good evening. thanks for joining us. tonight, new clues in the investigation into the worst

mass shooting in modern american history. the attack now showing signs of lengthy premeditation. authorities uncovering possible plans to stage similar assaults in other cities. and we are in las vegas tonight with grieving families wondering how to go on with their lives. here's abc's matt gutman. >> i would have given my life in a heartbeat and taken his place. >> reporter: for cameron robinson's family, the horrible reality is just starting to set in. >> part of my heart and soul feels like it's been ripped out, taken away. i'll never get that back. never get my brother back. >> reporter: four days after he was gunned down along with 57 other concertgoers, this is the view from above. when you look into those fairgrounds you see the evidence of that family-friendly festival, you see strollers and walkers. that las vegas fairground is still an active crime scene. right now there's still fbi forensics teams combing in groups through that fairgrounds.

they're trying to make sure they don't miss a single piece of evidence. >> go, now! run! >> reporter: that field became an indiscriminate killing ground. with the gunman firing from the 32nd floor of the mandalay bay across the street. >> everybody go! >> reporter: no one was safe. >> stay down, run this way! >> reporter: bullets raining down. in the aftermath, new video showing the chaos on the ground. that gunfire triggering hysteria, confusion. >> run, don't stop! run, don't look! >> reporter: police officers screaming to those concertgoers that they are under attack. >> everybody go! let's go! >> reporter: this video shot by ray page, who went to get his truck parked nearby, driving it back into the kill zone, turning it into a makeshift ambulance. >> right here, come in here! >> reporter: the wounded loaded in one after another. >> do we have any other wounded people to take? >> not right now.

>> reporter: ray jumps behind the wheel, drives down the strip, bringing them to paramedics. >> i got five wounded! gunshot wound in the chest here! >> reporter: law enforcement caf vaging for clues to how 64-year-old stephen paddock pulled off a mass killing of this magnitude. >> it's troublesome that this individual was able to move this amount of gear into a hotel room unassisted. >> reporter: at least ten bags stuffed with 23 guns and stockpiles of ammunition found in his mandalay bay hotel room. but how did no one notice? >> the sheer volume of them, you couldn't even shoot that many weapons. >> reporter: what's more, he may have planned to launch other attacks. law enforcement officials tell us paddock scoped out these two buildings to possibly rent a room just before the life is beautiful concert. they would have offered him the same type of field of fire right into the main stage and a crowd of people, tens of thousands who would have been absolutely penned in. police now say paddock may have also scoped out other cities,

possibly targeting fenway park in boston and the lollapalooza festival in chicago. as a result, police tactics across the country may need to adapt to this new kind of threat. >> i think what you're going to see is that if anybody else is going to have an outdoor concert that's in the proximity of buildings that are above the concert, they're going to have to put uniformed officers with sniper rifles on the roof. >> reporter: days into the investigation, the shooter's motive remains a mystery. but authorities have ruled out financial problems, and they hope paddock's live-in girlfriend, marylou danley, can provide answers despite repeated denials about knowing anything of his plans. danley was with paddock when he bought this ka are in reno, paying for this with this check of over $14,000. >> she said she had a bad relationship prior to him and he had turned her life around, really helped her out. >> reporter: the fbi asked

dealership employees about the purchase. >> marylou wanted to get a lexus. but he was like, i'm not going to spend $10,000 more for a car that's got the exact same equipment. >> reporter: over two weeks ago paddock sent danley to the philippines and wired her over $100,000, she says for a new house. authorities are also investigating his alleged contacts with a different woman shortly before his ram page. after each of these massacres, conversations about new gun regulations have been raised and then dropped. but today the political winds may be shifting. at issue, the bump stocks attached to the assault rifles used by the vegas gunman. these bump stocks allow the gun to be fired continuously, mimicking an automatic weapon. this video showing a bump stock in action. earlier this week, president trump said it wasn't the time to talk about gun control. >> mr. president, does america have a gun violence problem? >> we're not going to talk about

that today. >> reporter: but on capitol hill, republican congressman carlos carvelle from florida plans to introduce bipartisan legislation banning bump stocks. >> the goal is to prohibit these deadly devices that caused so much death and destruction in las vegas earlier this week. most members on both sides of the aisle agree that this is a blatant circum vention of the law and we want to close this loophole. >> this has the potential to be a major moment. no gun legislation of note has passed in decades in congress. the fact that you have bipartisan interest, and even minimal changes to the nation's gun laws, that registers as a big deal even if it's nowhere near gun control advocates' dreams. >> reporter: the president of the national rifle association says it's worth reviewing bump stocks' legality. >> the nra has said, we ought to take a look at that, see if it's in compliance with federal law, and it's worthy of additional regulation. that being said, we didn't

saban, we didn't say confiscate. >> reporter: even president trump may be changing his tune. >> we'll be looking into that over the next short period of time. >> this issue has come to the forefront. and there's no avoiding it for the white house. and that's why you see the white house now saying they want to be part of this conversation, they want to engage in the conversation. >> reporter: this latest massacre all too familiar for families who have lost loved ones in similar horrors. they've come to las vegas to provide support. >> if you were there at the shooting -- >> you're traumatized. >> i don't care if you were hit, i don't care if you lost a loved one, if you were there, you still were traumatized. >> reporter: lonny and sandy phillips lost their daughter, jessica, in the 2012 aurora, colorado, movie theater shooting. >> you look at those numbers and you know what some other mother is feeling at that very moment. and you have walked in those steps. you know what another father is feeling, a brother. children.

who lost their mother and can't possibly wrap their brains around what has happened. and then you get angry. and then you take a deep breath and you go to work. >> reporter: that's what they did, banding together under the name survivors empowered, and offering empathy to victims' families. >> we tell them up front that we're not here to provide any kind of mental health services to you, we're here just mother to mother, father to father, sister to sister, and help you through that initial shock of what you're experiencing now about and what you're going to be experiencing the next few months. >> reporter: around the country others are looking for ways to pitch in. the las vegas victims fund has raised more than $9 million in just three days. but it will take more than money to heal the wounds here. for "nightline," i'm matt gutman in las vegas. >> indeed. and "20/20" will air a special

he had a hit show about nothing. and an act about nothing. but his life has added up to a whole lot of something. standup comedy has been jerry

seinfeld's obsession for more than 40 years. tonight he tells gma anchor george stephanopoulos why he keeps coming back to the stage. >> please hurry up and finish laughing, i've got a lot more i've got to do here. >> reporter: before he was getting coffee with comedians -- >> you've finally done a show about nothing. >> reporter: before one of the most successful sitcoms ever. >> it's about nothing. >> yada yada ought to be the best part. >> i mentioned the bicycle. >> reporter: before he was married with three kids of his own, jerry seinfeld was a long island kid trying to make it in comedy. >> it was like my gay closet moment where i had to say, mom, dad, i'm -- i don't know how to tell you dthis -- i'm a funny person. >> reporter: his new netflix special goes back to the beginning. you went back to your original standup routines. and is it true you actually had to relearn some of the jokes? >> all of them. i was surprised too. there's a little joke in there about the cotton balls.

>> i go to the doctor, before he gives you the shot, puts the alcohol on your arm with the cotton ball. i bring one of mine, maybe you could use this one. >> it was a great laugh. i couldn't find the funny. why was it funny? it was a certain timing. there's a -- like a move with your hand. there's a look on your face. all those things have to be there or it doesn't work. >> it's not just what's on the paper? >> no, no, that's 2% of it. 98% is the way you do it. >> so i could read one of your jokes and if it's -- >> probably not going to work, no. >> reporter: jerry before seinfeld is the first of two comedy special forth netflix, part of a mega deal that made headlines when it was announced last january. >> i'm left-handed. left-handed people do not like that the word left is often associated with negative things. two left feet. left-handed compliment. >> one of the thing wet see, your first joke. >> my first joke. being left-handed.

>> left-handed. >> what are we having for dinner? leftovers. go to a party, there's nobody there, everybody left. >> first performance and that joke got applause. and i just froze. because i didn't know what that was. and that was it. that was -- the sun just hitting you in the eye. you go, that's it. i'm never doing anything else. >> no other jobs? >> no, i'm doing this. i don't care. i don't even care if i'm successful. i'm doing this. i love it so much. >> and you were so good at it. never a moment where you thought it might not happen? >> oh, yeah, lots of moments like that. lots of them. >> you must have known something, though. it's one of the most amazing things in the special. we see all of the yellow pads. you've saved every successful joke? >> george, what else did i have? >> i don't know. >> nothing. a couple of people hive asked,

why did you save it? what else would you save? what else? i don't have jewels. i don't have nice clothes. but the material. the hardest thing in all of entertainment is to write standup comedy. it is harder than anything else. >> after years of performing in clubs, seinfeld finally made on it "johnny carson." >> who designed pajamas, why do they make them look like a tiny suit? >> imagine nbc, you have a kid going on "the tonight show" with carson and late night with letterman three, four times a year, both shows. they never once went, maybe we should talk with this young man. >> come on. >> no. nothing. they never talked with me. >> you never pitched to them? >> no. >> how come? >> they were doing "alf." they were doing "cheers." >> of course nbc did finally give seinfeld a shot and a series. and almost 20 years after the

finale, it's still seen all over the world. so what happens when you're at home? it's hard to miss sometimes, if you're just clicking. do you stop -- >> no, i can't. >> can't touch it? >> maybe like two lines, then i got to go. my daughter to annoy me last night was playing the theme song of the show. >> that's kind of mean. >> yeah, she wanted me to come in her room to talk, i said you come in our room to talk. and we were having a fight about that. who would go into whose room? so to get me, she blasted the theme song of the show. >> and you went to her room, of course you did. and more than 40 years after his comedy career first began, he still loves the work and the rush. tell us how it happens. you have an office. >> i still do the same exact thing. >> you put the pad down -- >> same pad, bic pen, clear barrel, blue. and just wait. i don't just wait, because i have things i want to talk

about. like i want to talk about when you're texting. the three ghostie dots. why are we so anxious? as if before the phone rang it went "brr." >> you tried all these different things but you always go back to the standup. >> i was like a raccoon to my parents. you know there's one around, but no one's tracking the actual whereabouts. >> that's just the meat and potatoes. >> i don't like that analogy. i would say -- it's the heaviest drug. >> wow. >> i would describe it as the heaviest drug. >> it's not just sustenance, it's euphoria? >> no, no, it's the rush. there's no rush. in these other things. there's satisfaction. there's accomplishment. but that mainline "whoa" rush. >> friday night in kansas city. saturday in toledo -- >> doesn't matter. no one ever said that before.

and i just said it. and they just liked it. boom. >> now that's an addiction. our thanks to george stephanopoulos. "jerry before seinfeld" is currently on netflix. up next, the nfl star who crossed the line and not in a good way. baa baa black sheep, have you any wool? no sir, no sir, some nincompoop stole all my wool sweaters, smart tv and gaming system. luckily, the geico insurance agency recently helped baa baa with renters insurance. everything stolen was replaced. and the hooligan who lives down the lane was caught selling the stolen goods online. visit geico.com and see how easy it is to switch and save on renters insurance. i had this chest cold, but my medicine kept wearing off. (coughah! i missed you!

then i discovered mucinex. one pill lasts 12 hours,and i'm good. why take 4-hour medicine? one mucinex lasts 12 hours. let's end this. when you're close to the people you love, does psoriasis ever get in the way of a touching moment? if you have moderate to severe psoriasis, you can embrace the chance of completely clear skin with taltz. taltz is proven to give you a chance at completely clear skin. with taltz, up to 90% of patients had a significant improvement of their psoriasis plaques. in fact, 4 out of 10 even achieved completely clear skin. do not use if you are allergic to taltz. before starting you should be checked for tuberculosis. taltz may increase your risk of infections and lower your ability to fight them. tell your doctor if you are being treated for an infection or have symptoms. or if you have received a vaccine or plan to. inflammatory bowel disease can happen with taltz. including worsening of symptoms. serious allergic reactions can occur.

now's your chance at completely clear skin. just ask your doctor about taltz. now's your chance at complepoallergies?reather. stuffy nose? can't sleep? take that. a breathe right nasal strip instantly opens your nose up to 38% more than allergy medicine alone. shut your mouth and say goodnight, mouthbreathers. breathe right.
