Shamsud-Din Jabbar, a Texas-born citizen, spent 15 years serving in the U.S. Army before leaving to work in IT and Human Resources. Twenty-four hours before a New Year’s celebration on the streets of New Orleans, Lousiana, Jabbar rented an F-150 Lightning on Turo and drove it from Texas to Louisiana.

During the drive, ABC News reports he posted videos to social media describing his inspiration from ISIS and mentioned a “desire to kill.” Investigators later found an ISIS flag on the hitch of the rented EV pickup.

Around 3 a.m. on New Year’s Day, witnesses and investigators say Jabbar drove around a parked police cruiser and drove into the crowd. After killing 15 and injuring 30 attendees with the truck, he exited the truck and fired at officers with an assault rifle.

Police returned fire and killed Jabar, injuring two officers. Authorities discovered several IEDs in the rented truck and others planted around the area. Originally, Louisiana authorities said they didn’t think Jabbar acted alone due to the amount of explosives that were in the area, but the FBI said this morning he acted alone.

Officials called the attack an act of violence and terrorism

The association of ISIS and the presence of the flag prompted New Orleans officials to label Jabbar’s attack an act of terrorism. New Orleans Mayor LaToya Cantrell called it a “terrorist attack,” and the FBI is investigating it as an act of terror.

Louisiana Governor Jeff Landry wrote Jabbar’s attack was, “A horrific act of violence,” and that he and his family were praying for the victim’s families.

President Biden said his administration will update the public as more information becomes available, while President-elect Donald Trump described Jabbar’s action as “pure evil.”

Authorities wonder if there’s a connection to the Vegas Cybertruck explosion

Another army vet rigged a Tesla Cybertruck to explode in front of the Trump Tower shortly after the New Orleans attack. The blast killed two people and injured several others. FBI investigators are looking into a possible connection, as both attackers served on the same army base, Denver7 reports.

There isn’t any evidence to suggest the attackers were acquainted, though the FBI is investigating any possible ties.

The suspicion comes from the closeness in the timing of the attacks, as the Vegas attack happened just hours after Jabbar was gunned down by police.
