NEW ORLEANS -- Law enforcement agencies are expanding their investigation into the New Year's ramming attack on New Orleans' Bourbon Street which killed 14 people and injured dozens more in the early hours of Wednesday.
City and federal officials said an Army veteran -- identified as Shamsud-Din Jabbar, 42 -- was "hell-bent" on killing as many people as possible. The suspect drove a pickup truck around a parked police car serving as a barricade and plowed into crowds of revelers, officials said.
The alleged attacker then exited the damaged vehicle armed with an assault rifle and opened fire on police officers, law enforcement officials said. Jabbar was also armed with a handgun, sources told ABC News.
Officers returned fire, killing Jabbar, a U.S.-born citizen from Texas, sources said.

In the first video, he explains he originally planned to harm his family and friends but was concerned the news headlines would not focus on the "war between the believers and the disbelievers."
This is also when he states that he joined ISIS before the summer.
He also provided a last will and testament.
Jan 1 at 2:03 a.m. CT: Surveillance footage shows Jabbar as he walked along Dauphine Street near Governor Nicholls Street. He is dressed in a light brown long coat, a dark-colored button-down shirt, blue jeans and what appears to be brown dress shoes. The FBI says Jabbar is seen placing devices inside coolers near Bourbon Street before the attack. They believe he acted along and changed clothes, law enforcement officials say.
Jan 1 at 3:02 a.m. CT: Jabbar posts his last of the five videos.
Jan 1 at 3:15 a.m. CT: Jabbar opened fire after ramming pedestrians on Bourbon Street.

The items were found when agents executed a search warrant at Jabbar's home in the small community of Greenspoint, in north Houston.
At a press conference Thursday morning, authorities said the New Year's truck attack on Bourbon Street killed 14 people.
The suspect -- 42-year-old Army veteran Shamsud-Din Jabbar, also died in the attack.
The death toll is not expected to rise, authorities said.
At a press conference Thursday morning, Christopher Raia of the FBI called the attack a premeditated "act of terrorism."
Louisiana Gov. Jeff Landry on Thursday compared the investigation to a jigsaw puzzle.
Over 400 tips have been submitted, Raia said Thursday. More than 1,000 law enforcement officers have been "pouring over countless amounts of data, of videos, of surveillances, interviews, tracking down every possible lead," Landry said.
The FBI and New Orleans police no longer believe there are any other suspects involved in the carrying out of the attack on Bourbon Street, multiple law enforcement sources told ABC News.
After investigators reviewed all of the surveillance videos more closely it appears that the driver placed the IEDs himself and then changed clothes. Those clothes were found in the vehicle, the sources said.
The FBI is still investigating whether there were individuals Jabbar spoke to or messaged with prior to the attack but no one was in the vicinity to help him do anything, the sources said.
The coroner's office has positively identified all of the victims.
The New Orleans Pelicans were in Miami when they learned of a deadly terrorist attack.
New Orleans plays its home games about 1 mile southwest of the intersection of Bourbon Street and Canal Street.
"I'm devastated," Pelicans coach Willie Green said.
Green got a text from his father early Wednesday. The first part wished him Happy New Year. The second offered prayers for New Orleans. That's how he found out about the horror happening in his city.
"A senseless act of violence," Green said. "We've discussed it a bit with our players. But we're just living in times and in a world where you just don't know where you're safe. Schools, churches, people should be able to go out and have a good time and walk the streets. It's devastating. And I can only imagine what those families are going through, what they have to deal with now for the rest of their lives."
The Pelicans are scheduled to play at home on Friday against Washington. The attack forced a one-day delay of the Sugar Bowl between Notre Dame and Georgia, a College Football Playoff quarterfinal. Originally set for Wednesday night, it was moved to Thursday afternoon.
