Shake it off superstar shaken up seeing red after a fan grabs her during a concert. How she managed to go on with the show in style. And good morning, america. Lets get right to the news starting with that scene that is so scary and so sadly familiar these last few months, another attack at an american movie these theater. Police and s. W. A. T. Teams wasting no time descending on the scene. Abcs Steve Osunsami there now and he starts us off. Good morning, steve. Reporter good morning. This is now the second shooting at a Movie Theater in the last two weeks and people who were inside thought they were going to die. Without question, this is making families across the country even more nervous about going to the movies. He pulled out like a hatchet and started attacking his family and then pulled out a gun and we all ran out of the theater. Reporter this is the man who sent sent people running for their live, 29yearold v ichlticente david montano. He stood up wearing a surgical mask, two backpacks and a fake gun. He started hitting people with this hatchet and blasting them with pepper spray. Around 1 13 p. M. The first 911 calls came in. It was a lot of shots. It was coming from the side of the theater. Reporter just minutes later an officer nearby responds. Police say montano is firing a plastic gun that shoots plastic pellets but say it looks and sounds like a semiautomatic politician toll. Officer Jonathan Fritz shoots back but with real bullets. Montano fills the auditorium with pepper spray as terrified people inside the theater run. The police force him out of the theater where a small army is now waiting and firing. He dies in a hail of gunfire. One of the theaters customers wounded in the shoulder by that hatchet says hes thankful no one else was seriously hurt. I would like to thank all of the citizens who gathered around us, helped my daughter when we were pepper sprayed. That kind of gives me a little bit more faith in humanity again. Reporter police have yet to share a motive but underline this is the Second Attack at a Movie Theater this summer and they worry. This is maybe what we call the new normal and we cant just shut down america. We carry on. Reporter police say this man had a history of Mental Illness and given what happened in aurora and lafayette they say this could have been much worse. Families here are thanking police for their quick response. George and lara. He got there so fast. Steve, thanks very much. Well move on to breaking news in the search for that Malaysian Airlines flight that went missing a year and a half ago. Officials this morning say they have recovered more debris that may be from flight 370. As palation Officials Say, a piece of wing washed ashore is from that plane, french officials will not confirm that yet. Abcs david wright is in paris with all the latest. Good morning, david. Reporter good morning, lara. We still dont know if that new debris is actually from flight 370, only one confirmed piece of the plane so far and for the family members understandable frustration at the mixed signals. They have the big answer they need. But still so many questions. On reunion island new reports of wreckage handed over to the authorities here in france. We knew reporter malaysian Officials Say it appears to be a plane window, aluminum foil and some other items. But this is the only confirmed piece of the jigsaw puzzle conclusively identified by investigators as a wing flap from a boeing 777. Theres only one plane of that type unaccounted for in the world. Proof enough for the malaysian prime minister. Debris found on reunion island is, indeed, from mh370. Reporter but sources tell abc news the investigators here have not been able to match a serial number to the part. Raising here its a strong presumption the part is actually from the plane. We still dont know why the plane crashed or where and even though the wing flap washed up on reunion island, the currents could have dragged it an ocean away from the crash site. The real answer to whats happened to this airplane is sitting at the bottom of the ocean. Reporter for those family members waiting so long, more frustration. Im not disappointed. Im disgusted. Reporter even now still not the answers they need. Well, almost the same as the first day last year and the plane is still missing and we still dont know where our loved ones are. Reporter as for that new debris still unconfirmed, the french investigators will be having a strong look at everything hoping that if they get more pieces of the puzzle, they may finally have some answers. George. We certainly hope so. Thanks very much. We turn now to tonights main event, the first president ial debate for the republican, top ten candidates face off in cleveland, the very same arena where one of them will be nominated next july. Abcs tom llamas is there and, tom, ive never seen a debate this early with such high stakes. Reporter thats right, george and, good morning. Usually its lebron who brings the action at this arena but tonight its the republicans and as you mentioned there is so much hype, so many people and so much trump. This morning, republican candidates hard at work preparing for tonights debate, but not the frontrunner, donald trump. A senior advisers telling abc news, trump doesnt rehearse. The billionaire who is still in new york has been lowering expectations. Ive never debated before. Im not a debater. Reporter telling george wednesday he doesnt plan on throwing the first punch. I dont want to attack anybody and, you know, maybe ill be attacked and maybe not. Id rather just discuss the issues. Reporter overnight gma getting a first look at how the candidates are gearing up for the debate. I like to be mentally focused. I take my new phone thanks to the donald and listen to motown. Before a debate i go out to run. A great way to relax. I normally call my mom to get advice. Reporter the lightheart eded attempts. The top ten candidates will fight to break out and fight for time. Only two hours including commercial breaks, thats only about ten minutes per candidate and some may try to draw a difference with trump now dealing with a damaging report. Trump spoke with president bill clinton on the phone about his political inclinations just weeks before he jumped into the race. A sign he may be too up close and personal with the clintons. I wouldnt be surprised if in the course of the debate this conversation about bill clinton and how genuine of a republican or how real authentic a conservative donald trump is, i think it could easily become part of that equation. Reporter now, there are more than ten republican debates and right now 17 candidates, but this debate is important. Youll remember during 2012 so many republicans either skyrocketed or collapsed because of a debate. George. Yeah, one candidate had to drop out off the first debate. To break it down with jon karl starting out with that phone call. Depending who you talk to it was a Courtesy Call or a strategy session. If you listen to the trump people they told me that this that president clinton said trump would have a huge impact on the Republican Party if he were to get involved, that he would be a disrupter, somebody that could have an impact on the entire political system. If you talk to the clinton people they say the 2016 race didnt even come up but, george, this call happened in late may right after hillary announced and just a couple weeks before trump announced. Meantime, you know, i was struck by something the fox moderator said. We dont want to make this into the donald trump show but it is. It is. If their name gets mentioned they get an extra 30 seconds. Every time you mention trumps name he gets an extra minute. Starting from the bottom up, scott walker, 3 million talking about him, ted cruz, about the same, bush, 5 million. Bernie sanders, about the same, Hillary Clinton, 11 million. Look at trumps number, 26 million. He basically has twice as many as Hillary Clinton and jeb bush combined. The other candidates dont want to give him more air time but they all have to be ready. Yes, especially jeb bush who will be standing right next to trump at center stage. Okay, jon karl, thanks very much. Every time they utter his name, another chance. Another 30 seconds. Going to have to come up with a nickname. Moving on now to that monster storm tearing through the pacific ocean. Take a look at this image of it from space taken by astronauts scott kelly at its peak it was the strongest storm of the year, now its headed straight for land. Ginger zee has all the latest. Yeah, the current satellite takes it just east of taiwan, look at that thing, moving only at 12 miles an hour and will target taiwan in the next 24 to 36 hours. Thats the worst of it, the heaviest side is usually the right side so northeast corner, the coast where the storm surge, flash flooding, talking noon tomorrow our time and just after and then itll make into the strait of taiwan and eventually east china but tayie payaipei is what were concerned about and a Tall Building there with neal karlinsky. Being in a 101story Building Made of glass might seem a terrible idea in a sigh fan but they have been to withstand 134mileperhour winds but this one might come in with winds up to 140 Miles Per Hour. The gusts at 140 Miles Per Hour but sustained wind, constant of 100 plus Miles Per Hour, fortunately taipei is on that one side of the mountain so may have a little protection. Im mostly concerned about flash flooding some of the smaller villages at the bottom. This is going to be a big storm and well talk about it for the next 36 hours. Thank you. Turn no to a major Security Breach at the new Orleans Airport where a driver crashed through a fence right onto an active runway. Abcs jim avila has the story. Reporter is this a warning to americas airports . A simple sedan takes out two fences at new Orleans LouisArmstrong International airport. Making it all the way onto an active runway. Down on the taxi muchway there. Do you know who he is . We dont even know who that is. Its a random vehicle.

Then as police approach, the driver almost immediately gunned it again and punched through a second fence, finally arrested just off airport property. Charged with hitandrun and drunk driving. No other airport damage done and no planes even delayed. But just this spring the Associated Press found americas airport perimeters had been breached at least 268 times since 2004. Some of them caught on tape like this driver being chased by police right onto the massive dallas ft. Worth runway.

These runways are supposed to be secure and some airports do have ground sensors but as we saw in new orleans too often all thats between planes and trouble is a chain link fence. Lara thats scary.
