the missive sent to Bloomberg read. “What’s in this letter is nothing compared to what I have planned for you.”

The letters, which were also sent to the anti-illegal-gun nonprofit Bloomberg helped found, were all sent from Shreveport, La., which is about 100 miles from New Boston.

While his wife was still being interviewed by agents, Richardson left the courthouse with his father. He declined to comment yesterday at a relative’s home.

Guess, who has five sons from previous relationships, could not be reached for comment.
