George Piro, FBI special agent in charge of the Miami Division, says they have not ruled out terrorism after an Iraq war veteran, identified as Esteban Santiago, killed five people at Fort Lauderdale's airport on Friday.
"We are looking at all avenues. We have not ruled out terrorism and we will be pursuing every angle to try to determine a motive behind this attack," Piro said during a news conference in Florida.
Officials say Santiago took a gun out of his checked luggage and opened fire in a crowded baggage claim area at Fort Lauderdale's airport. He was on a flight that left Anchorage, Alaska. And Piro says, he was known to authorities.
"The individual did walk into our Anchorage office in November. He came in and spoke with FBI agents. At that time, he clearly stated that he did not intend to harm anyone however his erratic behavior concerned FBI agents that were interviewing him," Piro said, adding that Santiago was taken for a mental health evaluation at that time.
