Could the Ft. Lauderdale Airport shooter have any connection to Islamic jihadis?

JUST IN: Suspected Gunman Told FBI He Was Being Forced To Fight For ISIS

CBS  Officials said the gunman in a deadly attack at Fort Lauderdale-Hollywood International Airport checked in his weapon from a flight arriving from Canada. Esteban Santiago-Ruiz, 26, has been named as the suspected shooter.

According to Broward Commissioner Chip LaMarca, Esteban-Ruiz was a passenger on a Canadian flight with a gun that he checked in. “He claimed his bag and took the gun from baggage and went into the bathroom to load it. Came out shooting people in baggage claim,” LaMarca said.

On the company’s Twitter account, Air Canada confirmed that no one by that name was on their flight. Air Canada flights arrive to Terminal 2, where the shooting took place.

Law enforcement said he was found with an active military ID and is an American citizen, born in New Jersey. Previous known addresses include Penuelas, Puerto Rico and Anchorage, Alaska.

They add that in November 2016, he walked into an FBI office in Anchorage claiming that he was being forced to fight for ISIS. He was sent to a psychiatric hospital.

UPDATE: Fort Lauderdale Airport shooter lived within walking distance of the ONLY mosque in Alaska.
