Shamsud-Din Jabbar and Matthew Livelsberger had more in common than just using the same app to rent electric trucks used in New Year's explosive attacks.
The attack along Bourbon Street killed 14 people, along with the driver, Shamsud-Din Jabbar, who officials said was inspired by the Islamic State militant group.
The FBI said the suspect posted five videos on his Facebook account in the hours before the attack in which he aligned himself with IS and said he had joined the militant group last summer.
