The man responsible for a deadly attack on Bourbon Street in New Orleans has been identified as Shamsud-Din Jabbar, a U.S. citizen from Texas, the FBI said in a statement. He previously served in the U.

"We believe that the transmitter would have functioned and would have worked were it not for the actions of those New Orleans police officers."

The FBI has a better grasp of suspect Shamsud-Din Jabbar's whereabouts before the deadly New Year's Day attack. They said he visited NOLA twice, recording Bourbon Street using META glasses.
