>> 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 sof 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 man hole 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 murder of a businessman and testified against him. he was worried matt might come looking for revenge. >> the thought, it is 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. >> reporter: good evening, carl. we don't have an official condition report on sweat, but police tell us that he was alert and conscious when they took him in constable. now the albany medical center is telling us that they expect him to be transferred there some time this evening. two reasons for that. higher level of care. the albany medical center is a level one trauma center. this hospital here is not. also the albany medical center has a secure prisoner ward where he can be held. if he does recover, he can expect to be charged by the clinton county district attorney on escape charges and the corrections department has told us that he will not be going back to dannemora. he'll be going to another facility maximum security prison.

they've already decided where, but they're not telling us yet. >> john yang in malone new york. our thanks to you. there was a stunning explosion over the skies of cape canaveral today. an unmanned rocket brig supplies to the international space station blew up just two minutes into its flight. it's another setback for nasa and for spacex the company that will one day carry astronauts into orbit. here's tom costello. >> one, ignition sequence start, and liftoff of the spacex falcon 9 rocket. >> cast against a deep blue sky, what appeared to be a perfect liftoff from cape canaveral. >> reaching maximum aerodynamic pressure. >> reporter: on the beach below 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. the third cargo ship

to be lost in eight months. last october, another company's rocket blew up on liftoff. then a russian progress ship spun out of control after reaching orbit. >> there's really no commonality between these three events other than it's space and it's difficult to go fly. >> reporter: elon musk tweeted. onboard the orbiting space station, scott kelly tweeted watched dragon launch from space station. sadly failed. space is hard. he then called his twin former astronaut mark kelly, now a spacex and nbc news consultant. >> he's not talking about eating the muchup and mustard packages yet. they've got a lot of food. >> reporter: spacex and boeing are separated 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. >> 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, tom, 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. >> reporter: 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 have 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 preferal friends? the answer may be there. >> reporter: yvonne 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 impacts the country from coast to coast everything from a dust storm out west to flooding in the east. we get the latest from dylan dreyer. >> reporter: this weekend's deadly and destructive storms responsible for at least four fatalities. in maryland one man was killed and eight others rescued therefore their boat was swept over a dam. the heavy rains blamed for the rushing

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. 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

department of veterans affairs was rocked by allegations with problems in its medical system including 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's son jason, a former marine died last summer while being treated in wisconsin for conditions including anxiety and addiction to pain medication. his cause of death? mixed drug toxicity. 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 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 toma quadrupled after 2005 when dr. houlihan became chief of staff. >> these veterans come out worse than when they went in. >> all drugged up. >> reporter: he wasn't the only patient to die under dr. houlihan's care. carrie has spent years piecing together evidence about what happened to her brother, army veteran craig fairington. he died eight years ago hours after being released from toma. 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 he 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 toma. 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. acht'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 toma or about dr. houlihan the alleged candyman. his lawyer points 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 morks the v. acht'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 toma. >> 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 family was in washington. as with the two senators ko sponsored a bill aimed at
