At Least 59 Dead, 527 Injured in Las Vegas Massacre
CHRIS CUOMO, CNN ANCHOR: Here is the latest on what we now know as the deadliest mass shooting in modern U.S. history. Fifty- nine people lost their lives at that concert, 527 more injured. And there's a range of those injuries, so many are still fighting for their lives. This monster that was behind this rapid gunfire you hear, the likes of which we never heard in a situation like this -- cops found 42 guns. The hotel room stocked with weapons and ammo. He had ammonium nitrate, which you use as a type of fertilizer that people use to create explosives. He had more weapons back at his house. Sixty-four-year-old on your screen, no criminal past. He cleared gun background checks. The killer's brother says the family is completely dumbstruck. But you know what? The hunt for investigators is going to be who knew something about where this man's head was? And we will stay on that part of the story. But just as important, and even more important are the faces on your screen. We're seeing the vigils across this country. People killed. Special education teacher, nurses, police officers, people who made a decision with their lives to help others, taken out by someone who wanted to help no one. Trauma surgeons right now in the city are caring for gravely wounded. They're comparing the injuries to a war zone. CNN's Stephanie Elam is live at Las Vegas University Medical Center. And, boy, were they overwhelmed. We keep talking about the people who had to step up. Not only were they way beyond capacity, but these types of rounds, these types of numbers, it is amazing what they've had to deal with.</s>STEPHANIE ELAM, CNN CORRESPONDENT: It's amazing the response that happened as well, Chris. When you talk to surgeons like I have here, talking about how they got all hands on deck as quickly as possible, they were here before the patients started arriving. This hospital alone, University Medical Center of Southern Nevada, the only level one trauma center in the state, they received 104 patients. We can tell you they did say they've now treated and released some 40 patients. But we do know that there are two teenagers that are still here. There are 12 people in critical condition here at this hospital. But the response here, they did say that they've never seen anything like this here at this hospital. But at the same time, they felt that the response, that they were able to handle all of it, even triaging some of the patients outside. But at one point, they even had more surgeons on hand ready to go than patients that were ready in the eight operating rooms that they have here. The other response that was great was citizens, people in Las Vegas that turned out even before the sun came up yesterday to donate blood, lines wrapping around the buildings. They've even said so far they have enough blood right now to treat these patients. What they are asking people to do, though, is to remember that in the coming weeks, there may be still more demand. And so, they're asking people, Chris, to remember that and to still be donation worthy in the next couple of weeks here, but a great response from the people in Las Vegas, Chris.</s>CUOMO: Strong point, Stephanie. Just because they're saying they have enough now doesn't mean they're going to have enough going forward. Incredible volume of humanity, dealing with 500 people plus, who knows how many they'll need and what they'll need. Stephanie, thank you very much. All right. So, the president of the United States, he said that when it comes to what happened here in Las Vegas, we are united by grief and pain. Those words are going to apply in a different context when he lands in Puerto Rico today. He is going to find a mass of humanity there that is living in crisis. We're going to take you through where he's going, what he's going to see and what the expectations are. Live report from Puerto Rico, next.
