reporting tonight, carl quintanilla. >> good evening. >> the long manhunt for those two convicted killers who escaped from a new york prison is over tonight. david sweat was shot and apprehended near the canadian border two days after richard matt was killed in that confrontation with police. this photo of sweat was taken just after his capture, his condition is unknown. but we are learning more tonight about what led authorities to some of the most wanted men in the united states. we begin with nbc's stephanie gosk. >> reporter: after 23 days on the run, after a prison break that captivated the country, 35-year-old david sweat is in custody tonight, shot and wounded by law enforcement just two miles from the canadian border. >> can we get an ambulance to stage at the constable station for any possible further responses? >> copy. give me an ambulance to stage at my station for malone, please. >> reporter: authorities say sweat was taken to a nearby hospital for treatment. roads surrounding the area remain blocked off by state troopers.

>> i heard a lot of sirens, and i live right over here. and he was only a mile away from the border. he was a mile away from canada. >> reporter: authorities had been searching for sweat in a 22-square-mile area in the woods where his partner richard matt was shot and killed on friday, south of malone. it appears that sweat had moved well beyond that area toward the canadian border. the two convicts triggered a huge manhunt after they escaped from clinton correctional, a maximum security prison, cutting through walls and sawing through steam pipes. breaking through a two-foot-thick brick wall and making their way out of a manhole to the street. prison worker joyce mitchell was supposed to be their getaway driver, but sources familiar with the investigation say she got cold feet and instead went to the police. she allegedly smuggled tools to the inmates inside frozen hamburger meat. a correction officer gene palmer has also been charged with promoting prison contraband along with other offenses. this man has more reason than

most to be relieved that the manhunt is over. >> look at a picture of richard matt. that was the devil. >> reporter: lee bates was richard matt's accomplice in the 1997 murder of a businessman and testified against him. he was worried matt might come looking for revenge. >> i thought, is it real? is this finally over? and part of me wanted to say, i got to see this because i don't believe it. and then certainly i saw enough through reports and on tv and the nightmare had ended. >> reporter: according to multiple sources familiar with the investigation, just about a mile down this road, new york state police sergeant jay cook saw a man dressed in military clothing leaving the forest. he thought he looked suspicious and he told him to freeze. instead, david sweat ran. so sergeant cook fired his weapon and hit sweat in the shoulder.

he was cuffed and later taken away. carl? >> stephanie gosk in upstate new york, stephanie, thanks. for more on david sweat's condition let's bring in john yang who is in malone, new york. john good evening. >> good evening, carl. he had been transferred to the albany prison center. new york governor andrew cuomo declared the nightmare is finally over. he praised the state and federal law enforcement officials who made this happen singling out new york state police sergeant jay cook. he was on patrol by himself when he spotted sweat and appear hebldrehended him. once sweat is treated for his wounds and recovers he will be heading back to prison but not to the same prison he escaped from. the department of corrections says they have already got a spot reserved for him in another maximum

security prison but they're not telling us where. carl? >> nbc's john yang in malone new york tonight. john, thanks. >> there was a stunning explosion over the skies of cape canaveral today. an unmanned rocket bringing supplies to the international space station blew up just two minutes into its flight. it's another setback for nasa and spacex, the company that will one day carry astronauts into orbit. here's tom costello. >> one mission sequence start and liftoff. >> ignition sequence start. liftoff of the spacex falcon 9 rocket. >> reporter: cast against a deep blue sky, what appeared to be a perfect liftoff from cape canaveral. on the beaches blow, spectators had gathered to watch, but only two minutes into flight, a massive explosion. >> we appear to have had a launch vehicle failure. >> reporter: on board the rocket, food, water, scientific experiments, a replacement spacesuit and parts for a water purification system. it's the third cargo ship to be lost in eight months.

last october another private company's rocket blew up on liftoff, then a russian progress ship spun out of control after reaching orbit. >> there's really no commonality across these three events other than the fact that it's space and difficult to go fly. >> reporter: shortly after the explosion, elon musk tweeted there was an overpressure event in the upper stage liquid oxygen tank. on board the orbiting space station astronaut scott kelly tweeted watched dragon launch from space station. sadly failed. space is hard. scott then called his twin former astronaut mark kelly, now a spacex and nbc news consultant. >> he's not talking about eating the mustard and ketchup packets yet, right? so they've got a lot of food on board. they have a lot of supplies. >> reporter: the next russian resupply ship lifts off friday. spacex and boeing are slated to fly astronauts to the station in 2017. a first for the private sector since the space shuttle was retired.

>> before they put a human being on a spacex rocket, they're going to have to be absolutely certain that this kind of failure won't happen. well, that's impossible. so the real answer is you have to be as certain as you can possibly be. >> reporter: spacex has launched six successful cargo missions before today. importantly it said today that had this been a manned mission, the rocket would have had a crew escape system that it believes would have ejected the crew capsule away from the explosion and saved their lives. carl? >> tom costello tonight, thanks. there's a growing mystery in a small ohio town tonight. six women have disappeared over the past 13 months with residents fearing it could be the work of a serial killer. gabe gutierrez reports. for yvonne boggs, the uncertainty is overwhelming. >> i can't sleep, i can't eat. it's probably the hardest thing in my life. >> reporter: her daughter, charlotte trego has been missing

since may of 2014. she's one of six women who have mysteriously disappeared in and around chillicothe, ohio, in little more than a year. four of them have turned up dead. >> we want answers. we all want answers. we want to find out who is killing these girls. >> reporter: in this small midwestern town, there are growing fears of a serial killer. investigators say some of the murdered women may have known each other and most have been found in or near bodies of water. >> found a woman's body in the creek. she's wrapped up in a blanket. >> reporter: tiffany sayre's remains were discovered just days ago. >> we love her and we miss her. and we just want them all home. >> reporter: police are trying to calm fears. detectives say some of the women were prostitutes battling drug addiction. >> there's been a lot of talk of serial killer. we haven't found any evidence that links these females to one person or persons, but

we're not leaving anything off the table. >> reporter: the fbi is now assisting the investigation digging into the past of each of the women. >> who did they hang out with? who is on their cell phones? who did they spend time with? who did they have as associates? or peripheral friends? the answer may be there. >> reporter: yvonne boggs doesn't know what to believe. >> not hearing from her is just, you know, it makes me wonder whether she's still alive. >> reporter: she just wants her daughter home, and this chilling mystery solved. gabe gutierrez, nbc news. now to the severe weather impacting the country from coast to coast. everything from a major dust storm out west to deadly flooding in the east. we get the latest tonight from nbc meteorologist dylan dreyer. >> reporter: this weekend's deadly and destructive storms responsible for at least four fatalities. on maryland's lake linganor one man was killed and eight injured when their boat was swept over a dam. the heavy rains blamed

but it was a very different scene overseas in istanbul where police used tear gas, even a water cannon to disperse crowds gathered at that city's pride parade. officials in this country are voicing new concerns that isis will use social media to inspire lone wolf attacks. while they're wear of no specific plots, law enforcement's asking everyone to remain vigilant heading into the fourth of july holiday. this comes amid a grim milestone in the fight against isis one year since the group proclaimed statehood. we get more from nbc's bill neely in iraq. >> reporter: exactly a year since isis declared its new state, a year of mayhem and massacre. in the last week alone, it claimed 200 victims in the syrian border town of kobani. like syria, iraq is locked in battles with isis, its army struggling after fleeing from two major cities. this iraqi soldier says the army is outgunned by isis. this policeman's older brother was hanged by isis, his younger brother shot.

he, too, was hit, but escaped. what's america doing, he asks. we don't want your troops, but we need your guns and help. they feel abandoned. nothing. american air strikes he says are achieving nothing. most of these people simply don't understand why america isn't doing more to fight isis. one man told me when the americans pulled out, they left us not in paradise or in hell, but they left too early. iraq's shia militias are preparing to attack isis in ramadi, which fell last month. they're armed and advised by iran. their commander told me they'll push isis out of iraq's biggest province. but after thousands of u.s. air strikes and a pentagon estimate of 10,000 dead militants in iraq and syria, isis may be degraded but it's not defeated.

in its wake, the worst refugee crisis ever in the middle east. millions in camps emptied of hope as the world's most violent terror group keeps its grip on a broken country. bill neely, nbc news, anbar province, iraq. when "nightly news" continues on this sunday, an nbc news investigation. stunning allegations at one v.a. hospital claims it overmedicated patients with deadly consequences.

last year the department of veterans affairs was rocked by allegations with problems in its medical system most notably long waits for patient care. another controversy in wisconsin. allegations from whistle blowers first reported by the center for investigative reporting that the chief of staff and other medical personnel have been overmedicating mental health patients. here's nbc's ronan farrow. >> nobody has been held accountable for what happened in the past with my son. >> reporter: marvin simcakoski's son jason, a former marine, died last summer while being treated in tomah, wisconsin for conditions including anxiety and addiction to pain medication. his cause of death? mixed drug toxicity. according to a county medical examiner. the v.a. had prescribed 14 drugs including pain killers and tranquilizers. >> it said 14 in the autopsy report. we didn't know that, but it was in the autopsy report. >> reporter: the doctor in charge of the prescription policies was dr. david houlihan. some patients and

staff called him the candyman. and the hospital candy land. according to v.a. documents obtained by the center for investigative reporting, prescriptions for four common opiates at tomah quadrupled after 2005 when dr. houlihan became chief of staff. >> these veterans come out worse than when they went in. >> all drugged up. >> reporter: jason simcakoski wasn't the only patient to die under dr. houlihan's care. carrie hem has spent years piecing together evidence about what happened to her brother, army veteran craig farington. he died eight years ago hours after being released from tomah. what conclusion did you reach from all of this? what happened to your brother? >> they killed him. >> reporter: according to his death certificate signed by a county medical examiner, farington died from a poly medication overdose, a lethal mixture of prescription medications. the v.a. even paid the family $97,000 to settle its wrongful death claim. when you hear that

there was a death that was so similar to your son's so many years earlier, how does that make you feel? >> sad. sick. i think, you know, if things would have -- if action would have been taken back then, i think there would have been -- my son probably would still be alive today. >> reporter: this spring, after scrutiny from whistleblowers, congress and the media, the v.a.'s secretary ordered a review of prescription practices at tomah. it found that unsafe clinical practices have caused patient harm and that an apparent culture of fear at the facility compromised patient care. another office, the v.a.'s inspector general has conducted reviews including one released just ten days ago that reached a different conclusion. they did not substantiate the majority of allegations about tomah or about dr. houlihan, the alleged candyman. dr. houlihan's lawyer point to those inspector general reports as a strong rebuttal to what he calls baseless accusations. he says the v.a. won't

allow his client to discuss patient care or his official duties. dr. houlihan remains on administrative leave with pay as investigations continue. >> i want to express my sorrow and regret for your loss. >> reporter: at a congressional hearing this month, the v.a.'s dr. carolyn clancy addressed families of patients who died and said a safety initiative started three years ago has cut the number of veterans receiving narcotics. why it is that it took seven years after farington's death for a thorough investigation to happen? >> what i think is that some of our usual investigative tools are much weaker than we thought. and that's one thing we are learning from the investigations at tomah. >> reporter: dr. clancy later told us even one death that could have been avoided is too much. >> something needs to be done to send a strong message that this shouldn't happen again to the veterans out there. >> reporter: this past week, the simcakoski family was in washington. as wisconsin's two senators co-sponsored a bill aimed at preventing

overprescription at v.a. hospitals, a bill named after jason simcakoski. ronan farrow, nbc news, tomah, wisconsin. up next, a famous mobster with some words of wisdom.

he's one of the most notorious gangsters in history, but now whitey bulger is reflecting on his past and offering advice you might not expect. here's nbc's hallie jackson. >> reporter: from a florida prison cell in careful cursive, one of the most notorious gangsters confesses he took the wrong road. whitey bulger writing, my life was wasted and spent foolishly, brought shame and suffering on my parents and siblings and will end soon. but bulger didn't mail this to the fbi or his victims' families. he sent the letter to three teenage girls. >> we were so shocked when we got the letter. it was huge. we didn't expect it to go this far at all. >> reporter: the friends had been working on a project at their boston area high school about leadership. instead of picking a president or ceo, they profiled bulger, a violent crime boss captured in california after more than 16 years on the run and

convicted for his role in 11 murders. in his letter, bulger warned the teens not to look to him for advice, but he gave them some anyway. i know only one thing for sure. if you want to make crime pay, go to law school. >> to see him show remorse and to be despondent for us acknowledging him as a leader, i think that was the most interesting aspect. >> reporter: no remorse for his victims. only regret for himself. a gangster looking back at a life that will end behind bars. hallie jackson, nbc news, los angeles. when we come back, a daring rescue mission to save those trapped on mt. everest.

we end tonight with a story of incredible heroics. it's been two months since an earthquake triggered a massive avalanche on mt. everest, leaving climbers stranded. tonight nbc's richard engel brings us the story of one man who jumped into action. >> reporter: at 17,598 feet above sea level, this is everest base camp. on the morning of april 25th, filmmaker michael cherten was relaxing with teammates in a tent when -- >> the first sense is you feel a little bit of a shake. so i jump up, run, get

my camera, start rolling. >> reporter: the earth was shaking. michael turned his camera toward everest. >> it was at that moment that out of my peripheral i see this massive wall of ice, snow and i just yelled down. >> reporter: the earthquake, magnitude 7.8, had unleashed a massive avalanche that hit base camp like a shock wave. and scores of seriously injured people urgently needed to be medevacked, but all the rescue helicopters were grounded. >> we were here stuck in bad weather. >> reporter: when we first met rato rush he was still ferrying the wounded and the dead off the mountain. >> just wanted to be up there and see what we can do, what we can help. >> reporter: so rato got in his chopper and as soon as he spotted a hole in the cloud cover, he flew right through it. and other helicopters couldn't come? >> no, the weather was just -- the weather

was too bad. >> reporter: rato headed for base camp. >> as soon as we landed there, you know, they opened the door and got the first severely injured people in there. >> reporter: he dropped off the wounded at this tiny mountain clinic. alone in the sky, he ended up making 35 round trips before heading even higher to pick up more injured climbers. it makes you very uncomfortable if i called you a hero. >> yeah. >> reporter: is this just a swiss cultural phenomena or are you -- >> i think so. no, i'm just an ordinary guy here. you know. >> reporter: but this ordinary guy personally rescued about 70 people. richard engel, nbc news, nepal. >> you can catch much more of richard's reporting on a special edition of "dateline" coming up next. that's "nbc nightly news" for this sunday. here tomorrow. i'm carl quintanilla reporting. for all of us here,
