- yeah, right. hi to you too. like i was about to say, there were two sets of prints on jamie hallen's car. claire's and a matt duggan's. he got killed-- - in an explosion yesterday. jamie hallen crashed on roosevelt drive? - thought that was supposed to be hushed. - car crash must be where they got the money, finch. - jeez, anything you don't know? - yeah. how's carter doing? - she's hanging in there, you know? but it's hard to do the job when you're stuck on your desk. - we'll keep an eye on her, make sure she's okay. and detective, leave your phone on when you talk to congressman hallen. - you can hear me all the time? - yes, and i'm hearing rather too much of your lower intestine. could you possibly move your phone from your belt to your jacket pocket? - hey, fusco, you die in there? - keep your panties on, i'm coming. - if there's anything i can do, please call me. - thank you, davis. thank you very much. - and again, deepest sympathies for your loss, congressman. - appreciate it. thank you.

detectives olson and fiasco. - fusco. - why--why are you here? i already talked to one of your people about jamie's accident. - we have further questions about the accident, sir. it may relate to another case. do you know your son's movements that night? - he was at a party at davis bannerman's house. he, uh, was driving home when he was...killed. - you're investigating bannerman's bank, and your son socializes with him? - i didn't like it either, but i couldn't control my son's social life. - you son have a lot of money on him that night? - i have no idea. why would that be pertinent? - two people were murdered. we think they were both at the crash site. we also think they found money in the car. - i'm sorry. i don't know what to say. - was he dealing drugs? - [sighs] look, he's dead. can't we just let it go at that? - two other people are dead too. so, no.

- i worried that he--he-- he was doing something he shouldn't be doing. he was dealing with people he shouldn't have been dealing with. that's all i can say about it. - well, we'll have to talk to bannerman. - as long as you take what he says to you with a grain of salt. we're not friends. - one of these were found in your son's car. did he set up this charity? - yes, he did. that's how i like to think of him. his good deeds. - you left bannerman's house, but you weren't going home, were you, jamie?

- here is your new phone, okay? - thanks. did you say anything to mom? - not till i know that we're safe. did you hear about that guy matt? there's people looking for us. okay? you get back, or i will shoot you. [gun clicks] - if you're going to buy a gun... [gun clicks, cartridge clatters] make sure you know how to use it. - you came to the salon. what do you want? - you mean apart from a haircut?

how do you two know each other? - we've known each other for years. we're foster sisters. not that that's any of your business. - guess the, uh, money you took from the crashed car is none of my business either? - we're not telling you anything, till we know who you are and why you're following us. [knocking on door] - hello! anyone at home? - find out what he wants. and stand away from the door. - who is it? - uh, my name is dayne. i'm sorry to trouble you, but my car has just broken down. - i'm sorry, but this isn't a garage. - [laughs] i know, i know, but the thing is-- is my phone just died and the kids are getting kind of scared, so if i could just use your phone? i--i'll pay for the call. - let him in. - all right.

[gunshots, glass shattering] [tires squeal] huh, fifteen minutes could save you fifteen percent or more on car insurance. yeah, everybody knows that. well, did you know that playing cards with kenny rogers gets old pretty fast? you got to know when to hold'em. know when to fold 'em. know when to walk away. know when to run. you never count your money, when you're sitting at the ta... what? you get it? i get the gist, yeah. geico. fifteen minutes could save you fifteen percent

- re how jamie hallen died. - ooh. - ugh. i persuaded a tech at the real time crime center to copy this for me. two cars stopped after the crash. crime center guys were able to read the plates. prius registered to claire ryan, escort to matt duggan, so they're confirmed. but look at this. - two more women. - mm-hmm. - crime center identify them? - nope. camera's set for maximum field of view. resolution's not enough for facial recognition. this is where it gets interesting. - suitcase. that has to be the money. we got to find these girls before the killers do. - guy at the crime center said there's another detective looking for them. detective foster, 82nd precinct. - we got anything else? - yeah. this guy. about 30 minutes after the crash, he makes a phone call.

- unfortunately, we're not the nsa. vehicle must be new, 'cause look. there are no plates. - that's convenient. want to get in some more trouble, carter? go talk to detective foster, and see if he knows anything. - be a pleasure. - finch, can you do a search for susan mcnally at st. george's hospital? - i'm on it. everything all right? - killers just tried to take out wendy and paula. - please tell me they failed. - for now. girls took off. they're sisters, finch. foster sisters. if their mom's still at st. george's, that's where i think they'll go.

that why the girls took the money? - had a fall, broke her hip. not sick exactly. her home is the problem. mortgage is worth more than the house. bank's foreclosing on her. - at least they took the money for a reason. you know whose it is yet? - i'm digging. keep those girls safe. - fusco, carter. just left the 82nd. there is no detective foster. somebody used a fake detective shield to get eyes on the crash footage. [car horns honking] remember how claire was beaten up? i think the killer tracked her through her license plates, then tortured her to get the other names. call me. what's wrong with you, following a cop? trying to get yourself shot? - i'm just worried about you, detective. - don't. just back off, okay? you and your preppy friend over there.

- you're cia. i met plenty like you in the green zone. so why are you worried about me? - because of the man you're chasing. he's dangerous. - he saved my life. what was that, an accident? - no. just proves he still has good instincts. - do you even know him? - yeah. i was his best friend. - then why do you want him so bad? - because he used to kill people for his country. now he just kills them. his victims... the ones that we know of. for some he deserves a medal. for some, the chair. - why are you telling me this? - 'cause we want you to know who he is. he's an incredibly dangerous, incredibly gifted man who's been almost destroyed by the things he was made to do. he's always looking for someone to trust, but his paranoia makes trust impossible. - i don't understand. - kara stanton-- his cia handler. they were a team.

a dozen times, and then-- - he killed her. then disappeared. we thought he was dead. gave him his star on the wall at langley. then three months ago, you ran his prints-- brought him back from the dead. - we want to bring him back in before he kills anyone else. before he kills himself. we want to help him. - so where do i come in to all of this? - we think he trusts you. like he trusted her. we want you to keep yourself, and him, alive. - thanks for coming in, mr. bannerman. - anything for the nypd. - jamie hallen-- he was at a party at your house, two nights ago. - briefly. he was stoned. i asked him to leave. even ordered a cab for him.

- was he dealing drugs? - look, i liked the kid. but i don't want to-- - was he dealing drugs? - i don't know. but he seemed to have a lot of money suddenly. and, uh, let's put it like this. i heard he was dealing with some people he shouldn't. - i heard, detective fusco. bannerman's story confirmed congressman hallen's. - yeah, he said the same things. - so it doesn't help us. - you're not hearing me. he said the same thing as hallen. look, i interrogate a lot of douches, and i know when they got their lies lined up. - they coordinated their stories? - despite the fact they're supposed to hate each other? i think bannerman was working something with hallen. jamie was a go-between, and now they're tossing him under the bus. - mr. reese?

wendy's here. no sign of paula. what do you got? - getting close. i know where jamie was going that night anyway. only as far as laguardia airport. - was he flying somewhere? - yes. on a jet belonging to davis bannerman. flight plan to the caymans filed with the faa. jamie hallen the only passenger on the manifest. - excuse me, can i help you? are you looking for someone? - just found him. thanks. why was he going to the caymans? - i believe he was working for his haitian orphans charity. a theory i'm about to put to the test. i'll call you. - where's paula?

- she's gone to get something to eat. we were worried about you. - wasn't me they were trying to kill. - i'm sorry we lied to you before. - you were at the crash scene. want to tell me what happened? - we were out walking. the car crashed almost in front of us. we ran up, found two people there already... trying to help. the, uh-- the driver was dead-- coke all over him. and a suitcase with, like, a million bucks in it. young guy, fast car, cocaine, cash. i mean, the money had to be illegal. - so you took it. - we divvied it up... 250 grand each. would have fixed everything. it was wrong. we knew it was wrong.

called 911, and walked away. - where's the money? - it's under mom's bed in there. the nurses think it's her knitting. $1/2 million worth of knitting. - [muted cries] - whoa, whoa. - what do you want to do? - we want to give the money back. but we don't know who these guys are. drug dealers? mafia? - and your mom? her house? - we'll find a way... somehow. [cell phone rings] oh, that's paula. - just sent you a picture. i want you to get the money and come down to the third floor of the parking garage. come alone-- no muscle--

aleve pm. the only one to combine a safe sleep aid... plus the 12 hour pain relieving strength of aleve. be a morning person again with aleve pm. - found him. he's dead. the money's gone. we got cameras. might need some help. - mr. hallen, this is thomas paine. - congressman, thank you for seeing me on such short notice. - always a pleasure to meet a representative of the blogosphere. have a seat. that's a rather famous name. - nom de plume. sir, your enemies are trying to bring you down. and they're using your son to do it. - they used jamie? how? - blackmail.

you know about his haitian orphans charity. - yes, i hope it will be his legacy. - i hope it won't. they have $30 million in that account, and they've never helped a single child. it's a classic black-arts setup. they open an offshore account-- - who are they, for god's sake? - the banks, of course. bannerman and his ilk. they stuff it with money, they tie you to it by association, and then they expose it and ruin you. the man who's supposed to bring honesty to wall street is shown to be as corrupt as those he's investigating. - have you taken this to the police? - no, no, no. they're in the pocket of wall street. i'm offering you a chance to extricate yourself. as your son's executor, you could close that charity, transfer those funds to the red cross. and then what would your enemies have on you? nothing. you'd be clean. and all of their dirty money would have gone to a good cause.

- i will. do you have a contact number? - it's written on this... my plume de nom rather than nom de plume. - indeed, mr. paine. i'm deep in your debt. [phone rings] - davis bannerman. - davis, this is jim hallen. before you ask me how i am, i'm not well. not only is my son dead, but his damn accident is threatening to put us both in jail. - my people are on top of it. the last two items are about to be dealt with, so relax. - i can't! some idiot blogger found out about the cayman charities. - what? how? - how do i know? we've got to shut it down, move the money. but first, you've got to close up the leak. - no problem. how do we find him? - fusco. - detective fusco. i'm sending you a recording. [phone rings] - carter.

- maybe. maybe you can come in here, help me explain some things. - no, thanks. but i can help you look good in another way. - oh, yeah? - the people who killed claire ryan and matt duggan-- parking garage, st. george's hospital. - when's it going down? - i have to go. - wait. thank you... for saving my life. - you're welcome. [dial tone] - [sighs]

- snow. - he just called. i know where he's going to be. - call the number. tell him he doesn't see you or the money until you see paula. - i'm here. but i'm not going to do a thing until i can see that paula's safe. - [over phone] okay. - paula's okay. you're going to walk towards her. if i shout, you run.

okay? go. - you again? have you lost your car? - i'm waiting for someone. - okay. good night then. - wendy, paula, run! run, paula! - [groaning] ah! - i thought you were nice.

- are you okay? - will you take this? - no. you earned it. no one's coming after you anyway, not now. but you should go quickly. - thank you. for saving my life. - you're welcome. [computer keys click] - he just called. i know where he's going to be. - you got the cameras?

- you laid it on the line in shadows where you hide a life that was designed you've been cheated, oh, so blind - hello, john. - mark. - glad to see you're still alive. - i bet you are. - surprised you ended up in new york city. thought you'd get yourself a cabin in the woods-- montana, maybe. - what do you want, mark? - time to come home, john. slate's been wiped clean. - you know that will never happen.

- these twisted words of time and how your spirit shines i wish that you were mine - you see him? - negative. - get down here and find him. carter! damn it! - i know that i've been falling [tires squeal] - hey, harold. - john, i've been trying to call you. - yeah, i've been kind of busy. - where are you? - parking structure. it's not looking good. - carter sold you out. they got to her. - yeah, they're clever like that. i wanted to say thank you, harold, for giving me a second chance. - it's not over, john.

- no. you stay away. don't even risk it. [engine revs] [tires screech] - into this endless night [tires squeal] - [grunting] - i know that i've been falling - hold it! you? get him out of here.

i'm billy, and i quit smoking with chantix. i don't know that i can put into words how happy i was when i quit. it's like losing some baggage, i don't have to carry it around with me anymore. chantix made it possible for me to quit smoking. along with support, chantix (varenicline) is proven to help people quit smoking. chantix definitely helped reduce my urge to smoke. some people had changes in behavior, thinking or mood, hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. some had seizures while taking chantix. if you have any of these, stop chantix and call your doctor right away.

tell your doctor about any history of mental health problems, which could get worse or of seizures. don't take chantix if you've had a serious allergic or skin reaction to it. if you have these, stop chantix and call your doctor right away as some can be life-threatening. tell your doctor if you have heart or blood vessel problems, or develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke. decrease alcohol use while taking chantix. use caution when driving or operating machinery. most common side effect is nausea. man, i love being a non-smoker.

i see something that shouldn't exist here. i see this monster wall of ice and i see it coming at us. i just yelled down! it was the most terrifying moment of my life. >> it was supposed to be the adventure of a lifetime. >> the ultimate mountaineer's

challenge. >> a team conquering mount everest, the highest summit on earth. >> have a safe trek. >> you're at 20,000 feet. you're trying to breathe. >> they were prepared for towering dangers of everest. but no one that day was prepared for this. >> all of a sudden, the ground starts to shake. it's a whiteout. i thought, "this is it. i'm done." >> we just hear the most awful noise. an incredible, thunderous roar. >> reporter: it must have seemed like the end of the world. >> unthinkable. a bad dream. everything's been completely destroyed. >> i didn't expect to survive. >> you're not in control, the mountain is in control. >> oh, dear, my lord. >> i'm lester holt, and this is "dateline."

everest -- "avalanche!" >> reporter: even amid the majestic himalayas, it dwarfs everything around it. >> it's almost indescribable. it's breathtaking. >> reporter: mount everest, the highest mountain on earth, is, for many climbers, the ultimate challenge. >> once you've had a taste of it, you just -- you can't stop until you've conquered it. >> reporter: a famous climber once said, "you climb mount everest because it's there." but that climber, george mallory, died on everest in 1924. the mountain's history is long and deadly. >> you just gotta deal with nature. it always got the upper hand. you can't fight nature. if you fight it, you will die. >> reporter: and when disaster strikes here, it takes a while for the outside world to realize it. with the aftershocks still coming, people here understandably don't want to

spend the night in their homes. >> in april 2015, we travelled to nepal to cover the 7.8 magnitude earthquake thatd llions homeless and devastated one of the world's poorest nations. then, when we saw these pictures of the destruction at everest base camp caused by an avalanche after the earthquake, we headed up to find out what happened to the hundreds of people living there in tents. our story begins three weeks earlier, when a group of climbers landed here, at an airport many believe to be the most dangerous in the world. haley ercanbrack was one of them. >> it's a scary place to fly into. it's one little landing strip. and then when you land, it's gotta be perfect. >> reporter: haley had traveled from arizona, where she runs beauty salons. >> i've dedicated the last three years of my life to climbing mountains to fulfill this dream of summiting mount everest.

father, randall, a successful cherry farmer with the beard he likes to think makes him look like a pirate. the two are very close, and have climbed together all over the world. it's their father-daughter bonding. >> he's given me many opportunities in my life to, you know, spread my wings and fly. he's been very supportive. >> reporter: haley and her dad had joined an expedition led by garrett madison. he's a seattle based mountain guide, world class. he's summited everest six times. >> i was really excited to return to everest. i had a big team. 14 climbers. and going into it, the vibe was really good. >> reporter: so tell me about the group. >> i had climbers from six continents. all people i'd climbed with on in the past on other peaks, some on everest, some on peaks in antarctica, south america, europe. >> reporter: garrett's clients had paid as much as $70,000 each

training for years for this, their trip of a lifetime. >> i instantly got along with everyone. >> reporter: as the group erest, haley wasgrowing especially close to eve girawong, a 28-year-old physician's assistant from new jersey. she was the expedition's doctor. >> gorgeous and friendly and helpful. and she was our caretaker, you know, she wanted to do everything for you and make sure you were feeling well. >> a little bit of arthritis. >> reporter: eve was trained in wilderness medicine, and she had a secret. >> they kind of kept that from us. >> reporter: but it wasn't a particularly well-kept secret. eve and garret madison, the team leader, were in love. >> it was quite obvious that they were together. i thought it was great. they sort of played it down. >> reporter: he was trying to keep his personal life and professional life a little -- a little discreet? >> exactly. >> i'm getting my ass kicked by

the altitude, but it's all good. deep breaths and look at the view behind me. if i'm going to suck wind, this is where i'm going to do it. >> reporter: the expedition was being documented by filmmaker michael churton. nbc news licensed his footage. >> our joke was you're the lonely cameraman. so you're kind of isolated, you know, a lot. >> reporter: you're the wedding photographer, you're not the bride or groom? >> that's right. >> reporter: churton is no stranger to the mountain. he was with another expedition in the spring in 2014 that was cancelled after 16 shurpa guides were tragically killed in the avalanche in the treacherous kumba ice fall. >> i came there to do something great, to be part of something great. and it didn't happen. and that may probably have, like, planted a seed, you know, to come back this year. >> reporter: michael, who was not an experienced climber, was only planning to hike as far as base camp. so was a young brazilian trekker named davi. >> the views are simple amazing. >> reporter: 69-year-old ron nissen hoped to become the oldest australian man to summit everest.

this camera, so i keep on saying nasty things knowing he won't ever be able to use them in the film., the team was accompanied by sherpas, local people famous for their ability to carry heavy loads of water, food, oxygen and other supplies up the steep mountains. the truth is, with climbing everest. about halfway up to base camp, haley got her first view of the mountain. >> you can see the top of everest right here, which is absolutely incredible. the ultimate mountaineer's challenge, so you know, it's pretty cool. >> reporter: there was also another, much more somber, stop on the way up to base camp. >> we passed by the memorials to the fallen climbers on everest. >> reporter: more than 250 people have died trying to summit everest. garrett wanted to make sure his team always kept that in mind. >> whenever i stop there, i think about those climbers who were in the same situation we

and i always think, "this is important for us to stop, to think about how serious this climb is." >> reporter: it certainly wasn't lost on haley or her father. >> it's actually a little creepy to be here, i'm not gonna lie, looking at all these memorials. and it definitely is in my mind that, holy crap, i'm doing this and you know, the dangers of it and it's crazy. >> it's a tough deal because you're trying to protect your lovely, beautiful daughter, and that's why i'm here. maybe i'm older, and maybe i'll something or feel something she doesn't. you know, it's a scary thing. but she's brave and i'm brave, and so we'll be good, we'll make it. >> reporter: nine days in, they finally reached their first goal, base camp, at the foot of mount everest.

this is base camp. after the arduous trek up the valley, the madison group climbers settled into their tents. physically and mentally, their main focus was this, the khumbhu icefall, a frozen obstacle course they'd have to navigate their way through. the icefall is the most dangerous part of the ascent up everest. what they had no way of knowing that this time, the real danger was lurking high above them on the peak of an adjacent mountain called pumori. blissfully unaware of the danger to come, the group began a week of training to prepare for the ascent to the summit. they never suspected that the mountains were preparing to unleash their wrath once again. what was next for them on that mountain? when we come back -- >> we set out about 2:00 a.m. >> up before dawn to start the journey up everest. >> a safe trek. >> danger would be quick to

ice, and i see it coming at us. phil! oh no... (under his breath) hey man! hey peter. (unenthusiastic) oh... ha ha ha! joanne? is that you? it's me... you don't look a day over 70. am i right? jingle jingle. if you're peter pan, you stay young forever. it's what you do. if you want to save fifteen percent or more on car insurance, you switch to geico. you make me feel so young... it's what you do. you make me feel so spring has sprung. i know blowdrying fries my hair, but i'm never gonna stop. because now i've got pantene shampoo and conditioner the pro-v formula locks moisture inside my hair and the damage from 100 blow-dries is gone. pantene. strong is beautiful. i will take beauty into my own hands. olay regenerist. it regenerates surface cells. new skin is revealed in only 5 days. without drastic measures. stunningly youthful. award-winning skin.

from the world's #1.

test . >> they had settled in at mount everest base camp and begun the hard work of preparing to

summit. >> i like going uphill. so it is good. >> going to find the sweet spot. >> they spent a week of last minute training on the hauntingly beautiful ice bowl. >> my 9:30 marching out on to the the glacier. >> leaving base camp and traversing the ice fall would be the first step towards the summit. the climbers would ascend to camp one around 20,000 feet and on to camp three and camp four at 26,300 feet. the last push through the so-called dead zone would take them to the summit. 29,029 feet. with all that ahead of them, the climbers were training hard and resting hard at base camp. haley was having the time of her

you like it like this? oh, thank you. >> base camp is sort of like your home base -- the safe haven. it was very warm. i felt safe there. >> reporter: decent accommodations? >> absolutely. we watch movies every night. shh, don't tell the people at home about it. >> reporter: for some of the climbers, including haley's dad, there was even time for haircuts. >> probably should be a little longer than this, but he's old just kidding. >> thank you. >> but comfortable as base camp was, the rigorous training, foreign food and water and high altitude were taking a toll. haley got too sick to train one day. she jokingly blamed her dad. >> i got a little flu going on, achy, chills, sweats. i'm not happy about it. just fluish. >> she gave it to me, by the way. >> no, you gave it to me. stay

you gave it to me i'm sure. >> the doctor's in. >> reporter: expedition doc eve had her hands full, so she set up shop. >> so here, i've just got equipped with a lot of basic supplies, medications. i can do vitals and just check your temperature just give them a proper physical examination. >> reporter: ron, the older australian climber, got sick after drinking some improperly treated water. eve even acted as randall's dentist when he chipped a tooth. >> now i'm going to make the paste. >> i suddenly hit the hard nut. broke a little piece of my tooth off in the back on a molar. >> we're going to try and fill it in the best we can. it's kind of a durable filling i've got, um, it should last us these next seven weeks. >> gotta have a hug from the doctor. >> reporter: the sherpas had constructed a traditional altar. shortly before heading out for the summit, the whole team

of two holy men. >> we just had two lamas come up and conduct the ceremony over the last three hours, asking the mountain for safe passage for all of our team. >> reporter: you do this ceremony, then the climb begins? >> i felt everybody was competent, proficient, had reviewed their technical skills, were ready to go. >> reporter: with everest expeditions getting more and more popular and only one route up the mountain, garret wanted to avoid getting stuck in a traffic jam. >> we set out about 2:00 a.m. to try to beat some of the crowds. you wanna be able to move as quickly as you possibly can through the khumbu icefall. >> i feel like a million bucks. >> reporter: it was now time to climb mount everest. as they geared up in the predawn darkness of april 24th, the climbers who were heading out for the summit said good-bye to the team members who were staying back at base camp. ron, the australian, still sick with a stomach bug, davi, the
