Last night, what a night at Madison Square garden. So many stars coming together for the victims of sandy. Theres Paul Mccartney playing with nirvana. Well have a lot more of the amazing show right there. Hello to robin at home. Great to have amy robach here. And rachel smith is in for lara today. And we have some chilling, new details about the gunman behind that horrifying shooting at the oregon mall. His exgirlfriend is now speaking out, saying his behavior changed dramatically the week before the shooting. We have video we couldnt stop watching. Here is why. 10monthold babies learning to swim, obviously, before they can walk. We sent our correspondent, lama hasan, to learn the secrets of the pool. Blissful and wonderful. And love listening to this right here. Music can mean only one thing. Jerry seinfeld is here this morning. But right now, lets get to the news. The chopper went down at north island air station as whats being described as a routine training session. All four crew members onboard did survive the crash. They were rushed to various local hospitals, though. The extent of their injuries remains unclear at this hour. Were not sure what caused the crash. We will have more details as they become available. Also this morning, a major escalation in the bloody civil war in syria, that could now raise the likelihood of the u. S. Getting involved. For the first time, dictator assads forces appear to have fired scud missiles at rebel fighters, missiles that could then be used to carry chemical weapons. It is considered a sign that assad is growing ever more desperate. President obama has said that any use of chemical weapons would prompt a u. S. Response. And in money news, the rockbottom Interest Rates that have pushed mortgages to record lows will not be going up anytime soon. In a historymaking move, ben bernanke said Interest Rates will be tied to the jobless rate. He wants the Interest Rates to stay at the lows until unemployment drops below 6. 5 . Which he says could take some three years. And a dire warning about a water crisis in the west. A federal report out today warns the Colorado River is drying up. And within 50 years, will no longer be able to supply water to seven western states. The report suggests dramatic solutions, including towing icebergs from alaska. Critics call the report flawed. Say the warning is exaggerated. And if youve ever been furious at the tv ads that sound far louder than the show youre actually watching, your ears will now be getting a break. A new law called the c. A. L. M. Act goes into effect. It requires commercials to be the same volume as the programs they sponsor. Hear, hear, hear. You do not have to take cover when we go to break. In houston, meanwhile, a thief got the shock of his life. He was trying to steal copper wires from a church, when he sparked what looked like a small explosion here. So powerful, his bolt cutters became welded to the wires. He got away. And we can only hope, learned a lesson in the process. And this ones for you, george. As washington man, the gridlock, at least congress doesnt look like this. Take a look. Nothing gets george like a Good Parliament stepto. Members of the Ukrainian Parliament couldnt decide who they wanted their next chairman to be. So, of course, this is actually, perhaps, in the bylaws. You fight it out. Usually, thats taiwan. It is more exciting than a thumb war. One guy, yes. It did look like he was trying to crowd surf. Weve obviously seen chairs thrown. But not today. Perhaps progress, if only incremental. Boy. Lets hope it doesnt come to that in washington. We have a different story here, though. We have some chilling, new details about the gunman who went on a shooting spree at an oregon mall earlier this week. We are learning more about the shooter from his exgirlfriend. Abcs Neal Karlinsky is in portland, oregon, with the very latest on this. Neal, good morning. Reporter amy, good morning. Thats right. We now know a lot more about the shooter this morning. We know who he is. We know that, according to friends, he seemed to be very troubled recently. But still, what no one understands is what set him off. This morning, as detectives continue to dig into his background, friends of accused shooter Jacob Roberts paint a portrait of a 22yearold happygolucky guy, who suddenly turned dark. I think something in his mind clicked. And it messed with his thinking. And he just wasnt himself anymore. Reporter his friend says something seemed to have happened over the last few weeks. But no one knew what the problem was. And his exgirlfriend, hannah sansburn tells abc news, he quit his job and sold all of his belongings, saying he was leaving portland this weekend and moving to hawaii. This is the last thing i expected. Especially from him. He was just too sweet. Never mean to anybody. Ever. Everybody loved him. Reporter police have no motive, but they also have no doubt. They say roberts carried out his shooting spree alone, with a stolen assault rifle. Among the dead, 54yearold hospice nurse, cindy ann yuille, who was christmas shopping. This woman a complete stranger, stayed with her and performed cpr. She died with dignity. And she did not die alone. Reporter 45yearold steven forsyth, a father of two, was also killed. But 15yearold Kristina Shevchenko was shot in the chest and survived. Amazingly, her second brush with death in less than a year, after being injured in a headon car crash in august. Its clear to me, shes a very brave young woman. Reporter that lucky young lady is listed in serious condition right now. She is expected to recover. Just remarkable this whole thing wasnt so much worse. Meanwhile, back here at the mall, shop owners are beginning to wonder when they can reopen, during this critical time of year for them. George . Okay, neal, thanks very much. Lets get the latest, now, on that fiscal cliff. Just 19 days before everyones taxes go up. Every federal program is cut. And theres no signs of any progress from president obama and House Speaker john boehner, which is raising the tension on capitol hill. Abcs Jonathan Karl is there. And both sides are giving up hope of solving this by christmas. Reporter thats right. In fact, Speaker Boehner and Republican Leaders have warned rank and file republicans that they should be prepared to be here in washington, through christmas, and until the new year. The two sides dont even agree on whats Holding Everything up. The white house says that everything could be resolved quickly if republicans just agreed to raise tax rates on the wealthy. Republicans say whats really the problem here is the white house wont get serious about spending cuts. Everyone waiting on those two men. Meanwhile, one of the side casualties may be that funding for the victims of Hurricane Sandy. Reporter thats right. I do not think that Hurricane Sandy funding, the 60 billion request from the white house, will get done while theres an impasse here. Republicans are already blocking at the cost. They point out, george, that 60 billion, that represents almost everything you would raise next year by increasing those tax rates on the top 2 . And they also point out that fema still has about 5 billion in its Disaster Relief fund, enough to go through march. Okay, jon karl on capitol hill. Thank you very much. Now, to the proposed government crackdown on one of the most deadly hazards on the road, wrongway driving. The ntsb offering measures to keep dangerous drivers off the road. Abcs jim avila has the story. Reporter it is a frightening sight with tragic consequences, the wrongway driver. Its a limited access highway. Reporter this crash just happening wednesday in pennsylvania, killing 27yearold tiffany allcore. We had a fatality. Someone going the highway in the wrong direction. Reporter nearly 400 people die each year from wrongway driving. Most from headon, highspeed accidents. In fact, 22 of wrongway crashes are fatal, compared to less than 1 of all other crashes. And theyre completely preventable. Reporter thats why the National Transportation safety board Just Launched a nation wide crackdown. Zeroing in on those responsible. 15 involve drivers over 70 years old. But the real danger is alcohol. 60 of wrongway accidents are caused by drunk drivers. Nearly 10 by repeat offenders, which is why the ntsb is recommending that all 50 states require this ignition lock on all cars for anyone con verdicted of dui. What happens . The car will not start. Reporter the ntsb is pushing Car Manufacturers to fast track new technology, installing sensors in all cars to determine if any driver is sober before allowing ignition. You wont be allowed to get behind the wheel and use your car as a lethal weapon. Reporter the ntsb also recommends lowering and making bigger wrong way signs. And changing interchange design, by eliminated last entrances. And parallel entrances and exits. And all in an effort to avoid tragedies for a wrongway driver like this one in pennsylvania. For good morning america, jim avila, abc news, washington. We have the latest, now, on john mcafee. Back in the u. S. Now after more than a month on the run in Central America. The Software Pioneer is still wanted for questioning in the murder of an american citizen in belize. But he is free for now. And abcs matt gutman talked to him when he landed in miami. Reporter we found john mcafee, withered from the fiveweeklong odyssey. This morning is the first time in well over a month that hes not waking up in a Central American jungle or in a lockup for Central American migrants. I had no choice. They put me on an airplane. I am here. Reporter overnight, john mcafees monthlong International Run from police in Central America ended with a flight to miami. As dozens of media waited, federal authorities spirited the 67yearold off a plane and into this van. Then, he hopped in a cab, to this miami beach hotel, where he sat down exclusively with abc news. I have clothes and shoes. All of my assets and money is in belizean banks. Reporter but this morning, he says hes broke. Just hours earlier, Guatemalan Police forced him aboard a u. S. Bound flight. Going to america. Miami. Reporter and in the dead of night, a stranger delivered this stack of cash. Very nice. In fact, i thought that it has to be counterfeit. Reporter mcafee left behind his entire fortune, including his beachfront compound, after the november 10th murder of his neighbor, greg faull, in belize. Police there say he isnt a suspect. Police say they wanted to question him. But he disguised himself and fled. Eventually turning up in guatemala december 3rd. There, just a day later, he was detained for entering illegally. Suddenly, he fell ill. Leading to this surreal scene with reporters chasing him in his ambulance, and right into the emergency room. He now says, it was all a ruse. What about your illness . What about my illness . Reporter was that part of the deception . Of course. It kept me from going back to belize. Reporter now, back in the u. S. This morning, hes answering critics who say it was all a publicity stunt. Whats the best story in millionaire madman on the run . Why . You paid attention to the story. Reporter because you acted like a madman. I did. And it worked. Reporter now, mcafee says that he doesnt know where he will go or how he will support himself. In the immediate future, his goal is to bring his two girlfriends from guatemala to the United States. They are 20 years old and 17 years old. Amy . Wow. Okay. Matt gutman, thank you very much. For more, lets bring in dan abrams. And, dan, mcafee is back in the u. S. , legally. Is that the best place for him . This is a win for mcafee. You had the authorities in belize who wanted him sent there. Theyve been looking for him for weeks. He ends up in guatemala. And the guatemalan courts say you have to be sent back to the u. S. As long as theres no outstanding beefs that the u. S. Has with him, this is an absolute win for him. The u. S. Does have an extradition treaty with belize. But mcafee is not being called a suspect in this case. Does it change anything that the alleged victim is also a u. S. Citizen . It means that the u. S. Will be more interested in ensuring whatever outcome it is that they want, but thats unclear. What is the outcome . As you point out, not only has he not been charged. Hes not been named a suspect. So, at this point, theres a guy in the u. S. , who belize would like to talk to. Thats it. Thats not an enormous legal hurdle. Obstacles to getting his two girlfriends a visa into the United States . Hes concerned about that. Yeah, im sure he is concerned about it. I cant believe that the u. S. Will look favorably on it. They will probably get exactly the same treatment that anyone else in that country would get. But one heck of a story. It certainly is. Dan abrams, thanks for weighing in. We appreciate it. And what a magical moment last night here in manhattan. Rock n roll royalty. Bruce springsteen, jon bon jovi, Paul Mccartney, the rolling stones. Just a few of the stars that came together to raise money for Hurricane Sandy. That is just the beginning. This is a hall of fame turnout. And the who. And chris martin from coldplay. Even the musicians themselves were buzzing backstage about the talent assembled. Rock n roll greats from across the pond. And some homegrown talent, as well. My city of ruin come on, rise up reporter it began fittingly, with bruce springsteen, singing once again about loss, longing and hope, along jerseys battered shore. New york concrete jungle where dreams are made of reporter more than five hours later, it ended with alicia keys, and a stage full of first responders. In a night that combined music of the east. And west. And kanye. We made it through the hurricane live and let die reporter at 1 00 a. M. , 70yearold sir Paul Mccartney was tearing it up.

Baby, we were born to run reporter the concert has already earned some 35 million before the first note was played. Countless millions sure to come in later. Great music for a great cause.
