A
series of videos posted by the man responsible for the deadly New Year's attack in New Orleans reveal his plans and motivations, according to officials briefed on the investigation. Shamsud-Din Jabbar, 42, drove a pickup truck into a crowd of revelers on Bourbon Street, killing 14 people and injuring dozens more.

    In the videos, Jabbar discussed planning to kill his family and having dreams that inspired him to join ISIS, officials said. He made reference to his divorce and initially planned to gather his family for a "celebration" with the intention of killing them, but changed his plans to focus on the "war between believers and disbelievers." Jabbar stated he had joined ISIS before this summer.

    The videos were posted on Jabbar's Facebook page in the hours leading up to the attack. He also planted two improvised explosive devices, which were later found by police. Jabbar was killed while exchanging fire with police after ramming the truck through the crowd.

    Jabbar's family is struggling to understand how he went from a military veteran to a suspect in a deadly rampage. His brother Abdur described him as "very well-tempered" and "slow to anger," making it hard for them to reconcile his actions with their memories of him.

    Jabbar served in the Army for over a decade, including a deployment to Afghanistan, and later worked in business development and data engineering at Deloitte. However, he had also struggled with finances and had several run-ins with the law, including a guilty plea for driving under the influence while serving at Fort Bragg.

    Jabbar rented the truck used in the attack from Turo, a car rental website that allows owners to rent their vehicles to others. The truck's owner confirmed that it was rented on Turo and picked up by Jabbar before he drove to New Orleans.
