Five people were killed in a mass shooting in the baggage-claim area of Terminal 2 at Florida’s Fort Lauderdale International Airport just before 1 p.m. on Friday. Dozens of others were injured, Broward County Sheriff Scott Israel said in a Friday night news conference.

The suspected attacker, identified by Florida Sen. Bill Nelson and other officials as 26-year-0ld Esteban Santiago, was shot by police and taken into custody. Santiago is now in federal custody and is expected to appear in court on Monday.

NBC’s Pete Williams reported that Santiago had signed up to serve in the National Guard in August 2016 and had been living in Alaska. He was born in New Jersey, Williams reported, and his family was originally from Puerto Rico.

The suspect is in federal custody. Broward County Sheriff Scott Israel confirmed that there were no additional incidents in any of the other terminals.

“At this point it looks like he acted alone,” he said of the suspect. Investigators said terrorism has not been ruled out as a possible motive.
