One day after five people were killed at an airport in Fort Lauderdale, Fla., more details are coming to light on the suspected gunman: Esteban Ruiz Santiago, a U.S. military veteran.
The 26-year-old was arrested by police shortly after the shooting began at the airport's baggage claim area. He is now at a Broward County jail, where authorities say he is being held on suspicion of murder. Authorities say there is no indication that Santiago worked with anyone else in planning or executing the attack.
