And behind the scenes of the walking dead. Were with the stars of the one of the most popular shows on tv. What it takes to transform a human into a zombie and why one of them bit me. What would you treat this with . With a zombie bite, dont you just chop off the arm . Yeah. We could go from here but aesthetically we should go from here. Hey, good morning. We want to get straight to the breaking news this morning. What looks like a new case of ebola in america announced just moments ago. And the latest victim is a Health Care Worker at that very hospital in dallas who had direct contact with Thomas Eric Duncan before he died. If confirmed, this would be the first time ebola has been transmitted from person to person here in this country. So a very worrying development. Were going to talk to our dr. Rich besser in just a moment, but first for the very latest, lets bring in tom llamas. Good morning to you. Overnight a Dangerous Development in the fight against ebola. A Health Care Worker at texas Presbyterian Hospital testing positive for the deadly virus. This is now the first person to be infected inside of the u. S. We just received a statement from the Texas Department of state health services. They tell us a Health Care Worker at texas health Presbyterian Hospital who provided care for the ebola patient hospitalized there has tested positive for ebola in a preliminary test. Now, this worker cared for Thomas Eric Duncan, the first ebola patient diagnosed in the u. S. We know the worker had a fever starting on friday. Now, samples taken from the latest ebola victim have now been transferred to the cdc in atlanta for further confirmation. Officials are now working to locate anyone who has come in contact with this patient. Were also working to find out if this hospital worker was part of that pool of 48 that came into contact with duncan and was being monitored or if this person was outside that pool which could make this even more dangerous. Dan and paula. Thank you very much, tom. Now, with insight we want to turn now to our dr. Rich besser who recently returned from the ebola hot zone of liberia and is an Infectious Disease expert. Dr. Besser joining us from washington. Good morning, dr. Besser. This casers as we mentioned, has to be confirmed. If it is how big of a net do you cast regarding those affected and who will Health Officials be looking at . Just like with mr. Duncan where they looked at casual contacts and close contacts, you want anyone whos had contact with this individual while they were sick. So you cast a very wide net and then you narrow that down as you really explore what kind of contact they had. Now, this would be the first transmitted case of ebola ever here in the u. S. , so what are the next steps of containment . Well, this is very disturbing if this turns out to be true and theyre going to need to look and see what happened in the hospital to allow this to occur. If it were someone who met him when he first came in the hospital, thats one thing, but part of the care team of the patient while in the hospital, it really throws into the question the cdc recommendations that any hospital can take care of a patient with ebola. They just need an isolation room and certain equipment. I think that it takes a lot more than that. Im much more comfortable seeing these patients in units like the one in nebraska and emory where they train on this. Its not easy to do protective equipment properly. All right, if folks are waking up to this very disconcerting news this morning, dr. Besser, how concerned should we be . You know, if you were someone who was on that health care team, you need to be monitoring your temperature. For the average american, its not putting you directly at risk but it does say that this ebola situation is not over. This is something were going to be dealing with for a long time until the problem is knocked out in africa and we will be seeing more of these cases here in america. All right, dr. Besser, the sample being flown today to atlanta to cdc headquarters and we should have confirmation later this afternoon. Thank you for your time. As the doctor said, this is not over. Dr. Besser, thanks again. We turn now to another developing story this morning. Tension, tear gas and arrests on the streets in the st. Louis area as crowds turn out to protest the Police Shootings of young black men in that area including the now infamous case of the unarmed teenager, Michael Brown, in the city of ferguson. Abcs jeff zeleny is in st. Louis right now. Jeff, most of the protests were peaceful but there were some pockets of trouble. Reporter good morning, dan. Youre right, the protests were passionate but peaceful until early this morning when one small group clashed with police right here. Another sign that racial tensions here are close to boiling over. Overnight, protesters marched on this Convenience Store in st. Louis. Police warned these quiktrip stores could be sites of rogue protests in weekend demonstrations here. Police arrived in full tactical gear. Protesters linked arms to block the stores entrance. Police tried to move the demonstrators away. A producer from our Sister Network fusion said tear gas was launched causing more chaos. This as Michael Browns mother led a prayer vigil only hours earlier before several hundred protesters marched through the streets of nearby ferguson ending at police headquarters. Officers stood their ground even as they were repeatedly taunted. Its what organizers call ferguson october. Thousands descending on downtown st. Louis and nearby ferguson demanding accountability for what they believe is racial injustice. A weekend of peaceful protests include demonstrations like this suddenly spontaneously hundreds of people in the streets closing down traffic. While many protesters traveled here to missouri, most we talked to were like ben centuria, a st. Louis native outraged by two recent shootings of young black men by white officers. How is your city right now . How is st. Louis . Ready to blow up. If youre white you get one kind of justice, if youre black you get another. Reporter the shooting of Michael Brown sparked a National Debate that played out all weekend long across the city. Emotions raw, hope is fleeting. Theres a lot of racism thats come out of this. And i thought it would be for the better but i think its been for the worse. Reporter now there was no looting or violence like we saw two months ago but the arrests overnight suggest that the outrage here is far from over. One local activist told me it was from a rogue group of protesters but this is continuing here as authorities continue to investigate another Police Related shooting. Paula. Jeff zeleny, great reporting from st. Louis this morning. And now to a story breaking overnight and something so many of us do this time of year, a haunted hayride, well, it turned into a frightful scene, a wagon overturning spilling riders to the ground. Some people seriously hurt and abcs tai hernandez joining us in studio with more. Good morning, tai. Good morning. Its a fall tradition right alongside pumpkin picking and hot apple cider, but but there was nothing comforting about this hay ride. Have a report of a Motor Vehicle crash on the hayride. Multiple injuries. Reporter overnight a haunted hayride ended in real panic. 20 to 30 people injured. Hayride lost control went down a hill and rolled. Reporter Officials Say passengers were thrown from the outofcontrol ride. Rescuers rushing 24 victims to area hospitals, 2 of them airlifted with serious injuries. Theres multiple people with broken bones, neck injuries, back injuries. Reporter the county Sheriffs Office says approximately 30 riders were on board the Harvest Hills gauntlet expecting a lighthearted thrill like this promotional video on the website but along the ride of bumps in the night and hand painted haunts, the vehicle missed a sharp turn on the heavily wooded trail. He missed a curb and went into the wood line and it looks like the trailer jackknifed and hit a tree. Reporter Staff Members say those on board were thrown from their seats when tra trailer overturned. When we went down there it was just there were a lot of people just laying around. Reporter this morning hospital officials tell abc news one of those passengers remains in Critical Condition and many others are serious but stable. So if youve ever been on a hayride, you know part of the fun is that there are no seat belts but you can always talk to the driver if you feel theyre going too fast. That could reduce your risk of flying out as these passengers did in this case. Definitely a freak accident. Thank you, tai. Thanks, tai. Now to another strange story. Police releasing video, this video of a man popping out of a new york city subway grate and throwing a smoke bomb into a restaurant. This birz saar incident raising the question how safe is the citys huge subway system from terrorists . Abcs Mara Schiavocampo has been looking into that. Good morning to you. Dan, good morning. New york city has hundreds of miles of subway tunnels. Now there are new concerns about protecting those underground passages after a man was able to get full access. Its one of several Security Breaches in new york in recent months. This morning, the search is under way for this man, captured on Surveillance Video throwing smoke bombs into a crowded new york city restaurant. Watch here as a man in a baseball cap and tshirt suddenly emerges from a subway access hatch in the sidewalk launching two smoke bombs into a cluster of diners at the restaurants outdoor tables. Take a look again. The man disappearing immediately after tossing the smoke bombs. The unsuspecting patrons panic. All of a sudden they told us it was a smoke bomb. Reporter one of them charmed Actress Rose Mcgowan sent this stunned tweet. Someone just threw two red smoke bombs into the restaurant i was eating in. Eyes are burning. Nycwhat. He obviously could have caused somebody to be injured or even potentially killed because of a panic. Reporter these hatches are used as emergency exits from the new york city subway system and police are investigating how this man could have gotten access to these tunnels. The bigger security concern, how the attack could have been launched from the citys tightly guarded transit system. Other breaches have citizens on high alert. Just this summer the Brooklyn Bridge was infiltrated once by two german artists who replaced the American Flag with these white flags. Then in august, a man was arrested for taking photos after climbing to the top of the bridge. Now, thankfully no one was hurt. No arrests have been made. Police say theyre looking for a white male about 20 years old. Really scary that someone was able to get in and then get out in that way. Right, just a prank although it does expose some potential weaknesses. A prank that nobody finds funny this morning. Thanks, mara. Overseas now to the war on isis and what could be an impending humanitarian disaster as the battle for the city of kobani in syria rages on and u. S. Led air strikes are doing little to stop the militants from seizing that town located close to the border with turkey. Alex marquardt has the latest on this fierce fighting. Good morning, alex. Reporter good morning, paula. Thats right. This morning, all eyes on the city of kobani where dozens of u. S. Air strikes have failed to stop the march of isis. American officials now warning that its fall may be imminent. And then over in iraq isis creeping closer and closer to the capital of baghdad fueling criticism of the u. S. Led air campaign. This morning the violence and bloody siege of kobani is raising questions about the effectiveness of the u. S. Led air campaign. This new isis propaganda video showing militants methodically moving in street to street, house to house, advancing in defiance of the around 50 mostly american air strikes against them here in the past week. Already the black flags of isis are flying from the large parts of town they control and american officials have warned that the fall of kobani may be inevitable. Were doing everything we can from the air to try to halt the momentum of isis against that town. That air power is not going to be alone enough to save that city. Reporter there have been more than 400 strikes in iraq and syria since the Campaign Began two months ago. But isis still controls almost all of the vast territory it had seized and has now taken control of most of iraqs Anbar Province on the doorstep to baghdad. Local officials there have desperately called for american Ground Troops to intervene. Despite the lack of clear victories, the Obama Administration says it is succeeding in the longterm goal of degrading isis and preventing it from establishing a safe haven. But that may not be enough for kobani where local Kurdish Forces are desperately begging for u. S. Heavy weapons to push isis back. The United Nations has warned that if isis takes the town, that thousands could be massacred. Dan. This is a dire situation, alex, thank you. For more on this, lets go to washington and abcs chief Global Affairs correspondent martha raddatz. Martha, the u. S. Has been saying that the air campaign is succeeding, but does the potential fall of this city expose the weakness of the campaign . Reporter i think youve seen the weakness of air campaigns throughout history and particularly now in syria and kobani and the pentagon will say quite frankly this is all we can do. You heard the spokesman there say this is what were doing with the air strikes and that will not be enough. Youve heard again and again the military say, it will not be enough throughout iraq and syria. They need those ground forces. The u. S. Has said they will not be u. S. Ground forces, but as you know, dan, there are advisers helping the iraqis but they are not ready to go back and reclaim any of these towns and Anbar Province is truly threatened this morning. And thats right outside of baghdad but just very quickly just to button it up the world then will end up standing by and watching this city fall to isis . The chairman of the joint chiefs of staff told me he fears it will fall. He doesnt believe there are 5,000 people even left in the city, but clearly there will be some atrocities there if this falls. Sad to hear. Much more on this throughout the day here on abc news, and martha, by the way, will have much more on the fight against isis when she hosts this week later and talk about the new case of ebola, the first transmitted in the u. S. If confirmed. All coming up later this morning right here on abc. Weve been talking about ebola all morning but Ron Claiborne has an update on the enterovirus, as well. Thats right. Good morning to you, paula and dan and rachel. Good morning, everyone. We begin with the deadly enterovirus d68 that is sweeping across the country. It has now claimed yet another toddlers life. 21monthold Madeline Reed died friday in detroit. This comes one week after 4yearold ellie waller of new jersey became the First Official fatality directly caused by the virus. The cdc says five others who were infected with entero have died but not clear if the virus was to blame in those cases. Some frightening moments aboard two us Airways Flights in separate incidents on the same day at the same airport. Both had to make Emergency Landings. Oxygen masks deployed in one after an air pressure problem in the cabin. The captain had to make a quick descent from 19,000 to 10,000 feet during the approach and a short time later a regional jet made a safe Emergency Landing also at charlotte due to a hydraulic problem. There were no injuries on either flight. And today is the day that hackers are threatening to release about 100,000 photos from the popular photo sharing app snapchat. Uhoh. The pictures that were supposed to be erased moments after they were sent were apparently stolen by the hackers. The collection of leaked images is like last months scandal in which a hacker posted hundreds of naked images of celebs among them jennifer lawrence. And a florida family had to be rescued off the coast of miami after their boat quickly started taking on water and flipped over in the open water, the open ocean there. A nearby boater noticed the three adults and three children waving and yelling for help. Ron arveev came in close to the stranded boaters and managed to pull them one by one inside of his boat. And were going to move to the delivery of a special delivery of a different kind. A baby delivered in the back of a new york city cab when sara steinhouse, her water broke a week early, she hopped into a cab with her brother, michael, brotherinlaw michael, a fourth year medical student. With the taxi stuck in traffic and baby william couldnt wait any longer. Look at these stunning images. Steinhouse giving birth to a bouncing baby boy from the backseat with uncle michael playing doctor. I dont think i was ever thinking about whether or not i was going to make it to the hospital. My nephew and i share a pretty special bond now. Well done. But both sara and michael say a hospital probably would have been better and this warning to baby william from me, you know, one day youre a newborn, the next thing you know youre 40 years old and won
