Hello hello, its a Korean High School student . Why this rendition of adeles smash hit going viral on youtube have many asking, is she better than the original . First the nightline 5. When i act if i do this or if i do this im totally in control. I dont have pba. But if youre someone with pseudo bulbar affect you dont always get to choose. Uncontrollable outbursts of crying or laughing in people with certain neurologic conditions. Pba is treatable. Ask your doctor or pbafacts. Com. Number one in just 60 good evening. We begin tonight with a story about murder, criminal gangs and turtles. The sandy setting for this violent conflict, costa rica, where poachers with alleged links to local drug gangs or the prowl for precious good. My nightline coanchor dan harris found out why they want those turtle eggs while others risk everything to stop them. Reporter its the middle of night. Lightning, another reassuring sign. Were in the back of a Police Pickup heading into one of the most dangerous beaches in central america. You can tell its raining really hard. Reporter after an hourlong downpour, the rain clears. Whoa look at that reporter we find what we came here for. Look at the size of her. Reporter were here to witness a treacherous game of finders keepers. You know for sure that there are poach others this beach right now . Yeah, poachers. Reporter conservationist eric alguera ricking his life to protect these rare beasts. We may have a lot of eyes on us right now . For sure, for sure. Reporter poachers and conservationists are racing to claim the eggs from these animals, the leatherback turtle. At up to 2,000 pounds the largest turtles on earth. You can see the eggs coming out. Pretty cool. Its filling up fast. Wow. Look at that. This gives you a sense what was a cat and mouse game this is. These are discarded eggs from poachers, they throw away the unfertilized eggs. You can tell this is a nest the poachers have hit. Reporter these prehistoric giants have been coming to the shores of this beach in costa rica to make their nests since before humans walked the earth. But now they are caught in the middle of a war, a war in which people are willing to kill. Turtle eggs and drug dealing go hand in hand. Reporter this is vanessa lazano. Two years ago her friend jira, a young conservationist, was brutally murdered on the beach, provoking an International Outcry and widespread protests. Jiro vive became a battle cry for conservationists around the world. She was among the first to patrol to save turtle eggs, a mentor to jiro, who was 26. The two off then found themselves in the crosshairs of poachers with links to local drug gangs. Once a month there was a shooting. For me it was normal. Youre out there trying to protect turtles and people are shooting at you . Yes. Chasing you with machetes . Yes. Reporter for the First Time Since the murder conservationists are trying to take this beach back with the help of the local cops who search anyone they find out here for weapons and eggs. This is a costa rica tourists rarely see. Were in one of the most dangerous cities in costa rica, has the highest crime rate. That bar had eggs, that one did not. Reporter with the help of our translator we find eggs for sale openly in local bars. This is a big business in costa rica. Turtle eggs are considered a delicacy. Even an afphrodisiaaphrodisiac. Like viagra . Good, good, viagra. Reporter sellers claim these particular eggs are legal eggs but signs of the violent potential of the illegal turtle trade are everywhere. Watch as this man, who had directed us to one of the local egg sellers, tells us it could have gotten him killed. Vanessa remembers the first time she walked this beach with her murdered friend jiro, who she says she brought along for extra protection. Lets see if you can handle the beach, because its going to be different. Hes like, im used to people threatening me, im used to this. Im like, okay. We went out and the first shooting, we came back, he told me, whoa, this is different, but i liked it. Reporter together they brave the threats, saving as many eggs as they could and bringing them to a safe place where the babies could hatch and make it to the sea. Some people who knew him say jiro did not play by the rule of the beach whoever gets to the nest first gets the eggs. They say this may have led to his murder. It was an incredibly brutal murder. She found his body in the sand the next day. Hed been beaten, stripped naked, and then dragged through the sand by a vehicle. He suffocated. I think its not fair to take the life of someone so young. So passionate. The government i blame. The lack of police force helping us. I blame myself. Reporter seven men, some with alleged connections to drug gangs, were arrested. But then acquitted because of mishandled evidence. You knew jiro, you grew up with jiro . Reporter eric alguera says he is here despite the danger to honor his old friend jiro. Its a busy night on the beach, we have four more turtles. They down this way and then this one who is massive. Ive taken my microphone off so we can get a sense what was she sounds like. Turtle breath. Its amazing to be this close to a creature that only comes to land once a year. She could be over 100 years old. Reporter those flippers land hard. By the end of the night, eric has found 13 turtles and relevance cued more than 1,000 eggs. But he has no idea how many nests the poachers got to first. We wanted to meet some of these poachers so eric directed us to these young men. They immediately deny any involvement. Youre saying that like a lot of people come by and take eggs but they dont. Ah. Yeah. Reporter but they do agree to show us how its done by other people. What hes saying is that they put this up when theres a turtle so that when the police pass by this road they cant see that theyre stealing the turtle eggs. Oh. They know an awful lot about this for people who never poach eggs. Yes. Reporter back at their shanty they show me pictures of them posing with their illegal bounty, although they insist theyre giving the eggs to environmentalists. These are some pictures of them saving eggs. This is right here in this house . What makes this complicated is these kids are immensely likeable. And they dont have any other opportunities. So you can see why they do what they do. Bottom line though is it hurts the turtles. Reporter but the environmentalists here dont consider young men like these to be the real threat. Instead they say its the wellorganized gangs, the type of men who are accused of killing jiro mora sandoval. Meanwhile the turtles remain unaware of the turmoil that surrounds them. After nearly an hour of systematic and seemingly exhausting flipper work, our heroine seems to be done camouflaging her nest and shes heading back into the water for another year. Good work. Reporter tonight her babies will have a shot at survival. Whether future generations do is an open question. For nightline, this is dan harris in costa rica. Next, an investigation into a common household product putting toddlers hike this one at risk. Welcome to the most social car weve ever designed. The 2015 nissan murano. Recipient of autopacifics bestinclass Vehicle Satisfaction award. Now get great deals on the nissan murano. After a dvt blood clot. Mind when i got out of the hospital what about my family . My lil buddy . And what if this happened again . I was given warfarin in the hospital but i wondered if this was the right treatment for me. Then my doctor told me about eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. Not only does eliquis treat dvt and pe blood clots, but eliquis also had significantly less major bleeding than the standard treatment. Knowing eliquis had both. Turned around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt pe blood clots. Plus had less major bleeding. Both made switching to eliquis right for me. Ask your doctor if its right for you. Is the staying awake part.

Bargain market tonight a home video of a toddlers neardeath experience being used for good. Against a silent hazard in many of our homes. Hundreds have been killed or injured by Window Blinds with potentially dangerous cords. Why are they still being sold . Heres abcs chief investigative correspondent brian ross. Stand up straight, shoulders down. Reporter this is the wall family of chippewa falls, wisconsin. All nine of them. They love to make videos of everything they do. Hi interior b interior. Reporter for 17yearold gaffe advice theres one video that stands out when he was a toddler. Gaffe advices mother nicky was making a video of two of her other children, her twins. The joyful moment is about to end. As she is distracted by a phone off the hook. And will swing the camera around, catching the horrifying image of gavin that were going to show only because it has a happy ending. Gavin, gavin reporter gavin hanging by the neck from the pull cords on a set of Window Blinds. He choked himself hes blue gavin reporter then the sweetest sounds gavins parents had ever heard he was alive. Hes crying, hes making noises. Can he breathe . Reporter gavin was left with a welt across his neck but that was all. And fortunately he doesnt really remember it. And it doesnt seem to have caused any permanent damage. Reporter but unfortunately, since the day of gavins accident, some 13 years ago, the Consumer ProductsSafety Commission estimates well over 100 American Children have died, somehow caught in window blind cords. Brian, i see decades, im talking decades, about children once a month getting hanged to death by these products. And its got to stop. These are many different types of samples reporter elliot kaye, Consumer ProductSafety Commission, says hes made the elimination of Window Blinds with cords after a 30year period in which both the industry and his own agency have failed to do so. Kaye says cordless versions like this set solve the problem. Its beautiful. Reporter kayes agency doesnt have the Legal Authority to outright ban the corded versions. And he says the industry continues to drag its feet. I think its disgusting, i really do. Reporter most of the blinds sold in this country come from three major manufacturers. Springs, hunter douglas, and newell rubber maid. None of their executives would agree to appear in our report. Nor would the head of the window blind trade group, ralph vesami, outside his office in new york city. I wanted to ask questions about the children who have died in the window blind accidents. Can you talk about that at all . No. Reporter under oath in a brain injury lawsuit last year against a window mind company, vesami could not avoid answer questions. By making the decision to not eliminate those hazards, implicitly theyre making the decision to allow children to continue to be exposed to those hazards, correct . Yes. Reporter the lawyer asking the questions, jim ander, has brought more than 50 death and injury lawsuits in window mind cases. How many have gone to trial . None. Theyve all settled. Why . The documents and the testimony is too condemning. I dont think a manufacturer can afford to go to trial. Reporter the industry disputes the Safety Commissions accident numbers and has produced videos to show a range of safety features that it says have substantially cut the death rate, including breakaway cords and methods to keep cords out of a childs reach. There is no need to ban Window Blinds with cords, the industry maintains. For the 90 of American Consumers who dont have small children, the corded option may make some sense. Reporter nancy nord is a former member of the Consumer ProductSafety Commission who industry lobbyists arranged to talk with us. You cant have an environment, one where all risk has been eliminated. That just is a naive thing to want. Reporter the parents of 2yearold matt thomas strongly disagree. Would you like more . Reporter erika and Steven Thomas of suburban washington, d. C. Initially came under investigation after their son died. Even though they had done everything they could think of to make their home safe. I did everything that i knew to do to keep my child safe. And my son is gone. Reporter macks mother found him one morning lifeless on the floor, strangled when he got caught in the blind cord. She thinks he tried to look out his window at the stars that he and his brother loved so much. He wouldnt wake up. And i was screaming. I was just screaming. Then i ran out of the house with him. And i just sat. I sat on the front lawn in the mud. Reporter parents are often the first ones blamed, says linda kaiser of st. Louis. In the wake of the death of her daughter in a window blind cord accident, she also came under police investigation, leading her to set up a foundation called parents for window mind safety, to help expose the problem. When i understood, okay, Police Officers dont get it. All these people in the nation dont get it. That made me want to fight. For educating people. Reporter the industry says it too is trying to educate the public about the hazards. Many new parents may be unaware of potential cord dangers reporter including a new best for kids campaign. Yet working with our abc affiliates across the country, we found that message is not getting through, or being acted on, in many places. Is there a safety issue or anything like that . No, i dont think so. Reporter abc reporters went to major stores, asking about minds for childrens rooms, and found a confusing array of options. Often not clearly labeled. In some cases, store employees were helpful. Thats why cordless is a really good option when you have tots. Reporter in many others, employees seemed to have no idea or had not been trained about the danger. When you have the cord, you could just tie it. Tie it up. Is there a safety issue . No, not really. Reporter and our affiliate reporters also discovered that a safety warning is posted on both the corded or hazardous blinds and on the cordless blinds, which dont pose the same threat. Whats the impact when they put a warning label on something that is the same . Sheer confusion. Reporter the last few weeks the campaign on the window blind industry has had victories. Ikea and target have taken Window Blinds with cords off their shelves. They now only sell cordless blinds. We were eager to do whatever we could to increase the safety of our productions. Reporter since we began our reporting on the issue, home depot, walmart, and lowes have now announced they too will stop carrying Window Blinds with cords. But not until the end of 2018, three years away. Im thinking of not if another child is going to die but when. And i see another mother sitting in the mud. Holding her lifeless child.
