Reporter el nio round two is packing a punch. This morning, mud cascaded down hillsides right on to the freeway; drivers stuck in rising water were rescued from their swamped cars; and several feet of snow blanketed the mountains. These storms battering the west coast also drenched arizona, where a man and his young grandson were pulled from their hummer after getting swept up in raging floodwaters. Samantha young is the childs relieved mother. Unbelievably thankful. I said thank god a thousand times. It wouldnt be enough. Reporter record amounts of rain have fallen in parts of los angeles, and the National Weather service says a gustnado damaged eight buildings near downtown, ripping off part of the roof and blowing out windows. But the region is also getting something it desperately needs water. Some of the billions of gallons of storm water inundating rivers in los angeles are being where they replenish groundwater supplies. Gary hildebrand is the Deputy Director of the public works department. How much water are you capturing in these places . Well, in the storm that occurred yesterday, for example, we were able to capture 1. 6 billion gallons of water, which is enough water for around 40,000 people. Reporter the concern now are these saturated hillsides like this one that burned in a recent wildfire. The mud is streaming off the hillside, and at the base of it you have a bunch of homes and a bunch of very worried homeowners. Scott, if there is any good news tonight, it is that the rain that is forecast for tomorrow, is expected to be much lighter. Pelley ben tracy reporting. Thanks. Also in california today, a state of emergency was declared over a massive natural gas leak near los angeles. Thousands were evacuated from l. A. s porter ranch neighborhood after people there complained of nausea and headaches. The methane has been blasting out of a broken well since and today in michigan, an emergency was declared in flint, where the Drinking Water is contaminated with lead. Last october children were found to have elevated levels of lead in their blood, after the city started using water from the flint river to save money. Tonight, scientists doubt north koreas claim that it tested a Hydrogen Bomb, which would be far more powerful than the three atomic bombs that its tested before. Data from seismographs indicated a blast last night equal to around 7,000 tons of t. N. T. But thats not large by atomic bomb standards. Seth doane begins our coverage. Reporter a perfect success was how north koreas state media put it. Defending its Nuclear Arsenal as a powerful deterrent against the chieftain of aggression. The underground test registered as a 5. 1 magnitude quake. It was close to the site of three Previous Nuclear tests. The news sparked cheers in north korea, and rattled nerves in south korea, which questioned whether the explosion was big enough to be a Hydrogen Bomb. North korea is known for its saberrattling, but possessing a Hydrogen Bomb would be a major and surprising step forward. When we were in north korea last october, it appeared relations with china, its biggest ally, were warming. China had sent a top official to the ceremony. But there was no hint of that today. Chinas Foreign Ministry condemned the test. Will there be some action on chinas part . China has been using words and actions, spokeswoman hua chunying said, but from all parties. Ultimately, scott, north korea wants to create a Nuclear Weapon capable of reaching the mainland united states. And regardless of what exactly was tested, this likely provides more research, and another step toward that goal. Pelley seth doane reporting from beijing tonight. Seth, thank you. North korea also claimed that its Hydrogen Bomb was miniaturized to fit on a missile, which would be a huge engineering achievement, also unlikely. David martin is at the pentagon. Reporter u. S. Aircraft flying out of japan will collect air samples off the coast of north korea to determine exactly what kind of Nuclear Device went off. But based on analysis of the seismic wave the blast triggered, u. S. Intelligence is highly skeptical of the north korean claim it successfully tested a Hydrogen Bomb. Last nights explosion is estimated to have been less than power of the weapon which destroyed hiroshima at the end of world war ii. A Hydrogen Bomb, which has never been used in war but was tested in the pacific during the 1950s, would be 50 to 100 times more powerful. Whatever kind of device was detonated, the greatest mystery about north korean Nuclear Weapons is whether they have the capability to launch one against the united states. North korea has a missile capable of reaching that far, but it has never been tested. To be on the safe side, the u. S. Keeps its Missile Defense system, which Officials Say is capable of shooting down a small number of north korean missiles, on constant alert. North korea seems to specialize in nasty surprises. U. S. Intelligence had expected another test sooner or later,t but they had no warning it would happen last night. Scott . Pelley david martin reporting tonight. David, thank you. Well, worries about chinas slowing economy shook up the dow closed, off 252 points. Oil finished below 35 a barrel for the first time in nearly 12 years, and we note that chipotle t lost 22 a share today. It is down nearly 38 since an e. Coli outbreak at its restaurants in the fall. 26 days, now, before the voting in iowa, and Republican Donald Trump is questioning the birth of frontrunner ted cruz. Just when you thought this campaign couldnt get any stranger, cruz fired back, with the help of the fonz. Heres nancy cordes. I really know nothing about it. Reporter a lack of knowledge has not stopped trump from claiming, repeatedly this week, that his closest competitor might be ineligible to run for president. I hope thats not going to be a problem for him, but ive been hearing a lot about it, and youve been hearing it and i guess everybody is talking about it. Reporter texas senator ted an american mother; legal scholars widely agree that makes him a naturalborn u. S. Citizen. Trump once shared that view, but has apparently had a change of heart, as cruz climbed to the top of some iowa polls. The billionaire now argues, a cruz candidacy could imperil the g. O. P. The problem is, that if the democrats bring a lawsuit, the lawsuit could take years to resolve, and how do you have a candidate where theres something, you know, over the head of the party and that individual . Reporter its familiar territory for trump, who was the figurehead for the birther movement, questioning president obamas hawaii roots. Our president has finally released a birth certificate. Reporter like the president , cruz initially brushed off trumps comments, likening them to this famously implausible scene from the 1970s sitcom happy days. Im going to stick with fonzie jumping the shark, and battle it out. Reporter but in rock rapids, iowa today, the lawyer in him took over look, as a legal matter, the question is quite straightforward, is settled law, that the child of a u. S. Citizen born abroad is a natural born citizen. Reporter legally it isnt entirely settled because the Supreme Court has never weighed in on the matter, but two past g. O. P. Nominees, john mccain and barry goldwater, were also born outside the states to american parents, scott, and neither of them faced any serious legal challenge. Pelley nancy cordes on the campaign for us tonight. Nancy, thank you. Today a texas state trooper was indicted for perjury over his account of a traffic stop and arrest of a woman who died in custody. In july, trooper Brian Encinia pulled over sandra bland for an illegal lane change. He pulled her from the car and threatened her with a taser. He claimed that she swung at him and kicked him. Well, she was charged with jail three days later. If convicted, encinia could face a year in jail. Now, we have a special investigation of what has become a plague in our country. About two million americans are hooked on prescription painkillers, and in 2012, 259 million prescriptions were written. Thats one bottle for every american adult. How could that be . Jim axelrod and producer ashley velly found out in West Virginia, a state thats attempting a drastic solution allowing addicts to sue the doctors who got them hooked. So, you spent 1,000 a week . Right. Reporter 17 years ago willis duncans life changed forever, when a coal mining accident left him with a crushed sternum and broken ribs. If i didnt have ten pain pills, i wouldnt go to work. Bottom line. It changed everything. Reporter duncan developed a lifelong addiction to painkillers, when his doctors only treatment was a never ending supply of pills. The only time you went in to see a doctor was to get your pills raised. Reporter hang on a second. You go in to get looked at, but the examination wasnt done by a doctor . No. Reporter duncan would wait for hours to be seen for just a few minutes, at this clinic where 150 patients lined up every day for pain med prescriptions. Did you ever say to a doctor, this has gotten out of hand, and i need help . Never, because you got used to them and you didnt know how the function without them. Reporter this cashonly operation allowed doctors to clear as much as 100,000 a week. Were in mingo county, West Virginia, executing a search warrant. Reporter the clinic was raided and shut down in 2010. Theres an exam room. Passed for exam rooms. Main office. Reporter piles otrash and files, loose prescription pads, syringes. And starving birds stuck in roachinfested cages. Hundreds of patient records were seized, along with thousands of undated and presigned prescriptions for addictive pain meds like vicodin, xanex and lortab. The doctor in charge went to jail for six months for negligence. Well do kind of a driveby, take a look at the place. Reporter d. E. A. Agent gary newman is part of a Team Currently investigating dozens of doctors, pharmacies and distributors throughout the state. We are talking, in a certain sense, drug traffickers, and they are doing nothing but writing and cranking out prescription after prescription after prescription. Reporter theyre pushers. They truly are. Reporter West Virginia has the highest rate of Overdose Deaths in the nation. Equivalent of one painkiller prescription for every man, woman and child in the state of 1. 8 million. Ti in the last year, the West Virginia department of health inspected 19 pain clinics. 12 were told to shut down. You can actually be so stressed that you cant sleep at night. Reporter one is run by dr. Michael kostenko, seen here lecturing tients. Hes written more than 40,000 pain pill prescriptions over the last two years at his cole country clinic. Kostenko was among those ordered to stop operating as a pain clinic, but he remains open. After weeks of trying to reach kostenko, we drove out to cole country clinic, located at the end of this narrow twomile logging road. Instead of finding the doctor, we came face to face with a rottweiler. Shutting down these clinics can often take years, because these are licensed doctors, writing therein lies the problem. You have to be able to prove, in court, that theyre prescribing was for a nonmedical necessity, or in such an egregious amount that it was negligent. Reporter among the 30 West Virginians now suing their doctors and pharmacies for enabling their addiction is willis duncan. I hurt a lot of people. I mean, its just a bad deal all the way around. I had nothing for them. Nothing for none of them. Reporter as for dr. Kostenko, this friday the state begins the process of seeking to shut him down permanently, but tonight his clinic is still operating. The state could also set a precedent by going after not just the doctors and the pharmacies, but the wholesale drug distributors in court, as well. Pelley remarkable work. Jim, thanks very much.
