Esteban Santiago Arrested Fort Lauderdale Airport Shooting

Esteban Santiago, a U.S. citizen and military veteran, may have heard voices telling him to fight for ISIS before he allegedly gunned down at least 13 people, killing five, at a Fort Lauderdale-Hollywood International Airport baggage claim area.

The shooter arrived Friday afternoon at the busy airport on a flight from Anchorage, Alaska, and the gun used in the shooting was in his checked baggage lawfully, NBC News reports.

His flight departed Anchorage, stopped over in Minneapolis, Minnesota, and finally arrived in Fort Lauderdale, sources told NBC. Earlier reports he flew through Canada turned out to be false. CBS News gave his name as Esteban Santiago-Ruiz.

Police said in a news conference that it was too soon to say whether the motive had any link to terrorism.

Pete Williams of NBC later reported that authorities contend the shooting appears to be the result of a “mentally disturbed person and not an act of terrorism.” He also reported that the shooter, whose roots are in Puerto Rico, served in Iraq and returned mentally unstable. The accused shooter had prior contact with the criminal justice system in Alaska.

According to NBC Miami, eyewitnesses reported that the active shooter – who is now in custody – killed the five people and injured eight while moving methodically down the carousel in the baggage claim area.
