Shamsud-Din Jabbar visited the sight of his New Year’s Day terrorist attack in New Orleans, Louisiana, twice before, scouting out the area with smart glasses, authorities said on Sunday.

At a press conference, Deputy Assistant Director Christopher Raia and Lyonel Myrthil, FBI special agent in charge of the New Orleans Field Office, released new details about Jabbar and last week’s vehicle ramming attack that killed 14 and wounded 35. One of the biggest revelations was that Jabbar had scouted out the sight of his mass killing two times previously, using sophisticated glasses to map the area out.
