Police probe motive in New Orleans truck rampage

Investigators in New Orleans were searching on Thursday for what motivated a U.S. Army veteran flying an ISIS flag from his truck to plow into a crowd of New Year's revelers, killing 15 people and injuring 30 more before dying in a shootout with police.

The probe was focused on whether the suspect, Shamsud-Din Jabbar, 42, a U.S. citizen from Texas who once served in Afghanistan, had help in planning the deadly attack on a city that will host the NFL Super Bowl next month.

FBI officials said they were also looking for any links between the deadly attack and a separate incident on Wednesday in which a Tesla Cybertruck exploded in flames outside the Trump International Hotel in Las Vegas, just weeks before President-elect Donald Trump returns to the White House on Jan. 20.

The New Orleans attack injured about 30 other people, including two police officers wounded by gunfire from the suspect, taking place a mere three hours into the New Year in the historic French Quarter.

The victims included the mother of a 4-year-old who had just moved into a new apartment after getting a promotion at work, a New York financial employee and accomplished student-athlete who was visiting home for the holidays, and an 18-year-old aspiring nurse from Mississippi.

Witnesses described a horrifying scene.

"There were people everywhere," Kimberly Strickland of Mobile, Alabama, said in an interview. "You just heard this squeal and the rev of the engine and this huge loud impact and then the people screaming and debris - just metal - the sound of crunching metal and bodies."

Meanwhile authorities vowed to continue to search for any evidence that Jabbar had accomplices.
