Shamsud-Din Jabbar, a U.S. citizen from Beaumont, visited New Orleans twice before the attack and recorded video of the French Quarter with hands-free glasses, an FBI official said in a press conference Sunday. Jabbar was wearing those glasses during the attack on New Year's Day, but they did not appear to be activated, police say.

The man who plowed a truck down Bourbon Street in a New Year’s Day terrorist attack visited New Orleans twice before and traveled to Egypt prior to the massacre.

A semiautomatic rifle recovered from the killer was purchased from a private seller in Arlington, Texas, the FBI said in a press conference.
