tonight on "nightline," ak-47, sniper rifles, they're some of the most powerful weapons in america. and yet, we got our hands on them in the time it would take to get a pizza delivery. tonight, we're undercover. and a medical mystery, waking up speaking swedish with no memory of your past, and suddenly taking on a foreign accent. tonight, what happens when your life seems lost in translation. and what killed cory? why did glee actor cory

from new york city, this is "nightline" with dan abrams. good evening, thank you for joining us, for many of us, owning a weapon is a constitutional right and one that many of us exercise proudly. but most law abiding gun owners may not think much about the ak-47s or the powerful sniper rifles, unless they're in the military. or they're criminals. so just how easy is it to get weapons? we found out. >> reporter: the u.s. is the most heavily armed nation in the world. and every day, guns fall into the wrong hands. >> he had a gun. >> reporter: we're going to try

to get guns the way a criminal might, avoiding background checks and finding sellers who don't ask too much questions. >> ready to rock and roll, baby. >> reporter: we turned to private investigator and firearms expert jesse torres for news about guns. if you are a rifle owner like jesse, what you're about to do at a private gun sale can be perfectly legal. >> $200? >> reporter: but jesse is also a former police officer, well versed in how criminals might go about obtaining weapons. for our first target we aim high, an ak-47, it is a weapon designed for war, used in battles and conflicts across the globe. and now we're about to get one using the internet. so if i wanted an ak-47, how soon could i get one? >> we should be able to get a

weapons transaction in 30 minutes. >> reporter: 30 minutes. >> and that is very easy with travel time, it is very easy to get a weapon here. i just punch in the word "ak-47," as the key words and we'll see what comes up. >> reporter: call and ask for nick. what do you think? >> we can certainly do that. >> reporter: so you don't think he is going to ask for anything? >> no, he just wants the money, you mentioned $750, he is on that. >> reporter: wow, that is just crazy. >> so we're good to go. >> reporter: we're good to go. hi, nick, i'm calling about the ak, is it still for sell? >> yes. >> reporter: i have 750 in cash, would you agree to that? >> yeah, we can do that. >> reporter: can we meet long? >> taco bell. >> reporter: taco bell, cool, nick, see you in a bit. >> this shirt is a little larger

than what i wore before, and i have a weapon. he wouldn't know that i'm armed. >> reporter: are these transactions safe? >> they have become less safe even for $650 or $700, people will kill you for that. >> so right now, we're following jesse and marianna. i'm nervous because these things turn into robberies. the fact that you know, you are going there and you know there is going to be an assault rifle. >> make sure it is hidden real well. >> reporter: so we're getting all wired. i'm geared up. i have my glasses on. they're already recording. >> anything goes wrong and we have a gs-w, gunshot wound. >> reporter: gs-w? >> right, a gunshot wound. >> reporter: you will call 911? now, i'm in a position i never

thought i would be in, heading to a fast food parking lot to make a cash deal for an assault rifle. should i call? >> yeah. >> reporter: hey, we're here, i didn't see the dodge, but i'm -- okay, good-bye. he is pulling in, in two minutes. >> this is a bad idea. >> i don't feel good about this, i'll take off, okay? >> reporter: okay, definitely. >> i'll be watching for somebody to rip us off, and we'll see. >> reporter: it is really scary waiting for someone to pull up, who you know has an ak-47. >> hi, how are you doing? >> reporter: hi. >> take a look at it -- thank you. this is good to go to me, 750? >> reporter: nick also has ar-15s, if we're interested. and are those for sale, as well? >> yeah.

also, it is a full sized one. >> why don't you feel it and see how this one feels to you? it is a little shorter and a little lighter, a little bit more maneuverable. so it has a laser mounted on it, too, and a flashlight. it is great. if you don't mind i'm going to think about this a little bit. thanks guys, appreciate it. talk to you a little later. >> reporter: could have left with three rifles today if we wanted? >> as i told you, we would have had three rifles in less than an hour, all of which are the military-style weapons. >> reporter: so this is what we just got. here is our ak-47, according to jesse, ready to shoot, right? came with a few rounds of ammunition. >> this is a typical russian round, it will penetrate all body armor, except for level 3 body armor and above. >> reporter: and all in the time it takes to order a pizza. if we lived closer, we could

have done this in five or ten minutes. >> right, and he wouldn't have had a trace of who i was. >> reporter: so how many times do you think this happens a day? >> all the time. >> reporter: if it is that easy to buy an ak-47 from a fast food parking lot, we need to aim even bigger. we're going to buy a sniper rifle, a weapon so powerful that the u.s. military uses it to penetrate concrete walls and pierce steel. it is a gun that could do an unthinkable amount of damage if it fell into the wrong hands. >> so from here, should be about three to five minutes to his house. >> reporter: we found someone who claims to be selling one in just a couple of minutes on line. >> how are you guys doing? thank you so much for meeting me. >> i'm mike. >> mike, i'm jesse. >> reporter: hi, how are you? >> just started to come down. so it looks like they're moving

into the garage. i can't see anything from here. >> this penetrates steel. and in iraq, the snipers don't waste one round on one person, even if he is standing behind a brick wall. usually have two or three guys lined up to shoot. because the brick wall, and all three of them. >> reporter: scary. >> this round right here, $15 apiece to fire this one. you get 11 boxes with 12 rounds apiece. so you have a lot of fire power to start your own war. >> reporter: what did he say? >> you have a lot of fire power to start your own war. >> reporter: wow, look at this. >> definitely not a lot of people have these weapons. >> reporter: by far, one of the

most powerful weapons out there that shoots the highest caliber. >> absolutely, the 50 bmg is definitely the top of the line. >> reporter: you were ready for war, he said. so it is a war gun. >> it is a war gun, all you need is a finger to pull the trigger. >> grab this handle and pull it back. >> reporter: within a couple of hours, we now own two of the most dangerous weapons in the world. oh, my gosh. no background checks. no waiting period. >> lock it down. >> reporter: no questions asked. >> wow! >> reporter: that was so powerful. for "nightline," in arizona. >> amazing, that all seems so easy, our thanks to marianna for that. keep in mind, private sales to individuals are not subject to the same requirements.

later this more you will be able to see marianna on "fusion," her report inside secret america airs tomorrow wednesday, july 17th on the national geographic channel. next, why did this american man wake up speaking swedish, and this woman suddenly develop a french accent. coming up. abc news "nightline" brought to you by "expedia." ople but a friend under water is something completely different. i met a turtle friend today so, you don't get that very often. it seemed like it was more than happy to have us in his home. so beautiful. avo: more travel. more options. more personal. whatever you're looking for expedia has more ways to help you find yours. geico's defensive driver,ke 13.

. our next story sounds so

incredible that your first instinct may be to try to confirm it is actually true. it is about a florida born man, his medical condition that left him speaking and writing only one language from a faraway l d land. and he is not the only one. >> reporter: a man is found passed out in a motel 6 in palm springs, california. an ambulance is called. he is rushed to the desert medical hospital. he is still alive. but at least his room contains his name, michael boatwright, age, 61, when he comes to, he opens his mouth and he can only speak one language, not english. the palm springs newspaper, "the desert sun," so far is the only newspaper to speak with him. [ speaking in a foreign language ] >> it is so unusual when you talk to them and they start to speak in another language. and then we try to ask them what

happened to them? where they were. who their friends and family are. and they have no idea whatsoever. >> reporter: and he was suddenly calling himself by a swedish name, which spelled out looks like this, johan ick, and his american past, gone, forgotten. >> it is puzzling, and people want to know what happened to this individual, as he wants to know. >> reporter: it is still very much of a mystery how the human brain works and how it manufactures memory and loses it. with the story of what michael boatwright is going through right now, certainly meeting the definition of mystery, boatwright has gotten on facebook and written up his own brief account of what he now knows about himself, facts dug up by a social worker in swedish. translated. they say i'm a very good tennis player, one of my hobbies is digital art. of course, he has that language,

not english. the question is, what is this? what it is not, is a condition reported on before, fas, foreign accent syndrome, something that this british woman, kay russell, developed after suffering a very bad migraine. >> my voice is deeper than it used to be, i know it sounds totally different than it used to be. >> reporter: hear that? this is how she sounded in a sales video a few years ago. >> hello, i would like to welcome you to the video. >> when i see that, i see the person i used to be. >> reporter: so this spontaneous accent she has is something she cannot control. >> it goes way beyond my voice. >> reporter: in michigan, this woman has the same trouble. >> i go grocery shopping and the clerk will say, you're not from around here? as a matter of fact, i am.

>> reporter: you were born here? >> i was born here. >> reporter: but this is susan speaking earlier on a tv program. >> when we get a chance to do the hands-on projects, the kids really enjoy it. >> this is the first time we did it, a year ago. >> reporter: doesn't sound like you? >> that is the real me. >> reporter: here is why fas doesn't match michael boatwright's symptoms. >> a foreign accent syndrome is peculiar, a situation where a person has had a form of brain damage, typically a stroke that affects parts of the brain that control speech. he has problems that seem to be involving things that are not directly related to memory, loss of ability to speak english. loss of a person sense of identity. these sound to be psychiatric. >> reporter: at least in boatwright's case, there some seem to be a possible sweden connection, a former wife who

was tracked down by sisters who were set to live in sweden. >> reporter: there was information where he called himself a swede, while he was still living in china. it is called brain injury, presumably, that is what michael boatwright suffered. how does he recover? >> typically, it lasts six or 12 hours. and then recovery is complete. >> reporter: in the meantime, what boatwright has written on facebook, again in swedish, again translated. i know that some day this will pass and i will remember everything. but for now, i have to take it one day at a time. thank you so much. for "nightline.." >> we still understand so little about the way our brains function and sometimes lead us astray. next, jodi arias intends to escape the death penalty. she is back in court. this is command center.er ] [ man ] 10, 9, 8, 7...
