Definitely one of a kind. The surveillance camera that caught the crime. Did the crooks even know what they had . And the hollywood happy ending. Lupita nyongos stunning oscar dress stolen and now mysteriously returned. Why the thief apparently brought it back and what we could be learning about the value of that dress. Hey, good morning, everybody. March is coming in a little bit like a lion. Take a look at the map. Weve got a storm creeping up on the west coast and in the east another Storm Brewing down south, yet another weekend storm. This one will soon stretch all the way up into the beleaguered northeast. And the nasty weather added to a nightmare for passengers on an American Airlines flight out of dallas overnight. They were stuck collectively at the gate and on the tarmac for roughly nine hours capturing the mood on that plane with their cell phones. Yeah, dipping into the drinks cart, i can see. As they should be. Our reena ninan is following the story for us. Good morning, reena. Hey, paula, dan, good morning. By the time you make it here to the checkin counter, the toughest part of your journey might be perhaps be the security line. Just behind me. But for some American Airlines passengers, they experienced a series of flight delays turning into a travel nightmare they wont soon forget. A nightmare for passengers on American Airlines flight 382. What was supposed to be a short nearly onehour flight from dallas to Oklahoma City turned into an eternity. Delay after delay keeping travelers stuck on the plane nine long hours after the flight was scheduled to take off. Ten hours later it feels great to be home. Its an incredibly stressful day. Dont ever want to do that again. Reporter passengers catching the mood on the plane with their cell phones. It was just up and down. Like we were happy one second because we thought we were leaving then the next second we were just deflated because we were turning back to the gate. Reporter American Airlines tells abc news we apologize for the frustrating experience. Yesterday was a challenging day at dfw due to extreme weather impacting north texas. The safety of our passengers and employees is always our top priority. Delays began because of Winter Weather and plane deicing, but passengers were never held on the actual tarmac for longer than the threehour limit set by the passengers bill of rights. It was an unfortunate event. Were all here, nothing we can do about it. Reporter but then a different law caused yet another delay. The flight crew had to be relieved after working more than the legal eight hours. At times the scene on the plane becoming chaotic. Passengers taking it upon themselves to raid the liquor fridge. It was kind of a mix of comedy and anger as tensions were high. Reporter the good news, though, in 2009 there were 868 domestic flight delays, people stuck on tarmacs more than three hours but since passenger protections put in place that dropped to just 30 last year. So some positive news. I like what that guy said about the mixture of comedy and anger. Probably unwise to add booze into that mix but, reena, thank you. For more on this lets bring in abc news aviation consultant steve ganyard. Steve, technically, and reena mentioned this, the airline didnt violate the passengers bill of rights because the plane wasnt on the actual tarmac for more than three hours, but you say that is really not good enough. Dan, i think theyre being a little too clever by half here. Theyre saying well, we trapped you on this airplane for nine hours but at least we didnt keep you out on the tarmac for three of those nine. So there are questions for american. Why would you board an airplane and keep people on for four and five hours or send an airplane to get deiced and then have it sit there for 90 minutes. Why does it take 90 minutes to do that so i think american is really trying to defend the indefensible here. Now despite the infuriating nature of this experience to the passengers you do want to make a point deicing is of paramount importance, why . Well, sometimes people dont understand why the deicing process is is so important because any time you get ice or frost on a wing, youve changed that wing in a way that could make it so it couldnt be able to fly. Some of the worst aviation mishaps ever in history have been due to icing, so its very, very important for the airplanes to be properly deiced, but in this case the weather had been bad for days in dallas. American, this was not a surprise to american that they should have been better prepared and should have executed better. And they are apologizing this morning. Stand ganyard, thank you for your expertise. And, paula, over to you. Thank you, dan. Now for many what feels like the neverending Winter Weather. A storm developing, one that will bring snow, sleet and freezing rain all that familiar from the rockies all the way to new england and rob is tracking it all. Hi, rob. I can tell you my friends in dallas even are tired of this winter. Theyve had a nasty stretch for the past week. All right, lets talk about where the storm is and how far its going to stretch. Boy, the accidents yesterday, over 400 cancellations in flights, a lot of those were in the Dallas Forth Worth area. I35 coming to a crawl because of just 1 to 2 inches of snow but that in the dallas area is enough. All right, this next storm will clip north texas, weve got Winter Weather advisories and now a winter storm warning posted for st. Louis and a winter storm watch for parts of western new england, freezing rain in oklahoma and this blossoms as it gets across the ohio river, st. Louis towards cleveland across through pittsburgh and then the rain snow line dancing over the new york city area and see greater amounts across further to the north. Could see a foot in places like st. Louis and western mass too. Thats a quick check on whats going on. Well talk more about the bitter cold and a california storm, as well, a little later in the broadcast. But, rob, this is the first day of meteorological spring, is that right . Youre getting ahead of yourself. Its tomorrow, but i like the optimism. Never correct me on the weather, rob. I know youre a meteorologist and everything. All right. Excellent. Thank you. So well talk more about that coming up, thank you. Were going to move on now to what appears to be a vicious political assassination making headlines across the planet this morning. A popular and outspoken critic of russian president Vladimir Putin shot in the back right out in the open just blocks from the kremlin, and abcs chief Foreign Correspondent terry moran is on the story. Terry, good morning to you. Reporter good morning, dan. Moscow is in shock today and a sharp chill of fear has ripped across russia. One of Vladimir Putins fiercest critics, as you say gunned down in broad daylight. Four bullets in the back in the very shadow of the kremlin. This morning in moscow, flowers on a bridge usually filled with pedestrians and tourists mark the spot of the brazen killing. The scene last night was eerie, incredible, the body of boris nemtsov, a veteran russian politician, longtime putin foe, lay on the ground, four bullets in his back. The killing coming one day before nemtsov was going to lead a march of peace against putins war in ukraine. A spokesman for the russian interior says he was walking with a female acquaintance when assassins leapt from a white car and opened fire. Take a look at this surveillance video. Thats the getaway car reportedly heading toward the crime scene, a black sedan close behind. Vladimir putin says he is personally taking charge of the investigation into nemtsovs killing. Kremlin spokes p pern dmitry pesko saying in a statement, putin believe ss the cruel murder has every sign of a contract killing. Nemtsov was a former deputy minister in the 1990s once described a possible president himself but putin outmaneuvered him and nemtsov became a harsh critic organizing protests and exposing massive high level corruption especially during the Winter Olympics in sochi describing putin to abc news brian ross. Do you worry what will happen to you . Everybody against him must be very careful. I think that we must replace him because he did everything against the interests on my country. Reporter alarming times, reminiscent of the cold war as a recent gallup poll reveals that americans now view russia and putin as americas greatest enemy. Nemtsovs friends and supporters gathering now in moscow at the scene there. They say sundays peace march will go on and they also say nemtsov was working on another major expose when he was killed. He had evidence, he claimed, of the use of Russian Troops in the war in ukraine. Paula. A lot more questions than answers this morning, terry moran from london, thank you. And were getting a Surprising New look at the isis executioner known as jihadi john. Here he is unmasked wearing a Pittsburgh Pirates cap while attending a british university. The team saying theyre sickened by that image of the worlds most wanted killer, and chief investigative correspondent brian ross has the very latest from london this morning on the worldwide manhunt to find him. Brian. Reporter well, good morning, paula. The man and the family have now fled their home. The family now in hiding as the world asks how could their College Educated son, mohammed emwazi, turn into a brutal killer for isis . This is what he looks like without his mask and his knife. A London College photo on the front pages of british newspapers this morning showing a young man with a sneer and unaccountably a Pittsburgh Pirates baseball cap. How emwazi went from this to this is the puzzle authorities and friends are trying to answer this morning. Well begin to slaughter your people on your streets. Reporter one friend told the bbc emwazi was happy with his life after he graduated from university. We never realized that he will go to the jihadi. Reporter but one of his emwazis Elementary School teachers told the bbc, he was put into anger management therapy at the age of 11 because he was getting into too many fights. Wed find that hed get very angry and worked up, and it would take him a long time to calm himself down. Reporter emwazi came of age in london at a time when radical islamists were urging young men to join the jihad against the u. S. And britain. Most prominent was the activist emgem choudhury who we went to find outside the biggest mosque friday. He said he did not know emwazi but called him a muslim brother whose brutal acts he refused to condemn. Reporter so as of now you dont want to condemn him. I want to condemn. I want to condemn you guys for being the tongue of the biggest terrorists in the world of the americans and your allies the british. Reporter the other question being asked here this morning is how emwazi was able to slip out of the country and join isis even though he was under surveillance by British Security services. This morning, the british Prime Minister is saying essentially there are just too many young men being watched to keep a tight look on all of them. Paula. That number in the thousands, brian ross, thank you. Tomorrow you dont want to miss our martha raddatzs live interview with secretary of state john kerry. Again, thats tomorrow on abcs this week. So striking to see that cleric refusing to condemn the actions of jihadi john. Startling, shocking. I think we all gasped. Hes a man whos made many controversial comments in the past. A lot of other news overnight. And for that, as always we check the Morning Headlines with dr. Ron claiborne. Good morning, sir. Good morning to you, dan and paula, sara, robert. Good morning, everyone. We begin with the soaring price of gas. Prices below 2 now in the rear view mirror. This morning the National Average is 2. 38, 10 cents higher than just a week ago and now no state in the country has pump prices below 2 a gallon. In los angeles, prices are up nearly 20 cents. They went up in one day and gas buddy expects them to keep climbing. Theyre still more than a dollar less than they were this time last year. And president obama signed a late night lastminute stopgap bill passed by congress to extend funding to the department of Homeland Security for a week. The measure prevented the departments money from being cut off at midnight. A threeweek extension failed to pass the house because republicans, some republicans want to repeal the president s executive action on immigration attached to Homeland Security spending. Democrats want to pass a standalone full year funding bill. And it looks like this years flu vaccine is even less effective than previously reported. Just 18 , in fact, against the dominant strain of this years flu, thats a drop from 23 Protection Level estimated for the flu shot earlier this season and for children it was even worse. The cdc says the nasal spray version may not offer any protection for young people at all. And take a look at this video from wisconsin coming up. An suv youre going to see traveling on an interstate highway when the driver loses control, runs off the road there, rolls over five times breaking into pieces, a huge chunk. Three passengers, including a 5yearold boy, were ejected from that vehicle, but no one was killed. Investigators say the passengers were not wearing their seat belts. They are surprised that anyone survived. Thats a miracle. That is amazing. Also, caught on camera, a ohio state trooper leaping over the guardrail before a semi truck slams into his cruiser. The officer was not hurt. The trooper was trying to help a stranded motorist who ran into car trouble. No word on whether Police Caught up with that speeding rig. And finally, a regal musical sendoff to outgoing attorney general eric holder. At the justice department, aretha franklin, the legendary queen of soul singing holders praises quite literally. A hero yes he is hes a champion hes a warrior yes he is holder was brought to tears or apparently brought to tears during and after the performance. There he is, tearing up or something. Got something in his eye. Hes set to leave office next month we dont know, dan. Allegedly. Successor loretta lynch. President obama teared up a little bit during the ceremony, as well, emotional all around. I think theyre very close friends. Ron, thank you. Now to the historic royal visit to the far east. Prince william touring the tsunami zone in japan and off to china tomorrow and that is where we find abcs bob woodruff this morning in beijing with the latest on this story. Reporter its a day that began with fun for william, the duke of cambridge, first at this anchor chair in tokyo. Then at the studio where japans most loved drama is produced. He got the chance to mix with the actors and play the role of the warlord with a helmet and a samurai sword. Much of his trip is to promote british innovation in japan so like launching a ship with a bottle of champagne, he smashed the barrel filled with saiki, japans famous booze. With him is the ceo of aston martin, so william gunned the engine, one of his most favorite cars, and you may remember he and kate borrowed his fathers aston martin to drive away from their wedding. But the more emotional visit was with japans Prime Minister shinzo abe, to fukushima where they are helping children to smile again since the deadly tsunami ripped through their towns and villages four years ago. A reminder that it was 20 years ago prince williams mother diana came to comfort the victims of the kobi earthquake. Well, i think it would have been impossible for william to go to japan and not to make mention of the tsunami or visit the sites devastated by the tsunami. It was such an enormous natural disaster. Reporter while william is in asia, prince harry is retiring later this year from the military off two tours in afghanistan. Harrys next chapter, his principal focus helping the Wounded Warrior leaving time for the peoples prince to devote time to his other passion, africa. As for william, hell be leaving japan tomorrow and heading here to beijing and then shanghai and finally the Southern Province of yunnan where he will be talking about illegal trade of elephant ivory tusks. Now, interestingly, a couple of days ago the Chinese Government actually banned that kind of trade here for a year, apparently he has some influence. Paula. Yes, he does. An important trip for the prince. Thanks, bob. And this morning we are remembering a beloved actor who became an enduring fixture in pop culture. Leonard nimoy, who starred as emotionless pointyeared vulcan spock on star trek has passed away. Chris connelly with a look back at his remarkable career and the tributes that are pouring in. Reporter words from william shatner, i loved him like a brother. We will all miss his humor, his talent and his capacity to love. The tweets and tributes coming from all around the world, multiple generations of colleagues, ardent fans and those he inspired on screen and in space all honoring leonard nimoy. I see no reason for answers to be couched in riddles. Reporter star treks pointyeared vulcan, mr. Spock. Second in command on the starship enterprise. Nimoy starred as spock through three primetime seasons back in the 1960s. In a decade of emotion and upheaval, a compelling figure of pure reason. A most illogical reaction. Reporter he returned to the character in a series of star trek feature films, 1982s the wrath of khan would feature a tearful tribute from captain kirk. Of all the souls i have encountered in my travel, his was the most human. Reporter he directed the hugely successful comedy three men and a baby. Good night sweet heart reporter he wrote books of poetry, took photograph, even sang fearlessly. Bill bow baggins reporter in 2007 he met president obama, a spock fan, who recalled on friday greeting nimoy with the vulcan salute and spocks words live long and prosper, the same fa
