Office, and the agents there were so concerned about what he was saying, they sent him to a mental hospital. David begnaud is in Fort Lauderdale and begins our coverage. Reporter this cell phone video captures the momentes after shots rang out at the baggage claim area in terminal number 2 of the Fort Lauderdale international airport. A lone gunman opened fire on passengers, leaving five people dead and eight injuredded. Some of the wounded found shelter outside while they waited for help. Hundreds more ran for safety on to the tarmac and airport roads, taking shelter near cars and up against buildings. Everybody took off, and they said they said a shooter. I mean reporter eyewitness mark lea was 10 feet away from the gunman. He, like i say, just walked into the door, did not yell, did not scream, just started shooting. We thought at first it was firecrackers and then we realized it was gunshots and by that time people were yelling and screaming and trying to get out of any door they could, hide under chairs, hide under luggage, anything else to get out of the line of fire. I heard a lady yell for help and i saw people running and i just ran. Reporter the shooter has been identified as 26yearold Esteban Santiago from anchorage, alaska. According to officials, he was carrying a military i. D. Eyewitnesses say the gunman ran out of ammunition and laid down when the police came and arrested him. One Broward County official is reported as saying the gunman was a passenger on an incoming flight. He retrieved his luggage at the baggage claim, walked into the airport restroom, loaded the gun, and then opened fire. Fort lauderdale sheriff scott israel we have the shooter in custody. Hes unharmed. No Law Enforcement fired any shots. The subject is being interviewed by a team of f. B. I. Agents and Broward Sheriffs Office homicide detectives. Reporter about an hour after the initial shooting, there were reports of more gun fire. Police moved in and people took off running yet again. But those reports were unfounded. There was also a bag found near a set of Railroad Tracks that was detonated. But, scott, were told that bag is not connected to the gunman. And if it looks really quiet behind me at the airport, thats because the air space is closed. No flights in or out of Fort Lauderdale right now. Pelley and the full details on all of this overnight on cbs this morning tomorrow. David begnaud, thanks very much. Josh has latebreaking information about the suspects background. What have you learned . Scott, heres what we know. Investigators say that Esteban Santiago has no known connection to trump and that the 26yearold new jersey native got into an argument on one leg of his travel from alaska to florida. The motive remains under investigation. Cbs news has also learned that two months ago, as you mentioned, santiago walked into an f. B. I. Office in anchorage, alaska, claiming that his mind was being controlled by the c. I. A. And the u. S. Government, and that he was being forced to watch isis videos. Anchorage police in a followup to that f. B. I. Encounter later sent santiago to a hospital for psychiatric evaluation. Santiago also has a long military history. He deployed to iraq it in 2010 and was a member of the alaska Army National guard, scott, until august of last year, when he was discharged for unsatisfactory performance. Pelley josh elliot covering the story all afternoon. Josh, thank you very much. We spoke earlier today with a witness to the shooting, mike starobinsky. He and his family were returning from a cruise. Pelley there was nothing to stop the shooter from doing what he did. Our transportation correspondent kris van cleave has the latest on gaps in Airport Security 15 years after 9 11. Reporter investigators believe the gun used in the baggage claim shooting was checked as luggage, something the t. S. A. Allows but requires the gun to be unloded and locked in a case. It and ammunition must be disclose to the airline prior to checking. Since 9 11, airports have seen a dramatic increase in security, but many parts of the terminals, like checkin and paggage claim, are outside the secured area and remain vulnerable soft targets. Ron hosko is a former assistant director of the f. B. I. One of the great challenges of a soft target is its like squeezing a balloon. And where i tighten up my security in one place, the balloon expands somewhere else, and presents itself as another soft target. Reporter and he says securing areas like baggage claim in every airport would be a multibilliondollar investment. We have to put it in that broader perspective. Youre more likely to die in a car accident on your way home than to be in ay terrorist strike at a u. S. Airport. Reporter immediately after the shooting, airports across the country increased security, that includes airports in the new york city area, miami, and los angeles. Scott, the l. A. X. Police chief said theyll look at Lessons Learned from Fort Lauderdale to look at the kind of changes they can make in laz to make the airport safer. Pelley some were told the safety place to be was in airports and they stayed on the planes for hours. Kris van cleave, thank you. In another major story tonight, u. S. Intelligence has concluded that russian president Vladimir Putin ordered his military to help donald trump win the election. Today, the director of National Intelligence took the unusual step of releasing an unclassified version of an investigation that details computer hack, propaganda, and fake news articles. President elect trump was briefed on the classified report today, but he concluded that the hacking of sensitive Democratic Party files had no effect on the election. Homeland security correspondent jeff pegues is following this. Reporter the 25page report states directly that russian president Vladimir Putin ordered an influence campaign in 2016 aimed at the u. S. President ial election. It started as a grudge against hillary clinton. Putin blamed the former secretary of state for inciting maz protests in russia against against his government in 2011. Payback was Information Warfare that was multifaceted. It included Twitter Campaigns, propaganda, and fake news. And the hacks of state and local electoral boards and the Democratic National committee. Todays report was a declassified versionave longer report that was shared with president obama and president elect trump. That classified document detailed interceptes of russian officials congratulating each other on Donald Trumps victory. It also identified the russian actors who gave stolen data from democratic officials to wikileaks. Investigators point to the close relationship between wikileaks founder Julian Assange and the Russian News Network rt, which airs in the u. S. The report says a Russian Media executive went to london in 2013 and met assange in person. U. S. Intelligence says rt and wikileaks have collaborated several times since. As mr. Trump became the g. O. P. Nominee, the name o nature of te russian activities changed. Theres nothing i can think of that id rather do than have russia friendly as opposed to the way they are right now. Reporter u. S. Officials believe putin and the russian government developed a clear preference for him, and then aspired to help president elect trumps election chances. But the kremlin still believed clinton would win, and it already put together a Twitter Campaign with the hashtag democracyrip, to discredit her victory. Late today, the department of Homeland Security declared election systems to be Critical Infrastructure which will give the agency greater oversight over their cybersecurity. But, scott, no one believes the russian attacks compromised the vote tally. Pelley jeff pegues in the washington newsroom, jeff, thank you very much. Mr. Trump was briefed today by the directors of National Intelligence, the f. B. I. , the c. I. A. , and the National Security agency. Jan crawford has that. Reporter calling the the briefing with top intelligence officials constructive, donald trump acknowledged russia, china, other countries, outside groups, and people are continuously trying to mount cyberattacks against the u. S. But he declined to say whether he accepted the Intelligence Communitys conclusion that Vladimir Putin directed the attack. On thursday, director of national intecialtion james clapper, who is among top officials briefing mr. Trump, stopped short of saying the hacks had an impact on the elections outcome. Certainly the Intelligence Community cant gauge the impact it had on choices the electorate made. Theres no way for us to gauge that. Reporter in a statement, mr. Trump was adamant. There was absolutely no effect on the outcome of the election, include the fact that there was no tampering whatsoever with voting machines. The briefing came as mr. Trump for weeks has cast doubt on the Intelligence Community. They have no idea if its russia or china or somebody. It could be somebody sitting in a bed someplace. Reporter before the meeting, which lasted nearly two hours, he told the New York Times he believed the intense focus on the russian cyberattacks was a political witchhunt by his opponents to undermine his presidency. They got beaten very badly in the election, mr. Trump told the time. They are very embarrassed about it. Vice president elect mike pence was also in the meeting. Were going to take aggressive action in the early days of our new administration to combat cyberattacks and protect the security of the american people. Reporter now, despite his public criticism, mr. Trump also said today, scott, that he has tremendous respect for the work and service done by the men and women of the Intelligence Community. Pelley jan crawford for us tonight. Thank you very much. During the campaign, mr. Trump also said that he would stop illegal immigration by forcing mexico to pay for a wall. But today, it appears mr. Trump expects american taxpayers to pick up the tab. First. Nancy cordes has that. We will build the wall 100 . cheers reporter it was perhaps his most memorable campaign promise, uttered hundreds of times on the trail. And who is going to pay for the wall . Mexico they may not know it yet, but the answer is mexico. Reporter but today, mr. Trump appeared to acknowledge that americans, not mexicans, would likely write the check, claiming, any money spent on building the great wall for sake of speed will be paid back by mexico later. Its the latest campaign reversal for mr. Trump who has also backed off vows to ban muslim immigration, create a Deportation Force because youd be in jail. Reporter . And prosecute hillary clinton. I dont want to hurt them. Theyre good people. I dont want to hurt them. Reporter the wall came up today because g. O. P. Lawmakers are looking at reviving a 2006 law that authorized but never funded a 700mile border barrier. Cost estimates range from hundreds of millions to more than a billion. Indiana republican luke messner. Listen, its big dollars, but if this is a priority for our country, then we should fund it. Reporter on cbs this morning trumps senior adviser, kellyanne conway, insisted theres been no flipflop. And if congress is trying to find different ways to fund this project that can is a top priority of president trump, then they should do that. Reporter it was never totally clear how mr. Trump planned to force mexico to pay for a wall it doesnt want. Its even less clear today, scott, how he could come pel mexico to repay the United States after the wall is already built.
