this morning on "world news now." as one survivor put it, it was literally running for your life. new details now emerging from the mass shooting in las vegas, from those who ran from the terror, the officers who ran toward the shooter and the arsenal of weapons, as police investigate his past for a possible motive. plus, we'll look at how the world is reacting to this tragedy on this tuesday, october 3rd. from abc news, this is "world news now." we do say good morning on this tuesday. we're going to get right to it. in las vegas, the entire country, and the world for that matter, mourning the worst mass shooting in modern american hi

>> so here's what it looks like now on the vegas strip. this is more than 24 hours after the deadly rampage at a country music concert. several candlelight vigils were held across the city last night for the 59 killed and more than 500 injured. >> the city has a broken heart, but they will not be damaged by one human being. you see ecveryone coming together. abc's matt gutman has more on the massacre. >> reporter: the chaos unfolding in the heart of the las vegas strip. 10:08:00 p.m., 28,000 gathered for the concert. 64-year-old stephen paddock was watching. he hammered throughout windows and started firing on the crowd below. jason aldean was on stage with automatic gunfire quickly drowning out his voice.

music stops. and he runs off stage. the audience huddling on the ground. the mandalay looming over them, for so many, confusion was part of the show. >> that's just a firecracker. >> reporter: seconds later, the rapid-fire shooting starts again. terrified people pile on top of each other, sheltering behind anything think could. but they were in an open field, easy targets for the gunman in the tower. >> i don't now where to go, oh, my god! >> reporter: thousands looking for safety anywhere, even a stranger's car. >> get in!

>> relax, relax! >> my husband and i ran out toward our car. and there were people hiding underneath my car for cover. >> reporter: we found mike cronk, head and hands still stained with his friend's blood. mike had used his shirt to keep his friend from bleeding out. you guys were trying to do triage while the shooting was still going on. >> yeah, everybody was jumping over the fences and there was no way i was leaving my buddy. we had to keep compression on the thing. we weren't sure the shooting was stopped. but we got him over the fence and under the stage. so at least we knew he was safe. >> reporter: as an army of police descended, s.w.a.t. teams are closing in on the shooter. they approach his door with an explosive. >> everyone in the hallway needs to move back, all units move back. >> breach, breach, breach. >> reporter: police say they

found paddock dead inside. i had killed himself. >> right now we need your truck. we just need to get people to the hospital, okay? >> reporter: down on the ground, the sidewalk a triage center. the wounded carried on barricades turned into stretchers. even in wheelbarrows. >> we just saw a bunch of people who needed help. so we just started piling them in the truck. >> reporter: total lockdown. the american playground now a killing field. >> matt, thank you. we're getting new details now, about the lethal arsenal amassed by the killer. >> wrap your head around this for a moment. police say the shooter had 42 guns all together. some of them believed to be fully automatic. 23 of those guns were right there at the mandalay bay inside of his hotel room. another 19 firearms were found in his home. >> officers are searching his home in nevada hoping to find a motive. >> reporter: s.w.a.t. teams and police descended on the small

the home of stephen paddock. his neighbors in disbelief. >> just in shock and shaking. i can't believe someone in here would do that. i just can't believe it. >> reporter: police raided his homes in reno and mesquite, where they used a robot to take out the garage door. they found 18 weapons and thousands of rounds of ammunition in the home he shared with his girlfriend, marilou danley. >> we've seen them leave the house together. yeah. yeah. >> reporter: and nothing seemed out of normal? >> no. did they get into an argument that would cause him to think about doing that? >> reporter: 2300 miles away in florida, stephen paddock's family is also struggling to understand how he could commit such carnage. >> there's absolutely no way i can conceive my brother would shoot a bunch of people. >> reporter: his brother says he

there was no mental illness and no warning. >> he doesn't even have parking tickets. no record of any affiliations. nothing. >> reporter: the last time they spoke, just weeks ago right after hurricane irma hit florida. >> the last time i communicated with my brother, he texted me and said "how's mom." i texted him back. >> reporter: paddock says he moved his brother to this quiet retirement community nearly two years ago. and stephen was a wealthy gambler. >> he didn't hunt, he barely shot his guns, ever. he had a couple of handguns that he kept in a safe. >> reporter: not far from paddock's mesquite home, the owner of this gunshot confirming he sold firearms to him but that all procedures were followed. he never gave an indication he was unstable or unfit. paddock's girlfriend is believed to be overseas but expected back soon to answer important

when she returns, this is what she'll see. the boarded up garage. this is what's left of the garage door. and even though the fbi have left the scene, police here in mesquite are keeping close watch over paddock's home since it could contain more key evidence. >> kenneth moten there in mesquite. let's talk about the gunman with our former fbi and contributor. the headline, 41 guns. perfectly, as far as you know, perfectly legal to buy all of those guns, and nothing in his background would have prevented him from buying those, correct? >> that's correct. and here's the thing. this is the problem with the gun laws. yes, if you don't have a conviction, criminal case that would prevent you from purchasing a gun, you could then purchase it. but the problem we're seeing is that just because you don't have a criminal conviction doesn't necessarily mean you are able to handle

out and kill people the way this guy did. that is one of the issues. the mental health issue that people are having that goes under the radar, his brother, his brother makes it seem like he had no problems. clearly he had a problem. his brother just didn't know paddock. that's the issue is that it's not just about the criminal conviction. it's about the mental health issue. and that's something we have to look at going forward. >> in terms of the investigation now, i know it's early, but usually even by now we start hearing things like this person had extremist views or they were on some sort of no-fly list. at one point or another authorities were tracking them and stopped. it sounds like in this case, there's nothing so far. >> nothing so far. no social media footprint from what we can tell. they did gather a computer. we've got to see what the computer says, but we have to look at what we do know. we do know he filed a lawsuit against one of the casinos several years ago.

supposed millionaire. did he have financial difficulties? that's something that has to be examined in the investigation. those things would easily cause someone to go over the edge, why is it if you're having these kind of problems you're going to go out and create such carnage the way he did. >> i'm curious about one thing. we've talked many times, sadly, in these situations. we've talked after the attacks in paris, after san bernardino. is there something legal about this act that makes it not considered an act of terror? what's different here? >> the big difference, this is the key for any kind of terrorism. international terrorism, domestic terrorism. was the violent act done to influence a political agenda? we have no indication that he was trying to influence any kind of political agenda. we'll have to see whether the investigation develops something

like that whether he is leaning forward an anarchist view or anything like that. it's a brutal, violent act, not any kind of terrorism from what we can see. >> a counter terrorism official, and abc news contributor, steve, thank you so much. >> and slowly we're learning the names of those who lost their lives, including denice burditus of west virginia who was with her husband of 32 years. they were called high school sweethearts. they leave behind two children and their fifth grandchild is on the way. >> sonny melton of tennessee passed away while presenting his wife heather. sonny was a registered nurse. one friend calls him a sweet, kind spirit. >> rachel parker was one of two employees of the manhattan beach police department shot there. she passed away at a vegas hospital. friends call her enthusiasm for life infectious. >> sandy casey was a special

manhattan beach, california. remembered for her sense of humor and devotion to students. >> so many of them being remembered as they should. well, coming up, the chilling look inside the gunman's arsenal. the discovery inside the hotel room and what we're learning about the heavy artillery he used to end the lives of those 59 people. >> and see how jimmy kimmel weighed in last night on america's gun culture and who he says is really running america. i did everything i could to make her party perfect.

coming from at least one rifle functioning like an automatic machine gun. listen. the unmistakable sound different from anything we've heard from all other mass shootings, none of them involving fully automatic guns. >> we are still going through the search warrant actively at this time. but it's in excess of ten rifles. >> reporter: sources telling abc news, haddock had at least 16 rifles and handguns, one of them an assault rifle modified to act like a machine gun. rifles capable of piercing through police body armer. >> this is a classic weapons of mass destruction. >> reporter: hearing nearly 200 rounds fired. hundreds more within the coming minutes. with pauses. likely to switch weapons or reload. the killer perched more than 300 feet above. the crowd over 1,100 fight away. >> 22,000 people were gathered

it's about common sense. common sense says no good will ever come from allowing a person to have weapons that can take down 527 americans at a concert. >> the nra did not make any comments. and has not issued any statement about the las vegas shooting. but he teared up. you see it coming from his eyes because it is personal for him coming from vegas. turning to the crisis in puerto rico. more federal help is streaming into the island. >> along with the troops and civilians handing out water and food. a number of native sons and daughters. >> "despacito" singer, luis fonsi and ricky martin helped unload items from a plane. gloria estefan toured the area and gave a few employments of levity. >> 5% of puerto ricans have power, and less than 40% of cell phone service has been
