They were still investigating why the group was at the airport, and whether they were traveling or were there for some other reason. The gunfire led to the temporary closure of a security checkpoint at the terminal, the closure of some restaurants and a pause in service at the terminal's PHX Sky Train station. “Of course this was scary, this was Christmas evening, everybody's trying to get home,” Reeson said. In what Reeson described as a “completely unrelated” incident after the shooting and stabbing, a man showed up at the airport with a gun late Wednesday night. “This man received a text message that he believed there was an active shooter at Sky Harbor, Reeson said. That man then got into an altercation with a police officer and was arrested inside the airport. Reeson said he would be booked into jail. Information on his charges was not immediately available.
