At least 15 people were killed and dozens more were injured in what the FBI is investigating as a terrorist attack in New Orleans on New Year’s Day.

Shamsud-Din Jabbar was identified as the suspect who drove down a crowded Bourbon Street, killing at least 15.

Months before the deadly New Orleans vehicle attack on New Year’s Day, the city modeled scenarios for how an attacker could enter Bourbon Street at various intersections in a crew-cab Ford F-150 similar to the one used to kill 14 people and injure dozens more.
