[Berman:] The breaking news this morning, investigators looking at Tuesday night's train derailment in Philadelphia now focused on excessive speed as the cause. Officials say the train hit that tight curve on Philadelphia's north side at 106 miles per hour. That is more than twice the posted speed allowed there. The death toll from the crash now stands at seven. More than 200 people were injured and eight of them this morning still in critical condition. We have news this morning from Nepal hit by so much devastation over the last few weeks, at least two major earthquakes. This morning, a desperate search by foot and by air is finding no sign of a missing U.S. military helicopter. The crew was helping with relief efforts when it lost contact with the ground. Six U.S. Marines and two service members from Nepal were on board. We want to bring in CNN's Will Ripley, who is live from the base of operations for the search. He is in Kathmandu. Good morning, Will.
[Will Ripley, Cnn Correspondent:] John, behind me an Indian helicopter is preparing to take off and head back into the search zone, but as the hours pass with no visual sign of the U.S. Marine helicopter, they are now going to be relying heavily on the ground search, which is happening right now. There are 400 Nepalese soldiers that are hiking through very difficult terrain in the Himalayans. They are also on boats scouring rivers and mountains as they try to locate any sign of this helicopter carrying six Marines and two Nepalese soldiers. It has been missing with no visual trace and no radio communications from the crew as well. Everybody out here is trying to remain positive, but it is growing increasingly difficult. In just a few minutes from now, we are expecting the Nepali prime minister to come to the area. One of the things that we would like to ask him about in addition to the search for the missing helicopter is much of the bureaucracy that has delayed relief and assistance in getting to people here. There have been a lot of complaints from the Red Cross and other NGOs that because of bureaucratic difficulties with the Nepali government, assistance, food, water, medicines, supplies and personnel is not getting to the tens of thousands of people who are desperately in need right now John.
[Berman:] They so badly need that assistance. Will Ripley on the ground for us in Kathmandu, thanks so much. A U.S. citizen among at least 14 people killed in a terrifying hotel attack in Kabul. Three gunmen stormed the Park Palace Guest House Hotel Wednesday night trapping more than 50 people inside. A five-hour standoff after Afghan Special Forces killed all three attackers. In just the last few hours, the Taliban has claimed responsibility for this attack. The identities of the victims not yet released. A senior Secret Service agent has been implicated in the drunk driving incident at the White House is retiring. Officials say Marc Connolly, the number two agent on President Obama's protective detail is leaving the agency. That news comes just as an inspector general report on the incident is being released. The report says Connolly and a second agent, George Oglvy had been drinking and allegedly drove through a secured area outside the White House disrupting an active bomb investigation. Oglvy remains on administrative leave. I want to take a look at what is coming up on "NEW DAY." Chris Cuomo is on the ground at the crash scene in Philadelphia. Good morning, Chris.
[Chris Cuomo, Cnn Anchor, "new Day":] John, three big points of focus for us here this morning. First is the idea of speed being, what was the catalyst for the crash? Investigators are going very slowly on it. The mayor here, Michael Nutter, was getting out in front of it talking about the engineer and what investigators believe they know early on about the speed. Largely in part from that surveillance video that CNN had this morning, but also from the black box. If the train was going so fast into the curve, which seems probable from common sense of how terribly destroyed the cars were. What does that mean? And more importantly for investigators, why did that happen? Is it human error or systems? You have the issue of the unaccounted for. It sounds suspicious. Investigators tell us it is not about people needing to be located at the crash scene, but the travel on trains, mismatched tickets. People who did not take the train or people gotten on and not presented tickets at the station. Whatever the reason, there are still people unaccounted. We will cover that. And there is this bigger issue, John, which is even if this train crashed because of human error. That doesn't mean it had to happen. There are safety systems in place that are not. There's infrastructure that other countries have that the United States does not, despite the money that gets dumped in Amtrak and rail system. Why? It matters. Even if this is just about the engineer, John, it matters. I would be remiss if not to mention the small window of joy I had in my day yesterday. Watching celebrity "Jeopardy" and seeing a man I have known for 15 years show the rest of the world what I have known so long. His shirt and tie decision today aside, John Berman, owning celebrity "Jeopardy." A proud moment for those of us who know you John.
[Berman:] Thank you very much, Chris. I appreciate it. Great work down there in Philadelphia.
[Cuomo:] Right here.
[Berman:] We have new information this morning about the deadly Amtrak derailment. Why investigators say they knew from the start that this train must have been speeding.
