The New Orleans attacker visited the city twice in the months prior to New Year’s, and used Meta smart glasses to film Bourbon Street and plan out his attack, FBI New Orleans Special Agent in Charge Lyonel Myrthil said Sunday.

The man who drove a truck into a crowd of people in New Orleans on New Year’s Day, killing 14, had previously scouted the French Quarter and recorded video with his Meta smart glasses, the FBI said.
