The FBI confirmed during a Thursday press conference that suspect Shamsud-Din Jabbar acted alone, walking back on its claims that Jabbar likely worked with others to carry out the deadly New Year's Day terrorist attack on New Orleans' Bourbon Street.

The FBI said it searched a location in Houston in connection to the New Orleans truck attack that killed 15 people.

In a news conference on Jan. 2, FBI Deputy Assistant Director Christopher Raia said the attacker was “100 percent inspired by ISIS.”
