vote. >> the pope was named time magazine's man of the year. and was on the rolling stones cover. i'm thomas drayton. (technical difficulties) the 103. >> my daughter -- rocked

manhattan. disaster in new york city. and the questions about why this happened. also tonight - the cold pain of heroin addiction. >> it's too much. it's too much. i know how i raised him. i know how i raised him to live. we lived a whole some life. i don't know how this addiction took over. >> our special series focuses on heroin in a place you might least expect, why it's out of control, and why so many find themselves addicted in vermont. and who wouldn't want to float face to face in florida. what is that love worry to people who want to protect them.

things have changed, developed there rapidly and in many ways. >> sure. east harlem is a community that has been resurging has many of the communities across new york city in the five burrows have been. having been a native born and raised all of my life and going back a few generations, having seen the change your happen is certainly, you know - it's been a great evolution, we have seen the streets become safer and our communities transformed. >> a lot of community, a lot of new develop. some concern because so much of what is built is on very old infrastructure. >> that's a concern.

certainly not just in east harlem, but new york city and new york state is making sure we are not neglecting infrastructure, whether we talk about brinch, sewer lines or gas lines. the infrastructure is hundreds of years old. there was a report recently released yesterday that has brought into question that it needs to review and invest in infrastructure. it's an initiative from the local perspective. what has resulted here is a result of a gas leak that is causing an explosion and fire affecting two buildings directly, and then the surrounding area affecting a number of buildings, potentially we have 40 to 50 families who are going to be displaced as we try to figure out the structural

integrity. there'll be ongoing work that has to happen to get the buildings back in the conditions they need to be for people to live. >> ongoing investigation, i would think as well. it is awfully early to make conclusions, even to determine which building it was that might have led to the explosion or whether it may have come from underneath. we heard some of the people in the report saying that they did smell gas, at least at some point, and they want to know the report that you referred to, more than 2% of gas doesn't even reach consumers in the city because there's so many leaks - the old piping is weak and fragile. this is an ongoing problem - not just in this neighbourhood, but throughout the city and many older cities in the country. >> that's correct.

this brings to light something that we have to look at closer, and we can't come to a determination as to how this was accused until the investigation happens, but i'm looking at the broader question. being a legislature, it's imperative to evaluate and receive energy safely, and, of course, i look forward to following, you know, and reviewing the report, and working with our chair of the energy committee in the assembly figure out are we doing what we need to do to ensure the integrity here and in new york. it's reassuring to have those conversations now. further down the line we can have foresight as to what we need to do and question asked and answered. >> do you have a quick thought about whether this helps people

to focus on those needs. i recognise what you are saying. it's early in the process. certainly gives people cause to be focused on the need for infrastructure improvements, changes on that level too. . >> i agree when we talk about the infrastructure in new york state and throughout the country, we identified a number of different transportation-related plans, whether mass transit or bridges, and what is forgotten about and neglected is the sewer and energy infrastructure. all of those things are areas that we have to understand is due for an upgrade. a meaningful life for many of the projects are 30 or 50 years. we are pushing 100 and counting. there's a lot of risk out there. >> we appreciate you being with us.

when we return - mystery on the high seas - or not. the search for answers in the disappearance of malaysia air 370, and how any of us could play a key role in helping to find it.

the mystery deepens. even with the sitting of debris the the plane has not been found. the frustration is growing. time is not on our side. as every hour goes by the search area gets bigger and bigger. >> malaysian authorities believe the jetliner missing since saturday may have changed course around the time it stopped

communicating with ground controllers. earlier this week authorities expanded this search to the straightof malacca hundreds of miles from the last known position. the search area is 27,000 miles. complete with the lack of concrete details. with no clear indication of the path the plane took, frustration grows among family members of the missing. here, water bottles tossed out. the flights original destination. >> translation: i'm not very satisfied. there are many things that have not been clearly explained and they haven't met our request. >> malaysia airlines gave money to relatives to cover basic necessities while waiting word of loved one. >> the aid is provided for the basic necessities.

there was no specific conditions attached to it. the money is of no value. the mystery of the disappearance pushed them to the breaking point. >> some of the malaysia airlines staff had bad attitudes towards the search teems. the international search teams chased false leads and came up empty handed. equally mysterious is the lack of distress call from the pilots. >> we are providing assistance. we do not have enough information at the time to comment on the cause. >> the search continues. >> we will never give up hope. this we all owe to the fam lies. >> "america tonight"'s sara hoy joins us. there are sporadic reports. none seem to be panning out. if there was a possibility that the aircraft crashed on land someone would have said they'd seen something.

this was late at night, in a rural part of the area in which it went down. someone fight have missed it. it's an extraordinarily event and there are various reports. is this investigation closer to any kind of conclusion. figuring out what happened. >> there was a lot of the rumours or speculation. someone that saw one thing. >> the disturbing part is here we are five days in. the area has gotten bigger. where do we go from here, only time will tell. sara hoy, thank you for being here. >> moving to the search. that has been joined by more than 2 million people. wonder how - they are looking through a crowd sourcing campaign by a colorado satellite company. joining us via scope is digital globe director dr hanoy. appreciate you being with us. give us a light run-down on what

you are asking from the crowd sourcing contributors. what are they doing? >> absolutely, we have been fortunate to deploit satellites to capture loads of imagy, we captured 25,000 square kilometres of images. we are asking the government to analyse the situation. >> what is analyse in this context mean. >> you are asking them to look through the images that you have. >> exactly. we need people to identify what is going on inside it. >> what are they say. what are they reporting in? we are asking people to identify oil slicks, boats, and we are finding all of that throughout the search area. >> what's with the information once you have it from your contributors. what do you do with it? >> we have contributions from 2 million people. we are putting that together,

trying to aggravate to have them both and identify who is reliable and who is not. what is going on in the image. it's a computer program, converting 700,000 tags or clues into a handful that could lead to the recovery. >> have officials in malaysia, china taken you up on it. have they received it at all. >> we haven't found a smoking gun to date. we are working with major customers waiting to receive the contributions. >> what about in previous cases. there has been opportunities for you to use the product in natural disasters and personalized disasters. >> absolutely. it goes around once a week. we are able to image and launch the crowd sourcing capability

for nearly every major disaster. throughout these events we convert all the imagery into maps. where the schools are damaged, where the roads are damaged and will need infrastructure investment. we prepare to for people on the ground, for government and commercial companies. if folks are interested in the economic recovery. >> what about such disasters as super typhoon haiyan or other events like that. >> absolutely, we have tens of thousands of people helping us comb through hundreds of thousands of injuries. we convert the imagery, identifying individual instructours to get the best help for the recovery. >> terror of product development from digital globe. we hope your developers do find something. >> thank you for having me.

>> open yet addiction is an urgent and growing public health crisis. just department officials include be the d.e. and other local and state leaders are fighting back. it will require enforcement as well as treatment. the justice democratic is committed to both. >> beginning our essential series from one town ripped apart by the crisis, here's correspondent adam may. >> jail institution and death, i've been through it all. i really didn't think i'd be sitting here today. >> people here don't even make enough money to get by, but they'll get rid of their food cards, they'll do whatever means, go without food, they'll steal from friends and family just to get one more.

>> per wi heroin is striking small towns like this town in vermont. >> no matter what, 24/7, you're plotting in your head on how to get the next high. it's an every day struggle, an every second struggle. >> vermont ranks number two in the country for people seeking treatment for open yet addiction. tucked away between trendy restaurants is veinty house, a halfway home for addicts trying to beat the odds and get clean. matthew and ashley were two hard core heroin addicts now going through recovery. >> how hard is it? >> it destroys you, it really does. mentally, you're all over the place. you're happy, you're sad, you're miserable, you're excited and physically everything on your body hurts, everything. you deal with it for the rest of your life. there's no -- you don't graduate

from addiction. you're not cured. >> after trouble with the law and about a dozen overdoses that put her in the hospital, ashley, who's only 21, hit rock bottom. >> i didn't even think i would make it to 21. >> matt's addiction cost him a successful career as a computer technician at the department of home land security. >> it was great, you know, having a good job, being able to travel, making really, really good money and to be able to spend twice as much of that in a year's period of time and sit there and wonder how did i spend that much money on drugs when i only made this much? >> since last year, deaths from open yet overdoses have doubled in vermont, the number of residents seeking treatment has increased 771% since 2000, almost everyone we spoke to here

knew someone affected by addiction. >> i don't know has to do, because the pain hurts, it's just too much. it's too much. i know how i raised him. he had the best of everything. he went to sunday mass, we went to the grandparents house every sunday, we lived such a wholesome life and i don't know how this addiction took over. i don't. i don't know how it took over. >> carol is one of many broken parents of children in the grips of heroin addiction. she asked that we not show her face. >> your son was going to come here and talk to us, as well, and he decided not to. >> correct. >> why? >> it's a vicious cycle, it's a game. he'll say and do whatever you want to hear, but not follow through with it. >> he says he's been clean for seven days now. do you believe him? >> absolutely not.

i know nothing about addicts or drugs, but i'm learning a lot. i wake up every morning and i thank god that my son's still alive, i think. i think. i haven't heard from him. i think. i think he's ok. i think he hasn't gotten in trouble with the law. i want to try to keep him alive, but i don't know how to do it anymore. i don't know how to do it anymore. >> do you think he at all considers how this has impacted you? i don't think they care. i don't think they care, as long as they get their fix. >> how serious is the heroin problem in vermont right now? >> right now, my patients tell me you can find heroin and every corner, street corner for example, it's in every town. >> the doctor is one of vermont's leading addiction specialists, she says the current heroin invasion can be traced back to the abuse of cheap, powerful pain killers

that were too easy to get. >> i think it is a particular problem in rural states, perhaps boredom, not sure. i was in primary care and i remember seeing it. i moved here in 1999 and in the early 2000, 2001 i started seeing a bunch of 20-year-olds come in with habits of oxycontin. to me, that was sort of the turning point of how things started. it started out with pills. >> pills that were crushable and easy to snort. the doctor believes pharmaceutical companies could have done more to prevent this epidemic. >> how did heroin become the problem here? >> the company chose not to put a coating around the medication that would have made it very difficult to snort. most of these kids started out snorting the medication. if they had put the coating around it, it might have stopped this from the beginning but they chose not to for chick reasons, financial reasons.

when they decided, the company decided that they were then going to put a coating, the cost of the drug went way up and the heroin dealers moved in. >> with percocet and other powerful pain killers going for $80 a pill, heroin became the cheaper alternative. heroin dealers saw a major market in towns like rutland and major profit. >> what we're seeing is we're right near new york, near massachusetts, near connecticut and people can take a couple hour trip down to these places and score some really cheap heroin and sell it for a lot more here. >> we didn't know that she was using drugs until she was in the cocaine addiction around the age of 15 to 16. that's when things got so bad that we had to admit that something was wrong, and seek treatment. >> patrick martin's daughter sarah started using drugs in

high school, but with treatment, her parents thought she was out of danger. >> she had turned her life around and applied to college. life was good. she had a good job, she was vibrant. we were ready to see what was in the future for her, because we knew it would be good. >> but martin's life shattered one night when police knocked on his door. >> it was devastating. i had a loss before, but never the loss of my child. nobody should be burying their child. nobody should be trying to figure out the clothes they're going to put them in in the casket. >> martin said his daughter's body was dumped in a hospital parking lot after she died slowly from an overdose. the heroin was 82% pure and mixed with cocaine. >> she died a very slow death at the apartment of the people she was with. they sanitized the place as she was dying. they knew that she was going

that she was gone, and they took care of themselves first. >> are you haunted by those questions? >> absolutely. i'm haunted by the fact that the people that were with her are still out and never got charged with furnishing those drugs. one is local, still dealing. >> this is the bench that sarah used to sit on. >> this is the bench. >> after her death, patrick and his wife started coming by this bench in downtown rutland. it was sarah's favorite spot to relax and where they decided to start a support group for others like them to help families understand and cope, they named the group with it's end. if we say to one other person, help one other person live, help another family save their child, then her life won't have been in vain. she was so much more than drugs.

>> adam may, aljazeera, rutland, vermont. >> joining us to talk about this dramatic increase in the number of heroin users even in places like rural vermont is rusty payne from the drug enforcement administration. the thing that strikes us is this seems so out of what we think of in a place like vermont. it's anywhere and everywhere and with anybody. >> no demographic limits. this knows every demographic rural, urban. >> even in your own family you have seen this happen. >> we have seen this in my own family as recently as 48 hours ago, a relative on my wife's side died of a prescription overdose. >> of an open yet substance, so this really is reaching in all corners. we heard earlier this week attorney general holder speaking about this, the governor of vermont stepped forward in the state of the state address and said this is the main, the singular issue facing his state.

has this happened truly that rap bidly that it's taken over and become such an important topic. >> in the last five years, we've seen a huge spike in both prescription drug open yet addiction and overdose deaths as well as that transition to heroin. the biggest thing an addict wants to avoid is withdrawal, whatever they can get and open yet withdraws what they're trying to avoid. prescription drug addiction is extremely expensive and the cycle of addiction, you go from popping pills to crushing and snorting to injecting and then on to the heroin because at some point, you hit that ceiling with the pills and either a financial ceiling or you're $100 a day habit can go to $10 a day habit with heroin. >> buy one of these prescription drugs and grinding it up or as the doctors pointed out, there's a pretty big cost difference. >> that's exactly what we see, increased heroin production

globally specifically in mexico. are law enforcement seizures on the border up 400% between 2008 and 2012. drug trafficking networks from mexico and oversee distribution in the united states, they prey upon these areas that are vulnerable to pill addiction, and there's no better way to drive a market than to sell a product really cheap. you drive addiction and you get repeat business. >> that's supply and demand. >> correct. >> just an economic issue. now the thing that strikes me as attorney general holder stepped forward and said look, the federal government's going to get involved but what can the federal government do beyond the drug interdiction in this sense, at this local level what can you do? >> as much attention that we can give to this problem, we need to do it, talk to our kids as a much earlier age and explicitly about drug abuse and addiction. >> and to communities, as well. >> absolutely and make sure people understand if you're in a

tough place, an addict, there's help out there. we're a country of second and third chances. drug courts are huge in this country as are treatment programs. >> i do want to ask about a specific treatment and that is one of the recommendations that attorney holder made had to do with the use of the antidote material and that first responders could actually be required, encouraged to carry it, because there's so much on the street. >> typically d.e.a. is not a first responder. other focus is on drug trafficking orgs, the people that are bringing this stuff in across the border and who are the large scale traffickers. but any efforts that first responders can make to help those in need and that seems to be one that is working for some, i think that's going to be an effort that you're going to see more and more. >> if this can happen in your family, rusty, with a d.e.a. official as part of your family,

what advice can you give when you talk about giving advice to people, encouraging young people not to get involved in these kind of drugs, what advice can you give? >> it starts in the home. the advice that i can give is drug abuse means death, maybe not physical death, but death of your dreams, death of your potential. drug addiction robs people of what can make them great, the things that they've been blessed with, out the window, it destroys families, communities, and it destroys lives and you can die. we've seen it. i've seen it in suburban virginia where i live in a relatively upscale community. we lost a young lady 17 years old to a heroin overdose just four or five months ago, a girl from my church died from a heroin overdose five or six years ago, it's around us. it starts with pills and transitions to heroin. we don't have a -- we have an addiction problem.

we don't have one versus the other. we have an addiction problem. and when people can't get their hands on pills or its too expensive, they crave anything that can get away from withdrawal, has open yet high and they oftentimes turn to heroin. >> is there a sense though that people understand when the attorney general comes forward, we are thinking about law enforcement, about things that the grand scale of things. now do you have a sense that people are starting to get that message when you see something like adam's report when you have the kinds of experiences that you have had in your church and community that hey, this is not some sort of street drug urban crime problem, this is everybody. >> we hope so, but again, it starts in the home. >> in all cities? i mean do you see it across the country? >> absolutely. absolutely. open yet addiction, heroin abuse and addiction cuts across all 50 states over every demographic line, soccer moms, 25-year-olds,

college kids, i mean, this is a big deal for across the board. >> with that in mind, have there been particular urban areas the federal government thinks needs to be focused on? >> certainly urban areas, inner cities, you can get heroin cheap pretty much anywhere. that's the case in urban america, as well. >> 2010 according to c.d.c., we lost over 16,000 people to prescription drugs. we lost over 3,000 to heroin. that's almost 20 for us people and that was four years ago. i hate to see what the numbers are, there's usually a lag time. i hate to see what those numbers are for 2012, 2013, 2014. these aren't just numbers to hang on a story line. >> they are people and real lives. >> absolutely. >> all right, thank you very much for being with us here. >> our special series, addicted in vermont continues next time on this program when

correspondent adam may investigates a state in relaps and desperate people looking to get clean. >> in vermont now, you'll see insurance only paying for two weeks at a rehab facility. i think that's bizarre. in my first two weeks, i wasn't ready. >> what's working and what's not, as vermont fights the rampant spread of heroin in its quiet communities, thursday on america tonight. ahead after the break, with this crisis threatening to spin further out of control, ukraine turns to the white house for help. >> twenty five years ago, pan am flight 103 exploded in the skys above lockerbie. only one man was convicted of the attack >> the major difficulty for the prosecution, that there was no evidence... >> now a three year al jazeera investigation, reveals a very different story about who was responsible

>> they refuse to look into this... >> so many people at such a high level had a stake in al megrahi's guilt. lockerbie: what really happened? on al jazeera america

>> almost two weeks after russian troops invaded crimea, the standoff is no closer to an end. this week, a referendum to decide whether the pips la should remain part of croatian territory or part of russia. president obama pledged support for that nation and warned russia to back down. >> we will continue to say to the russian government that if it continues on the path that it is on, then not only us, but the international community, the european union and others will be forced to apply a cost to russia's violations of

international law. there's another path available and we hope president putin is willing to seize that path, but if he does not, i'm very confident that the international community will stand strongly behind the ukrainian government in preserving its unit and its territorial integrity. >> that is the question. what is russia's next move. the uncertainty is certainly being felt across and in crimea at this hour. in the capitol of ukraine, the government is increasingly looking to the united states and europe to help and the impasse, as fears around insecurities grow. aljazeera's reporters are covering events across the region. we begin with phil ittner. >> here in kiev there is a mixture of hope and anxiety, hope because they're expecting something tangible to come back

from that delegation in d.c. both in terms of economic assistance, but also military assistance, non-lethal. there is information from intelligence gathering communities that there are russian nationals coming across that border with the intention of agitating and causing addition reputation between those who lean towards the west and those who lean towards russia. >> this is word that this weekend, they can expect to see some of that disruption from those agitators, because that's at a time when that very important referendum will happen and if there's disruption, it may send a very clear message that it might be best to vote in favor of returning to russia. >> phil ittner in the ukrainian capitol. >> the eyes are focused on the

upcoming referendum. jennifer glasse is in the seaside city in crimea where russian warships continue to block the support and the ukrainian navy fleet. what are sunday's expectations for the vote? >> many believe that sunday's referendum will correct a mistake made 60 years ago when then satisfactory jet leader gave crimea to ukraine. many here have believed that it should have always remained a part of russia and the vote will correct that. there's suspicion here. the train station this morning, when the train came in from a kiev there were members of the people's defense force, local crimea thats loyal to moscow watching to see who would get off the train. we've also seen check points around the city, checking to see who's coming in and out of the country and of course crimea's airport has been closed to all flights exempt those from moscow.

while many here believe that the referendum is a done deal, the majority ethnic russian population will vote to head towards moscow. there are those worried what it might mean, not least the sailors of the black sea fleet blockaded on their ships for 10 days now. >> ahead in our final thoughts this hour, is it just too much love? florida's lumbering sea cow the manatee, why those who may want to get up and personal may be a threat to its future. >> i thought that she was my property, and i could do as i please. >> abusive men... >> this is completely unregulated.. >> easy access to guns... >> there's somewhere around 1600 women being held every year >> a deadly combination... >> death could have been prevented... >> her and a hundred more women... >> it hurts to the core >> faultlines al jazeera america's hard hitting...

ground breaking... truth seeking... >> they don't wanna see what's really going on >> break though investigative documentary series death in plain sight only on al jazeera america

only on al jazeera america >> finally from us this hour, the florida manatee is by conservation standards a success story. by the early 1940's, there are estimated less than 400 of them remaining but with more protections now in place, thousands are swimming in florida once again. will the future of the ma'am malls be in more trouble soon? on thursday in miami, environmental activists and developers face off about plans

to build more docks on waterways for boaters in central florida. environmentalist reject the plan as more harm to the sea cows. >> we discovered in the crystal river of florida, these lovable creatures may be too popular for their own good. >> the very small area, two acres and seven acres right here. we're going to see manatee activity behind the boats on the surface, very likely a mating herd. >> it's just past down on king's bay on the west coast of florida. a u.s. fish and wildlife ranger knows every inch of this body of water. >> about nine miles away, they can go feed and come back. >> right now, the bay is serene, empty of boats and people but filled with an exceedingly rare and endangered wildlife.

>> manatee is the only marine mammal that initiates contact with people because of curiosity. >> do you think they actually make a conscious choice. >> yes, they do make a conscious choice to interact with people. they know. >> it's that promise of interaction that by noon creates gridlock rivalling rush our in times square. now more than 250,000 a year flock to this small bay. it's about half a square mile. >> most of the people that live here in king's bay, they are not liking the fact that there's no limits, no thresh holds, no caring nasty how many visitors at one time can come to the bay. most people in town are happy. >> money, money, money. >> it depends an manatee eco tourism. >> king's bay is one of the only places in the world where you can swim with and even touch

groups of endangered florida manatees. hot springs beneath the by provide bathroom water all year round. manatees need that warmth to survive winter codes. it's critical machine tee habitat. >> we have fat, healthy happy manatees here. >> mike is a skilled diver, tour boat drive and manatee guide. >> we have 400 coming here. >> that's a lot. >> that is a lot. >> krystal river is named one of the thousand places to see before you die in that in the new york times best seller of the same name, manatee eco tourism is the life blood of that small town on the shore, population 3,000. eco tourism and the hundreds of thousands of tourists it brings has set off a debate. >> what do tourists get with

swimming with the manatees. >> you only touch what you love and only love what you know. we are fostering a steward ship. once we come face-to-face and such something, it's real to us. >> the swimming with manatees attraction is his livelihood. >> manatees will behave much more like cats and not so much like dogs. >> we call them gentle giants. they're so engaging and curious and they move in slow motion when they're looking at you and there's a connection when you look in their eyes. >> every day, he takes visitors underwater, and often swimmers will pelt or touch the manatees, which is legal here. some conservationist the want the tour boats eliminated because they believe snorkelers and boats are disturbing the animals. at the very least, some insist

touching should be banned. tour boat operators argue it turns visitors from tourists to manatee advocate and on the water, there is lots of enthusiasm. >> it gives me chills thinking about that, cusping something to me which has always been so elusive. >> it was so different from anything i've ever done. they're so big and right there and you can just reach out and touch them and they're not going to do anything. >> they do have roped off sang waters that they can escape to where the overcrowding becomes too much. they are off limits to the public, but sometimes as we saw, tourists go there anyway. >> hey, ma'am, you aren't supposed to be in there. you see that says closed area. >> we're going to go up here this way. >> tracey leads kayak tours of the bay. she films what she calls manatee harassment by divers and tour operators.
