A veteran, real estate agent, and Deloitte IT guru, Shamsud Din Jabbar, turned terrorist, attacked New Year's Eve revelers in New Orleans. He drove a pickup truck flying an ISIS flag into a crowd on Bourbon Street, killing 15 and injuring at least 25 more. Jabbar, 42, was born in Beamont, Texas, and grew up with two brothers. He first enlisted in the US Navy in 2004 but left before basic training started. Two years before the attack, Jabbar was living a normal American life, working hard, starting businesses, and was married with a family.
