A woman deported to Mexico despite having legal permission to remain in the U.S. since she was a child has filed suit against the federal government.

The three Treviño children have suffered from panic attacks and nightmares since a mass shooting a year ago this week left 19 of their schoolmates and two teachers dead. Their parents are striving to help their kids feel normal again.

At least $14 million has been raised through multiple sources for the victims and survivors of the May 24 mass shooting at a Texas elementary school.
