New Orleans attack latest: No evidence at this time suspect had contact with ISIS, officials say

Witnesses described scenes of carnage in the wake of an attack early Wednesday morning on Bourbon Street in New Orleans that left 10 killed and 30 injured.

"We heard a 'pop, pop, pop, pop' sound, followed by a sound that sounded like fireworks going off, like a big firework all at once, and it turned out that was the crash," said Paul S., who asked ABC News to withhold his full name.

Paul said he peeked through the curtains to see what was occurring and saw police officers telling people in buildings to stay inside. He then went onto the balcony and started recording the aftermath of the attack.

"There's litter all over the sidewalks, and then there were bodies laid up next to garbage cans and people rushing to give aid," he said. "There were...these really bright lights out on Bourbon Street and that illuminated the scene where you could look up and down a block and see it completely empty except for the bodies that were on the ground."

Another witness, Jimmy Cothran, told ABC News' Morgan Norwood he and his group ducked into a Bourbon Street nightclub when the commotion began.

"Body after body mangled just as far as you could see. We counted 10, and at least six were instantly clearly deceased. Some were very clearly deceased, but others were yelling out. ... It's a lot to process," he said.

Cothran added that he saw some bodies in the street that bore tire marks.

New Orleans officials are investigating the identity of the suspect.

They said they have identified a name -- albeit a common name -- so authorities say they want to be certain that they have identified the right person before releasing a name.

After mowing down numerous people over a three-block stretch on the famed thoroughfare while firing shots into the crowd, the suspect allegedly got out of the truck wielding an assault rifle and opened fire on police officers, law enforcement officials briefed on the incident told ABC News. Officers returned fire, killing the suspect.

Police Superintendent Anne Kirkpatrick said the driver had attempted to kill as many people as possible. The truck used in the attack appeared to be a F-150 Lightning, an electric vehicle. A black flag appeared to be attached to the vehicle, but its significance was not immediately known.

"He was hellbent on creating the carnage that he did," Kirkpatrick said at a news conference early Wednesday.

President Joe Biden has released a statement on the deadly truck attack in New Orleans.

Full statement below:

"I have been continually briefed since early this morning by federal law enforcement leadership and my homeland security team, including Secretary of Homeland Security Ali Mayorkas, Deputy Attorney General Lisa Monaco, White House Homeland Security Advisor Liz Sherwood-Randall, and the Mayor of New Orleans regarding the horrific incident that occurred there overnight. The FBI is taking the lead in the investigation and is investigating this incident as an act of terrorism. I am grateful for the brave and swift response of local law enforcement in preventing even greater death and injury. I have directed my team to ensure every resource is available as federal, state, and local law enforcement work assiduously to get to the bottom of what happened as quickly as possible and to ensure that there is no remaining threat of any kind."

"I will continue to receive updates throughout the day, and I will have more to say as we have further information to share. In the meantime, my heart goes out to the victims and their families who were simply trying to celebrate the holiday. There is no justification for violence of any kind, and we will not tolerate any attack on any of our nation's communities."

The F150 truck that was used in the New Orleans attack was a vehicle rented through the Turo app - a carsharing company, ACB News has learned.

The truck's owner told ABC News that he rented this truck to an individual through Turo and that he is currently talking to the FBI, declining to comment further.

The truck owner's wife said they are devastated.

"My husband rents cars through the Turo app. I can't tell you anything else. I'm here with my kids, and this is devastating," she said.

ABC News has reached out to Turo for comment.
