San Bernardino shootings: 3 linked to shooter charged with marriage fraud

FBI agents arrested the brother of a man who carried out the December mass shooting in San Bernardino, Calif., as well as two women on Thursday on charges of federal conspiracy, marriage fraud and making false statements, U.S. prosecutors said.

Officials said the charges againstSyedRaheelFarook, whose brotherSyedRizwanFarookand sister-in-law, Pakistan-bornTashfeenMalik, killed 14 people at a Dec. 2 holiday party, follow an immigration-related investigation that began with the probe into the massacre.

Authorities have said that Syed Rizwan Farook and Malik were inspired by Islamic extremism, calling it the deadliest such attack on U.S. soil since Sept. 11, 2001. They died in a shootout with police hours after the mass shooting.

The three people arrested on Thursday were not charged with any crimes related to terrorism or the December shooting.

U.S. Navy veteran Syed Raheel Farook, 31, his wife, Tatiana Farook, 31, and her sister Mariya Chernykh, 26, were arrested by agents from the Federal Bureau of Investigation after they were charged in an indictment with conspiracy to make a false statement to immigration officials while under oath, the U.S. Attorney's Office said in a statement.

The investigation determined that in 2014 Enrique Marquez, who had been a friend of Syed Rizwan Farook, agreed to marry Chernykh, a Russian citizen, so that she could apply for permanent residence in the United States, charging documents stated.

Chernykh also was charged with fraud and two counts of making material false statements to federal agents, prosecutors said.

She submitted immigration paperwork declaring that she lived in Corona with Marquez, which was false because she lived in the nearby community of Ontario with her child and another man, according to charging documents.

Syed Raheel Farook and Tatiana Farook, who were arrested at their home in Corona, had staged photos of Marquez and Chernykh to make them look like a married couple and created a joint bank account for the two, the charging documents stated.

"Today's arrests open a new phase in the process of bringing to justice all individuals who allegedly committed crimes that were uncovered during our exhaustive investigation," U.S. Attorney Eileen Decker said in a statement.

Marquez was charged on Dec. 18 with conspiring with Syed Rizwan Farook in 2011 and 2012 to support a militant attack in Southern California that was never carried out. He has pleaded not guilty and is awaiting trial.

The alleged sham marriage of Marquez and Chernykh surfaced in December, when Marquez was charged with defrauding immigration authorities by entering into the union.
