for the gold and each other's hearts. it's thursday, october 5th. from abc news, this is "world news now." we begin with breaking news. three american service members have been killed in action in africa. officials say the army green berets died being ambushed while on a patrol in nigeriaer. >> 400 u.s. personnel are in niger. >> and we're learning more about the las vegas shooter. his arsenal and his actions leading up to the horrific attack. >> newly-released video captured the sheer panic and horror as people rushed from the venue. police say they have evidence that the shooter had actually planned to escape and that there was no suicide note in his hotel room.

out if he had any help. matt gutman has more on the preparation that went into the attack and the security guard who took a bullet trying to stop it. >> reporter: police body cam video showing officers risking their own lives amid unceasing gunfire. >> get down! go that way! get out of here! there's gunshots coming from over there, go that way! >> reporter: with sirens blaring and bullets flying, officers huddle behind a wall, trying to pin point the source of the mayhem. >> the mandalay bay out of a window. >> reporter: exhibiting extraordinary calm, those officers directing concert-goers away from the shooting toward safety. >> this way, this way, this way. go, go, go, go, go, go, that way, that way, that way, that way! >> reporter: it would be an hour before officers breached stephen paddock's luxury suite. he'd been holed up in that ar

these photos revealing the destructive power. this assault rifle one of 12 outfitted with a bump stock. it allows it to fire continuously, like an automatic weapon. this video demonstrating how it works. on the tip of the rifle, a flash hider, making its fiery blast difficult to spot. and in the corner a pile of 17 mag sheens holding 100 rounds each, 1700 bullets. he installed his own surveillance cameras. one on the cart and on the peephole, all rigged so he could see police approaching. and now we're learning he spotted a hotel security guard. >> he was advancing through the room when he struck the security guard. >> reporter: that security guard jesus campos is called a hero. somehow he was able to get away and tell the tactical team that paddock was in room 135. an hour later, they breach the door and discover him already dead. federal law enforcement sources

telling abc news they're investigating reports that the day before the massacre, he checked into multiple hotels overlooking the concert venue, and he may have looked for other opportunities. police revealing he rented a room in this building, right next to another music festival happening just the week before. and from this perch, he would have had a clear field of fire right down into those tens of thousands of people packed into that concert below. but for some reason he didn't pursue the plan. instead, he waited a week for the harvest festival. matt gutman, abc news, las vegas. >> and police also recovered 50 pounds of explosives in the gunman's car and another 1600 rounds of ammunition. >> we have an update on the hero security guard as well. jesus campos tells abc news he is fine and was just doing his job. and of course he did more than that. meanwhile, the shooter's girlfriend says she is

devastated by the attack and did not know he was planning it. she sat down with fbi agents after returning from the philippines and described her boyfriend as a kind and caring guy, saying that she was hoping for a quiet future with him. she acknowledged through her lawyer that she received money that he sent to the philippines, possibly $100,000. authorities say the shooter was recently seen with another woman. they're trying to track her down to see if there was an actual relationship or if she might be relevant to the investigation. >> and she thought that money was actually to buy a house in the philippines for her family. that's where her lawyer says. let's break down the latest development with former fbi special agent steve gomez. >> we knew he had this massive arsenal of guns. now they find explosives in his car. any leads on what his plans were for those? >> so the fact that it was in the car, which is down below at the bottom, and he's up in the 32nd floor, shooting, killing people, it makes you wonder why were those explosives in the vehicle? was

a while and then trying to get down to his vehicle and going to what would be a phase two of the attack? using the explosives somehow? that is definitely something that has to be examined, and when the sheriff talked about his thought process of escaping, that might lend credence to that, the fact of those explosives being in that vehicle. >> and steve, why do you think investigators believe he planned to escape? why didn't he? >> well, it's very interesting. that's a very important question to try to figure out. and what might have happened was he might have gotten so, saw that he was having such success with the shooting he might not have recognized that he was spending a lot of time doing that, even though it was only roughly about nine and a half, ten minutes. the fact that the security officer came and disrupted his plan, it that might have also thwarted his idea of now stopping and trying to leave, recognizing that there were people there. because after the security officer, two police officers

showed up. so then he might have seen that from the video cameras and recognized that okay, i can't leave now. now i've got to stay here and ultimately, he killed himself. >> now they say they think he had help, but they don't seem to have anyone specific in mind. what do you think is leading them in that direction and how do they pursue that? >> i think the complexity of this attack, the number of firearms, the explosives. and we're going to have to see if the explosives were actually capable of exploding and doing what he was intending for them to do. it's not easy to build these explosives. and there are instructions out there, but the fact that he had these explosives. unless he's some kind of expert, which we have no indication to indicate that, then it's very plausible there was someone helping him. also, you have so much information with regard to where he was going, you know, various different hotels. and his movements. you almost, you almost think that there had to been somebody else that was basically his partner in crime in this situation.

>> all right, if that person is out there, we certainly hope investigators find them soon. sounds like it they're on the right track. thanks so much. and president trump says he met some of the most amazing people during his visit there to las vegas. >> while he was there he met with first responders and survivors of the massacre. he called america a nation in mourning since the attack and spoke about the heroism of those who put their own lives at risk to help others. >> some were very, very badly wounded. and they were badly wounded because they refused to leave. they wanted to help others. because they saw people going down all over. and it's an incredible thing to do. tremendous bravery. >> and a photographer captured this image as the president flew back to washington. air force one flying past the broken windows of the mandalay bay hotel. and a new effort is under way in congress by the way to address bump stocks. that you heard matt gutman

explaining there. the las vegas gunman used those on several of his rifles. >> bump stocks are used to make a semi-automatic rifle perform like a fully-automatic one. they've been legally sold since 2010. but a new bill from senator dianne feinstein would ban bump stocks. some powerful republicans say they are open to considering that legislation. now remote areas of puerto rico are trying to recover from hurricane maria, and they're seeing more supplies arrive by air. a blackhawk helicopter delivered 5700 pounds of supplies yesterday. residents still need more food, water and medical supplies. according to fema, cell service has been restored to about 12% of the island. two-thirds of grocery and big box stores are open along with 70% of gas stations. five former living presidents are set to appear together at a hurricane relief concert, deep from the heart of one american appeal takes part
