As the FBI continues to investigate the couple who carried out the San Bernardino shooting last week the bureau is now questioning if their marriage was merely a cover.
Investigators revealed that Syed Rizwan Farook and his wife Tashfeen Malik were radicalized years before the attack that killed fourteen people — before they even met each other.
"As early as the end of 2013, they were talking to each other about Jihad and martyrdom before they became engaged and then married and lived together in the United States."

The information comes as the Department of Homeland Security is reviewing its fiancé visa program "to assess possible program enhancements," as some speculate that other would-be jihadists could use similar sham marriages to enter the country under less scrutiny.
"This visa has been totally under the radar," Marc Rosenblum, deputy director of the U.S. Immigration Policy Program at the Migration Policy Center, explained to the Associated Press this week. "The issue of marriage fraud has definitely gotten a lot of attention, just not as a security vulnerability."
In California, Investigators are also questioning Enrique Marquez---the friend and neighbor who purchased the two assault rifles used in the attack.
According to marriage records, Marquez and Farook had a sister-in-law in common.
Marquez has told investigators that he and Farook plotted an attack in 2012 but terror-related arrests in the area prevented them from carrying out their plans.
ABC News reports that the FBI is also questioning Marquez's marriage to Mariya Chernykh — saying that other than a marriage license, there is very little evidence that the two were a real married couple.
Authorities say they may bring gun charges against Marquez.
