New Video Shows Initial Moments Of Deadly Fort Lauderdale Airport Shooting

FORT LAUDERDALE, Fla. (CBSNewYork/CBS News) -- New surveillance video obtained by the website TMZ shows Esteban Santiago-Ruiz reaching into his waistband, pulling out a loaded gun, and firing the first three shots in the Friday rampage that left five people dead and injured six more at Fort Lauderdale-Hollywood International Airport.

The airport has since been cleaned up, but several cruise passengers returning to New York said it was eerie being at the scene.

"It's hard to explain but you just know how terrible the scene was here," West Falls, NY resident Linda Bettinger said. "You just understand what the families back home are going through with loved ones, injured or deceased, so it's hard."

Four of the five victims who died Friday have been identified. CBS2 learned Saturday that one of the victims who died was from New Jersey. Terry Andres, of Virginia Beach, was on vacation with his wife for his 63rd birthday.

A Florida woman says a man from Rochester -- Anthony Bartosiewicz -- selflessly shielded her with his body when Santiago-Ruiz allegedly opened fire.

"He just spoke calmly and quietly, 'I will protect you'," she said. "We just consider him a living guardian angel."

Bartosiewicz left on a cruise Saturday. His son Tony spoke to CBS2's Tony Aiello about his dad's actions.

"A huge feeling of pride that someone would do this in a situation like this that, it was my dad that actually did it," he said. "I have a feeling this is somethin that's going to stick with him for a while. It's, I think it's a life-changer."

Law enforcement sources have told CBS2 that the Fort Lauderdale airport shooting suspect picked the Florida airport at random and did not have any prior linkage to that airport.

Suspected Fort Lauderdale Shooter Esteban Santiago-Ruiz: Five Fast Facts

The shooting was reported just before 1 p.m. Friday at Fort Lauderdale-Hollywood International Airport in the baggage claim area of Terminal 2, which is used by Delta Airlines and Air Canada.

Santiago-Ruiz was arrested without incident after the shooting and was in police custody Friday night. Sources said there was no nexus to terrorism with the shooter, but terrorism has not been ruled out as a motive.

Santiago-Ruiz, 26, was born in New Jersey, law enforcement sources told CBS News. Santiago-Ruiz spent most of his time in Puerto Rico before going to Anchorage, Alaska.

Sources told CBS News a man meeting Santiago-Ruiz's description, and who is believed to have been Santiago-Ruiz, walked into FBI offices in Anchorage two months ago and said the government was forcing him to watch ISIS videos. Agents were apparently so concerned about him they took him to a mental health facility, CBS News' Scott Pelley reported.

Sources also told CBS2 the 9mm handgun Santiago-Ruiz had when he walked into the FBI office in Anchorage is the same weapon he allegedly used in the Fort Lauderdale attack.

Senator Chuck Schumer says after the attack, its clear that the front lines of security at airports needs to extend throughout the entire facility -- not just the point after the check in desk, WCBS 880's Mike Smeltz reported.

"We've been very secure on the other side, we gotta make this side secure," Schumer said. "We thought after 9/11 we couldn't stop what they did -- we've done a pretty good job, knock [on] wood."

Schumer also says gun laws need to strengthen, specifically in this case where the suspected shooter is reported to have suffered from mental health issues, but was legally allowed to carry a gun.

Sources say the investigation into the incident is still in its early stages and officials are looking to speak to anyone who may have known or been in contact with Santiago-Ruiz before the attack.

Investigators are also reviewing his communication and financial records.

Santiago-Ruiz has been charged with an act of violence at an international airport resulting in death -- which carries a maximum punishment of execution -- and weapons charges. He is expected to appear in court in South Florida on Monday.
