good morning from the studio 57 newsroom at cbs headquarters here in new york. good to be with you. i'm anne-marie greene. the motive for the deadliest mass shooting in modern u.s. history remains a mystery. the gunman killed himself as police stormed his las vegas hotel room. but not before he fired hundreds of rounds on concert goers below in what authorities believe was a long planned attack. here is the latest. at least 59 people were killed and 527 wounded or injured. the fbi has so far found no link to international terrorism. the gun fire lasted more than ten minutes and u.s. officials tell the associated press two of paddock's rifles had been modified to make them fully automatic. >> reporter: good morning. authorities are still trying to determine a motive but at least in these early stages paddock

does not seem to fit the typical profile we've seen of suspects in previous mass shootings. victims are still recovering, hundreds of them this morning and some of them are still fighting for their lives. the eiffel tower went dark. the empire state building lit with a rotating halo for gun violence awareness. there were tributes throughout the day, throughout the world for the victims of sunday night's shooting in las vegas. police say 64-year-old stephen paddock broke windows on the 32nd floor in mandalay bay and opened fire on a crowded music festival before killing himself. concert goers say the night will stay with them forever. >> a woman was shot in her neck and the blood was just coming out all over the place and she collapsed on the ground and then there was another woman next to her that her leg was shot. >> investigators say paddock acted alone.

they raided his nevada home monday. >> we have recovered 23 fire arms at mandalay bay and 19 fire arms at his home in mesquite. >> isis has claimed responsibility for the attack but law enforcement says it hasn't found any connection to back that up. the shooter's brother said paddock had no religious affiliation. >> he has no history of violence. he's been divorced twice. he's friends with both of his exes. >> reporter: police say they also found in paddock's car several pounds of ammonium nitrate, a fertilizer that can be turned into explosives. >> reporter: today local authorities with the assistance of the fbi and atf will continue to investigate the crime scene here as well as combing through evidence they've acquired at paddock's properties. >> thank you. victims of the las vegas shooting were remembered in vigils and services across the

country. >> it's okay to have fear in your heart, it's okay to mourn those you love. >> a candle light vigil was held last night at the university of nevada. a prayer vigil in bakersville, california, was held to remember the shooting victims and in gallup, new mexico, students gathered to remember a school secretary killed in the shooting. 22,000 las vegas concert goers made a panic run for their lives. they tried to escape by climbing over walls and each other. they hid behind trailers and they ran into hotel lobbies but amid the chaos and fear, strangers risked their lives to help each other. >> i tied my leg off and basically kept me from bleeding out so he saved my life. >> so many coming in so fast we did what's called damage control, which is really just stopping the process of dying.

>> the las vegas fire chief says he's never seen so many ambulances in one place at one time. and as we reported we still don't know why stephen paddock started shooting from a las vegas hotel window but we are beginning to learn a little bit more about his life. >> reporter: after stephen paddock checked into the mandalay bay resort last thursday investigators say he spent the next three days gambling in the casino and he stock piled a mixture of handguns and rifles in a large suite. two of the guns were on tripods. police and the fbi are now trying to determine a motive. >> we're shocked, horrified, completely dumbfounded about this. >> eric paddock, the killer's brother says he was interviewed by investigators for about four hours. >> the fact that he had those kind of weapons is just -- where the hell did he get automatic weapons? >> anything --

>> nothing. no religious affiliation, no political affiliation. no, he just hung out. >> stephen paddock was an accountant. family members say recently he was a professional gambler who had won large jackpots. he was also a licensed pilot who had rented and sold multiple properties over the last four decades. paddock's father was once on the fbi's most wanted list, the 1969 notice described him as a bank robber who was psychopathic and considered armed and very dangerous. stephen paddock's only run-in with law enforcement was this 2009 parking ticket. >> it was well planned out and i took a lot of strategic thinking. >> profiler says paddock may have been planning the attack for years. he had a view of the concert and he probably had gone to other rooms and chose specifically this room.

so there was surveillance that likely occurred before this event. >> a search of paddock's home turned up additional weapons, thousands of rounds of ammunition and explosives. isis claimed responsibility for the attack but investigators say so far they have found no link between paddock and the terrorist group. cbs news, washington. >> president trump plans to travel to las vegas tomorrow to meet with victims and victims' relatives. he called the massacre an act of pure evil. >> our unity cannot be shattered by evil. our bonds cannot be broken by violence and though we feel such great anger at the senseless murder of our fellow citizens, it is our love that defines us today. >> the president has ordered flags at all public buildings flown at half staff. and the las vegas massacre renewed democrat calls for stricter gun control laws.

john is in new york with more. >> reporter: good morning to you. before sunday night's shooting the republican controlled congress had been moving forward on legislation to ease fire arms restrictions. so far, democratic calls for tougher gun laws have fallen on deaf ears. >> there's a time and place for a political debate, but now is the time to unite as a country. >> anyone who says this debate now is too soon, it's already too late. for at least 58 people in las vegas and hundreds of others who were wounded. >> following other mass shootings including those in colorado, connecticut and florida, congress failed to take action on gun control, a bipartisan bill on background checks failed in the senate four years ago amid strong opposition from gun groups including the nra. 13 years ago the federal assault weapons ban expired. it might have outlawed some of the guns used in the vegas attack.

and just before the las vegas assault, some republicans were pushing legislation to loosen fire arms restrictions including one to ease regulations on gun silencers. yesterday, speaker of the house, paul ryan showed no interest in tightening gun laws. he issued a statement saying the whole country stands united in our shock, in our condolences and prayers. >> if we will not restrict access to guns that are weapons of war, restrict access from people who shouldn't have these guns then -- then we are simply setting ourself for this to happen again. >> i think that we can have those policy conversations but today is not that day. >> well, before sunday the worst mass shooting in modern u.s. history was at the pulse nightclub in orlando last year. 49 people were killed. the nra has pulled its television ads set to air in virginia today in support of

republican candidates running for state office. >> thank you very much. coming up on the morning news now, helping the wounded. how some concert goers became first responders as they jumped into action to save the injured. this is the cbs morning news. ea. and there's no. sugar. added. cranberry pineapple 100% juice. the next big thing to hit the juice aisle. cranberry pineapple 100% juice. but on the inside, i feel like chronic, widespread pain. fibromyalgia may be invisible to others, but my pain is real. fibromyalgia is thought to be caused by overactive nerves. lyrica is believed to calm these nerves. i'm glad my doctor prescribed lyrica. for some, lyrica delivers effective relief for moderate to even severe fibromyalgia pain. and improves function. lyrica may cause serious allergic reactions, suicidal thoughts or actions.
