Shamsud-Din Jabbaar came to New Orleans on November 10 by train to look at an apartment for rent on Orleans street in the French Quarter but told the landlord that he changed his mind after applying to rent it.

Shamsud-Din Jabbar, the driver behind the Bourbon Street attack on New Year’s, researched New Orleans and the deadly Christmas market attack in Germany in the hours and weeks before the attack, the FBI said in an update Tuesday.
