Shamsud-Din Jabbar, a Texas Army veteran, drove a truck with an Islamic State flag into a crowd of New Year’s revelers on New Orleans’s Bourbon Street, killing 15.

The truck used in the early morning attack had a Texas license plate. A man, who would not identify himself, at the Pasadena address connected to the license plate did not answer questions when approached by KHOU 11 News. He only confirmed that the vehicle had been rented out.
