AP reporting that second suspect was not involved in the shooting:

Airport police detained and questioned a man who was acting suspiciously in the terminal, but he was not considered a suspect, Cmdr. David Kalish said. The man was picked up on a different level of the terminal, and was not believed connected to the shooter, he said. "There are no other suspects," Kalish said
