"nightly news" begins right now.

>> announcer: from nbc news world headquarters in new york this is nbc "nightly news." reporting tonight, lester holt. good evening. it's now been over 60 hours since two killers staged a daring and certificated breakout from a maximum security new york prison. time enough to have put thousands of miles between them and the prison walls. tonight the hunt for the men extends across international borders while still leaving communities closest to the prison gripped by fear and anxiety. the breakout was elaborate, the men penetrating steel walls, metal locks, pipes and brick to make their escape. possibly authorities say with help. nbc's miguel al ma guerremaguer is at the clinton correctional facility. >> reporter: we're learning more about the convicts who may have used power tools toes cape the prison behind me. nbc news has learned they were housed in the so-called honor section, the a-block

of the prison where they may have had more freedom. two said to be close friends. this as we also learn prison investigators may be looking into an employee a woman who worked inside the prison and may have helped the inmates make their daring escape. tonight the international dragnet to catch two killers, widening across the u.s., mexico, and canada, where border patrol agents are zeroing in and searching tractor-trailers. police s.w.a.t. teams and the fbi with the largest presence outside the maximum security prison wall. convicts 34-year-old david sweat and 49-year-old richard matt were discovered missing 5:30 a.m. saturday during a routine cell check. font for the first time we're hearing the emergency dispatch. >> both subjects escaped from the clinton county correction facility in dannemora. unknown direction of travel. possibly southbound on 87 in a dark blue honda or ford with a

broken rear bumper. >> reporter: governor andrew cuomo retraced their steps, saying there are indications the prisoners may have had help from the inside. and according to news reports, that help may have come from a woman working with the convicts. >> they're interviewing every inmate. they're looking through the logs to see who visited these guys. they're looking through the telephone records to see who these guys called. >> reporter: a source with knowledge of the situation says the convicts were in the honors section of the prison where there's fewer restrictions on their movement. authorities say the prisoners in side-by-side cells stuffed their bunks with clothes to avoid detection, then used power tools to cut holes through the steel walls behind their beds. crawling onto a catwalk six stories up they broke through a brick wall two feet thick, cutting holes into and out of a 24-inch steam pipe they shimmied beneath the prison breaking out of a manhole more than a block away.

the convicts leaving behind a racially charged post-it note reading "have a nice day." jeremy getman spent four years at the clinton correctional facility convicted on weapons charges. >> it's a maximum security prison. so it's most definitely very tight security very tight movement as far as when you're allowed out of your cell. you're watched pretty much all the time. >> reporter: with more than 250 heavily armed officers scouring farm and forest land, the city of dannemora, nicknamed little siberia for its isolation, is tonight a fortress. within a 15-mile radius there are four colleges and 23 schools. >> they have a hard time sleeping at night. they're afraid every little noise they hear somebody is here. >> reporter: tonight, two killers on the run. as the desperate search to find them could lead authorities anywhere. as they follow 300 leads today, investigators admit they are no closer to

finding these two convicts. meantime the internal probe continues on how were they able to get power tools. tonight, lester, there is simply no answer to that question. >> all right, miguel, thanks very much. i think a lot of us when we heard this story, our first thought, it sounds like a movie. and of course "shawshank redemption" came to mind. but it's hard to believe this happened in real life, for these two convicted murderers to execute this escape plan. so many questions about where they got the power tools we heard about to pull this off and how they knew the way out. nbc's jeff rossen goes inside the escape. >> reporter: inside job or not, even veteran construction experts are baffled. first the inmates cut through a solid steel wall. here's the actual photo. david lawrence is with eastern steel. >> how long have you been doing this? >> 41 years. >> so how do you get through steel? >> well, this is a piece of quarter-inch plate. from the pictures of the prison break it looks like it could have been that thickness. >> but what kind of tools could the inmates have used? >> they could have used -- this is a

grinding wheel with a cutting blade. this is one of the tools they could have used. >> something this small that you could hide inside of a cell possibly. how long would it take to get through? >> anywhere between 30 and 90 minutes. >> look how much noise it makes. noise and sparks. keep in mind there was construction happening at the prison at the time. some believe the inmates timed their noise with the real construction noise. >> this is another option. oxy acetylene torch. a lot faster a lot quieter. >> he's been doing this for three minutes and he's already all the way through. >> reporter: once through the steel, another obstacle. this two-foot brick wall. we've set this up to show you just how thick that wall was. this is about two feet. i guess these guys just carried their tools around with them but what would get them through this? >> they could have used a chisel. they could have used a crowbar. it would take them longer to get through than the steel because of the thickness of it. >> reporter: but even

then the escape wasn't over. crawling through that sewer pipe and using the tools again to cut through this manhole outside the prison walls. tonight, it's not just about finding these men but finding out how they did it. jeff rossen, nbc news new york. let's turn now to a story renewing the debate over police and the use of force. an officer on leave tonight after he was caught on camera forcing a teenage girl to the ground and pulling a gun as he tried to break up a pool party in the dallas suburbs. but some say the tape doesn't tell the whole tale. here's nbc's janet shamlian. >> reporter: police dispatch called it a disturbance at a community pool in the dallas suburb of mckinney. and what happened next has now been watched online more than 6 million times. mckinney police corporal pulling a 15-year-old bikini-clad girl to the ground. then pulling his gun on two other young people.

>> on your face! >> reporter: the seven-minute profanity-laced video was shot by brandon brooks. >> i did get frightened at one point when the officer had pulled his gun out on those kids. that was very scary and frightening. >> reporter: tonight there is outrage over the officer's actions. >> get down on the ground! >> i'm not indicting the entire police department because i saw some people doing the right thing. i saw officers actually trying to keep the matter right. this guy was just out of control. >> reporter: accounts vary of how it started. people who were there say the video doesn't reflect all that went on. >> the neighbors did not call the police because there was a big african-american party. security called police because there were fighting and people jumping over the fence and people and things of that nature. >> reporter: he says a few in the diverse and harmonious neighborhood defend the officer. >> the wrist lock and take to the ground.

we saw this officer getting out of control. there's no need for that. >> reporter: scott reits is a use of force expert formerly with the los angeles police department. >> we're not looking at a w-4 situation. you're looking at a bunch of teenagers at a pool party. >> on your face! >> reporter: tonight the officer is on administrative leave pending an internal investigation. corporal casebolt is 40 years old, he's a police academy instructor and he's been with the mckinney pd about ten years. tonight the neighborhood is expecting a march in protest of their actions. police say they'll be there but plan to hang back. lester? >> janet shamlian tonight. thank you. a south carolina police officer caught on tape fatally shooting a fleeing man in the back has been formally indicted for murder. officer michael schrager who has been fired from his department has been held without bail for the april 4th incident in which he shot waurltd scott after a foot chase. he told dispatchers scott had trabd for his tasers. authorities in boston today publicly revealed the surveillance video from the shooting of a

terror suspect accused of plotting to kill police. the grainy video is taken from a surveillance camera and shows last week's confrontation between usaamah rahim, fbi agents and a boston policeman. police say he drew a knife and came toward them and he oepd opened tire. the family says the video isn't clear enough to tell. authorities are investigating whether the shooting was justified. and firefighters are still on the scene of what was a massive inferno at a chemical plant in pennsylvania. explosions and heavy smoke billowing from the building overnight in hanover. residents up to a mile away asked to stay indoors, though emergency officials said the smoke is not toxic. thankfully no one was in the building at the time of the fire. president obama used his trip to the g-7 summit in germany to reaffirm the u.s. commitment to fighting isis. but as is often the case at gatherings of world leaders, some of the most memorable moments happened on the sidelines. our chief white house correspondent chris

jansing explains. >> reporter: he looked like the ultimate outsider trying to make his way in. iraqi prime minister haider al abadi eager to get president obama's attention. sit, standing, hovering. it looked like a snub. but looks were deceiving. abadi got what he came for. a promise of more help to defeat surprisingly resilient isis fighters. >> they're nimble and they're aggressive and they're opportunistic. >> reporter: the president ordering up a new plan from the pentagon to accelerate training and equipping iraqi forces. a shift in u.s. strategy that the president admits is still a work in progress. >> we don't yet have a complete strategy because it requires commitments on the part of iraqis as well. >> reporter: while abadi got what he wanted on another pressing issue so did president obama. the leaders declared a united front against russia for its continuing aggression in ukraine. and while that is the news of the day, this is the photo. the president and an

sources tell nbc news he was trying to cover up sexual misconduct with a male student. and there are new questions about how the former schoolteacher here would have raised the 3 1/2 million dollars in hush money. after humble beginnings a series of land deals made hastert a multimillionaire by the time he left congress in 2007. then he started working for a lobbying firm and disclosure reports show his clients paid the firm more than $11 million. but it was in 2010 the same year prosecutors say he agreed to pay an unnamed individual that hastert started to ramp up his lobbying. that's according to documents and e-mails in a separate lawsuit filed by an ex-business partner. that lawsuit was later dismissed. >> that's very -- youing the idea that you can have someone who was one of the most senior officials in the united states government trying to use their connections and influence to make as much money as quickly as possible. >> reporter: for 11 days he has not spoken.

we are back with health news that will be of particular interest to the 73 million americans who suffer from high cholesterol. think about that. that's one out of every three adults. this week an fda advisory panel is considering whether to recommend that the fda approve a new class of cholesterol-lowering drugs that some top cardiologists are calling a breakthrough in the fight against heart disease. next's tom costello has details. >> reporter: diane solhan is on the cutting edge of what doctors are calling a new frontier in fending off heart

little scientific debate about it at this nointd time. a high cholesterol level certainly raises the risk of heart disease including heart attacks. >> reporter: statins also lower the risk of stroke. but more than a million statin users experience debilitate debilitating muscle pain. so far the known side effects in this new drug are a small number of patients reporting confusion or memory loss. the biggest challenge could be the cost. by some early estimates, $10,000 per year. >> reporter: as for diane solhan her cholesterol is down and her quality of life -- >> i could run and play with my grandkids that before i couldn't. >> reporter: -- is pain-free. tom costello, nbc news washington. we're back in a moment with a shark attack in the waters off one of america's the world is filled with air. but for people with copd sometimes breathing air can be difficult. if you have copd, ask your doctor about once-daily anoro ellipta. it helps people with copd breathe better for a full 24hours. anoro ellipta is the first fda-approved product containing two long-acting bronchodilators in one inhaler.
