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 FBI says the New Orleans truck attacker who killed 14 people had previously scouted the French Quarter and recorded video with his Meta smart glasses

Shamsud-Din Jabbar wore the same Meta smart glasses when he carried out his New Year’s Day attack, but there’s no indication he was recording, authorities said.
