Shamsud-Din Jabbar, a U.S. citizen from Houston, also traveled to Cairo, Egypt, as well as Ontario, Canada, before the attack, although it was not yet clear whether those trips were connected to the attack, Deputy Assistant Director Christopher Raia said at a press conference.

According to an FBI update, the New Orleans attack suspect's rented vehicle was seen in Gonzales at around 9 p.m. on New Year's Eve.
