Investigation Continues into Possible Motive of Las Vegas Shooter
WHITFIELD: In just about an hour from now Vice President Mike Pence is expected to alive in Las Vegas. He'll be delivering remarks at a unity prayer walk for victims and their loved ones. Meanwhile we're learning new details about the investigation. We're learning it was an alarm from a room down the hall from the shooter that brought a security guard up to the 32nd floor. Police say they don't what plans the gunman might have had for several pounds of explosives and ammunition found in his car. And investigators are also saying the shooter brought his guns and ammunition up to the room over the course of several days. I want to bring in CNN's Scott McLean who is following the investigation from Vegas. So Scott, are police saying anything more about the possibility of the gunman may have had some sort of help?</s>SCOTT MCLEAN: Well, Fredricka, they say it's hard to imagine him not having any help. What they are confident of is the fact there was no one in the room with Stephen Paddock at the time of the shooting or before the shooting. What they cannot yet say for sure, though, is whether or not he had any help or at the very least whether there's someone out there who had advance knowledge of this attack that was coming. They say they have combed through, quote, "voluminous amounts" of video from inside and outside the Mandalay Bay hotel. And so far they can't find anything on that video or any person on that video that matches the description or actions of someone who might be an accomplice, though they say that they will leave no stone unturned. Listen.</s>UNDERSHERIFF KEVIN MCMAHILL, LAS VEGAS METROPOLITAN POLICE: We're combing over this man's entire life from birth to death to try to find out. It's hard to believe that one individual planned this attack and executed it without anybody else knowing anything about it.</s>MCLEAN: And we also know investigators continue to question Stephen Paddock's the former girlfriend Marilou Danley, she was in the Philippines at the time of the attack. She's back in the United States now being questioned. We are told she is being cooperative, though her lawyer made quite clear that she will not be making a public statement to the media any time soon. And one other thing to mention, Fredricka, and that's just that we know that Vice President Mike Pence, he will be in Las Vegas early this afternoon to speak at the unity prayer walk early this afternoon, of course, as follows the president's visit here on Wednesday to visit some of those victims. And at latest count we know there were 88 victims still recovering in hospitals, 37 of them still in critical condition. And then, Scott, you're in front of Mandalay Bay. What kind of activity is happening there? Have they opened it? Is there still investigation type of activity around it?</s>MCLEAN: So I actually went inside the building. It's connected to another hotel called the Four Seasons. And we were able to go in with no problem. Drive straight up to the door, go inside. There was no metal detectors. There was nothing to put a bag through, though I didn't have a bag, to be honest. But the hotels, we're being told, and casinos are putting in more un- uniformed security, or plain clothes security. And so that may have been true. But we were able to get up to the room quite easily and get actually a similar vantage point so one that the shooter may have had just from a couple floors higher and a couple floors over. I also spoke to a security expert a couple days ago, Fredricka, who said he cannot think of anything that this hotel could have done to possibly prevent it. He says, look, if you leave your "do not disturb" sign on the door, it's not uncommon. If it you bring in a lot of baggage, people move and sometimes they stay in hotels in between. That's really not uncommon. So he can't, at least, figure out anything that Mandalay Bay could have done to prevent this. But as to your question, things seem to be relatively normal here in Las Vegas, at least in this part. Certainly a big change from what we saw earlier in the week when you couldn't get anywhere close to that hotel.</s>WHITFIELD: All right, Scott McLean in Las Vegas, thank you so much. So in the wake of the Las Vegas massacre, there has been no shortage of high profile people calling for more gun control. One of them is retired NAFTA astronaut Mark Kelly, husband of former Congresswoman Gabrielle Giffords. She survived a mass shooting in 2011 after being shot in the head during an event in Arizona. Mark Kelly had this to say to our Ana Cabrera.</s>MARK KELLY, RETIRED NASA ASTRONAUTS: If we had an airplane that crashed that kills hundreds of Americans, the next day we would talk about aviation safety. If we had a nuclear power plant accident where people died, we could talk about nuclear safety. So why is it with this issue that they always say now is not the time?</s>WHITFIELD: Be sure to check out Ana's full interview with Mark Kelly in the next hour. Still ahead this hour, in the crosshairs, hurricane Nate gets closer to the U.S. gulf coast and is expected to be a category two storm when it makes landfall. Another update, next.
