FBI reports lone attacker behind deadly New Orleans New Year's rampage

FBI confirmed that a U.S. Army veteran acted alone when he drove a pickup truck into New Year's crowds in New Orleans French Quarter, killing 14 people and injuring dozens more.

Christopher Raia, FBI's Counterterrorism Division, dismissed earlier concerns about potential accomplices who might have helped plant explosives in coolers throughout the popular tourist district. 

"We're confident, at this point, that there are no accomplices," Raia told reporters at a news conference on Thursday afternoon.

The attacker, identified as 42-year-old Shamsud-Din Bahar Jabbar from Beaumont, Texas, died in a police shootout following the early morning rampage on January 1. 

According to Raia, Jabbar had pledged allegiance to the Islamic State terrorist group in an online video before the attack.

Investigators said that Jabbar had initially planned to target friends and family members but changed course due to concerns about media coverage.

"He was 100% inspired by ISIS," said Raia.

New Orleans officials announced plans to reopen Bourbon Street and expressed confidence in security measures for Thursday afternoon's rescheduled Sugar Bowl.

While authorities are investigating a possible connection to Wednesday's Tesla truck explosion outside a Trump hotel in Las Vegas that left one person dead, Raia said no definitive link has been established. 

The investigation remains ongoing.
