LOS ANGELES » Federal prosecutors say three people connected to one of the San Bernardino shooters have been arrested in a marriage fraud conspiracy.

The U.S. Attorney’s Office said today that those arrested include the brother and sister-in-law of shooter Syed Rizwan Farook. The third person arrested is the wife of Enrique Marquez Jr., a friend of Farook’s who has been charged for his alleged role in aiding the violence.

The two women arrested are Russian immigrants.

Prosecutors say the three participated in a marriage fraud conspiracy that involved lying under oath to obtain immigration benefits.

Attorneys representing the Farook family didn’t immediately return calls for comment.
