Tashfeen Malik, the female shooter in the California massacre, was allowed to stay in America following a background check by the FBI and the Department of Homeland Security.

The 27-year-old Pakistani national, about whom many details are still sketchy, met Syed Farook, the other killer, over the Internet before he went to visit her in Saudi Arabia.

On the visit, during which authorities believe Farook was radicalized by terrorists, Farook and Malik apparently got married in Mecca, the Muslim holy city in the country, reported the Los Angeles Times.

When Farook, an American citizen whose parents immigrated from Pakistan, returned to the U.S., he brought Malik with him on a fiancee visa.
