BEAUMONT, Texas — Shamsud-Din Jabbar grew up in Texas, joined the U.S. Army and eventually settled in Houston, where he spun up a real estate business and made $120,000 a year for one of the world's largest consulting firms.
But the 42-year-old U.S. citizen, who authorities say plowed a rented truck through New Year's revelers in New Orleans before being shot and killed by police, also faced pressures. He finalized a third divorce in 2022, saying in filings he couldn't pay his mortgage and his business was losing money.
On Thursday, authorities and relatives were still piecing together why Jabbar barreled through a crowd in a Ford F-150 on Bourbon Street, killing 14 revelers and injuring at least 30 others. Officials said the attack was inspired by the Islamic State group, making it one of the deadliest IS-inspired assaults on U.S. soil in years.
FBI officials said Jabbar posted five videos to his Facebook account in the hours before the attack in which he aligned himself with IS. Authorities also found an Islamic State flag on the truck used in the attack early Wednesday.
''It's completely contradictory to who he was and how his family and his friends know him," Abdur-Rahim Jabbar, one of his brothers, told The Associated Press on Thursday at his home in Beaumont, about 90 miles outside Houston.
The 24-year-old said his older brother had increasingly isolated himself from family and friends in the last few years but he hadn't seen any signs of radicalization when they talked. He said it had been a few months since he had seen his brother in-person and a few weeks since they talked on the phone.
''Nothing about his demeanor seemed to be off. He didn't seem to be angry or anything like that. He was just his calm, well-mannered, well-tempered self,'' the younger brother said.
Law enforcement officials said after driving into the Bourbon Street crowd and crashing the truck, Jabbar exited the car wearing a ballistic vest and helmet and fired at police, injuring at least two before he was shot and killed by officers returning fire.
