SAN BERNARDINO, California — A brother-in-law of one of the San Bernardino shooters said the Christmas party massacre was "a personal act" unconnected to the culprit's Muslim faith and described him simply as "a bad person." Farhan Khan said he had "no idea" what led to Wednesday's rampage, in which 14 people were killed. He added that Syed Rizwan Farook and his wife, Tashfeen Malik, were "a happy couple" who loved their baby daughter. The tot was left with her grandmother before the mass shooting.
