Police say they recovered the stark black banner of the Islamic State extremist group from the truck that an American man from Texas smashed into New Year's partygoers in New Orleans' French Quarter Wednesday, killing 15 people.
The investigation is expected to look in part at any support or inspiration that driver Shamsud-Din Jabbar may have drawn from that violent Middle East-based group, or from any of at least 19 affiliated groups around the world.
