The man accused of driving a pickup truck into a crowd on Bourbon Street in New Orleans’ French Quarter on New Year’s Day, which left at least 10 people dead and injuring dozens of others, has been identified, federal officials said.

The suspect in the attack was identified as 42-year-old, Shamsud-Din Jabbar, a U.S. citizen from Texas, the Federal Bureau of Investigation, FBI said in a statement. Officials said he crashed the white Ford truck around 3:15 a.m., then opened fire on responding police officers, which left two officers critically wounded. However, he was killed in the gunfight.

“An ISIS flag was located in the vehicle and the FBI is working to determine the subject’s potential associations and affiliations with terrorist organizations,” the FBI statement said.

Authorities have called the French Quarter attack that killed at least 10 people and injured 35 others an act of terrorism.

Alethea Duncan, FBI special agent told reporters the ISIS flag was hanging from the truck trailer’s hitch. She also said the bureau does not believe Jabbar was “solely responsible” for the attack. The vehicle used by the attacker is believed  to have been rented.

Jabbar, an Army veteran, also had weapons and a potential improvised explosive device in the rented truck, the FBI said. They also confirmed there were other possible IEDs planted nearby in the city’s French Quarter, with two rendered safe.

Jabbar served in the Army on active duty from 2006 to 2015 and then in the Army Reserves from 2015 to 2020, according to three U.S. defense officials. He had deployed to Afghanistan in 2009 and was a Staff Sergeant when he separated with an honorable discharge in 2020, the officials said.
