It is the deadliest attack by ISIS on the West in several years. But still, almost a week later, the group also known as Islamic State has yet to issue its trademark claim of responsibility for the horrific New Year’s violence in New Orleans.

Recordings and interviews detail Shamsud-Din Jabbar’s growing discontent with American society and increasing isolation even within his local Muslim community.

The FBI said the suspect responsible for the New Orleans attack traveled from Houston on New Year's Eve before carrying out the attack.

Family members and friends have begun identifying the 14 people who died in the truck-ramming attack early Wednesday morning on Bourbon Street in New Orleans.

The 42-year-old U.S. Army veteran responsible was a Houston resident, who, prior to striking, pledged his allegiance to ISIS.
