Investigators probing the deadly New Year's Day terror attack in New Orleans say suspect Shamsud-Din Jabbar flew an ISIS flag on the back of the pick-up truck he used to mow down dozens of innocent revelers – killing at least 14 of them.
Jabbar, a former Army veteran who served in Afghanistan, joined ISIS before this summer and posted several videos on Facebook declaring support for the group before he carried out the heinous attack, FBI Deputy Assistant Director Christopher Raja said on Thursday.
