The FBI is probing whether suspected Boston bomber Tamerlan Tsarnaev’s widow knew about his deadly marathon plot, a law-enforcement source told The Post yesterday.
Federal agents yesterday made three visits to the Rhode Island home of the parents of Katherine Russell, 24, an all-American-girl-turned-terrorist’s-bride.
During the first encounter, the agents were in the home for about 10 minutes.
A couple of hours later, The Post observed the same agents — two men and a woman — briefly speaking with Russell’s mom, Judith, through the door. Russell, who has a 3-year-old daughter, Zahara, with Tsarnaev, 26, is believed to have been inside.
ALL EYES ON HER: Katherine Russell, widow of slain Boston Marathon terror suspect Tamerlan Tsarnaev, rushes Saturday from the Cambridge, Mass., home where he lived.
One of the male agents was carrying a manila envelope, books and papers and walked away again with them after the brief chat with the mom.
In their final visit last night, the agents spent two hours in the house before leaving, followed by the family’s lawyer, Amato DeLuca.
“We just did some talking. We’re doing our best to try to deal with a very difficult situation. The family is going through a lot,” DeLuca said.
He refused to say whether the agents were with the FBI, ATF or ICE, confirming only that they were with the feds.
“Other than a brief interview with the FBI, there has been nothing more than that,” DeLuca told The Post. “Quite frankly, she was married to that man, so it doesn’t surprise me that they would do something of an investigation.’’
DeLuca later told The Post, “Katherine is innocent, and she has no knowledge of any of this.”
Federal agents had been by the parents’ house on Friday, as well, according to the Daily Mail.
Russell learned her husband was implicated in the terror attack by watching TV, DeLuca said. He did not say whether she identified him for authorities after they posted his image.
Meanwhile, a law-enforcement source told The Post the FBI is scouring video of the marathon and showing Russell’s picture to witnesses to see if she was at or near the finish line when two bombs ripped through the crowd last Monday, killing three people and injuring nearly 200 others.
“We’re looking at [footage] and showing the photo,’’ the source said.
